Abstract

A pneumatic rotary drive includes a housing which is connectable to a pressure medium source and is closed in a pressure medium-tight manner by plane covers. A rotatable shaft extends out of the housing through at least one of the covers. A belt which is in engagement with the shaft is arranged within the housing so as to form moveable pressure chambers. At least one guide body arranged within the housing is surrounded by the belt. At least one of the guide bodies is provided with a spring element for resiliently adjusting the effective circumference of the at least one guide body.
