摘要

Coupling device for connecting a transmission output shaft and a worm shaft of a screw machine with a base body (27), - at least one worm shaft (13, 14) defining an associated axis of rotation (8, 9), wherein the respective worm shaft (13, 14) a worm shaft stop (21, 22) which extends annularly around the axis of rotation (8, 9), - at least one coupling sleeve (29, 30) for non-rotatably connecting the respective associated worm shaft (13, 14) and a transmission output shaft ( 6, 7) in which the respective worm shaft (13, 14) about the rotational axis (8, 9) rotatably and in the direction of the axis of rotation (8, 9) is arranged displaceably, characterized in that a fixing element (34) releasably attached to the Base body (27) is fixed and a fixing element stop (48, 49) for limiting the movement of the respective worm shaft (13, 14) in the direction of the axis of rotation (8, 9) is formed, and that the fixing element (34) at least one passage opening ( 45, 46) for performing the at least one worm shaft (13, 14) and at least one transverse to the axis of rotation (8, 9) extending insertion section (47; 47a, 47b) for introducing the at least one worm shaft (13, 14) into the at least one passage opening (45, 46).
