Zero-Max ServoClass-HSN Couplings Dampen Noise and Vibrations

Sept. 17, 2024
The ServoClass-HSN couplings combine an increased damping coefficient with Zero-Max's ServoClass clamping hub design for a high level of noise and vibration mitigation.

The Zero-Max ServoClass-HSN Couplings are designed to help dampen noise and vibration issues that can occur in high gain, high speed stepper/servo motor applications.

Key features of the couplings include:

  • field-proven ServoClass clamping hub system
  • high misalignment capacity
  • electrical isolation
  • composed of aluminum alloy for durability.

Designed for High Noise and Vibration Damping Capabilities

Zero-Max's ServoClass-HSN Coupling are equipped with a Highly Saturated Nitrile Rubber (HSN/HNBR) flex element to provide maximum damping performance. It plays a key role in  the coupling’s ability to provide repeatable, precise positioning and damping. 

Reducing noise and vibrations is important to many machine designs to help prevent potential damage to a system, faster wear of components and a less than ideal operator experience.

The couplings incorporate the company's field-proven ServoClass clamping hub system in which the hubs are made from aluminum alloy for strength and durability, ensuring optimal noise and vibration dampening. This clamping hub is combined with an increased damping coefficient of the engineered flex element to provide a high level of damping/anti-vibration.

A zero-backlash design provides optimal torsional stiffness for low hysteresis and repeatable, accurate positioning for those applications requiring increased damping properties. 

Additional features offered by the couplings include: 

  • low inertia
  • low reaction loads under misalignment
  • RoHS compliant corrosion-resistant fasteners  
  • fast and easy installation

The ServoClass-HSN couplings are suited for applications with a high gain, high speed response frequency and lower torsional stiffness of the driven components. A wide range of use cases are possible with the couplings, such as high-speed linear actuators, high response gantry systems, pick-and-place systems, and semiconductor manufacturing equipment.
