Coup-Link Shaft Coupling

Like all mechanical parts, shafts are subject to manufacturing and assembly tolerances that generally cannot be entirely eliminated even with extensive technical measures. Without compensation of these mechanical deviations, they can cause vibrations, noises and stiffness, eventually reducing the lifespan of the connected units.

The recently added couplings of aluminum and stainless steel include designs for positive and non-positive connections. Multiple bore diameters, various stiffness and hardness levels of the coupling body as well as an optional keyway allow very specific customization to the given use case. In general, all couplings compensate for offsets and misalignments, accommodate runout error and axial motion and dampen vibrations and impacts to varying degrees.

At the application level, there is a choice between position and motion control or torque and power transmission.

For position and motion control, the rotary motion must be transmitted with very high precision and accuracy. This requires a coupling type that functions with zero backlash in the direction of rotation and has high torsional stiffness. Typical applications include: Servo and stepper motors for linear axes, industrial robots and test benches.
