Abstract
A return stop limiting torque, particularly for conveyer systems, including an internal ring, a concentric external ring, and several retaining elements arranged in the annual gap between the rings, which allow a relative rotation between the rings in one direction, and block it in the other direction through form-fitting or frictional engagement. The external ring has friction areas at its radially extending faces, which can axially be clamped against the corresponding friction disks, with the friction disks being supported in a torque-proof fashion but at least partially axially displaceable. Here the external ring is divided into several axially adjacent partial rings, each being axially spaced from one another by an annular gap such that another friction disk is arranged respectively in this annular gap, which is supported in a torque-proof fashion but axially displaceable, and all of the partial rings and friction disks are axially clamped to each other.
