点接触CATT齿轮润滑油膜厚度的实验研究

Experimental Research for Point Contract CATT Gear Lubricating Oil Film Thickness

介绍用电阻法测量CATT（Circdar－Arc－Tooth－Trace）齿轮润滑油膜的测量原理、实验设备和方法，研究了油膜沿啮合线和沿齿线的变化规律，得出了可供CATT齿轮设计参考的结论。

?This paper introduces measuring CATT with resistance method,the measureng principle of gear lubricating oil film, experimental equipment and its method. The changing law of the film along tooth gearing and tooth trace is explored, and the reference conclusions for gear desigh are submited.
