A kind of high-speed overload power transmission lubrication feeding mechanism being applicable to submarine navigation device

The present invention proposes 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, fuel reserve tank, work oil tank and suction booster; Oil header sends into lubricating oil pump draw lubricating oil from fuel reserve tank after, and oil cooler sends into user to be lubricated, lubricating oil pump connection work oil tank by after the lubricating oil cooling sent into, and 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.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.
