引起轴承温度偏高的主要原因有以下几点:

(1)润滑质量不良。润滑的目的,是使消息部分不直接接触产生摩擦,而形成固体与液体之间的摩擦。假如润滑油数目不足或质量不良,会使消息部分直接摩擦发热,或热量不能通过润滑油带走,而使轴承温度升高。

(2)转动轴承装配质量不良。如内套与轴的紧力不够,外套与轴承座间隙过大或过小。

(3)轴承质量不良。滑动轴承刮研质量不良,乌金接触不好或脱胎;转动轴承转动体面有裂纹、碎裂、剥落等,都会破坏油膜的稳定性与均匀性,面使轴承发热。

(4)密封毛毡过紧而发热。

(5)轴承振动过大而承受冲击负载,严重影响润滑油膜的稳定性。

(6)轴承冷却水量不足或中断,影响热量的带出,而使轴承温度升高。

以上答案仅供参考。
