Description

Technical Field

[0001] The invention belongs to the technical field of mechanical maintenance, and in particular relates to a device and a method for disassembling pulleys and couplings of various specifications. Background Art

[0002] The coupling in the transmission equipment is a mechanical component used to connect the driving shaft and the driven shaft in different mechanical equipment so that they rotate together to transmit torque. There are various types of couplings, mainly including: elastic element flexible couplings, rigid spur gear couplings, diaphragm elastic clutches, elastic pin couplings, synchronous pulleys and many other types of couplings. These couplings each have their own characteristics and application scenarios, and they need to be selected based on specific transmission requirements and working environments. During the equipment maintenance and replacement process, disassembly of the coupling is an essential step.

[0003] At present, a puller device is usually used to disassemble the coupling in the factory. However, due to the wide variety of sizes and types of couplings, they need to be firmly fixed for a long time before being disassembled by a puller. It is very easy for the coupling to fail to be fixed or the coupling to be unstable. At the same time, the existing disassembly technology also has the problems of low safety factor, low disassembly efficiency, and easy damage to equipment. The staff needs to have strong experience to disassemble the coupling safely, which is time-consuming and labor-intensive, and the work efficiency is obviously not up to standard.
