Abstract:
1. A slip coupling, comprising: a pair of coupling elements rotatable about a common axis of rotation, each said coupling element having a coupling surface annularly circumferential about the axis of rotation, one of the two coupling elements having a threaded journal disposed in line with the axis of rotation; a clamping nut screwed onto the threaded journal and configured to press the coupling surface of the other one of the coupling elements against the coupling surface of the one of the coupling elements so that a torque acting on one of the two coupling elements is transmitted in a slip-free manner to the other one of the coupling elements up to a holding torque and limited to a sliding torque as the coupling elements slip against one another; a number of free play disks disposed between the clamping nut and the other one of the coupling elements; driver elements interacting with one another and received by the clamping nut, the free play disks and the other one of the coupling element, said driver elements enabling the coupling elements to slip against one another up to a critical angle without rotation of the clamping nut, and in the presence of a slippage of the coupling elements against one another beyond the critical angle, causing a co-rotation of the clamping nut with the driver elements, wherein the co-rotation of the clamping nut causes a change of a contact pressure of the coupling surface of the other one of the coupling elements on the coupling surface of the one of the coupling elements and thereby causes a change of a holding torque transmittable in a slip-free manner.
