Spring Wrapped Slipped Clutches

Fully adjustable, intermittent-duty slip clutch assemblies are available from SDP/SI. These assemblies function as a buffer against temporary overload between a shaft and a mounted component (gear or pulley).

Our mechanical spring-wrapped (continuous) slip clutches are made to accept gears, sprockets, or pulleys. Regardless of the direction of rotation, slip torque is constant and velocity independent.  Applications for the spring-wrapped clutches include tension control of film or tape drives and transmission overload protection.

They feature:

  • Long life under continuous slip conditions
  • Unidirectional or bidirectional operation
  • Same or different clockwise and counterclockwise torques.
  • Precise and stable limit torque calibration (range: 0.007 to 4.24 N • m)
  • Same torque at breakaway as at high slip velocities
  • Corrosion-resistant materials

The slip coupling serves as a torque limiter as well as a coupling for two colinear shafts. This coupling is equipped with hubs at both ends for pinning to the (two) shafts. When the load exceeds the limit torque of a slip coupling, the two shafts rotate relative to each other at the full limit torque. The standard coupling is designed to operate with 3° angular or linear misalignments of up to 0.25 mm between the two shafts. The mounting hole diameters of the slip couplings can differ for the two ends, so that different diameters of “in-line” shafts can be coupled together.
