Abstract

A blocking device, and a gear-drive unit containing such a blocking device, and a method for producing such a gear-drive unit for blocking a rotary motion of a shaft relative to a housing of the gear-drive unit, having a first, rotatable blocking element and a second blocking element which is displaceable relative to the first blocking element by means of at least one electromagnet and at least one restoring element, in which the blocking elements in the blocked state mesh in the axial direction with one another by form-locking, and the blocking device is embodied as a separate, independent structural unit, which can be mounted as a unit on the one hand onto the housing and on the other onto the shaft.
