The main structure of JSD type single flange serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and serpentine spring sheets.It transfers torque by embedding the serpentine spring into the tooth grooves of the two coupling halves, and the coupling uses serpentine springs to be embedded in the tooth grooves of the two coupling halves to realize the link between the driving shaft and the driven shaft.
JSD type single flange serpentine spring coupling has the performance of compensating the relative displacement of the two shafts, compact structure, light weight, high reliability, convenient installation, and easy to arrange the mechanism on the crane trolley.
JSD type single flange serpentine spring coupling connects the two shafts due to manufacturing errors, assembly errors, installation errors, shaft load and deformation, base deformation, bearing wear, temperature changes, relative movement between components, etc. A variety of factors cause relative displacement.
Under normal circumstances, the relative displacement of the two shafts is unavoidable, but the direction of the equilibrium displacement generated by the shafting transmission under different working conditions, that is, the axial, radial angular direction and the magnitude of the displacement are different.Only the flexible coupling has the performance of compensating the relative displacement of the two shafts. Therefore, a large number of flexible couplings are selected in practical applications.
The two shafts connected by the serpentine spring coupling will cause changes in the relative positions of the two shafts due to manufacturing and installation errors, deformation after load, and temperature changes, and strict alignment is often not guaranteed.According to whether the coupling has elastic elements, whether it has the ability to compensate various relative displacements, that is, whether the coupling function can be maintained under the premise of relative displacement, and the purpose of the coupling, couplings can be divided into rigid couplings, Flexible coupling and safety coupling.The main types and characteristics of the coupling and the remarks on the role of the type in the transmission system.
