Joint for transmitting torques and axial forces

摘要

The invention discloses a joint (10) for transmitting torques and axial forces in conjunction with an eccentric rotational movement. In a preferred embodiment, the joint according to the invention is used in an eccentric screw pump for connecting the drive input to the pump rotor. The joint connects a coupling rod (18) and a tool (20) and/or a drive input to one another. In the case of the joint being used in an eccentric screw pump, the tool is the rotor of the pump. The joint is furthermore provided with at least one casing. The axial forces which act on the joint can be transmitted by a first joint part (12) and the torques can be transmitted by a second joint part (14).
