1、潤滑質量不良。潤滑的目的，是使動靜部分不直接接觸產生摩擦，而形成固體與液體之間的摩擦。如果潤滑數量不足或質量不良，會使動靜部分直接摩擦發熱，或熱量不能通過潤滑帶走，而使空氣懸浮鼓風機軸承溫度升高。

1. Poor lubrication quality. The purpose of lubrication is to prevent direct contact between the moving and stationary parts, resulting in friction between solids and liquids. If the lubrication quantity is insufficient or the quality is poor, it will cause direct friction and heat generation between the dynamic and static parts, or the heat cannot be carried away through lubrication, resulting in an increase in the temperature of the bearings of the air suspension blower.

2、空氣懸浮鼓風機滾動軸承裝配質量不良。如內套與軸的緊力不夠，外套與軸承座間隙過大或過小。

2. The assembly quality of the rolling bearings of the air suspension blower is poor. If the tension between the inner sleeve and the shaft is insufficient, and the gap between the outer sleeve and the bearing seat is too large or too small.

3、密封毛氈過緊而發熱。

3. The sealing felt is too tight and generates heat.

4、空氣懸浮鼓風機軸承振動過大而承受沖擊負載，嚴重影響潤滑膜的穩定性。

4. The bearing of the air suspension blower vibrates excessively and bears impact loads, seriously affecting the stability of the lubricating film.

5、空氣懸浮鼓風機軸承冷卻水量不足或中斷，影響熱量的帶出，而使軸承溫度升高。

5. Insufficient or interrupted cooling water for the bearings of the air suspension blower affects the heat transfer, resulting in an increase in bearing temperature.

6、空氣懸浮鼓風機軸承質量不良。滑動軸承刮研質量不良，烏金接觸不好或脫胎;滾動軸承滾動體面有裂紋、碎裂、剝落等，都會破壞油膜的穩定性與均勻性，面使軸承發熱。

6. The bearing quality of the air suspension blower is poor. Poor scraping and grinding quality of sliding bearings, poor contact with black gold, or tire detachment; Cracks, fragmentation, and peeling on the rolling surface of rolling bearings can damage the stability and uniformity of the oil film, causing the bearing to heat up.
