Couplings General notes Introduction Couplings create connections between drive shafts and driven shafts in order to transmit rotary motion and torque. For example, they are used to combine the shafts of motors and transmissions into a single drive unit. Alongside the primary purpose of transmitting torque, couplings also carry out other important tasks: -- Compensating for shaft offsets and misalignments -- Absorbing runout errors and axial motions -- Damping vibrations and shocks Couplings are used in a very wide range of applications. The spectrum ranges from simple drives to complex...

Couplings General notes Areas of application - Classes - Coupling types The applications of couplings can generally be divided into two classes. Motion control Torque and power transmission For motion control applications, the rotational movement is transmitted with very high precision and accuracy. This requires a coupling type with a high torsional stiffness and zero backlash in the direction of rotation. For torque and power transmission, the focus lies on pure transmission of force. This requires couplings that can withstand high torques and heavy loads while functioning reliably in...
