Experimental Study on Mesh-wear of Involute Spur Gears

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.
