Insulated seal end caps for motor shaft bearings

Abstract

The invention provides an insulated sealing end cover of a motor rotating shaft bearing. The insulated sealing end cover comprises an insulating cover; the right end of the insulating cover is fixedlyconnected with an outer lining plate through four long-foot bolts; a sealing mechanism is installed on the inner wall of the outer lining plate, and the two ends of the sealing mechanism are providedwith compensation mechanisms along the inner wall of the outer lining plate. According to the insulated sealing end cover of the motor rotating shaft bearing, since the insulating cover is symmetrically provided with two fixing holes which are through left and right, the outer lining plate is fixedly installed at the right end of the insulating cover, and the upper end and the lower end of the right end surface of the outer lining plate are vertically provided with correcting columns, so that the fixing holes are connected to a bearing seat through bolts, and the bearing is sealed. Six evenly-spaced ring stopping devices are vertically arranged at the ring edge of a shaft groove, four evenly-spaced insulation posts are arranged at the inner groove ring edge of the insulating cover, and electric conduction through a shaft rod can be avoided.

Description

technical field [0001] The invention relates to the technical field of wind power generation, and more specifically relates to an insulating sealing end cover of a motor rotating shaft bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. The sealing end caps of the existing rolling bearings are usually set at the upper and lower ends of the rolling bearings, such as one in the patent application CN201721369235.3 A bearing sealing end cover, compris...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the present invention provides an insulating sealing end cover of the motor shaft bearing, through structural and functional improvements, to solve the problem of the existing bearing sealing end cover during use and the continuous rotation of the shaft. , the bearing sealing end cover is also constantly vibrating, and the problem of poor sealing is prone to occur, resulting in poor lubrication effect, unable to make the bearing fully lubricated, resulting in reduced bearing life. In addition, the existing bearing end cover It is also very easy to contact with external objects. Once touched, it is very easy to cause electric shock
