CouplingIt is an intermediate part that connects the motor and the bearing or two shafts of general mechanical equipment. The coupling has high torque rigidity, zero rotation clearance, and elastic body compensation for the radial, axial and angular directions generated by the two shafts in the transmission process of the manufacturing machinery. The characteristics of deviation, clockwise and counterclockwise rotation characteristics are equal, the diameter of the shaft and the coupling are the same.
The two shafts cannot be separated when the machine is running. The two shafts can only be separated after the machine is stopped and the connection is disconnected.
Due to manufacturing and installation errors, deformation after load, and the influence of temperature changes on the two shafts connected by the coupling, the relative position of the two shafts will change, 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 it can maintain the connection function and the purpose of the coupling under the condition of relative displacement, the coupling can be divided into rigid couplings, Flexible coupling and safety coupling.
