本文描述在立式涡轮分子真空泵上部使用轴颈轴承的优点。因为轴颈轴承没有机械接触,与上部使用一个球轴承的泵相比较,泵的可靠性增加了,并且系的振动特性也改进了。对轴颈轴承内部油的流体动力流场工作过程也做了一些解释。 对于使用两个球轴承的涡轮分子系来说,涡轮的极限速度
This article describes the advantages of using journal bearings in vertical turbine molecular vacuum pumps. Due to the absence of mechanical contact of the journal bearings, the reliability of the pump is increased and the vibration characteristics of the system are improved as compared to a pump with a ball bearing on the top. The hydrodynamic flow field inside the journal bearing oil also made some explanations. Turbine speed limit for turbo molecular systems using two ball bearings
