Rotary joint, especially for machine housing bearing for wind power system, has brake integrated into rotary joint with brake element(s) mounted in one rotary joint part

摘要

The joint has rotary parts (2,3), especially ball races, mounted to rotate relative to each other and a brake with at least one braking element (13) that can be actuated to be pressed against one rotary part in a frictional manner. The brake is integrated into the rotary joint in that at least one brake element is mounted in one rotary joint part. The brake element can be subjected to a regulated braking torque by applying hydraulic pressure.
