Abstract
A balancing station includes a vertical spindle having a collet for frictionally engaging the center hole of a wheel. A motor driven drum is mounted on an arm which is moved by an actuator to urge the drum against the wheel with a radial force so that it can frictionally drive the wheel. An idler drum or a second driven drum mounted on a similar arm on the opposite side of the wheel is moved by an actuator to engage the wheel at a location diametrically opposite the driven drum to apply a radial force to the wheel equal and opposite to the force from the driven drum. The arms are symmetrically mounted with respect to the spindle so that the two drums will contact diametrically opposite locations on the wheel for any size wheel over a large size range.
