The protective device of the coupling is usually provided by the buyer. Therefore, this part of the content is not a requirement for the coupling. The buyer or the contractor should specify the type of protective device required. Each coupling should have a protective device for Seal the coupling and shaft to prevent the unit from running...
The elastic coupling has good axial compensation, good vibration reduction performance, radial and angular axis offset performance, simple structure, stable and reliable operation, no noise, no lubrication, simple maintenance, convenient assembly and disassembly, and good manufacturability , Low cost, long life...
The principle of coupling needs should be based on the six aspects of speed, torque, assembly and disassembly, neutrality, cost, and environment: the selection principle of coupling ((expansion sleeve))...
