42CrMo Hard Surface Gear Intensity Tests and Modified Parameter Correction

Abstract:

Hard surface gears drive is considering mainly how to improve the tooth root bending fatigue strength and wear resistance of the teeth. Based on the analysis of sliding ratio, coincidence degree and the gear tooth root bending fatigue strength, basic parameters of gear can be modified to improve strength. Although these gears must be cut by the standard tools, high strength gears are needed in machinery. In this research, intensity experiments were conducted with 42CrMo modified and standard hard surface gears. Experiment results show that the improvements of 42CrMo gear parameters are effective and teeth strength is improved for the modified parameters of gears.
