【摘要】 对螺旋油楔动压滑动轴承的动静特性进行了研究、联立求解雷诺方程、油膜厚度方程和速度方程等,运用有限差分法计算得出有无考虑供油压力情况下,轴承的动静特性参数。结果表明:供油压力使滑动轴承的油膜压力总体上有所提高;供油压力对轴承的刚度系数和阻尼系数都有不同程度的影响;供油压力的存在加快了流体质点的运动,这对于改善轴承的润滑性能非常有利。因此,研究螺旋油楔动压滑动轴承的动静特性必须计入供油压力的影响。更多还原

【Abstract】 Dynamic and static characteristics of a new novel sliding bearing,the spiral oil wedge hydrodynamic bearing was investigated.By means of finite differential methods,dynamic and static parameters of bearing when considering and not considering input pressure were computed based on generalized Reynolds equation,film thickness equation and velocity equation.The results show oil film pressure increases mostly for considering input pressure.Input pressure produces different influence on dynamic stiffness and damping coefficients.Input pressure quickens lubricant oil flow,which is favorable for the bearing lubrication.Therefore,it is necessary to consider input pressure when analyzing the static and dynamic characteristics of spiral oil wedge hydrodynamic bearing.更多还原
