Mechanical Friction Torque Limiter Mechanisms with Couplings

Operation

• Continuously engaged friction torque limiter slips when the torque setting is exceeded. Continues to slip until the overload ceases.
• Each half of the assembly, (1) torque limiter mechanism and (2) the coupling/sleeve assembly, is attached to a fully supported shaft.
• The tabs on the outside of the friction discs in the mechanism slide into the slots in the coupling/sleeve assembly, creating a connection for the transfer of rotary motion from one shaft to the other.

IMPORTANT: If precise alignment of the two shafts cannot be obtained, consider a flexible torque coupling model.

Application

• 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 is required after torque limiter slips.
• The slip torque setting can be adjusted.
• Both the torque limiter mechanism and coupling/sleeve assembly are bored and keyed to fit any shaft size up to the maximum shown (US & Metric).
