In order to meet different needs, people have designed many types of couplings, some of which have been standardized. According to whether the coupling contains elastic elements or not, it can be divided into:
1. Rigid coupling is divided into fixed type-high requirements for neutrality; movable type-can compensate for various deviations.
2. Elastic coupling: It can compensate various deviations and cushion vibration.
Fixed rigid couplings require good alignment of the two shafts. Common ones are: shell couplings and flange couplings.
The movable rigid coupling is movable and can compensate for the offset between the two shafts.Divided into: cross slider coupling, slider coupling, universal coupling, gear coupling, chain coupling.
Because of the elastic element, the elastic coupling can not only compensate the displacement, but also buffer and absorb vibration. It is suitable for occasions with frequent start-up and high-speed load change and frequent forward and reverse rotation.Divided into: elastic sleeve pin coupling, nylon pin coupling, plum-shaped elastic coupling, diaphragm coupling, serpentine spring coupling, safety coupling, tire coupling.
