Bearing module and bearing

Abstract

The invention provides a bearing module and a bearing. The bearing comprises a cage and a bearing guide ring; a radial gap is formed between the bearing guide ring and the cage; the bearing guide ringis provided with a guide ring gas guide hole; and the guide ring gas guide hole communicates with the radial gap, and extends to the outer surface of the bearing guide ring. In the working process ofthe bearing, external gas is provided to the bearing through a gas source, and the gas enters the radial gap through the guide ring air guide hole formed in the outer surface of the bearing guide ring, so that the friction caused by impact contact between the bearing guide ring and the cage can be prevented, and the service life of the bearing is prolonged.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of machinery, in particular to a bearing assembly and a bearing. Background technique [0002] Rolling bearings are precision mechanical elements that change the sliding friction between the running shaft and the bearing seat into rolling friction, thereby reducing friction loss. Rolling bearings include bearing inner rings, bearing outer rings, rollers and cages. The bearing inner rings are mounted on the shaft and rotate together with the shaft. The bearing outer rings are mounted on the bearing housing and generally do not rotate. There are raceways on the inner ring of the bearing and the outer ring of the bearing, and the cage guides and drives the rolling elements to roll on the correct raceway. [0003] When rolling bearings are working, for example, wheel set bearings and gearbox bearings widely used in the railway industry, the bearings are subject to great shock and vibra...

Problems solved by technology

However, large vibrations caused by emergency braking or bad road conditions are not common. It is not an economical way to reduce the impact by reducing the load-carrying capacity of the bearings. However, the impact of vibrations on the bearings cannot be ignored.
