ABSTRACT:
An assembly machine and method for assembling an integral bearing unit onto a motor vehicle wheel hub. The assembly process involves applying an axial force onto the elements causing the elements to be pressed together. In order to avoid localized brinelling of the surfaces of the bearing including the faces and rolling elements, the hub is rotated during the pressing operation to cause the forces to be spread over areas of the rolling elements and bearing races. The machine and method further incorporate a sensor to detect improper position or installation of the bearing on the assembly tooling and a load cell to monitor pressing loads enabling detection of improper part fit or other defects.
