Use method of oil seal removal tool

Abstract

The invention discloses a use method of an oil seal removal tool. The use method comprises the following steps that a receding groove which is provisionally sealed and formed in the side wall of an oil seal is cleaved; a U-shaped groove in a supporting base is placed on the end surface of a bearing, and according to the distance between the receding groove and the bottom of the U-shaped groove, a pull-out rod is moved in a hollow connection cylinder, so that a clamping disc at the tail end of the pull-out rod penetrates through the receding groove and directly makes contact with the inner wall of the oil seal; through the threaded cooperation between an outer thread and the inner wall of the connection cylinder, the pull-out rod is fixed into the connection cylinder; a nut on the connection cylinder is started to be manually rotated through a wrench or other pneumatic devices, so that the connection cylinder is matched with the nut in a threaded mode in a through hole and then moves upward till the oil seal is completely pulled out. By means of the use method, the parts can be detachably connected, the pull-out rod can still accurately penetrate through the receding groove and make contact with the inner wall of the oil seal aiming at bearings of different types, and the applicability of the use method is improved.

Description

technical field [0001] The invention relates to an LL type oil seal, in particular to a method for using an oil seal removal tool. Background technique [0002] The LL type oil seal is used for the sealing of the 353130B compact bearing, which can achieve the purpose of making the short shaft of the 353130B compact bearing less prone to bending and increasing the service life. Abrasive particles invade the bearing, which also makes the bearing have good sealing performance and improves the service life of the grease in the bearing. [0003] However, during the long-term operation of the locomotive, in order to ensure the stable operation of the locomotive, it is necessary to detect and replace the LL-type oil seal in time and regularly. During the replacement process of the LL-type oil seal, the temporarily sealed oil seal unloading groove is usually opened. Then use tools such as pliers to pull the oil seal out of the bearing. Since the press-fitting of the LL-type oil sea...

Problems solved by technology

[0003] However, during the long-term operation of the locomotive, in order to ensure the stable operation of the locomotive, it is necessary to detect and replace the LL-type oil seal in time and regularly. During the replacement process of the LL-type oil seal, the temporarily sealed oil seal unloading groove is usually opened. Then use tools such as pliers to pull the oil seal out of the bearing. Since the press-fitting of the LL-type oil seal is realized through a hydraulic press-fitting mold, the oil seal is tightly attached to the bearing. Manual operation requires a large amount of labor and increases the workload of the workers. , and the efficiency is low; another solution is to use large-scale precise automatic extraction equipment, but this method is expensive and unacceptable to ordinary enterprises
