Torque Limiter Coupling, Servo Couplings and Industrial Couplings: A Selection Guide
The coupling between a motor and a driven shaft is one of the most functionally important components in a power transmission system and one of the most frequently under-specified. Beyond simply connecting two shafts to transmit torque, a well-selected coupling compensates for shaft misalignment, protects the system from torque overloads, and in the case of servo couplings, maintains the torsional stiffness and low backlash that precise motion control systems demand. Understanding the differences between torque limiter couplings, servo couplings, and general industrial couplings helps engineers select the right component for each application's specific requirements. What is a torque limiter coupling? A torque limiter coupling is a coupling that transmits torque normally up to a set threshold and disconnects or slips when the torque exceeds that threshold, protecting the drive train and driven machine from damage caused by torque overloads. Overloads in industrial machinery occur du...
