Abstract
A torque limiting device that includes a shaft and a wrap extending around the shaft. The wrap is frictionally engaged with the shaft, and the wrap has an inner and an outer surface. The device further includes a restraining mechanism enclosing the wrap such that there is contact between the restraining mechanism and the outer surface of the wrap, and such that the restraining mechanism prevents the wrap from rotating relative to the retraining mechanism as the shaft is rotated in either one of two opposing rotational directions.
Claims9
A torque limiting device comprising:
- a shaft having a longitudinal axis;
- a wrap extending around the shaft such that the wrap is frictionally engaged with the shaft, the wrap having an inner and an outer surface;
- and
- restraining means engaging the outer surface of the wrap at all stages of operation of the torque limiting device to prevent the wrap from rotating relative to the retraining means as the shaft is rotated about its axis.
