Description
Technical field
The present invention relates to the submarine navigation device technical field, be specially a kind of lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device.
Background technique
The dynamic lubrication system general work principle of submarine navigation device is: lubricating oil is stored in the housing fuel tank, draw the lubricating oil supercharging by lubricating oil pump after, enter each rubbing surface, each spring bearing and motion gear place, return at last in the housing fuel tank and recycle.
The lubricated supply system that existing submarine navigation device uses is drawn the lubricating oil supercharging by lubricating oil pump and is carried out pressure lubrication, as with reference to figure 1.It is lower that this lubricated supply system only is only applicable to rotating ratio, to lubricating oil supply short time insensitive piston-engined lubrication system that stops; Because the lubricating oil pump inlet pressure is non-constant, the pressure of oil system and flow are also unstable; When the aircraft attitude changed, possible short-term existed the lubricating oil pump suction not oil and produces the oil-break phenomenon.This lubrication system is comprised of oil header 1, lubricating oil pump 2, lubrication duct 3, transmission system 4, oil cooler 7.Oil cooler 7 is the fuel tank of whole lubrication system with the seal space that the front and back dividing plate forms.
Its working principle is: when piston engine is worked, driving power train and lubricating oil pump turns round, lubricating oil pump 2 carries out oil suction by oil header 1, then the supercharging lubricating oil is to the pressure and the flow that need, after by lubrication duct 3 lubricating oil being delivered to oil cooler 7 and cooled off, enter at last 4 pairs of bearings of power train and gear etc. and locate to be lubricated.
Because the turbine power system power of now submarine navigation device employing is large, rotating speed is high, longevity of service, requires the supply of lubricating oil to stablize, and the phenomenon that stops can not occur.The lubricating oil pressure of existing hydrodynamic lubrication supply system and flow potentially unstable, when the aircraft attitude changed, possible short-term existed the lubricating oil pump suction not oil and produces the oil-break phenomenon.In power train at a high speed, can cause fretting wear face lubrication and cooling not enough, the friction surface temperature sharply raises and causes each rubbing surface to damage, and causes the movement parts serious wear, finally causes complete machine to lose efficacy.
Summary of the invention
The technical problem that solves
Large for overcoming existing submarine navigation device turbo power unit power, rotating speed is high, longevity of service, and the supply of lubricating oil such as unstable may occur stopping phenomenon and the problem that causes kinetic friction spare to break down to cause complete machine to lose efficacy.The present invention proposes a kind of lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device, adopt lubricating oil pump and suction booster to stablize fuel feeding, and structure is adapted to existing submarine navigation device.
Technological scheme
Technological scheme of the present invention is:
Described a kind of lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device, comprise oil header, lubricating oil pump, oil cooler and fuel reserve tank, oil header is sent into lubricating oil pump draw lubricating oil from fuel reserve tank after, sends into after oil cooler cools off the lubricating oil of sending into and treats lubricated user; It is characterized in that: the described lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device also includes work oil tank and suction booster; Described lubricating oil pump connection work oil tank, the work oil tank connects oil cooler by suction booster; Have pressure relief valve on the work oil tank, pressure relief valve passes into fuel reserve tank.
Described a kind of lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device, it is characterized in that: the volume flowrate of lubricating oil pump is 3 times of suction booster.
Beneficial effect
The invention has the beneficial effects as follows: in lubricated supply system; by using lubricating oil pump 2, work oil tank 5, suction booster 6, pressure relief valve 8; realized that submarine navigation device all can be stablized and supplied lubricating oil under any working state; guaranteed the reliable, effectively lubricated of the positions such as high-speed bearing, each surface of friction pair; form lubricant film at each frictional abrasion surface; reduced friction factor, effects on surface forms protection, has guaranteed the long-time reliably working of high-power, high rotating speed driving mechanism.By oil cooler lubricating oil is cooled off simultaneously, reduced the temperature of lubricated component surface, prolonged the operating life of friction surface.The invention of this lubrication system so that turbo power unit can work, also is the lubricated solution that provides of the power plant of other types under high-power, high rotating speed, heavily loaded working state.That this invention also has is simple in structure, take the little characteristics in physical dimension space.
Description of drawings
Fig. 1: background technique lubricating fitting schematic diagram;
Fig. 2: structural representation of the present invention;
Wherein: the 1-oil header, the 2-lubricating oil pump, the 3-lubrication piping, 4-lubricates the user, the 5-oil tank of working, 6-suction booster, 7-oil cooler, 8-pressure relief valve, dividing plate before the 9-rear bulkhead, 10-, B-fuel reserve tank.
Embodiment
Below in conjunction with specific embodiment the present invention is described:
The lubricated feeding mechanism of high-speed overload power transmission that is applicable to submarine navigation device in the present embodiment comprises oil header 1, lubricating oil pump 2, lubrication piping 3, lubricated user 4, work oil tank 5, suction booster 6, oil cooler 7, pressure relief valve 8.
The cavity bottom that is formed by oil cooler 7 and gear-box rear bulkhead 9, front dividing plate 10 by oil hole, is injected into lubricant oil in the fuel reserve tank B, and reaches lubricant oil liquid level At The Height after the assembling of power plant gear-box is finished as fuel reserve tank B.After power plant are started working, start working by gear drive lubricating oil pump 2 and the suction booster 6 of driving mechanism.Lubricating oil pump 2 produces negative pressuren zone in the one side near oil header 1, and lubricating oil enters lubricating oil pump 2 by oil header 1.Lubricating oil enters work oil tank 5 by lubrication piping after lubricating oil pump 2 superchargings, again through suction booster 6 supply lubricating oil to oil cooler 7, the friction surfaces such as Bearing gear be lubricated and cool off through lubrication piping again through overcooled lubricating oil.Lubricant oil after the work finally flows in the fuel reserve tank B, thereby has realized the lubricated of whole system, has prevented that lubricating oil cutout phenomenon from not appearring in the small-scale underwater vehicle device when attitude changes, guaranteed the long-time reliably working of each motion component.The volume flowrate of lubricating oil pump is greater than the volume flowrate of suction booster in this lubrication system, and the volume flowrate of lubricating oil pump is 3 times of suction booster in the present embodiment.When work oil tank 5 lubricating oil pressures surpassed authorized pressure, lubricating oil passed through pressure relief valve 8 pressure releases in fuel reserve tank B, thereby the lubricating oil supply that has guaranteed lubrication system is stable.
