ABSTRACT:
The centering unit for the primary and secondary flywheels of a torsional vibration damping apparatus for use in the power train of a motor vehicle employs a radial bearing with a sleeve which is or can be a press fit on or in one of the flywheels, and the still accessible internal or external surface of the sleeve is calibrated simultaneously with or following the press fit. The calibrated surface of the sleeve is thereupon inserted into a socket or receives an extension of the other flywheel. The centering unit further utilizes an axial bearing wherein the function of the sleeve in the radial bearing is performed by an annular collar which can extend radially inwardly or radially outwardly of the sleeve. One of the bearings can be installed radially inwardly of the fasteners which secure the primary flywheel to the output shaft of the engine, and the other bearing can be installed radially outwardly of such fasteners.
