A rotation shaft machine with a wedge coupling between a drive shaft and an eccentric device for the shaft movement, with which the wedge is mounted in a radially extending recess of an eccentric disc and in two coupling positions which lie diametrically opposite to one another according to a pattern is couplable in and decouplable from an axially extending groove of the drive shaft. The wedge has a groove which is open in the axial direction and at each coupling position there is arranged a switching rod, which is controllable according to the pattern, with a coupling member, the coupling member crossing into the groove of the wedge. |
