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. Typical applications are: Servo or stepper motors for linear axes, industrial robots, test benches, etc. 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 harsh conditions. Typical applications are: Conveyor systems, pumps and agitators, packaging machines, etc. Two coupling types are available for each of the application classes described above. Bellows couplings and beam couplings Elastomer jaw couplings and oldham couplings Bellows couplings offer high torsional stiffness. This makes them excellent for precise and controlled movements. Beam couplings have lower torsional stiffness compared with bellows couplings, but they can compensate for higher shaft misalignments. Elastomer jaw couplings are designed for high torque transmission and can be used in all manner of applications. Oldham couplings transmit less torque but can compen- sate for higher shaft misalignments.
