Coupling shaft (1) for transmitting a torque from the power take-off shaft of a tractor to the input shaft of a driven agricultural machine, which shaft is provided with at least one universal joint (2), wherein the shaft (1) is protected by a tube (3) of fitting material which is mounted on the shaft (1) by means of a bearing ring (10) which protrudes into a groove (11) of the shaft (1) and is connected to a cover (4) which is fixed to the tube (3) and which projects over the universal joint (2), wherein the bearing ring (10) is provided with at least two cam-like protrusions (13) arranged along the periphery of the ring (10) at a mutual distance and the cover (4) is provided with at least two spaces (15) in each case for receiving these protrusions (13), wherein by an angular displacement of the bearing ring (10) relative to the cover (4) a locking in axial sense is effected between cover (4) and bearing ring (10), and wherein an insert piece (20) is active between cover (4) and bearing ring (10) to counter an opposite rotation of this bearing ring (10) such that assembly can take place without tools, but disassembly takes place with tools. <IMAGE> |
