Problems solved by technology

The present invention designs and manufactures each part of the flexible coupling according to the unit body, and each part can be assembled reliably and has independent functions, and can be disassembled and replaced conveniently independently, thus effectively solving the problem of the flexibility of the existing wind power generating set. Inconvenience and damage to the coupling due to faulty maintenance—a single part must replace the entire flexible coupling, which greatly shortens the maintenance time and saves a lot of maintenance costs. The flexible coupling has a simple structure, easy to assemble and Easy to disassemble and replace, strong practicability

Abstract

The invention discloses a flexible coupling of a wind generator set and an assembling or replacing method of the flexible coupling. The assembling or replacing method is characterized by comprising the following steps: designing and manufacturing parts by unit, assembling the parts to form five unit components, namely a brake disc component, a left flexible connecting sheet component, a middle connector component, a right flexible connecting sheet component and a generator side coupling component; carrying out dynamic balance tests and adjustments of the unit components separately so that the unit components have symmetric structures and dynamically balanced configuration; assembling the unit components to form the flexible coupling; and carrying out a dynamic balance test and an adjustment of the whole flexible coupling so that the whole flexible coupling has dynamically balanced configuration. According to the invention, the parts of the flexible coupling, which are designed and manufactured by unit, can be reliably assembled and conveniently and separately disassembled and replaced, so that the problem of inconvenience caused by breakdown maintenance of the conventional flexible coupling is effectively solved, the maintenance time is greatly shortened, a great amount of maintenance cost is saved, and the flexible coupling has high practicability.

Description

technical field [0001] The invention belongs to parts of a wind power generating set and an assembly or replacement method thereof, and relates to a flexible coupling of a wind power generating set and an assembling or replacing method thereof, and is especially suitable for coupling between a gearbox and a generator in a wind power generating set Functional flexible coupling. Background technique [0002] Wind energy is a non-polluting, green and environmentally friendly energy, and it is the clean energy with the most potential for development among renewable energy sources. In recent years, air pollution has become more and more serious, and the development of wind energy has become a national development strategy and a contribution to the development of human society. This has led to the rapid development of new energy wind power generation technology, which has attracted more and more people's attention. At present, countries around the world are paying more and more a...
