Insulation device of sliding bearing for vertical motor

Abstract

The invention provides an insulation device of a sliding bearing used in a vertical motor. The device comprises a case, a thrust head, a guide bearing pad and a thrust pad, wherein, the case is vertically arranged on a motor shell by a motor rotating shaft; the thrust head and the guide bearing pad are adapted to the motor rotating shaft, and the thrust pad is fixed on an extension board at the bottom of the case by a guiding shoe fillet by a connecting plate and an insulating padding plate; the thrust head is combined by a shaft housing and a seating; the shaft housing is fixed with the seating by a bolt and the insulating padding plate; the joint of the shaft housing and the bolt is provided with an insulation ring sleeve; and the joint of the shaft housing and the seating is provided with an insulation jacket layer. The invention adopts the technical proposal that the insulation device is embedded on the thrust head to ensure that the insulation device is higher than oil level and is not affected by lubricant quality, thereby overcoming the defect that shaft current generated by the existing bearing corrodes Babbitt surfaces of the thrust pad and the axial guide bearing pad. The insulation device is applicable to sliding bearings used for various vertical motors.

Description

technical field [0001] The invention relates to an insulation device of a sliding bearing for a vertical motor. Background technique [0002] The insulating backing plate in the existing bearing insulating device is under the shoe guide seat, the position is very low, and it is completely immersed in lubricating oil. Requirements: When the insulation resistance is affected by the quality of the lubricating oil, in the long-term working environment, the lubricating oil will continue to grow impurities such as metal particles that have fallen off due to bearing wear and tear. After reaching a certain level, the insulation performance will decline until invalidated. Contents of the invention [0003] In view of the above situation, the object of the present invention is to provide an insulating device for sliding bearings for vertical motors, which can not only keep the bearing insulation resistance value stable under the environment of continuous operation, but also prevent...
