AI Technical Summary
Technical Problem
Conventional puller tools can easily damage electrical wiring when disassembling bearings of external rotor motors, leading to reduced maintenance efficiency and increased workload.
Method used
A bearing disassembly aid tool was designed, including a support block and a limiting component. The support block is used to support the puller's push rod, and the limiting component is inserted into the fixed shaft to prevent the push rod from directly acting on the axial end face of the fixed shaft. The cable is guided through the lead hole to reduce the compression of the cable.
Benefits of technology
This effectively avoids cable bending damage, improves disassembly efficiency, and reduces maintenance workload.

Abstract
This utility model relates to the technical field of bearing disassembly and assembly auxiliary tools, and provides a bearing disassembly auxiliary tool suitable for disassembling bearings of external rotor motors using a puller. The bearing disassembly auxiliary tool includes a support block and a limiting member. The support block includes a first end, a second end, a peripheral sidewall, and a lead wire hole. The first end is located on the side opposite to the fixed shaft and is used to support the puller's push rod. The second end abuts against the axial end face of the fixed shaft. The peripheral sidewall connects the first end and the second end. The lead wire hole connects the second end and the peripheral sidewall, and the cable is inserted into the lead wire hole and can extend from the peripheral sidewall. The limiting member is installed on the second end, forming a slot with the second end. The end of the fixed shaft is inserted into the slot, and the limiting member is located on the periphery of the fixed shaft. This avoids the push rod directly acting on the axial end face of the fixed shaft, preventing excessive compression of the cable located at that position, which could lead to cable bending and damage.
