Mechanical Friction Torque Limiter – Through Shaft
MECHANICAL FRICTION TORQUE LIMITERS
Mach III friction torque limiters, also known as slip clutches, are designed to transmit a fixed amount of torque from one machine component to another until an overload is experienced. A torque setting is established by compressing the adjustment nut to the desired torque output, then fixing it in place with the provided set screw(s). This can be set and adjusted in the field, or pre-set at Mach III before shipment. When the unit experiences torque in excess of the set value, the friction torque limiter slips until the overload ceases.
IMPORTANT: Mach III friction torque limiters do not disengage upon overload. A means of sensing and stopping the overload condition must be in place or a friction torque limiter will continue to slip, eventually overheating to the point where it is unfit for continued use.
MECHANICAL FRICTION TORQUE LIMITER – THROUGH SHAFT
Continuously Engaged, Momentary Overload Protection
Function: Overload Protection
Drive Arrangement: Shaft to Pilot Mounted Component or Pilot Mounted Component to Shaft
- Torque limiter is through bored and keyed for connection to a shaft in any axial location.
- A sprocket, pulley or v-belt sheave can be mounted on the torque limiter pilot.
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
Torque limiters can be mounted Through/Mid Shaft or End of Shaft.
Torque limiter slides on shaft and is fixed with set screws and a customer supplied key.
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.
Torque limiters are bored to suit up to the maximum shown (US & Metric) for easy installation.
Machined pilot for easy mounting of pulley or sprocket.
