Definitions
- the invention relates to a method and a device for shaping and inserting shaft windings with web sections connected by winding heads in rotor and stator laminations of electrical machines.
- US Pat. No. 4,864,715 describes a method for shaping and inserting shaft windings with web sections connected by winding heads into a rotor-like transmission tool, in which the shaft windings are cut off from a shaft winding strip continuously formed from winding wire.
- the winding wire is alternately laid around the right or left side surface of shaping projections formed in a row on a continuously driven, endless conveyor chain, by shaping rollers actuated by tappets.
- the wave winding tape is then brought freely through the air tangentially to the rotor-like transmission tool.
- the shaft windings are displaced from the radially open grooves of the transmission tool into radially open grooves of a rotor or stator laminated core.
- a disadvantage of this method is the complicated and lengthy shaping operation of each individual shaft of the shaft winding by means of four wire guides in the form of ram-operated shaping rollers, which are used one after the other.
- a plurality of shaft windings in a desired relative arrangement cannot be introduced into the transmission tool at the same time.
- the difficulty in producing such a stator is that the strong rectangular wire, the width of which corresponds to the slot width, is difficult to deform in a conventional winding and drawing-in process and normally the winding heads protruding from the end of the stator laminated core due to the large number of them on the circumference overlapping coil turns and the poor deformability of the coil wire add up to an excessively large radial width, which can hardly be reduced practically with conventional winding-head forming tools.
- the invention is therefore based on the object of providing a method and a device which can be used to produce shaft windings in a simpler manner from relatively thick winding wire and to insert them into rotor or stator laminated core assemblies.
- the above object is achieved in terms of method in that in one work step in each case a plurality of shaft windings with a certain number of shafts cut from a continuously shaped shaft winding band are placed in a rod-shaped pickup and are essentially tangential to a rotor or stator laminated core or a rotor-like transmission tool each brought up with radially open grooves and during a rotary movement of the laminated core or transmission tool and a circumferential speed corresponding, essentially tangential relative movement of the band-shaped shaft windings, the web portions of which are pressed into the grooves.
- the invention offers the advantage that a multitude of different arrangements of stator windings can be produced with only two very simple molding processes. It is only necessary in a first step to continuously wind the winding wire into a flat wave, i. H. into a wave winding band. This is particularly advantageous with rectangular wire because twisting can be avoided. Then only the cut flat wave windings have to be collected in a rod-shaped transducer in the desired relative arrangement and then continuously bent from the essentially tangential position in the same direction to a ring with the relatively large radius of curvature of the ring-shaped arrangement of the wave winding in the laminated core , Strong deformations and jams, such as when axially pulling in pre-wound shaft windings, no longer occur.
- the device proposed according to the invention for carrying out the new method has a shaping device for shaping shaft windings and is characterized by a rod-shaped pickup for the shaft windings, which train on a rotor or stator laminated core or rotor-like transmission tool, which can be driven in rotation by a rotary drive, is arranged essentially tangentially with grooves open radially on the outside, a drive for the relative advancement of the rod-shaped transducer with the shaft windings accommodated therein and / or the laminated core or transmission tool along a guide with a speed corresponding to the peripheral speed of the laminated core or transmission tool and by guiding or pushing elements, by means of which the web sections of the shaft windings brought up to the laminated core or transmission tool can be successively displaced from the rod-shaped pickup and inserted into the radially open grooves.
- This device has the advantage that it is fundamentally independent of which wave shape, length and relative position to one another have the shaft windings to be introduced into a rotor or stator laminated core. It can therefore be used for a variety of different winding designs. If the shaft windings are to be introduced into a rotor or stator laminated core with radially open grooves, i.e. into an outer stator or the rotor of an external rotor motor or generator, the above-mentioned transmission tool is used with an additional operation to first to displace the transmission tool generated windings radially outward from its grooves into the grooves of the outer stator or external rotor.
- FIG. 2 twelve shaft windings inserted into the rod-shaped pickup according to FIG. 1, which are subsequently introduced together into a rotor or stator laminated core or into a rotor-like transmission tool;
- FIG. 3 shows a plan view of a system for forming and introducing shaft windings into stator laminated core assemblies consisting of several sub-devices;
- FIG. 4 shows a side view of a device for continuously shaping a wave winding tape with a connected embossing device
- FIG. 5 shows a top view of the molding device and the embossing device according to FIG. 4;
- FIG. 1 A first figure.
