Design and application of a bearing dismounting device for rail transit cars
The research on the bearing dismounting method and device for rail transit cars is very important to the efficiency and quality of rail transit product manufacturing and maintenance.Aiming at the bearing dismounting problem of a certain domestic rail transit car,this paper designs a self-adaptive dismounting device based on the analysis of the existing bearing dismounting methods.Finite element analysis of the key structural components is carried out by constructing a three-dimen-sional model,and the stiffness and strength of the device are verified through application.The application results show that the dismounting device can effectively improve the working efficiency,ensure the integrity of the bearing,and effectively a-void the strain of the bearing and the axle.
