Reasons for damage to Roots fan bearings
Roots Fans在使用的過程中軸承出現了問題，那么軸承出現了損壞的原因是什么呢？關于這個問題羅茨風機小編帶你了解一下。
1、軸承裝配不當，如冷裝時不均勻敲擊軸承內圈使軸受到磨損，導致 軸承內圈與外圈配合失去過盈量或過盈量變小，出現跑內圈現象，裝電機端蓋時不均勻敲擊， 導致端蓋軸承室與軸外圈配合過松出現跑外圈現象。無論跑內圈還是跑跑外圈均會引起軸承 運行溫升急劇上升，只要軸承完好，允許間斷性跑外圈現象存在。
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、軸承本 身存在質量問題，例如滾道銹斑、轉動不靈活、游隙過小、保持架變形等。
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.
