METHOD AND APPARATUS FOR DAMPENING BRAKE LATHE VIBRATION

摘要

A brake lathe includes a lathe body, an arbor shaft, with a free distal end, mounting means for mounting a workpiece on the shaft, motor means for rotating the shaft and workpiece, inertia means for providing inertia about an arbor shaft axis and a linking means for linking the inertia means to the arbor shaft. In a preferred embodiment, the inertial means includes a toroidal ring having mass and an inner cylindrical surface and the rotational linking means comprises a locking nut adapted for a threaded engagement with a portion of the arbor shaft adjacent the distal end and including a cylindrical outer surface and an elastic walled tube filled with a damping material interposed between the inner cylindrical surface of the toroidal ring and the outer cylindrical surface of the locking nut.