- 6A, B, C are side views, with reference to FIG. 4, of the device for forming a wave winding tape, the parts of the device being shown in different stages during the formation of a wave winding;
- Fig. 7 is a plan view from above of one part of the device for molding the Wave winding tape forming wire guide
- FIGS. 1 and 2 are simplified side views of a rotor or stator laminated core or a transfer tool with radially open grooves in cooperation with the rod-shaped pickup and guide elements shown in FIGS. 1 and 2 for transferring the shaft windings from the pickup into the laminated core or into the transfer tool;
- FIG. 9 shows a schematic plan view of the rod-shaped sensor and the cut guide elements according to FIG. 8, the shaft windings lying in the grooves of the sensor also being shown for the sake of the drawing;
- FIG. 10 shows a simplified partial cross section through a rotor-like transmission tool in a concentric position and assumed in the transmission of shaft windings in a stator lamination stack
- FIG. 11 shows a simplified longitudinal section through the transmission tool according to FIG. 10.
- the shaft winding 10 shown in FIG. 1 has a certain number of waves, depending on the number and occupancy of the slots of the rotor or stator laminated core to be fitted with it, which is formed by parallel web sections 12 and gable-shaped winding tion heads 14 are formed.
- the connection ends of the wave winding are designated 16.
- the wave winding 10 shown covers every sixth slot of a stator laminated core, the web sections 12 extending through the stator slots and the gable-shaped winding heads 14 protruding from the front of the stator laminated core. Between two stator slots occupied by the shaft winding 10, five stator slots each remain free in the exemplary embodiment, into which further such shaft windings 10 are inserted. In total, e.g. B.
- the radially open grooves 18 of a stator core 20 each have eight layers or layers - which here means a wire layer in a groove 18 - are present.
- this number is only an example.
- the grooves 18, which are rectangular in cross section, could in each case already be filled with four wire layers of a thicker rectangular wire.
- other numbers of layers may also occur, it also being possible for two or more wire layers in a slot to be formed by a single, integral shaft winding 10. This is e.g. B.
- FIGS. 1 and 2 It can also be seen from FIGS. 1 and 2 that a wave winding of twice the circumferential length in the middle of this can be folded and folded in such a way that two web sections lie one above the other and the winding heads are arranged opposite one another.
- one of two identical shaft windings of simple circumferential length could be turned over, placed on the other and electrically connected to it at one end. This also gives a distributed wave winding with two web sections in each slot and with winding heads arranged directly opposite one another.
- the insertion into the grooves of the rod-shaped pickup 22 can also be carried out in such a way that the six shaft windings, which form a wire layer, are first inserted with only half their length. The sequence is then reversed over the second half of the length of the rod-shaped pickup 22, so that the winding wire last inserted with its first half is inserted first into the second half of the pickup 22, the penultimate wave winding as the second, etc. that in the winding heads of the second wire layer in the stator, the wire crossings are on the other half of the gable.
- Fig. 2 illustrates the very uniform arrangement of the winding heads of a multi-layer winding.
- FIG. 3 shows a top view of an overview of a complete production system for winding and introducing shaft windings into stator laminated cores.
- 24 and 24 ' denote two shaping devices operating in parallel, in each of which a winding wire drawn off from a supply roll 26 or 26 "is continuously formed into a shaft winding band, from which the shaft windings shown in FIGS. 1 and 2 are obtained as sections 3, in each case an embossing station is designated in which the winding heads of the shaft windings are shaped by stamps and matrices in such a way that they can be guided past one another in different planes cut to the required length from the continuously generated wave winding tape and the connector ends 16 are pulled out.
- the shaft windings 10 are inserted into the slots of the rod-shaped pickup 22 in the order and arrangement provided, with as many wire layers in each slot as together in a single working step in the grooves of one
- Rotor or stator laminated core or a rotor-like transmission tool can be introduced.
- a conveyor system is provided with pallets, each of which carries a rod-shaped pickup 22 with grooves.
- the corresponding pallet 32 or 32 ' moves into the transfer station shown at 34, and another pallet 36 or 36' with an empty rod-shaped transducer 22 moves in the charging station 30 after.
