This locking device is a device for connecting two rotary shaft parts, in particular, a connecting sleeve of a swivel shaft that connects an agricultural trailer or a working machine to a power take-off shaft of a tractor. a number of locking bodies which are guided radially (two) in a number of openings in the peripheral wall of the cylinder, and one axially surrounding the locking bodies which in the locked position engage ten ring grooves of the power take-off shaft. It consists of a closing ring that can be pushed out against the force of a spring.

れを阻止される。When the connecting sleeve 1 is inserted into the connecting sleeve 1, the end face of the power take-off shaft 7 hits the support ring 6, and the supporting ring 6 is pushed into the connecting sleeve 1 from within the radial plane of the opening 8, as shown in FIG. The 1-0 closing ring 2, which is pushed back in the opposite direction (to the left) from the back-fitting side, is in contact with the outer surface of the locking body 3 by the force of the axial spring 5 and is radially inwardly pushed into this locking body 3. As the direct coupling sleeve 1 continues to be pushed and displaced on the power take-off shaft 7, exerting a component force in the direction, the support ring 6 is further pushed back inward, and the locking body 3 The ring groove 12 formed in the power take-off shaft 7 reaches the m-row position. Thus, as shown in FIG. 3, the locking body 3 is fitted into this ring groove 12 by means of a radial force component, and the closing ring 2 is moved into the locking body 3''. In this way, the coupling sleeve 1 is prevented from shifting axially on the power take-off shaft 7.

The inner side J is closed by a piece 14.As the connecting sleeve 1 is inserted into the power take-off shaft 7'', the support ring 6 is pushed to the left from the position shown in the figure by the power take-off shaft 7 and is locked. The body 3 moves to the right together with the coupling sleeve 1 and is supported on the power take-off shaft 7.
