Machine for forming cylindrical bales of crop.

摘要

A roll (26) for supporting belts (24) defining the baling chamber of a machine for forming large cylindrical bales of crop is mounted by bearings (36) on an axial hexagonal shaft (34). In order to protect each bearing (36) against ingress of foreign material, e.g. stray crop and dirt, an annular deflector (38) is provided on the outward vulnerable side of the bearing (36). This deflector (38) is made of plastics material. It is mounted on the shaft (34) and has a clearance of only about 0.2 mm from the inner face of the roll (26). The deflector (38) has a pair of side-by-side grooves (40) at its periphery opening toward the roll (26). Foreign material tends, in due course, to accumulate in these grooves (40) and then to act in a self-sealing manner against further ingress.
