POLYMER BEARING CAGE WITH AMORPHOUS CASE. |
摘要 |
<p>A plastic part is molded of a plastic with an inner body of crystalline plastic and an outer surface layer 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 molded 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 is molded by injecting the plastic melt at a single point intermediate the ends of a single bar of the bearing cage to permit formation of the desired amorphous layer on rails connected to the ends of the bars.</p> |
