针对某微型电机人字沟轴承的润滑问题
基于流体力学润滑理论、采用HBFA软件、结合Fortran高级编程语言对轴承润滑性能进行了数值分析。在数值计算中采用扩展的雷诺方程对轴承有、无沟槽的油膜厚度及表面压力分布进行了分析
并在此基础上研究了动、静态载荷下轴承转速、偏心率、偏位角、温升等参数对人字沟轴承润滑特性的影响。结果表明:实验数据和仿真数据基本相符
误差在1%~4%之间; 动载荷下有沟槽轴承的油膜较厚、油膜压力呈现波动
主要分布在180°~360°区间
其中最大值在270°位置; 静载荷下光滑轴承的油膜厚度略薄
油膜压力呈现光滑分布
主要分布在0°~180°区间
其中最大值在80°位置。随着偏心率的增加
油膜厚度减小
油液温升先降低且在偏心率接近1时突然急剧增加
油膜承载能力、油液泄漏量均增大; 随着轴承转速的提高
油液温升、油膜承载能力、泄漏量均增大。该结果可为微型轴承的特性优化及微小型轴承润滑特性研究提供参考。
For the lubrication of some micro-motor herringbone groove bearing
the bearing lubrication performance is numerically analyzed by HBFA software combined with the Fortran code based on the lubrication theory of fluid mechanics. In the numerical calculation
the extended Reynolds equation is adopted to analyze the film thickness and surface pressure distribution of the groove or non-groove bearing. Following the above analysis
the effects of lubrication properties of the herringbone groove bearings in the parameter of spin axis speed
eccentricity
deviation angle
temperature and other parameters with the dynamic and static loads are discussed. And under the same load conditions
the experimental data are compared with the simulated data. The results show that the distribution of experimental data and simulation data are basically the same with deviations between 1% and 4%; the oil film of the groove bearing is pretty thick under the dynamical load condition
and the pressure of the oil film fluctuates mainly in the interval of 180°-360° and gets the maximum at 270°. But the oil film of the groove bearing is pretty thin under the static load condition
and the pressure of the oil film fluctuates mainly in the interval of 0°-180° and gets the maximum at 80°. With the increasing eccentric rate
the thickness of the oil film decreases; the oil temperature decreases but suddenly increases when the eccentric rate is close to 1; the load ability of the oil film and the leakage of the lubrication oil both increase. With the increasing bearing speed
the oil temperature increases
and the load ability of the oil film and the leakage of the lubrication oil both increase.
