Roots Fans在使用的过程中轴承出现了问题，那么轴承出现了损坏的原因是什么呢？关于这个问题罗茨风机小编带你了解一下。
1、轴承装配不当，如冷装时不均匀敲击轴承内圈使轴受到磨损，导致 轴承内圈与外圈配合失去过盈量或过盈量变小，出现跑内圈现象，装电机端盖时不均匀敲击， 导致端盖轴承室与轴外圈配合过松出现跑外圈现象。无论跑内圈还是跑跑外圈均会引起轴承 运行温升急剧上升，只要轴承完好，允许间断性跑外圈现象存在。
2, bearing bearing wall is not clean, or add grease is not clean. For example, bearings to keep tiny steel material for thorough cleaning, running is bearing roll to damage caused by high temperature rise burned bearings.
3, bearing re-exchange processing, motor end cover nesting after the excess surplus or oval degree exceeds the standard caused by bearing ball clearance is too small or uneven resulting in bearing operation friction increases, the temperature rises sharply until burned.
4, due to the stator, rotor core axial misalignment or re-axis machining accuracy is not enough, resulting in the bearing inner and outer ring is not in a cut surface caused by the bearing operation “to eat other strength” after the temperature rises until burned.
5. Bearing damage due to mixing of different types of grease.
6、轴承本 身存在质量问题，例如滚道锈斑、转动不灵活、游隙过小、保持架变形等。
7, the spare machine does not run for a long time, grease deterioration, bearing rust and the only maintenance and maintenance can only be used to pay attention to the regular inspection and regular replacement of the same brand of grease.
