Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly technology, in particular to a bearing disassembler. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the friction coefficient during their movement. During mechanical maintenance, bearings need to be disassembled frequently, and a bearing remover is required.

[0003] For example, the small bearing remover with the existing patent application number CN202021624829.6 comprises a bottom plate, a U-shaped groove is provided on the surface of the bottom plate, a cylinder is fixedly connected to the top of the bottom plate, a support rod is fixedly connected to the top of the cylinder, the support rod is threadedly connected to a threaded rod, a rotating handle is fixedly connected to the top of the threaded rod, a notch is provided at the bottom end of the cylinder, and a first slide rod and a second slide rod are respectively slidably connected to the two sides of the bottom plate. When the utility model is used, the bearing that is difficult to remove is placed between the first clamp rod and the second clamp rod, and then the rotating handle is rotated. At this time, the rotating handle drives the threaded rod to press down, thereby completing the bearing removal, greatly saving working time and improving working efficiency, and the first clamp rod and the second clamp rod slide with the bottom plate respectively through the first slide rod and the second slide rod, so that the first clamp rod and the second clamp rod can adjust the spacing, thereby removing bearings of different sizes, which is more convenient to use.

[0004] However, the above device still has some shortcomings in actual use. The bearing can only be disassembled by the first clamping rod and the second clamping rod. However, the bearings to be disassembled are of different sizes. It is not convenient to adjust the distance between the first clamping rod and the second clamping rod. It is not suitable for disassembly of bearings of different sizes and has limitations. Utility Model Content

[0005] To this end, the utility model provides a bearing remover to solve the problem in the prior art that it is inconvenient to remove bearings of different sizes.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bearing remover comprises a first mounting plate and a second mounting plate arranged on the top of the first mounting plate, wherein the first mounting plate and the second mounting plate are internally threadedly connected with a same threaded screw;

[0008] A common disassembly assembly is provided between the first mounting plate and the second mounting plate, which is used to abut against the outer rings of bearings of different sizes, so as to facilitate disassembly;

[0009] The disassembly assembly includes three movable claws, which are provided with a number of evenly distributed threaded holes. Adjustment rods are provided on both sides of one of the threaded holes, and the two adjustment rods are threadedly connected with fastening bolts for passing through the threaded holes. A second rotating rod is rotatably provided at the top of the movable claw.

[0010] Furthermore, three evenly distributed first receiving blocks are fixedly provided on the second mounting plate, and three evenly distributed second receiving blocks are fixedly provided on the first mounting plate, and the first receiving blocks and the second receiving blocks correspond to each other.

[0011] Furthermore, a first rotating rod is rotatably provided between the ends of the two adjusting rods away from the movable claw, and the first rotating rod passes through one of the second receiving blocks and is rotatably connected to the second receiving block, so that the adjusting rod can rotate around the first rotating rod in the second receiving block.

[0012] Furthermore, the second rotating rod passes through one of the first receiving blocks and is rotatably connected to the first receiving block, so that the top end of the movable pulling claw and the first receiving block can rotate around the second rotating rod.

[0013] Furthermore, a same spring is fixedly provided between the first mounting plate and the second mounting plate, and the spring is sleeved on the outside of the threaded screw to facilitate the first mounting plate to bend and squeeze the spring to contract.

[0014] Furthermore, a hand-held rotating rod is fixedly provided at the top of the threading screw, and the hand-held rotating rod is arranged on the top of the second mounting plate, so that the hand-held rotating rod can be rotated to drive the threading screw to rotate, and the first mounting plate is fixedly provided on the threading screw.

[0015] The utility model has the following advantages:

[0016] By setting up the disassembly assembly, the staff takes the first mounting plate, unscrews the fastening bolts according to the size of the bearing to be disassembled, so that the adjusting rod connects to the threaded holes in different positions, and then fixes one end of the adjusting rod through the fastening bolt threaded connection, and then aligns the bottom end of the threaded screw with the center point of the bearing. The staff manually prys the first mounting plate to squeeze the spring and move it up along the threaded screw. During this process, the first mounting plate moves up to drive the adjusting rod to rotate around the movable claw, so that the top end of the movable claw rotates around the first supporting block through the second rotating rod, so that the three movable claws expand, thereby making the bottom ends of the three movable claws touch the outer ring of the bearing. After the staff lets go, the first mounting plate will move down under the elastic action of the spring, so that the three movable claws are clamped on the outer ring of the bearing, and then the hand-held rotating rod is rotated to realize the disassembly of the outer ring and inner ring of the bearing. It is suitable for bearings of different sizes and improves the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS
