A bidirectional locking method for bearing outer ring

Abstract

The invention discloses a two-way locking method for the outer ring of a bearing, which comprises the following steps: the first step is to prepare a locking device; the second step is to open stepped holes evenly spaced on the end surface of the bearing seat of the housing to install the locking device; The third step is to insert spring washers when installing each set of locking devices, so that the locking devices have the function of anti-loosening; the fourth step is to install a set of locking devices in each locking device installation hole, which can realize the bearing The outer ring has the functions of axial positioning and radial automatic locking; the fifth step is to install the bearing into the bearing seat of the housing, which solves the problem that the matching state of the outer ring of the bearing and the locking device cannot be visually adjusted. The above method not only solves the problem of movement and running of the outer ring of the bearing, but also improves the utilization rate of the axial space of the high-power gearbox, and plays an important role in increasing the power density of the gearbox.

Description

Technical field [0001] The present invention relates to a locking method, and more particularly to a bidirectional locking method of a bearing outer ring. Background technique [0002] The gear shaft is one of the main components of the wind turbine, the source of the ship, etc., and at both ends are fixed to the gearbox housing. When the gear shaft is mounted between the gear shaft, the gearbox is rotated when the gearbox is operated, and the gear shaft rotates about the support of both end bearing, which is heated during the rotation of the bearing ball in the race, so that the housing and the bearing The mating gap will be larger and larger, resulting in a bearing bearing hole relative to the housing bearing hole, so that the bearing outer ring is relatively wear, that is, the bearing running ring, which causes the gearbox to be uncomfortable, resulting in the gearbox If the damaged damage, slight bearing damage affects the life of the bearing, and severe bearing damage affect...

AI Technical Summary

Problems solved by technology

[0006] This kind of bearing outer ring positioning method needs to reserve a length in the axial direction of the inner space of the gearbox, which is the sum of the thickness of the bearing baffle and the length of the indexing pin, resulting in a large amount of redundancy in the inner space of the gearbox, which makes the gearbox capacity upgrade The axial length cannot be compressed during the design process, which has become one of the bottleneck technologies for increasing the power density of the current gearbox
