Multifunctional bearing assembling and disassembling tool

The utility model discloses a multifunctional bearing assembling and disassembling tool which is used for solving the problem of difficult disassembling of bearings. The technical scheme is as follows: the multifunctional bearing assembling and disassembling tool comprises a bolt, a concave seat and a convex ejector block, wherein one end of the convex ejector block is thin, and the other end of the convex ejector block is thick; the concave seat, the convex ejector block and the bolt are in thread fit; and the depth of the concave seat is slightly larger than the thickness of a bearing. The multifunctional bearing assembling and disassembling tool utilizes the bolt, the concave seat and the convex ejector block to disassemble the bearing easily. The size of the concave seat and the convex ejector block can be set according to the bearings of different types; the multifunctional bearing assembling and disassembling tool has small volume, is convenient to operate, not only saves manpower and time, but also can be configured according to the bearings of different types, and improves the maintenance efficiency of the equipment.
