Abstract:
The present invention relates to a rotary drive (100) comprising: an output shaft (330); a motor (20), acting on the output shaft (330) via a downstream gear mechanism (30); an energy-store module with a linear line of action and with transmission elements (32, 326) to apply pressure circumferentially to an eccentric cam disk (331) arranged on the output shaft (330) for conjoint rotation therewith; and an intermediate shaft (320), being offset in relation said line of action and being provided between the motor (20) and the output shaft (330). The transmission elements (32, 326) comprise a roller lever (32), having a cam-follower roller (326) spaced apart from the intermediate shaft (320), wherein the cam-follower roller (326), pressed circumferentially against the eccentric cam disk (331), interacts with the output shaft (330). The energy-store module is arranged on the motor side in relation to the intermediate shaft (320).
