ROCKSHAFT LINER WITH THRUST SURFACE

摘要

A bearing block assembly includes a liner having a two piece ring of low friction material extending around the rockshaft and held in place by a bearing block. The rockshaft includes a radially projecting member interacting with the bearing block assembly to maintain the axial position of the rockshaft. The bearing liner includes a flange extending beyond the bearing block to contact the projecting member. The flange is seated in a groove at the side of the bearing block and lowers the coeffiecient of friction at the rockshaft/thrust surface interface.
