Description

Application as
• Overrunning Clutch
for multi-motor drives in which a drive is automatically disengaged when it is no longer supplying power.

Features
Housing Freewheels FHD with hydrodynamic roller lift-off are typically used in cases where an assembly can be driven from two or more motors or turbines at the same or similar high speed. They allow a continuous plant operation in the event that one of the energy sources or a drive line fails as well as energy saving in the case of partial load operation. For safe system maintenance, the Housing Freewheels FHD are equipped with a mechanical separation function to decouple the input drive from the output drive train.
The Housing Freewheels FHD are completely enclosed freewheels for stationary arrangement with input and output shaft.

Advantages
• Nominal torques up to 24405 Nm
• Shaft diameter up to 109,5 mm
• Wear-free operation
• Low noise
• Low power dissipation
• Integrated oil filtration system
• Mechanical separating function
• Oil change without down time
• Complies OSHA “Lockout-Tagout” requirements