- the shaft windings are first transferred from a rod-shaped pickup 22 in the example to a rotor-like transfer tool with radially open grooves.
- FIGS. 8 and 9 For details, reference is made to FIGS. 8 and 9 below.
- the filled transfer tool is then pivoted from a turntable 40 into an insertion station 38, in which the rotor-like transfer tool is inserted into the bore of a stator lamination stack in such a way that its radially inside open grooves are aligned with the grooves of the transfer tool, so that radially movable sliders align the shaft windings be able to push the transmission tool radially into the grooves in the stator core.
- the turntable 40 then pivots the stator laminated core into a compression station 42, in which the group of shaft windings introduced first in the stator slots is pushed or pulled radially outward and the winding heads are compressed.
- a finished wound stator lamination stack is then transported from the turntable 40 to an output station 44 and removed or fed out there.
- the partially wound stator laminated core is again brought into the insertion station 38 and equipped with the second or further group of shaft windings. Then there is again a compression process in the compression station 42 before the stator lamination stack is removed in the output station.
- the wave windings formed in the shaping device 24 ′ may be expedient to design the wave windings formed in the shaping device 24 ′ with somewhat narrower winding heads than in the shaping device 24 and in the transfer station 34 and the insertion station 38 alternately first a group of wave windings from the shaping device 24 and then a group of wave windings from the Molding device 24 'by means of suitable transfer tools in the stator introduce ket. With the different width winding heads, the different radii of the shaft windings can be taken into account after they have been inserted into the stator laminated core.
- FIGS. 4 and 5 show the molding device 24 in more detail and FIGS. 4 and 5 also the embossing device 28.
- the main parts of the molding device 24 are two continuously rotating disks 46, 48 arranged axially next to one another, each with a the circumferential surface protruding form projections 50.
- the disks 46, 48 cooperate with the continuous production of a shaft winding tape 52 with a wire guide which is mounted in a step-by-step manner rotating about a horizontal axis immediately next to the circumference of the disks 46, 48.
- the formation of the winding wire fed from the supply 26 into the shaft winding band 52 is best seen from the simplified schematic illustration in FIGS. 6A, 6B and 6C.
- the beginning of the winding wire denoted by 56 according to FIG. 6A is temporarily clamped to a shaping projection 50 of the left-hand disk 46 or held in another way and placed around the next shaping projection 50 of the right-hand disk 48 that follows in the circumferential direction as a loop ,
- the wire guide 54 which consists of a rotatably mounted carrier 55, for. B. in the form of a disk or a bar and diametrically opposed near the outer circumference, axially projecting towards the disks 46, 48, there is a driver pin 58, 60 that begins to turn according to the directional arrow 62, in the example according to FIG.
- the driver pin 58 against the winding wire 56 coming from the supply 26 and begins to form loops on its circumference.
- the driver pin 58 also guides the winding wire around a projection 50 of the left disk 46, on its circumferential surface is held by a plunger 64 which is arranged centrally on the carrier 55 or extends non-rotatably through the carrier 55 and is pushed axially against the molded projection.
- the plunger is preferably formed at its free end with a retaining lug 66 which pushes the wire onto the molded projection 50 sufficiently far.
- a loop is formed on the above-mentioned shaped projection 50 of the disk 46 and on the driver pin 58 at the same time.
- a guide plate 70 shown in FIG. 4 is provided, which overlies the winding wire 56 guides the next projection 50 away.
- the processes described above are then repeated when, with continued rotation, the driving pin 60 reaches the position in which the driving pin 58 is located in FIG. 6A.
- the molded projections 50 on the two disks 46 and 48 are arranged relative to one another in a gap, the circumferential distance between a molded projection 50 on one disk and the immediately following molded projection 50 on the other disk being approximately as follows is as large as the diameter of the winding wire 56. Since the continuous rotary movement of the disks 46 and 48 is matched to the interrupted rotary movement of the wire guide 54 so that a wire loop is successively transferred to each form projection 50 of both disks 46, 48, the overall result is uninterrupted Wave winding band 52.
- a suitable stepping mechanism e.g. in the form of a Maltese cross drive.
