発明の名称
(EN) BALL BEARING
(ZH) 球轴承
要約
(EN) A ball bearing equipped with an inner race, an outer race positioned to the outside of the inner race, a plurality of rolling elements interposed between the inner and outer races, and a ring-shaped holder provided with a pocket for holding the rolling elements so as to have an interval interposed therebetween in the circumferential direction and be capable of rotating around a rotational axis, wherein the holder comprises a resin composition containing polyether ether ketone, graphite and carbon fibers, the polyether ether ketone constitutes 60-80 wt%, inclusive, the graphite constitutes 10-30 wt%, inclusive, and the carbon fibers constitute 5-20 wt%, inclusive, when the resin composition overall equals 100 wt%.
(ZH) 本发明是一种球轴承,具备:内圈、设置于上述内圈的外侧的外圈、介于上述内圈与上述外圈之间的多个滚动体和具备兜部的圆环状保持器,上述兜部将上述滚动体保持成能够沿着周向隔开间隔地以旋转轴为中心旋转;上述保持器由包含聚醚醚酮、石墨和碳纤维的树脂组合物构成,在将上述树脂组合物整体设为100重量%时,以60重量%~80重量%的量包含上述聚醚醚酮,以10重量%~30重量%的量包含上述石墨,以5重量%~20重量%的量包含上述碳纤维。
