Peak Shaver Safety Hub
The Riverhawk Peak Shaver is a hydraulically activated device that becomes part of a complete coupling system. It works with a flexible coupling to help protect machines from transmitting unwanted forces. The device can either be mounted on the shaft where it would replace a hub or it can be mounted between shafts as a spacer piece. Under normal operating conditions, the peak shaver transmits 100% of the shaft power from the driving shaft to the driven shaft, providing protection when one of the machines experiences a sharp spike in torque. When a spike occurs, the internal mechanism will slip relative to one another allowing the two shafts to continue their rotation. After the torque spike has passed, the device will re-grip, continuing to transmit normal torque load.
