Abstract

The invention discloses an end cover structure of a motor bearing, which comprises a bearing, an insulating part and a supporting part, wherein the insulating part is positioned between the bearing and the supporting part and is used for insulating and isolating the bearing and the supporting part; the bearing is used for driving the rotating shaft connected with the bearing to rotate under the control of the motor; and the supporting part is used for supporting and limiting the bearing through the insulating part. According to the end cover structure, the bearing and the supporting part are insulated and isolated through the insulating part, the insulation resistance is high, the circulation path of bearing current can be effectively blocked, damage of the bearing current to the bearing is prevented, and therefore the service life of the bearing is prolonged.

Description

technical field [0001] The present invention relates generally to the electromechanical field. More specifically, the present invention relates to an end cover structure of a motor bearing. Background technique [0002] At present, the bearings of most motors on the market do not use insulation measures or the insulation measures are relatively poor, which may cause damage to the bearings and the shaft due to shaft voltage and shaft current. Shaft voltage refers to the potential difference between the two ends of the shaft or between the shaft and the bearing, and its voltage waveform has complex harmonic pulse components. When the shaft voltage is low, the bearing oil film can play a good role in insulation and lubrication. However, when the shaft voltage rises to a certain value due to some reasons, it may break down the oil film discharge, which will destroy the stability of the oil film, make the grease gradually deteriorate and lose the insulation and lubrication effe...
