Couplings can be divided into rigid couplings, flexible couplings and safety couplings.The main types and characteristics of the coupling and the lack of other functions in operation include flange couplings, sleeve couplings, clamp couplings, etc. Rigid couplings can only be used for transmission in the role of the type transmission system Movement and torque.
The principle of the elastic coupling: a device that mainly transmits the torque produced by the prime mover to the driven mover.The old-fashioned Oldham slider coupling can compensate for manufacturing errors, device errors, and deformation after loading between the prime mover and the driven mover.The axial, radial and angular deviation caused by the protrusion of the intermediate coupling and the temperature change.Utilize the elasticity of the diaphragm (or elastomer).The two half couplings are respectively fixedly mounted on the driving shaft and the driven shaft.Change one side of the middle cross slider from a convex shoulder to a groove, and the doors are respectively installed in the grooves of the two half couplings.The Oldham coupling has been improved.At the same time, it will be assembled with it so that the function of the coupling will be greatly changed.When the half of the coupling that is changed to a shoulder undergoes a large angular displacement, the groove of the coupling is changed to a shoulder.As long as its shoulder does not depart from the groove of the intermediate coupling, and the shoulder of the intermediate coupling does not detach, the coupling can still be used normally, and the other half is the groove of the coupling.Greatly increase the allowable angular displacement and the comprehensive displacement produced by the radial displacement of the coupling.When the coupling is working, it can prevent the corners of the inner and outer teeth from contacting, and the compensation performance is good.
