Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly, in particular to a high-efficiency bearing disassembly tool. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] Most of the existing efficient bearing disassembly tools are for disassembling and assembling outer bearings, but not inner bearings. The inner bearing fits tightly with the bearing seat. Traditional disassembly is to abut the inner bearing with claws, and then pull the inner bearing out through intermittent and repeated pulling. The disassembly efficiency is low, and continuous pulling will cause the claws to collide with the inner bearing and cause damage. Utility Model Content

[0008] Furthermore, the bottom ends of the connecting columns are connected together with abutment rings, and the provision of the abutment rings facilitates increasing the area of ​​the connecting columns and avoiding losses to the outer side of the inner bearing.

[0009] Furthermore, the mounting seat is circumferentially connected with a plurality of guide rods, and the fixing seat is relatively connected with a plurality of guide holes, and the guide holes are slidably matched with the guide rods to facilitate guiding the up and down movement of the mounting seat.

[0010] Furthermore, the lifting assembly includes an outer shell connected to the fixed seat, a worm and a worm wheel that cooperate with each other are rotatably connected in the outer shell, a knob is connected to the worm, and a first screw is rotatably connected to the mounting seat. The first screw penetrates the fixed seat and the outer shell and penetrates the first worm wheel through a thread. The worm is driven by the knob, and the worm drives the worm wheel. The worm wheel drives the first screw through the threaded connection to drive the mounting seat and the inner bearing upward, thereby pulling out the inner bearing.

[0011] Furthermore, the limiting assembly includes a second screw rod, which passes through the fixed seat and the first screw rod through a thread, the bottom end of the second screw rod is connected to a cone block, and the top end of the second screw rod is connected to a handle. By turning the handle, the handle drives the second screw, and the second screw drives the cone block to adjust up and down through the thread, so that the cone block can lift the claw to expand outward.

[0012] Furthermore, the claw is of a Z-shaped structure, which facilitates the claw to be set through the inner ring of the inner bearing. A triangular block is connected to the outer side of the bottom end of the claw, and the setting of the triangular block facilitates supporting the bottom of the inner bearing.

[0013] 3. Beneficial Effects
