Problems solved by technology

The existing lubrication system does not have an emergency lubrication function. When the external oil circuit of the main reducer is damaged or the radiator fails and oil leaks, the main reducer will lose its lubrication conditions and will fail quickly when it is running without oil

Abstract

The invention is an emergency lubricating device for a main reducer, which includes a lubricating oil filter, a main pump pressure control valve, a main pump, a cooling fan and a lubricating oil radiator. The oil suction port of the main pump is lower than that of the main pump, and the oil outlet of the oil delivery pipe of the auxiliary pump is directly connected to the lubricating oil filter and leads to the internal oil circuit of the main reducer. After passing through the device of the present invention, the main reducer successfully passes the 4-hour emergency lubrication test on the stand, so that the main reducer can work safely for 1 hour under the condition of emergency lubrication.

Description

An emergency lubricating device for a main reducer technical field The invention relates to an emergency lubricating device for a main reducer, which belongs to the technical field of mechanical lubricating. Background technique With the development of the domestic helicopter industry and the needs of military equipment construction, the reliability requirements for the main reducer of the helicopter are getting higher and higher, for example: the escape requirements after the helicopter is shot in a war. The existing lubrication system does not have an emergency lubrication function. When the external oil circuit of the main reducer is damaged or the radiator fails and oil leaks, the main reducer will lose its lubrication conditions and will quickly fail when it runs without oil. Contents of the invention The present invention is designed to provide an emergency lubricating device for the main reducer aiming at the problems existing in the equipment of the prior art, a...
