Exciter apparatus and method for rotating chain or track bushings by combining static and dynamic torque.

摘要

Method and apparatus for rotating the bushings (26) encircling the pins (38) of the pivoted interconnections of track links (34,46), such as employed in crawler tracks or in conveyor chains, in order to ensure regular wear of all parts of said bushings in contact with a sprocket.
The improvement involves vibrating the links relatively to one another by means of an exciter (68) acting between members (48,52) secured to respective ones of the links while applying a rotational force to the bushing by means (18).
