Horizontal bearing pressing system

Abstract

The invention relates to a horizontal bearing pressing system. The horizontal bearing pressing system comprises a base; a linear guide rail is fixedly installed in the middle of the base; two air cylinders are symmetrically installed on the two sides of the base; each air cylinder comprises a thrust rod; the end of the thrust rod away from the air cylinder body is fixedly connected with a press-fitting sleeve; three sliding blocks are connected to the linear guide rail in a sliding mode; limiting plates used for fixing the press-fitting sleeve are fixedly connected to the sliding blocks on thetwo sides; and a lifting V-shaped support used for horizontally supporting a rotor is fixedly connected to the sliding block in the middle. The horizontal bearing pressing system achieves simultaneous press-fitting of two bearings, is high in press-fitting precision, high in efficiency, low in cost and wide in application range, and is suitable for bearing press-fitting of different types of rotors and large-scale production lines. According to the invention, the linear guide rail and the sliding blocks which are high in precision are adopted, which ensures that the pressure in the bearing press-fitting process is always kept on the same straight line, and has an obvious effect of reducing shaft deformation caused by radial force borne by the rotor shaft in the press-fitting process.

Description

technical field [0001] The invention belongs to the technical field of electric motor cold pressure bearings, in particular to a horizontal pressure bearing system. Background technique [0002] The bearing is an important part of the motor, and its main function is to support the mechanical rotating body, reduce the friction coefficient during the movement, and ensure the rotation accuracy. The quality of the bearing directly affects the noise and life of the motor. Among them, the process of pressing the bearing into the rotor has a great influence on the bearing, that is, the quality of bearing pressing directly affects the assembly quality and service life of the motor. [0003] The existing method of manually pressing the bearing into the rotor based on experience cannot guarantee the dimensional accuracy, and often occurs that the bearing is over-pressed or the rotor shaft is bent, resulting in problems such as bearing damage, stuck operation, or abnormal noise, and t...
