Abstract:
A safety coupling comprising two coupling disks (17, 18) having a common axis wherein at least one of which has a coupling track (25) periodically varying in height, on which rollers (23) each having a single axis of rotation are provided between the coupling disks perform a rolling movement, a housing (12) surrounding the coupling disks (17, 18) and a spring device (21) supported on the housing (12) and pressing the coupling disks (17, 18) against each other, characterized in that the coupling track (25) is a path described by a reference body (29) having the same form, size and single axis of rotation as the rollers (23) and being radially aligned with the common axis of said coupling disks (17, 18), whereby the reference body (29) performs a periodical axial movement relative to the coupling disk during a uniform rotation of said coupling disk (18).
