摘　　要：为齿轮啮合磨损计算机仿真提供依据,在CL 100型齿轮试验机上进行了渐开线直齿圆柱齿轮啮合磨损试验,利用高精度的UMC1000C型三坐标测量仪进行了轮齿磨损前后的齿形检测·检测结果经计算机数据处理,再利用Mathematica软件绘出线磨损量线图,试验方法与理论计算方法比较,结果相符·节圆附近的磨损量最小,齿顶圆附近的磨损量最大,径向线磨损量分布的规律与齿面啮合相对速度的变化规律基本一致·A mesh-wear test was done on CL-100 Gear Test Machine for a pair of involute spur gears with the intention of providing parametric data for computerized simulation. The high-precision UMC 1000 Triaxial Measuring Instrument was used to measure the tooth profiles before and after the wear-out due to gear meshing. The test results were processed by computer, then the curves of linear wearing values of both rears are plotted by means of the software Mathematica. Comparing the calculated results with tested ones, the former is nearly in conformity with the latter. It is found that the wearing value is minimum in the vicinity of the pitch circle, while it is maximum in the radial distributions of linear wearing values are basically in conformity with that of the speed of a gear's tooth flank relative to other one's tooth flank in meshing process.
