| 蠕变：所谓蠕变是指在轴承的配合面上产生间隙时，在配合面之间相对发生滑动而言。发生蠕变的配合面呈现出镜面光亮或暗面，有时也带有卡伤磨损产生。 Creep: The so-called creep refers to the relative sliding between the mating surfaces when the clearance occurs on the mating surface of the bearing. Creep occurs on the mating surface, which shows a mirror bright or dark surface, sometimes with cards and wear. 蠕变就是指我们俗称的跑外圈、跑内圈、跑内圆、跑外圆、跑内沿、跑外沿、打滑、连轴儿转等。 Creep refers to what we commonly call running outer circle, running inner circle, running inner circle, running inner circle, running inner edge, running outer edge, skidding, connecting axle and so on. 原因：过盈量不足或间隙配合，紧定套紧固不够。 Reasons: insufficient interference or gap fit, insufficient fastening of fastening sleeve. 对策： Countermeasures: ● 检查过盈量，实施止转措施（深沟球轴承、圆柱滚子圆柱孔轴承，如果四点角接触轴承、是单向轴承、超越离合器使用内外圈带键槽的） Check the interference and implement anti-rotation measures (deep groove ball bearings, cylindrical roller cylindrical hole bearings, if four-point angular contact bearings, one-way bearings, overrunning clutch with keyway inside and outside rings) ● 适当紧固紧定套。（调心球、调心滚子、带座外球面等锥孔轴承） Fixed the fixing sleeve properly. (Conical bore bearings with self-aligning ball, self-aligning roller, outer spherical surface with seat, etc.) ● 研究轴和轴承箱的精度。（轴承装在轴承箱内的组件） Research the accuracy of shaft and bearing box.
