Reducer bearing lubrication structure

Abstract

A reducer bearing lubricating structure in the technical field of reducer, comprising a bearing arranged in a reducer housing, a bearing baffle and a reducer shaft, wherein the inner ring of the bearing is installed on the reducer shaft, and one side of the bearing is provided with a bearing stop The bearing baffle is fixed on the reducer housing, and the reducer housing also serves as a bearing seat; the bearing baffle includes a baffle shoulder against the bearing, and the baffle shoulder is along the shaft of the reducer on the side away from the bearing. Axially extending and retracting along the radial direction of the reducer shaft to form a lip baffle; the bearing baffle cooperates with the reducer housing and the bearing seat to form a bearing oil chamber, which is opposite to the bearing oil chamber on the reducer housing Equipped with oil guide groove. The invention assembles a lubricating oil storage mechanism at the position of the bearing to accommodate enough grease, so that the bearing can be lubricated in a stable oil bath when it is in operation, and the lubricating effect is improved, which is beneficial to the miniaturization design of the reducer.

Description

technical field [0001] The invention relates to a technology in the field of reducers, in particular to a bearing lubrication structure of a reducer. Background technique [0002] The inner bearings of the reducer are all open bearings. In the conventional design, an oil guide groove is provided on the reducer housing, and the oil guide groove guides the lubricating oil introduced by the gear of the reducer to the bearing to lubricate the bearing. [0003] At present, the development of new energy vehicles in the market has put forward miniaturization requirements for the reducer, resulting in a very compact structure of the components in the reducer (such as figure 1 As shown), the assembly position of the bearing is often difficult to meet the optimal design, and the amount of lubricating oil introduced by the oil guide groove is insufficient, resulting in poor lubrication of the bearing. [0004] The above problems can be solved by improving the bearing performance, but...

AI Technical Summary

Problems solved by technology

Of course, it can also be solved by increasing the forced lubrication of the oil pump, but adding the oil pump will not only increase the production cost, but also increase the difficulty and complexity of the system layout, which deviates from the original intention of miniaturization
