Description
Technical field
The present invention relates to submarine navigation device technical field, be specially a kind of high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device.
Background technique
The dynamic lubrication system general work principle of submarine navigation device is: lubricating oil is stored in housing fuel tank, after drawing lubricating oil supercharging, enters each rubbing surface, each spring bearing and motion gear place by lubricating oil pump, finally returns housing fuel tank Inner eycle and uses.
The lubrication supply system that existing submarine navigation device uses, draws lubricating oil supercharging by lubricating oil pump and carries out pressure lubrication, as with reference to figure 1.It is lower that this lubrication supply system is only only applicable to rotating ratio, to the insensitive piston-engined lubrication system of lubricating oil supply short time cutout; Because lubricating oil pump inlet pressure is non-constant, the pressure of oil system and flow are also unstable; When aircraft attitude changes, there is lubricating oil pump suction and do not oil and produce oil-break phenomenon in possible short-term.This lubrication system is made up of oil header 1, lubricating oil pump 2, lubrication duct 3, transmission system 4, oil cooler 7.The seal space that oil cooler 7 and front and back dividing plate form is the fuel tank of whole lubrication system.
Its working principle is: when piston engine works, power train and lubricating oil pump is driven to operate, lubricating oil pump 2 carries out oil suction by oil header 1, then supercharging lubricating oil is to the pressure needed and flow, by lubrication duct 3, lubricating oil is delivered to after oil cooler 7 cools, finally enter power train 4 pairs of places such as bearing and gear and lubricate.
The turbine power system power adopted due to present submarine navigation device is large, and rotating speed is high, longevity of service, requires that sliding oil supplying must be stablized, can not occur the phenomenon that stops.The lubricating oil pressure of existing hydrodynamic lubrication supply system and flow potentially unstable, when aircraft attitude changes, there is lubricating oil pump suction and do not oil and produce oil-break phenomenon in possible short-term.In power train at a high speed, fretting wear face lubrication and cooling can be caused not enough, and friction surface temperature sharply raises and causes each rubbing surface to damage, and causes movement parts serious wear, finally causes complete machine to lose efficacy.
Summary of the invention
The technical problem solved
Large for overcoming existing submarine navigation device turbo power unit power, rotating speed is high, longevity of service, and sliding oil supplying, as instability, may occur cutout phenomenon and cause kinetic friction part to break down the problem causing complete machine to lose efficacy.The present invention proposes a kind of high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device, adopt lubricating oil pump and suction booster to stablize fuel feeding, and Structure adaptation is in existing submarine navigation device.
Technological scheme
Technological scheme of the present invention is:
Described a kind of high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device, comprise oil header, lubricating oil pump, oil cooler and fuel reserve tank, oil header sends into lubricating oil pump draw lubricating oil from fuel reserve tank after, and oil cooler sends after the lubricating oil cooling sent into into user to be lubricated; It is characterized in that: described in be applicable to submarine navigation device high-speed overload power transmission lubrication feeding mechanism also include work oil tank and suction booster; Described lubricating oil pump connection work oil tank, work oil tank connects oil cooler by suction booster; Work oil tank has pressure relief valve, and pressure relief valve passes into fuel reserve tank.
Described a kind of high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device, 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 lubrication supply system; by using lubricating oil pump 2, work oil tank 5, suction booster 6, pressure relief valve 8; achieve submarine navigation device and all can stablize supply lubricating oil under any working state; ensure that the position such as high-speed bearing, each surface of friction pair reliable, effectively lubricate; lubricant film is formed at each frictional abrasion surface; reduce friction factor, effects on surface forms protection, ensure that the long-time reliably working of high-power, high rotating speed driving mechanism.By oil cooler, lubricating oil is cooled simultaneously, reduce the temperature of lubrication component surface, extend the operating life of friction surface.The invention of this lubrication system, makes turbo power unit can work under high-power, high rotating speed, heavy duty work state, also for the lubrication of the power plant of other types provides solution.This invention also have structure simple, take the little feature in physical dimension space.
Accompanying drawing explanation
Fig. 1: background technique lubricating fitting schematic diagram;
Fig. 2: structural representation of the present invention;
Wherein: 1-oil header, 2-lubricating oil pump, 3-lubrication piping, 4-lubricates user, and 5-works oil tank, 6-suction booster, 7-oil cooler, 8-pressure relief valve, 9-rear bulkhead, dividing plate before 10-, B-fuel reserve tank.
Embodiment
Below in conjunction with specific embodiment, the present invention is described:
The high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device in the present embodiment comprises oil header 1, lubricating oil pump 2, lubrication piping 3, lubrication user 4, work oil tank 5, suction booster 6, oil cooler 7, pressure relief valve 8.
Lubricant oil, as fuel reserve tank B, by oil hole after power plant gear-box has assembled, has been injected in fuel reserve tank B by the cavity bottom formed by oil cooler 7 and gear-box rear bulkhead 9, front dividing plate 10, and reaches lubricant oil liquid level At The Height.After power plant are started working, started working by the gear drive lubricating oil pump 2 of driving mechanism and suction booster 6.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 supercharging, then supplies lubricating oil to oil cooler 7 through suction booster 6, carries out lubrication and cooling again through overcooled lubricating oil through lubrication piping to friction surfaces such as Bearing gears.Lubricant oil after work finally flows in fuel reserve tank B, thus achieves the lubrication of whole system, prevents small-scale underwater vehicle device not occur lubricating oil cutout phenomenon when attitudes vibration, ensure that the long-time reliably working of each motion component.In this lubrication system, the volume flowrate of lubricating oil pump is greater than the volume flowrate of suction booster, and in the present embodiment, the volume flowrate of lubricating oil pump is 3 times of suction booster.When oil tank 5 lubricating oil pressure that works exceedes authorized pressure, lubricating oil passes through pressure relief valve 8 pressure release in fuel reserve tank B, thus ensure that the lubricating oil supply of lubrication system is stablized.
Main feature of the present invention is in lubrication supply system, by using lubricating oil pump 2, work oil tank 5, suction booster 6, pressure relief valve 8, achieve axle system high-speed rotary in power plant fuel reserve tank then cause lubricating oil to rock, or in small-scale underwater vehicle device generation rolling situation, lubricating oil all can realize stable supply.When power plant work, rotary axis drives lubricating oil pump to extract lubricating oil from fuel reserve tank and is fed to work oil tank, ensures the stable supply of lubricating oil suction booster entrance lubricating oil, after being cooled, enters lubrication user and lubricates by oil cooler.Realize the high rotating speed of turbo power unit, long-time, high power ground reliably working.
