Description

Technical Field

[0001] The utility model relates to the technical field of bearing repair tools, in particular to a special tool for disassembling a universal bearing. Background Art

[0002] The removal of bearings is a process that requires skills and appropriate tools to ensure that the bearings or surrounding components are not damaged. In the prior art, there is a lack of a special tool that can quickly and non-destructively remove bearings. A special tool for removing universal bearings that replaces the traditional manual puller is used. The traditional puller grabs the outer diameter of the bearing and pulls it outward, while the universal bearing can be easily damaged by pulling it outward. Referring to CN117773835A, a reliably positioned bearing puller and its working method are disclosed, and a convenient universal bearing removal tool is designed. Utility Model Content

[0003] The utility model aims to provide a tool for disassembling a universal bearing, so as to solve the problem of lack of a tool for non-destructive and quick disassembly of the universal bearing.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A tool for disassembling a universal bearing comprises a pulling frame, a puller screw and a bearing pulling pad; the pulling frame is a door-shaped structure; pad mounting platforms are arranged at both ends of the front of the pulling frame; a pulling rod screw hole is arranged on the top of the pulling frame; a puller screw is arranged inside the pulling rod screw hole; a U-shaped groove is arranged on the pad mounting platform; a bearing pulling pad is inserted into the U-shaped groove; a boss is arranged at the bottom of the bearing pulling pad; the boss is inserted into the pad mounting platform.

[0006] Furthermore, the surface of the puller screw is provided with long threads; a slot is provided at the front end of the puller screw; the slot is a circular structure; and a fixed cone is inserted into the slot.

[0007] Furthermore, a bearing slot is arranged on the top of the bearing pulling pad; the bearing slot is arranged in an arc-shaped structure.

[0008] Furthermore, the bearing drawing pads are provided with different curvatures and different diameter sizes.

[0009] Furthermore, the tail of the puller screw is arranged in a hexagonal structure.

[0010] Furthermore, a rough friction layer is provided on the inner wall of the bearing slot.

[0011] Compared with the prior art, the utility model can achieve one of the following beneficial effects:

[0012] 1. The pulling frame is arranged in a door-type structure; pad mounting platforms are arranged at both ends of the front part of the pulling frame; a pulling rod screw hole is arranged on the top of the pulling frame; a puller screw is arranged inside the pulling rod screw hole; a U-shaped groove is arranged on the pad mounting platform; a bearing pulling pad is inserted into the U-shaped groove; a boss is arranged at the bottom of the bearing pulling pad; the boss is inserted into the pad mounting platform, so that the pulling frame with the door-type structure is used as a support point, and the puller screw is used in conjunction with the bearing pulling pad to quickly eject and disassemble the bearing to be disassembled, which solves the problem that the traditional puller is to hold the outer diameter of the bearing and pull it outward, while the universal bearing is easy to damage the bearing by pulling it outward, thereby improving the disassembly speed of the bearing and facilitating use.

[0013] 2. The surface of the puller screw is provided with a long thread; a slot is provided at the front end of the puller screw; the slot is a circular structure; a fixed cone is inserted into the slot, which can achieve stable engagement with the screw hole of the pulling rod through the long thread, ensuring the stability of the pulling process, and the fixed cone supports the disassembly bearing to ensure stability. When actually needed, the fixed cone can also be removed and replaced with a positioning plate.

[0014] 3. A bearing slot is arranged on the top of the bearing pulling pad; the bearing slot is arranged in an arc-shaped structure, which can facilitate the fixing of the bearing pulling pad through the arranged bearing slot, and the opening direction of the bearing slot is opposite to the force direction, thereby ensuring stable force.

[0015] 4. The bearing pulling pads are provided with different curvatures and different diameter sizes, and it is possible to achieve by setting the bearing pulling pads into multiple pieces with different diameters. According to actual use needs, the diameter of the disassembled bearing can be matched, and the bearing pulling pads of corresponding diameter can be selected to better cooperate with the bearing and grip it, thereby facilitating the disassembly of the bearing.

[0016] 5. The tail of the puller screw is set as a hexagonal structure, which can facilitate the use of a sleeve or a jackhammer to rotate it, thereby increasing the disassembly speed.

[0017] 6. A rough friction layer is arranged on the inner wall of the bearing slot, which can effectively increase the friction between the bearing pulling pad and the bearing to be disassembled, tightly clamp the bearing, and quickly remove the bearing. BRIEF DESCRIPTION OF THE DRAWINGS
