| titleOfInvention |
Polymer bearing cage with amorphous case |
| abstract |
A plastic part is molded of a plastic with an inner body (44) of crystalline plastic and an outer surface layer (46) of an amorphous plastic. The amorphous surface layer withstands friction loading at least during an initial break-in period. In one embodiment, the amorphous surface is formed by using a higher plastic melt temperature and/or a lower mold temperature than normal. In another embodiment, an intermediate part is moled as a crystalline intermediate part, and a surface layer is heated and quenched to form the amorphous surface layer on the final part. A bearing cage (28) is molded by injecting the plastic melt at a single point intermediate the ends of a single bar (34) of the bearing cage to permit formation of the desired amorphous layer on rails (30, 32) connected to the ends of the bars. |
