Description

Technical Field

[0001] The utility model relates to the technical field of high-rod roller box positioning bearing bolt disassembly and assembly tools, in particular to a roller box positioning bearing bolt disassembly and assembly device. Background Art

[0002] Locating bearing bolts are mainly used to fix and locate bearings to ensure that the bearings maintain the correct axial and radial position during use to withstand the expected load and ensure rotational accuracy. The use and installation details of these bolts depend on the bearing type, application requirements and working environment.

[0003] The disassembly and assembly tools for positioning bearing bolts are determined by the type of bearing, installation position and specific working conditions. Choosing the right tools can not only ensure the smooth disassembly and assembly work, but also effectively prevent damage to bearings or bolts, improve work efficiency and ensure equipment safety. Before actual operation, you should carefully read the equipment manual to understand the recommended tool types and operating procedures. The roller box locking bolts are difficult to disassemble, and it is easy to damage the holes with a wrench. This type of wrench has only one force point on the front tip. If it is not placed properly or too much force is used, the disassembly hole will be deformed and scratched, causing destructive disassembly. This spare part is an imported spare part with a long supply cycle. Once it is damaged and there is no spare part, the spare part cannot be repaired.

[0004] Therefore, there is an urgent need to design a roller box positioning bearing bolt disassembly and assembly device to solve the problem that the existing wrench has a single force point when disassembling and assembling the positioning bearing bolt, which is easy to damage the disassembly hole and cause damage to the bolt.
