Coupling specifically for shaft encoders
Controlflex from Schmidt-Kupplung was designed especially for the requirements of shaft encoders. The unique design of the middle element transmits torque at constant angular velocity and accommodates all kinds of misalignment with very low restoring forces. This is essential for encoders due to their small and sensitive bearings. The misalignment is compensated in-plane in a remarkably small envelope.
The coupling is offered in four series to meet different application requirements. The series Standard is the choice for all standard encoders and tachos, featuring a balanced design of precision with very low restoring forces to meet exactly the requirements of today's encoders. It is available with outer diameters ranging from 19mm to 37mm and offers a maximum radial misalignment capacity depending on size up to 1mm, a maximum angular misalignment capacity up to 1.5deg.
The anodised clamp hubs are balanced for high speed applications up to 25,000rpm. A modular construction guarantees all bore combinations ranging from 3mm up to 20mm from stock. The Impuls Plus series is designed for encoders with maximum accuracy. It is designed for encoders using a graduated disk with increased line counts or with fine measuring signals.
For applications where the coupling has to be integrated into a very tight axial space - for example where the coupling has to be mounted in a fixed housing - the Compact series is ideal. And completing the line up is the series Industry, which provides an increased range of outer and bore diameters specially for robust industrial encoders with larger shaft dimensions.
