Parts carrier assembly for grinding machine

摘要

A parts carrier assembly for a grinding machine includes an annular parts carrier and a bearing insert. The annular parts carrier includes an upper surface, a lower surface, an inner edge, an outer edge, and a plurality of loading apertures. The inner edge is configured to engage a driving wheel of the grinding machine. The driving wheel rotates about a central axis resulting in rotation of the parts carrier about an offset axis, which is offset from the central axis. The loading apertures are configured to receive parts to be ground by the grinding machine. The bearing insert includes an inner bearing surface complementary in shape to the outer edge of the parts carrier. The outer surface the parts carrier bears against the inner bearing surface of the bearing insert as the parts carrier rotates about the offset axis.

1. A parts carrier assembly for a grinding machine, the parts carrier assembly comprising:
an annular parts carrier including an upper surface, a lower surface, an inner edge, an outer edge and a plurality of loading apertures extending through the parts carrier from the upper surface to the lower surface, wherein the inner edge is configured to engage a driving wheel of the grinding machine rotating about a central axis resulting in rotation of the parts carrier about an offset axis, which is offset from the central axis, wherein the loading apertures are configured to receive associated parts to be ground by the grinding machine; and a bearing insert having an inner bearing surface complementary in shape to the outer edge of the parts carrier, wherein the outer surface of the parts carrier bears against the inner bearing surface of the bearing insert as the parts carrier rotates about the offset axis, wherein the bearing insert is substantially crescent shaped when viewed normal to the central axis.
