摘　　要：建立面齿轮等温点接触弹流润滑模型,通过F O R T R A N语言编程计算面齿轮的油膜厚度和压力;分析小齿轮转速、面齿轮所受载荷和润滑油黏度对面齿轮润滑特性的影响。研究结果表明:转速和润滑油黏度越大,油膜厚度也越大,而载荷越大油膜厚度越小;二次压力峰随转速和润滑油黏度的增大而越明显,但随载荷的增大而趋于消失。Face-gear isothermal point contact elastohydrodynamic lubrication model is established. Oil film thickness and pressure of the gear is calculated by FORTRAN programming. The influences of small gear rotatory speed, load of face gear and lubricant viscosity on the lubrication characteristics of face-gear are analyzed. The results show that the oil film thickness increases with the increment of rotatory speed and oil viscosity, and the film thickness becomes smaller as the load increases. The secondary pressure peak appears more obvious with the increase of rotatory speed and lubricant viscosity, and along with the increase of load, it tends to disappear.
