Problems solved by technology

The change of the wheel spacing will not affect the movement of the center of gravity of the whole vehicle, so after the axial movement of the shell, the bearing will be subjected to eccentric load, so that the load o...

Embodiment Construction

[0016] in figure 1 A bearing ring designed according to an embodiment of the invention is shown in. Here, the bearing ring is designed as a bearing outer ring 1. The bearing outer ring 1 is basically the same as the bearing outer ring of the rolling bearing in the prior art, that is, it has a circular ring shape and is composed of two radially extending end surfaces and an outer surface and an inner surface extending in the axial direction. Such as figure 1 As shown, shoulders 5 are respectively provided at the positions where the inner surface and the two end surfaces meet, which are used to limit the rolling elements 2 to the raceway area and act as an axial stop. When the bearing bears an axial load, the stop The shoulder can also carry axial forces. The inner surface between the two shoulders 5 is provided as a rolling surface for the rolling elements.

[0017] The difference between the bearing outer ring 1 designed according to the embodiment of the present invention and ...

Abstract

The invention discloses a bearing ring having opening grooves, and a bearing. The bearing ring has two end faces facing toward an axial direction and in opposite arrangement. Opening grooves penetrating into the bearing ring in the axial direction are arranged on at least one end face. The outer ring and/or inner ring of the related bearing are designed with the bearing rings having the opening grooves.

Description

Technical field [0001] The invention relates to a bearing ring for a bearing, which has two opposite end faces facing the axial direction. The invention also relates to a bearing with such a bearing ring. Background technique [0002] Rolling bearings, especially cylindrical roller bearings, are widely used in railways, steel rolling, large motors, wind turbines, etc. due to their high radial load and certain axial load capacity. [0003] For example, large ball bearing sets used in railway units, especially in train wheels, are placed in the housing of the axle box, and have a left bearing and a right bearing, the two bearings are aligned (coaxial) and two The bearing is symmetrically distributed with respect to the external load to ensure that the bearing bears a uniform load. Since different countries have different railway width standards, the distance between train wheels may be adjusted to meet the standards of different regions. Therefore, the bearing set can move axially...
