摘要: Pinion gears for planetary gear transmissions are hobbed, heat treated, and then ground to get better control of the leads/profiles on all teeth. Then a light shot peening is applied tooth flanks achieve desired compressive residual stresses surface. By applying process in controlled manner specified, surface not over-cold worked. Next, chemically assisted isotropic treatment over pinion improve finish For low speed applications improves lambda ratio, allowing good oil film thickness
