Title:
DISMOUNTING DEVICE FOR TRACTION MOTOR BEARING AND METHOD APPLIED TO DISMOUNTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/093037
Kind Code:
A1
Abstract:
Disclosed is a dismounting device for a traction motor bearing. The dismounting device comprises a positioning mechanism for being fixedly arranged on a rotor assembly and a moving mechanism movably arranged relative to the positioning mechanism, wherein the positioning mechanism is provided with a positioning face (6), and the moving mechanism is provided with a matching face (7) for matching the positioning face (6), such that the rotor assembly can be positioned in the radial direction and the axial direction. Compared with the prior art, the dismounting device for the traction motor bearing provided by the present application avoids the dismounting process of a bearing after a rotor assembly and a stator assembly are separated, thereby simplifying the dismounting process of a traction motor bearing, reducing the configuration requirements and cost of human resources and material resources in a bearing dismounting process, shortening the dismounting time of the traction motor bearing, and improving the working efficiency. Further disclosed is a traction motor bearing dismounting method applied to the dismounting device of the traction motor bearing.
