Abstract

The invention discloses a high-speed motor end cover type sliding bearing assembly method. The method comprises the steps that a lower bearing base and an end cover mounting seam are in running-in, a bearing bush and a bearing bush base, and the bearing bush and a shaft are in double-surface running-in, and the magnitude of interference between the bearing base and the bearing bush can be measured by using a equal-altitude filler gauge and is adjusted, so that the bearing base is installed by using a sliding method, the bearing bush is installed by utilizing an oil lubricating method, the position of the bearing bush in the bearing seat can be adjusted by utilizing a tray rotating and center adjusting method, an upper bearing base and the lower bearing base can be positioned and fastened, and other parts are installed in position. According to the method, the occurrence times of undesired effects that when a high-speed motor is operated, the sliding bearing is high in temperature and subjected to bush burning and vibrates and the like can be reduced and even can be avoided, and the whole assembly quality of the motor end cover type sliding bearing can be promoted.

Description

technical field [0001] The invention relates to an assembly method of a sliding bearing, in particular to an assembly method of an end cover type sliding bearing of a high-speed motor. Background technique [0002] End-shield sliding bearings are mainly used in large and medium-sized high-speed motors, and their working performance and assembly quality directly affect the performance and service life of high-speed motors. The motor end cover type sliding bearing generally adopts a split mechanism, that is, the bearing seat of the sliding bearing includes the upper bearing seat and the lower bearing seat, and the bearing bush of the sliding bearing includes the upper bushing and the lower bushing. This split sliding bearing is easy to assemble and disassemble. The gap between the bearing bush and the shaft can be adjusted, and it is widely used. Generally, the main factor affecting the performance of the end cover sliding bearing is temperature change. When the high-speed sl...
