发明名称 Cage production
摘要 A method for the production of a cage made of castable or injection moldable polymeric material for rolling elements of a rolling contact bearing whereby the cage has pockets for receiving the rolling elements and contains a porous lubricant carrier, and the pockets have perforated walls to provide a direct contact between the lubricant carrier and the rolling elements. The cage is made in an injection mold or casting mold provided with cores for forming the pockets, characterized in initially inserting the lubricant carrier (5,24) into the mold (1,19), then closing the mold (1,19) whereby the lubricant carrier is elastically deformed by the cores (12,35,36) and finally surrounding the lubricant carrier (5,24) with polymeric material except at its supporting surface (14,38) and its surfaces engaging the cores (12, 35, 36).
