Abstract
An improved belt tracking adjustment mechanism for a belt type abrading or other machine having a frame, a drive pulley, an idler pulley and an endless belt trained over the pulleys includes a support member which supports the idler pulley for rotation about an axis fixed relative to the support member. The support member is itself attached to the frame by a single screw which as a first function supports the member for pivotal movement relative to the frame about the screw axis, which extends parallel to the idler pulley axis, to vary the spacing between the idler and drive pulley axes. A spring biases the member in the belt tightening direction and the moments imposed on the member by the belt and spring hold one edge of the member against a flat face of the frame to form another hinge or pivot axis between the frame and member. A second function of the screw is to provide adjustment of the position of the member about this hinge axis to achieve proper tracking of the belt over the pulleys.
