Abstract

The invention discloses a hydraulic pump idle gear component. The hydraulic pump idle gear component comprises a hydraulic pump idle gear with a central shaft hole and flanging linings arranged in pairs, and the flanging linings comprise shaft hole inserting sleeves and flanging sides located on one ends of the shaft hole inserting sleeves. The flanging linings arranged in pairs are separately pressed both sides of the hydraulic pump idle gear through the shaft hole inserting sleeves, a plurality of oil drain slots are formed in the radial direction of the flanging sides, and installation chamfers are arranged on the outer sides of the other ends of the shaft hole inserting sleeves. An oil drain slot structure is designed on the flanging linings of the hydraulic pump idle gear component, when a gear assembly is rotated, lubricating oil can quickly cover the whole flanging side area through the oil drain slots to form an oil film, and the effects of lubrication and cooling are achieved.

Description

technical field [0001] The invention relates to the field of engine transmission, in particular to a hydraulic pump idler gear assembly. Background technique [0002] Due to the influence of factors such as installation location and lubrication conditions, the idler gear of the hydraulic pump has always been a fault-prone part. Due to the limited space, sliding bearings are generally used. However, due to a certain overturning force during operation to form a roll moment, local wear of the end face of the gear hub and the pressure plate, and failures such as oil leakage often occur, which seriously affect the service life of the parts. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the inve...
