Abstract:
1. A torque limiter comprising: an outer sleeve whose inner wall possesses at least one peripheral groove and a plurality of recesses each recess runs parallel to a longitudinal axis of the outer sleeve; an elastic ring inserted into each groove; a rolling-element cage received within the outer sleeve and which possesses a plurality of slots corresponding to the number of recesses; a number of rolling elements that are inserted into the rolling-element slots, each rolling element in contact with the elastic ring mounted in the outer sleeve, an inner sleeve received within the rolling-element cage and whose external wall possesses a number of V-shaped notches each running parallel to the longitudinal axis, the number the same as the number of rolling-element slots, and a tool which restricts the relative torsion between the rolling-element cage and the outer sleeve between a first received position when the outer sleeve is turned in the rotational direction whereupon the tool transfers the torque and the rolling elements align with the recesses and enter the inner sleeve from the notches under radial pressure from the elastic ring having attained the maximum torque of transfer—and a second received position—when the outer sleeve is loosened by rotation and the rolling elements which move into the notches on the inner sleeve changing position vis-à-vis the recesses on the outer sleeve.