- the wire withdrawal from the wire supply 26 contains a wire brake. Therefore, the winding wire 56 stands during the formation of
- the projections 50 in the two circumferential rows on the disks 46, 48 on the circumferential area on which the shaft winding tape 52 from the loop formation point to the point of the run-off from the disks 46, 48 is transported initially by a certain amount which is sufficient, a relatively high one for which
- the roller can rotate uniformly about a straight axis. If, on the other hand, two disks 46, 48 are used instead of a wide roller, the molded projections 50 do not need to perform a relative axial movement, because it is sufficient to support the disks 46, 48 in such a way that the distance between two obliquely opposite one another during the rotational movement Form projections that carry the shaft winding tape, first enlarged and then reduced again.
- the axes of rotation of the two disks 46, 48 can be inclined to the side to drop outwards for this purpose. Then the distance between the two disks 46, 48 and thus between the obliquely opposite molded projections 50 is greatest at the top, smallest at the bottom and at the loop formation point approximately as large as at the point where the shaft winding band 52 is separated from the disks 46, 48. running. On the way from the loop formation point to the drainage point, the intermediate distance between the molded projections 50 increases, as desired, and then becomes smaller again.
- other bearings for the disks 46, 48 could also be selected which produce a wobbling movement of the disks with the stated effect.
- molded projections 50 with a corresponding cross-sectional shape.
- the latter could also be replaced, for example, by three pins each, which are located at those points where the laterally outermost corners of the molded projections 50 are located.
- the manufacture of the pins is less expensive than the manufacture of the molded projections 50.
- the shaped projections 50 can also have another shape suitable for winding heads instead of the gable-shaped cross section. The same applies to the arrangement of the pins used alternatively.
- a deflecting plate arranged in the space between the disks 46, 48 can ensure that the shaft winding band 52 reliably detaches from the molded projections 50 and initially a freely hanging one Loop 74 forms before the shaft winding belt 52 is gripped by an endlessly drivable transport belt 76 with drivers 78 attached on its outside and transported to the embossing device 28.
- the freely hanging loop 74 fluctuates in length during operation and forms a buffer store which compensates for the uneven take-off speed due to the idle times of the transport belt 76 in relation to the uniform conveying speed of the disks 46, 48.
- the loop 74 can optionally be supported by a flexible guide 80 which is resiliently resilient under weight load, in order to prevent the shaft winding band 52 from becoming too long due to its own weight.
- the embossing station 28 has the function of deforming the winding heads 14 perpendicular to the plane of the shaft winding strip 52 in such a way that the winding heads overlapping in the stator laminated core in the assembled state do not impede one another and the shaft windings 10 have the same wire layer, eg. B.
- the radially outermost wire layer can be introduced as stress-free as possible in their respective position or position in the stator slots, so that not only during the insertion process do the crossing winding heads have to be pressed together so strongly that they deform and the web sections of the shaft windings 10 can assume their intended position in the stator slots.
- the punches 82 and dies 84 are dimensioned and designed such that one or more winding heads 14 can be pressed out in whole or in part relative to the main plane of the shaft winding strip 52 upwards or downwards during each stamping operation. In this way, with a sufficient number of stamps, all winding heads 14 of a wave winding 10 can be shaped simultaneously with a single stroke. Alternatively, there is the possibility of forming the winding heads 14 of a wave winding 10 with fewer punches 82 in several strokes. Normally, the transport belt 76 will be stopped during the shaping, during which time the disks 46, 48 convey the wave winding tape 52 generated into the loose loop 74 serving as a buffer store.
- the punches 82 and dies 84 can also be operated on the fly in connection with a longer transport belt 76 so that they are moved parallel to the transport belt 76 during the molding process. Such a mode of operation does not require the free hanging loop 74.
- cutting tools (not shown) are attached, which cut through the shaft winding band 52 at predetermined locations in order to obtain shaft windings 10 of a certain length. The wire ends of the cut shaft windings are pulled out by grippers, not shown, to the connection ends 16 shown in FIGS. 1 and 2.
- the web sections 12 can be formed into a rectangular cross section by wave windings produced from round wire.
- the embossing device 28 is optionally followed by a further work station in which a long wave winding 10 is folded back onto itself by machine or by hand in such a way that a wave winding which is half as long is formed.
- two wave windings 10 can be superimposed to form a distributed wave winding and electrically connected to one another at one end.
