Description

Technical Field

[0001] The utility model relates to a disassembly device which can disassemble a large motor brake wheel conveniently, quickly and safely, and belongs to the technical field of motor maintenance equipment. Background Art

[0002] The motor brake wheel is installed at the end of the motor output shaft to transmit power. The manufacturing process is generally based on casting and forging. The motor brake wheel is usually installed and connected to the motor shaft through key connection or heat installation. The motor brake wheel is usually disassembled and replaced due to motor damage or cracking of the brake wheel.

[0003] At present, pullers are used to disassemble the brake wheels of general small and medium-sized motors. Pullers are commonly used maintenance tools in the machinery industry. Most pullers adopt a screw-rotating ejection structure, which has a simple structure and is easy to make and use. However, in the disassembly of the brake wheels of large motors, it is found that since the brake wheels, pulleys, couplers and other components of many large electromechanical equipment are not wearing parts and have not been disassembled for many years, they are seriously corroded and adhered, and some parts are heavy, which can reach several tons. When using a puller with a screw mechanism to disassemble, it is difficult to disassemble. The old-fashioned puller is usually made of simple cutting of iron plates, which is very bulky. It is also necessary to make a fixed frame and use two hand hoists to fix and adjust the position of the puller and the brake wheel. The brake wheel and the motor shaft have been cooperating for a long time, and there is adhesion between them. The traditional puller is usually disassembled by screwing the screw nut with a wrench, and there is no locking function, which cannot maintain a constant force to fix the brake wheel.

[0004] In particular, the clamping parts of ordinary pullers are fixed, and can only be used to remove brake wheels of one model or diameter, which has poor versatility. When there are many motor models and different brake wheel diameters, multiple special pullers are required, which greatly increases the number of maintenance tools and increases maintenance costs. If there is no suitable puller to remove the motor brake wheel, a more direct method is to use destructive disassembly such as cutting, which is very likely to cause damage to the motor, prolong maintenance time, and increase production costs.

[0005] In view of this, it is currently necessary to improve the existing puller, improve the performance and versatility of motor maintenance equipment, improve maintenance work efficiency, and reduce maintenance and production costs. Utility Model Content
