The wide variety of couplings is divided into the following:
1. Rigid coupling (without compensation capability)
2. Flexible coupling (with compensation capability), flange coupling, cross slide coupling, slide coupling, universal coupling, gear coupling.The gear coupling is composed of two outer sleeves with internal teeth and flanges and two inner sleeves with external teeth.Rely on the internal and external teeth to mesh to transmit torque.The tooth profile curve of the gear is involute, and the meshing angle is 20°.This type of coupling can transmit a large torque and allow a large offset. The installation accuracy is not high, and it is often used in heavy machinery.
3. Flexible couplings with elastic elements, roller chain couplings, elastic sleeve pin couplings, elastic pin couplings, star couplings, plum blossom couplings, tire couplings , Diaphragm coupling.The structure of the diaphragm coupling, its elastic element is a certain number of very thin polygonal ring (or circular ring) metal diaphragms stacked together to form a diaphragm group, there are several bolt holes on the circumference of the diaphragm, Use twisted holes and bolts to connect with the half coupling at staggered intervals.In this way, the arc segment on the elastic element is divided into two parts that are staggered compressed and stretched. The stretched part transmits torque, and the compressed part tends to buckle.When there is axial, radial and angular displacement of the unit, the metal diaphragm will produce wavy deformation.
