Coupling device for a robot joint and robot with such a coupling device

摘要

The invention relates to a coupling device (1) for a robot joint with a first and second robot arm segment (2, 3), comprising a rotor (4) which is designed to be connected to the first robot arm segment (2) in a rotationally fixed manner, a stator ( 5), which is configured to be non-rotatably connected to the second robot arm segment (3), as well as at least one first working chamber (6) which is configured between the rotor (4) and the stator (5) and is configured to have a hydraulic fluid to be operated in order to set a torque and to rotate the first robot arm segment (2) relative to the second robot arm segment (3) in a first direction of rotation. The invention also relates to a robot comprising a robot joint with a first and second robot arm segment (2, 3) and a coupling device (1) according to the invention.
