Abstract
The invention discloses a planet half-shaft gear gasket which comprises a gasket body (1). The gasket body is of a ball shell structure and is made of plastic. A pair of workpiece through openings (1a), a pair of small holes (1b) and a pair of large holes (1c) are formed in the gasket body (1), wherein the workpiece through openings (1a) are of a circular structure, the center connecting line of the workpiece through openings passes through the circle center of the gasket body (1), the center connecting line of the small holes (1b) passes through the circle center of the gasket body (1), and the center connecting line of the large holes (1c) also passes through the center of the gasket body (1). The planet half-shaft gear gasket brings convenience to the installation of workpieces. Moreover, due to the fact that the gasket body (1) is made of plastic, the gasket body (1) does not need heat treatment like spring steel, so that the gasket is prevented from cracking, and the service life of the gasket is further ensured. Moreover, friction between workpieces and the gasket is small, and noise is naturally small, so that the defect of a traditional structure is well overcome.
Description
Technical field
The invention belongs to speed changer field, specifically, relate in particular to a kind of planetary side gear pad.
Background technique
Existing planetary side gear pad is plane structure or spherical shape, and during installation, two differential gears and two planetary pinions are respectively equipped with a pad, and the material of pad is spring steel, and pad adds man-hour requirement, carries out nitriding treatment on surface.
The defect of existing pad is: 1,, owing to adopting 4 independent pads, it is not very convenient installing; 2, the material due to pad is spring steel, it is not very stable so not only causing heat treatment, easy through hardening when nitriding treatment is carried out on the surface of pad, thereby cause the fragility of pad very large, during use, be easy to occur breaking, and because pad and gear are metalwork, the friction between them and noise are just larger so.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of planetary side gear pad, wants to overcome the defect of conventional construction.
Technological scheme of the present invention is as follows: a kind of planetary side gear pad, is characterized in that: comprise clout body (1), this clout body is spherical shell shape structure, and the material of clout body (1) is plastics; On described clout body (1), have pair of workpieces by opening (1a), a pair of aperture (1b) and a pair of macropore (1c), wherein workpiece is round structure by opening (1a), and this pair of workpieces passes through the center of circle of clout body (1) by the line of centres of opening; The line of centres of a pair of described aperture (1b) is by the center of circle of clout body (1), and the line of centres of a pair of described macropore (1c) is also by the center of circle of clout body (1).
While adopting this pad, planetary pinion and differential gear enter the inside of clout body (1) by opening (1a) by two described workpiece, and the two ends of planet pin are supported on respectively in corresponding two apertures (1b), two side gear shaft are supported on respectively in corresponding two described macropores (1c), such this pad is with regard to the integrated function of 4 conventional spacers, and the installation of workpiece is simple and convenient.Because the material of clout body (1) is plastics, so just need not as spring steel, need heat treatment, thereby prevent that pad from splitting, and then guarantee working life of the present invention, and workpiece and friction of the present invention less, noise is also naturally less.
Adopt above technological scheme, the installation of workpiece is not only convenient in the present invention, and because the material of clout body (1) is plastics, so just need not as spring steel, need heat treatment, thereby prevent that pad from splitting, and then guarantee working life of the present invention, and workpiece and friction of the present invention less, noise is also naturally less, thereby has overcome well the defect of conventional construction.
As preferably, on the inwall of described clout body (1), have two ring-shaped steps (1d), the position of these two ring-shaped steps is corresponding macropore (1c) described in each respectively, and the line of centres of the line of centres of these two ring-shaped steps (1d) and two macropores (1c) is on same straight line.
Adopt above structure, the present invention can position differential gear well.
For the ease of selection, and take into account rigidity and the elasticity of material, the trade mark of described clout body (1) material therefor is AROG6, and its composition is PA66+30% glass.
For the ease of the present invention is arranged in differential casing, the special breach (1e) that is provided with on described clout body (1), this breach (1e) is communicated with two described workpiece by opening (1a).
Adopt above structure, can make the present invention there is certain deformation performance, to this pad is installed.
Beneficial effect: the installation of workpiece is not only convenient in the present invention, and because the material of clout body (1) is plastics, so just need not as spring steel, need heat treatment, thereby prevent that pad from splitting, and then guarantee working life of the present invention, and workpiece and friction of the present invention are less, and noise is also naturally less, thereby overcome well the defect of conventional construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
