Flexible Mechanical Friction Torque Limiter Coupling

Operation

• Continuously engaged friction torque limiter slips when the torque setting is exceeded. Continues to slip until the overload ceases.
• Each side of the assembly, (1) the torque limiter mechanism and the (2) coupling, is attached to a fully supported shaft creating a connection for the transfer of rotary motion from one shaft to the other.

Applications

• Momentary overload protection.
• Torque limiters are not recommended in continuous slip or tension control applications. Consider a SensiFlex® tension control clutch or brake.
• 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.
• The slip torque setting can be adjusted.
• Elastomeric element compensates for up to 3 degrees of angular misalignment and up to 0.040 parallel offset between shafts.
• Each side of the assembly is bored and keyed to fit any shaft size up to the maximum shown (US and Metric).

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
• Both shafts must be bearing supported
