Abstract
A torque limiter has an outer sleeve whose interior wall possesses at least one peripheral groove and a plurality of recesses running parallel to the axis. An elastic ring is inserted in each groove. A rolling-element cage has the same number of slots as the number of recesses possessed by the outer sleeve that receives it. A plurality of the rolling elements that are inserted into the rolling element slots. The inner sleeve which slots into the rolling-element cage and whose exterior wall possesses the same number of V-shaped notches—running parallel to the axis—as the number of rolling element slots is provided. A tool or system is provided to restrict the relative torsion between the rolling-element cage and the outer sleeve between a first received position—and a second received position—when the outer sleeve is loosened by rotation and the rolling elements which slot into the notches on the inner sleeve change position vis-à-vis the recesses on the outer sleeve.
