ABSTRACT:
An upper portion of each power screw of a refuse compactor is covered by a protective sleeve to insulate the threads of the screw from refuse. The upper end of the sleeve is loosely retained to the ram to move longitudinally with the ram while yielding to any pivoting of the ram during its downstroke under load. The protective sleeve additionally tends to distribute lubrication along the threads of the power screw during cycling of the ram. A protective skirt mounted to the frame of the compactor insulates a lower portion of the power screw from refuse.
