Bearing

Abstract

The present invention relates to a bearing comprising: a bearing inner ring and a bearing outer ring; the sealing assembly is arranged between the bearing inner ring and the bearing outer ring, the sealing assembly is used for sealing the part between the bearing inner ring and the bearing outer ring, the sealing assembly comprises a conductive part (1), and the conductive part (1) is used for electrically conducting the bearing inner ring and the bearing outer ring. According to the bearing provided by the invention, the problem of pitting corrosion of the raceway can be avoided.

Description

technical field [0001] The invention relates to a bearing. Background technique [0002] The bearing seal assembly is arranged between the inner ring and the outer ring of the bearing to prevent external impurities from entering the inside of the bearing. [0003] In the prior art, the rollers, the inner raceway and the outer raceway are made of conductive metal. When the bearing rotates, a uniform grease film can be formed between the rollers and the raceway, and the grease usually has insulating properties. If the bearing is affected by voltage, for example, the rolling bearing on the axle box in the railway field, when the motor is working, since the electric filter cannot completely filter out the waveform, the residual voltage will affect the bearing. The grease film is located on one side of the roller and one side of the raceway, and gradually accumulates a voltage difference, which accumulates to a certain extent to form a high pressure drop, and then generates spar...
