Clamping couplingIt is composed of two halves of the simple sandwich shell divided longitudinally and the bolts connecting them.Since this kind of coupling does not need to move the shaft during assembly and disassembly, it is convenient to use.
The material of the jacket is generally cast iron, cast steel, and stainless steel.The small and medium-sized clamp shell couplings mainly rely on the friction between the clamp shell and the shaft to transmit torque. Even if the coupling is equipped with a key, the function of the key is not taken into account when calculating its load-bearing capacity. , The calculation method is similar to the clamping connection.The large-size clamp housing coupling mainly transmits torque by the key.In order to improve the balance, the bolts should be installed between the forward and reverse phases.
Jacketed couplings are mainly used for low speed, and balance inspection is required when the speed exceeds 5m/s.
