ROTATIONAL DRIVE

The invention relates to a rotational drive with a shaft (40), which is fixedly supported relative to a base element (10), comprising an annular engaging element (51) with an engaging disk (53) mounted therein, which has an engaging disk outer wall that corresponds to and can be engaged in an engaging element inner wall, both constituting a drive plane (x, y), and with at least two electromechanical actuators (31) the effective direction of which extends in the drive plane (x, y), with one respective movement component parallel to the drive plane (x, y) and a respective orthogonal component in relation to the movement component, wherein a movement region of the actuators (31) is limited by the interaction of the engaging element (51) and the engaging disk (53). Advantageously, the drive is characterized in that a drive plate (23) is displaceably mounted in a plane parallel to the drive plane (x, y) and can be adjusted parallel to the drive plane (x, y) and relative to the base element (10) by the movement components of the actuators (31). Furthermore, the drive is characterized in that the shaft (40), which is arranged at a distance from the stationary support (14), is connected in a coaxial and a rotationally fixed manner to the engaging disk (53) and is mounted without play, but rotatable, in a drive plate support (24) in the drive plate (23).