- crossing two or more wave windings which are to lie next to one another in different slots, at certain points in such a way that on one part of their length the one wave winding lies under another wave winding, but on another part of its length lies above ,
- the shaft windings 10 are inserted into the transverse slots of the rod-shaped or rack-shaped pick-up 20, which is also shown in FIGS. 1 and 2 and in FIGS. 8 and 9, at the charging station designated by 30 in FIG. 3.
- an endless conveyor belt in the manner of the conveyor belt 76 conveys a plurality of shaft windings 10, the winding heads 14 of which are guided in the guide rails 86 shown in FIG. 1, in the respectively predetermined one Position above or below certain transverse grooves of the rod-shaped transducer 22.
- the shaft windings 10 are inserted into the transverse grooves by raising or lowering the guide rails 86 or alternat_Lv by raising or lowering the rod-shaped transducer 22.
- FIG. 8 shows the transmission of the shaft windings from the rod-shaped pick-up into a rotor magazine or rotor-like transmission tool 88 with grooves 89 open radially on the outside. This process takes place in the transmission station designated 34 in FIG. 3. Instead of the transmission tool 88, a rotor or stator laminated core with radially open grooves could also be present there.
- the rod-shaped pickup 22 is oriented tangentially for the transfer process with reference to the rotor-like transfer tool 88 or a rotor or stator laminated core present in its place, the grooves of the rod-shaped pickup 22 and the grooves 89 of the transfer tool 88 being included their openings face each other.
- Transducer 22 and the transfer tool 88 are matched to one another in such a way that the two opposite grooves are each aligned with one another at the tangential contact point.
- the Ubertragungswerkmaschine leads during the transmission process 88 a rotational movement in the counterclockwise direction about a fixed axis, while the rod-shaped receiver 22 with the environmental 'peripheral speed of the transfer tool 88 along a not shown linear guide in a straight line from right to is pushed to the left.
- U-shaped guide elements 90, 92 in plan view press the shaft windings 10 held up to then by guide rails corresponding to the guide rails 86 in the grooves of the sensor 22 in the area of the tangential contact point and the area behind in the direction of movement out of the grooves of the sensor 22 1, 2 and 9 is narrower than the length of the web portions 12 of the shaft windings 10, the U-shaped guide members 90, 92 can be on both sides next to engage the rod-shaped pickup 22 on the outer regions of the web sections 12 and the winding heads 14 in order to successively displace the web sections from the grooves of the pickup 22 and to push them into the grooves of the transfer tool 88.
- Transfer tool 88 needs very simple movement drives for the transfer process. If one is willing to do without it, one can also use a rod-shaped pick-up 22 curved upwards or downwards with a certain radius with reference to FIG. 8, because even at the point of contact of the transmission tool 88 an im there is substantial tangential alignment and relative movement. In all cases, while the other part is stationary, either the transfer tool 88 or the rod-shaped pickup 22 can be combined in a ned movement are performed so that a transmission movement allowing the transmission of the shaft windings comes about.
- FIGS. 10 and 11 show a partial cross-section of the rotor magazine or transmission tool 88 on a larger scale and its longitudinal section during the radial insertion of the shaft windings 10 into the radially open slots 18 of a stator lamination stack 20.
- the stator lamination stack 20 is used for this transmission process in the rotational position axially placed on the transmission tool 88 or inserted into the bore of the stator 20 such that the radially inside open grooves 18 are aligned with the radially outside open grooves of the transmission tool 88. Then, the shaft windings seated in the grooves of the latter are displaced radially outward into the grooves 18 of the stator core 20 by radially outwardly seated, lamellar slides 94 in the same grooves.
- FIG. 10 shows an example of a groove 18 into which four wire layers of shaft windings have already been inserted during an earlier transmission process, while four further wire layers of shaft windings are still seated in the corresponding groove 89 of the transmission tool 88 and radially in the next transmission process by the associated slide 94 must be pushed outwards into the aligned stator.
- Another stator groove with a rectangular cross section is already completely filled with eight wire layers of shaft windings with a matching cross section.
- rods corresponding to disks with an infinitely large diameter with molded projections 50 attached thereto or, analogously to the roll mentioned, a rod with two rows of cross-displaceable molded projections 50 in cooperation with a wire guide 54 could also be used for the shaping device form band-shaped wave windings 10.
- all other parts and measures described above could remain unchanged or be taken over analogously
