Experimental Research on Grinding Surface Layer Behavior and Process Parameter Optimization of Spiral Bevel Gears

Abstract:

Based on the test analyses of grinding surface layer behavior of spiral bevel gears, many conclusions are gotten. Compressive residual stresses are occurred on grinding tooth surface, tensile residual stresses are located in tooth layer, and change laws of grinding residual stresses are different from ones of grinding surface roughness R_a as the grinding process parameters. A temper layer is occurred in tooth layer after normal grinding, and the micro-hardness of grinding surface is lower. When arriving at the critical condition, namely grinding temperature is above 600 degree Celsius, and metamorphic layer depth is greater than 0.2mm, different degree of grinding burn is produced, and their microstructures are changed. Based on grinding orthogonal test L₁₆(4⁵), the optimizing configuration of grinding process parameters of spiral bevel gear is obtained by using a mean variance analysis of integrated balance method. Based on the test optimization of grinding surface layer behavior, the comprehensive performances of grinding surface, such as grinding residual stresses, surface roughness, micro-hardness and structure, metamorphic layer depth et al, are better. These provide a basis for improvement of grinding surface quality of spiral bevel gears.
