1、润滑质量不良。润滑的目的，是使动静部分不直接接触产生摩擦，而形成固体与液体之间的摩擦。如果润滑数量不足或质量不良，会使动静部分直接摩擦发热，或热量不能通过润滑带走，而使空气悬浮鼓风机轴承温度升高。

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、空气悬浮鼓风机滚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。

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、密封毛毡过紧而发热。

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

4、空气悬浮鼓风机轴承振动过大而承受冲击负载，严重影响润滑膜的稳定性。

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

5、空气悬浮鼓风机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。

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、空气悬浮鼓风机轴承质量不良。滑动轴承刮研质量不良，乌金接触不好或脱胎;滚动轴承滚动体面有裂纹、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。

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.
