Controlflex Couplings for Encoders
Controlflex couplings are a zero-backlash design comprised of two aluminum hubs mated by one or two center inserts allowing for a highly customizable coupling that can match the performance requirements of most encoder systems. Controlflex couplings are lightweight, have low inertia, and have a balanced design for reduced vibration at speeds up to 25,000 RPM. They can have a wide range of bore sizes in a given outer diameter with ratios of large to small bore over 3:1, which is particularly useful in encoders where the motor shaft can be more than twice the size than that of the encoder. The inserts are designed to concentrate forces onto their flexible limbs to reduce bearing loads on sensitive bearings such as those found in encoders. Single and double insert styles are available allowing the designer to select the length and performance characteristics that best meet system requirements. Controlflex couplings are manufactured by Schmidt Kupplung in Wolfenbüttel, Germany and are widely stocked by Ruland for worldwide fulfillment. Bore sizes range from 1/8” to 1-1/2” or 3mm to 40mm.
