Description

A kind of auxiliary lubricating oil pump
Technical field
The present invention relates to engine lubrication system, a kind of specifically auxiliary lubricating oil pump.
Background technique
Engineering machinery or special car at work, when engine is in biggish tilt angle, the shallow Qu Huiji of oil sump A large amount of machine oil is stayed, causes oil sump depth area oil mass inadequate, lubricating oil pump is emptied, and output engine oil pressure is inadequate, and engine is caused to damage It is bad.
General solution is to increase by a section auxiliary pump in lubricating oil pump, sucks back oily bottom in the shallow area's machine oil of oil sump accumulating The area Ke Shen, and utilize the pressure oil lubrication auxiliary pump of lubricating oil pump main pump itself.
And auxiliary pump can not be increased in the case where space is inadequate, in lubricating oil pump, it is necessary to one auxiliary be installed in other positions Pump, but since auxiliary pump can have the case where being emptied for a long time, this just determines that auxiliary pump cannot lean on the pressure of itself glossy It is sliding, need a stable pressure oil-source to carry out active lubrication.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of auxiliary lubricating oil pump, which has to carry out itself The structure of lubrication.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of auxiliary lubricating oil pump, including sliding tooth Wheel, the pump housing, pump cover, pump shaft, the both ends of the pump shaft are arranged in respectively in the axis hole of the pump housing and pump cover;On the pump housing and pump cover It is equipped with oil leab, the oil of main oil gallery for being introduced at the axis hole of the pump housing and pump cover by the oil leab.
The further technical solution of the present invention is: bushing, each bushing are pressed in the axis hole of the pump housing and pump cover Length be respectively less than the length of axis hole, an annular groove and one and the annular groove phase are equipped on the hole wall of each axis hole The axial strip groove of friendship, the oil leab are connected with the annular groove, and the pressure oil from main oil gallery can successively lead to Cross the gap that oil leab, annular groove, strip groove are flowed between pump shaft and bushing.
In one embodiment, the pump shaft includes driving shaft and driven shaft, is equipped with driving gear on the driving shaft, Driven gear is installed on the driven shaft.
The beneficial effects of the present invention are: the oil leab will be for that will lead due to being equipped with oil leab on the pump housing and pump cover The oil of oil duct is introduced at the axis hole of the pump housing and pump cover, ensures that obtain steady and sustained profit between pump shaft and axis hole in this way It is sliding.In further technical solution, since the length of bushing is less than the length of axis hole, and it is equipped with mutually on the hole wall of axis hole The annular groove and strip groove of connection, intermediate annular groove are communicated with oil leab, can be thus introduced into the pressure oil of main oil gallery Gap between pump shaft and bushing, is lubricated pump shaft and bushing.
Detailed description of the invention
