| 摘 要： | 利用空间点接触齿面啮合理论的矢量法，推导啮合点位置、接触点曲率半径和齿面上接触点的运动速度及其方向。以轮齿加载接触分析（ＬＴＣＡ）方法确定各瞬时单齿承载百分比。计算两齿面间的油膜厚度和膜厚比，作为润滑状态的理论判据。同时以扫描电镜观测分析３００小时台架试验后的齿面形貌，结合理论判据，确定典型工况下的弧齿锥齿轮齿面润滑状态。

| Abstract: | The vector method of the gear engagement theory is used to describe the manufacturing and meshing process of the spiral bevel gears in the aeroengine.The geometry and kinematic parameters of each contact point are considered,including the position,the curvature and the speed of each contact point on the tooth surface.The load on tooth in each contact position is determined with the help of Loaded Tooth Contact Analysis (LT CA) and the thickness of oil film on each contact position is obtained as theoretical foundation for judging the lubrication state.Meanwhile,300 hours test of the gears has been made and the topographical feature of the tooth surface by means of scanning electron microscope is investigated.The results of calculation and experiment show that the gears are under boundary lubrication and partial elasto-hydrodynamic lubrication. |
