High-damping couplings

Our newly developed laminated rubber element achieves high damping and low reaction force. STEPFLEX couplings for servo stepping motors that boast high damping performance. Their unitized construction with HNBR in the power-transmitting elements provides a backlash-free design. They dampen vibration faster than flexible couplings that use metal in their elastic components. This suppresses the resonance phenomenon that can occur with stepping motors, enabling resonance to be avoided over a wide range of operating speeds.. It also provides stable high-speed control. Using a laminated rubber element that is sandwiched by HNBR layers of different hardnesses also achieves a reduction in counter force generated by misalignment. This can greatly reduce the load on the partner shaft and bearing.
