Drive and/or adjustment device having overload protection

A drive and/or adjustment device for driving and/or adjusting a rotatable assembly comprising a large rolling bearing ring of a wind turbine or a slewing gear of a construction machine or of a hoist, comprising an output element for rotationally driving and/or adjusting the rotatable assembly, a transmission which is connected downstream of the output element and has at least one torque-transmitting gear, and an overload safety mechanism for the rotatable assembly, wherein the overload safety mechanism is on the at least one torque-transmitting gear, wherein the gear is divided and comprises two gear parts that are torque-transmittingly interconnected via spur toothing and held axially in spur toothing engagement by an axial securing means which yields at a predetermined axial loading between the gear parts, wherein the axial securing means comprises one or more tension and/or screw bolts which is/are seated in axial recesses in both gear parts and clamp/clamps the gear parts against one another on an end face, wherein the tension and/or screw bolts extend through the spur toothing, wherein the one or more tension and/or screw bolts are parallel to an axis of rotation of the at least one torque-transmitting gear and are spaced from the axis of rotation.
