Fabrication of bearing involves sintering ceramic material at high temperature, adding the sintered ceramic material into heat-resisting plastic-steel material to form uniform mixture, which is then molded to the bearing by pressing

摘要

Bearing (7) is fabricated by obtaining a ceramic material; sintering the ceramic material at high temperature; adding the sintered ceramic material into heat-resisting plastic-steel material to form a uniform mixture; and molding the mixture to the bearing by pressing. An independent claim is also included for a bearing comprising an absorbent body (71) made by heat-resisting plastic-steel material or metal; a hard-wear portion (72) enveloped in the absorbent body and made by ceramic material; and a hole (73) passing through the absorbent body and the hardwear portion to receive an axis or a driving shaft transmitted by the axis. When the axis or the driving shaft operate, the absorbent body absorbs a vibration occurred under a high-speed transmission from the axis or the driving shaft, and the ceramic material of the hard-wearing increases the usage of the bearing.
