Shaft Collars refers to a device that connects two shafts or shafts with rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive loads, playing a role of overload protection.
Shaft Collars misalignment is divided into misalignment, parallel misalignment, and comprehensive misalignment. Misalignment of the deflection angle means that the end face of the coupling has a deflection, and the axis lines of the two half couplings present an included angle, which generates an excitation force and induces a vibration response under a rotating state.
Most commonly used Shaft Collars have been standardized or normalized. Generally, it is only necessary to correctly select the type of coupling and determine the model and size of the coupling. If necessary, check and calculate the load capacity of vulnerable weak links; When the rotational speed is high, it is also necessary to check and calculate the centrifugal force on its outer edge and the deformation of the elastic element, and perform balance verification.
