Description

Technical Field

[0002] As the installed capacity of wind power continues to grow and the operating time of wind turbines continues to increase, there are now many old wind turbines. The main bearings of some wind turbines have external manifestations of bearing failure, such as excessive temperature rise and abnormal noise when the bearings are running during the operation of the wind turbine. It is preliminarily determined that the bearings in this situation can no longer meet the conditions for continued operation and need to be disassembled.

[0003] Every time the entire wind turbine bearing needs to be disassembled and replaced, the staff needs to hold the bearing to install it. The bearing is heavy and has oil on the surface. It is difficult, time-consuming and laborious to replace it directly by manpower. In addition, the generator set needs to use fire to disassemble and install the bearing every time the wind turbine bearing is replaced, which leads to fire hazards in the unit and has a high risk. If the bearing is disassembled and installed manually, it is easy to cause a safety accident. Therefore, in order to solve the above problems, we need to design a wind turbine bearing disassembly and assembly device. Utility Model Content
