Flexible Mechanical Friction Torque Coupling


Continuously Engaged, Momentary Overload Protection

Operation
  • Mechanically adjustable, continuously engaged friction torque limiter slips in the event of an overload
  • Torque at which limiter will slip is field adjustable through the tightening or loosening of a nut
  • Adjustment nut is locked in place by set screws when desired torque setting is established
Mounting
  • Set screws and customer supplied key connect the torque limiter mechanism to one shaft and the coupling hub to a second fully supported shaft
  • Note: Torque Limiter Mechanism DOES NOT support Coupling
Applications
  • Momentary overload protection
  • Torque limiters are not recommended in continuous slip or tension control applications. A SensiFlex® clutch or brake should be used instead.
  • Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.
Design Features
  • No reset required after torque limiter slips
  • Elastomeric element compensates for up to 3 degrees of angular misalignment and up to 0.040 parallel offset between shafts
  • Both torque limiter mechanism and coupling bored to suit up to the maximum shown (US & Metric) to accept differing shaft sizes
