Abstract

The invention discloses a bearing lining and a gear box and relates to the technical field of gear transmission equipment. The lining comprises a lining body, an oil inlet hole and an oil return hole,wherein the lining body is provided with a through hole, the oil inlet hole is formed in the lining body, is communicated with the through hole and is formed in the radial direction of the through hole, and the oil return hole is formed in the lining body and is communicated with the through hole. The lining is advantaged in that the lubricating oil in a box shell is led into the through hole through the oil inlet hole formed in the bearing lining, the lubricating oil can be guided back into the box shell through an oil return hole formed in the bearing lining, so lubrication of a bearing isachieved, the service life of the bearing is prolonged, maintenance cost is reduced, the oil inlet hole is formed in the radial direction of the through hole, an oil inlet groove can be directly communicated with the oil inlet hole of the lining, the oil leakage risk is avoided, the oil inlet hole can be an unthreaded hole, the machining process is simplified, and production cost is reduced.

Description

technical field [0001] The present application relates to the technical field of gear transmission equipment, in particular, to a bearing bush and a gear box. Background technique [0002] In the bearing assembly process of gearboxes, especially rail transit subway gearboxes, the positioning of the bearings is generally achieved through the axle bearing bushes. assembly. [0003] In the prior art, after the bearing is installed in the axle bearing bush, it is difficult to lubricate, which shortens the service life of the bearing. Contents of the invention [0004] The purpose of the present application is to provide a bearing bush and a gearbox, which can realize the lubrication of the bearing and prolong the service life of the bearing. [0005] The embodiment of the application is realized like this: [0006] A bearing bushing, comprising a bushing body, an oil inlet hole and an oil return hole, the bushing body has a through hole; the oil inlet hole is arranged on th...
