| 摘 要： | 采用转化坐标法导出两表面都有切向运动的止推动压滑动轴承的压力微分方程,并在此基础上导出两表面都有切向运动的径向滑动轴承的压力微分方程;在其他参数不变条件下,提高有效速度是提高两表面都运动滑动轴承承载能力的有效方法;对于两表面都运动的推力滑动轴承,合理组合两运动表面的楔形方向和转向是提高有效速度的关键;运用有效速度概念,为这类动压滑动轴承的工程设计给出了简便方法.

| Abstract: | The differential equations of pressure for two moving surfaces hydrodynamic sliding bearing are deduced by transforming coordinate transformation method, and the concept of effective velocity is introduced. Then a simple and convenient method for engineering design of this bearing is presented. In case that other parameters keeping constant, improving effective velocity is an efficiency way to improve the bearing capacity of two moving surfaces hydrodynamic sliding bearing. As for two moving surfaces hydrodynamic sliding thrust bearing,carefully composing the directions of wedge and rotating direction of two moving surfaces is the key to improve the effective velocity. |
