Abstract
A rotary drive device has a fluid-actuated rotary drive, which has a drive housing and a drive unit rotatable relative thereto. The drive unit has a pivot piston and a drive shaft connected thereto, whereby the drive shaft projects from the drive housing on an axial front side with a drive section. On the rear side, several components are mounted in axial succession on the drive housing of the rotary drive, which together with the rotary drive form a uniformly practicable drive assembly. These components include a valve carrier device carrying a control valve arrangement, a pneumatic connection unit, and an electronic control unit electrically connected to the control valve arrangement. A robot arm is also proposed, which includes the rotary drive device as an arm joint.
