[0002] In mechanical equipment, when a bearing needs to be maintained or replaced, it is generally necessary to remove it from the shaft or the bearing seat. In order to facilitate disassembly, tools such as wrenches, hammers, and bearing removers are generally used in the prior art.

[0003] At present, the existing bearing removers are generally as follows Figure 1 As shown, it includes a disassembly frame 01, and claws 02 are symmetrically hingedly installed at both ends of the disassembly frame 01. An abutment screw 03 is threaded through the middle of the disassembly frame 01. When used, the existing technology can use the end of the abutment screw 03 to abut the end of the rotating shaft 04, and then use the claws 02 to grasp the outer edge of the bearing 05, and by rotating the abutment screw 03, the claws 02 are moved outward relative to the abutment screw 03, that is, the bearing 05 is pulled off the rotating shaft 04.

[0004] However, in actual use of the prior art, the disassembly frame 01 and the clamping claw 02 are movably connected and lack a limiting structure, so that the clamping claw 02 is easy to slip off the bearing 05 during use, which affects the disassembly efficiency and is inconvenient to use.

[0005] Therefore, the present application provides a bearing disassembly device to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a bearing disassembly device to solve the problem that when the existing bearing remover is in use, the claws are prone to slip off from the bearing to be disassembled, which affects the disassembly.

[0012] As a further preferred solution, one end of the movable column extends out of the end of the fixed tube and is detachably mounted with an abutment joint.

[0013] As a further preferred solution, one end of the movable column away from the abutment joint is connected to a cylinder, and the cylinder is fixed to a side of the frame away from the fixed cylinder.

[0014] As a further preferred solution, the abutment joint is made of rubber material, a stud is fixed on the abutment joint, and the stud is threadedly inserted into the end of the movable column to form a fixation.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the cooperation of the fixed cylinder, the movable cylinder and the connecting rod, the movable cylinder elastically connected to the frame can be used to drive the two claws to retract inward through the connecting rod, thereby keeping the two claws able to elastically clamp the bearing at all times, thereby effectively avoiding the problem of the claws and the bearing slipping and affecting the disassembly efficiency.

[0032] like Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a bearing disassembly device, including a frame 1, a handle 101 is fixed on the top of the frame 1 for holding, connecting plates 102 are symmetrically fixed on both sides of the frame 1, and grooves are provided at one end of the connecting plates 102 away from the frame 1, and claws 6 are rotatably installed in the grooves, and the two claws 6 are symmetrically arranged.

[0033] A fixed cylinder 2 is fixed in the middle of the frame 1, and a slidable movable column 3 is arranged inside the fixed cylinder 2. One end of the movable column 3 extends out of the end of the fixed cylinder 2, and a detachable abutment joint 4 is installed, so that the abutment joint 4 can be used to abut the surface of the rotating shaft in the middle of the bearing, and the end of the movable column 3 away from the abutment joint 4 is connected to a cylinder 5, and the cylinder 5 is fixed to the side of the frame 1 away from the fixed cylinder 2, which can drive the movable column 3 to move. Therefore, when the device is in use, the cylinder 5 can be used to control the extension and retraction of the movable column 3. Compared with the method of screwing the threaded column in the prior art, the drive control of the cylinder 5 is not only labor-saving, but also can avoid problems such as thread stripping due to long-term use.

[0034] At the same time, a slidable movable cylinder 7 is sleeved on the fixed cylinder 2, and the movable cylinder 7 is elastically connected to the frame 1. Connecting rods 8 are hingedly installed on both sides of the movable cylinder 7, and the ends of the two connecting rods 8 away from the movable cylinder 7 are respectively hinged to the inner sides of the two clamping claws 6. In specific implementation, in this embodiment, the second connecting ears 701 are symmetrically fixed on both sides of the movable cylinder 7, and the first connecting ears 601 are fixed to the inner middle parts of the two clamping claws 6, and the connecting rod 8 is hingedly installed between the second connecting ear 701 and the first connecting ear 601, so that the movable cylinder 7 can drive the two clamping claws 6 to open or contract and clamp through the connecting rod 8.

[0035] Among them, a spring 702 is connected to one end of the movable cylinder 7 facing the frame 1, and the spring 702 is connected to the outer edge surface of the frame 1. When the spring 702 pulls the movable cylinder 7 toward the frame 1, the two claws 6 can be driven to retract inward through the connecting rod 8, thereby keeping the two claws 6 able to elastically clamp the bearing at all times, thereby effectively avoiding the problem of the claws 6 and the bearing slipping off and affecting the disassembly efficiency.

[0036] In addition, if Figure 4 As shown, in this embodiment, the abutment joint 4 is made of rubber, and a stud 401 is fixed on the abutment joint 4, and the stud 401 is threadedly inserted into the end of the movable column 3 to form a fixation. The abutment joint 4 can reduce the wear of the end of the movable column 3 and facilitate the replacement of the abutment joint 4.

[0037] The working principle provided by the utility model is that the bearing disassembly device can utilize the movable cylinder 7 elastically connected to the frame 1 to drive the two claws 6 to retract inwards through the connecting rod 8 when in use, so as to keep the two claws 6 able to elastically clamp the bearing all the time, thereby effectively avoiding the problem of the claws 6 and the bearing slipping off and affecting the disassembly efficiency. After the claws 6 clamp the bearing, the cylinder 5 can be used to control the extension and contraction of the movable column 3, and the abutment head 4 abuts against the rotating shaft in the middle of the bearing to cooperate with the claws 6 to disassemble the bearing. Compared with the abutment disassembly method in the prior art that requires the threaded column to be screwed, the drive control of the cylinder 5 not only saves effort, but also avoids the problem of thread slippage.

[0038] In summary, the device can not only prevent the claw 6 from slipping off the bearing and affecting the disassembly efficiency, but also is simple to operate, labor-saving, and has a good overall use effect.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention.
