ABSTRACT:
In an outer shell of a pump impeller of a hydrodynamic torque converter, an axial connecting branch of a hub is joined by friction welding to a bearing sleeve, which exhibits axial driving teeth for driving a recirculating positive-displacement pump. The friction welding apparatus uses a respective receiving fixture for holding the joint parts and a device for machining a weld bead with a tool.
