摘要

外压轴承的总摩擦力矩由两部分组成，一部分是由Petroff公式预测的，另一部分与润滑油角动量的变化有关。用空气润滑滑动轴承进行的实验充分证实了这一分析。结果表明，在所有其他参数都指定的情况下，当选择间隙使总扭矩的25%用于改变润滑剂的角动量时，得到最小总摩擦扭矩。

The frictional torque in externally pressurized bearings

The total frictional torque in an externally pressurized bearing consists of two parts, one being that predicted from the Petroff formula and the other being associated with the change in the angular momentum of the lubricant. The analysis is fully confirmed by experiments with an air-lubricated journal bearing. It is shown that if all other parameters are specified, then the minimum total frictional torque is obtained when the clearance is chosen such that 25% of the total torque is required for changing the angular momentum of the lubricant.
