造成離心風機軸承過熱的原因有哪些？

隧道式離心風機主要用於地下隧道通風換氣，亦可用於鐵路隧道，山洞及地下工程和建築物的通風換氣，是一種高壓力，低噪聲，高效離心風機。隧道離心風機是一種特殊的離心風機，主要用在公路、鐵路及地鐵等隧道的縱向通風系統中。造成離心風機軸承過熱的原因有哪些呢？
Tunnel centrifugal fan is mainly used for ventilation and ventilation in underground tunnels, railway tunnels, caves and underground engineering and 环氧地坪buildings. It is a high pressure, low noise and high efficiency centrifugal fan. Tunnel centrifugal fan is a special centrifugal fan印花地坪, which is mainly used in the longitudinal ventilation system of highway, railway and subway tunnels. What are the causes of overheating of centrifugal fan bearings?
1、離心風機主軸或主軸上的部件與軸承箱摩擦；
1. Friction between the parts of the spindle or spindle of the centrifugal fan and the bearing box;
2、電機軸與風機軸不同心，使軸承箱內的內滾動軸承別動；
2. The motor shaft is not concentric with the fan shaft, so that the inner rolling bearing in the bearing box does not move.
3、軸承箱體內潤滑脂過多；
3. Excessive grease in the bearing box;
4、軸承與軸承箱孔之間有間隙而松動，軸承箱的螺栓過緊或過松；
4. There is a gap between the bearing and the bore of the bearing box, and the bolt of the bearing box is too tight or loose.
