Roller bearing capacity optimization gear teeth of the gear machining process

optimization gearhead heat treatment processes generally mechanical gear is not just the surface hardness of the Cycloidal Speed Reducer Gearbox to the decision, it is also being affected by the surface shear stress to the core of the transition region and the ratio of the size of the shear strength, the ratio should not exceed 0.55. The best way to deal with hardened gear reducer is deep carburizing, it can get sufficient depth of hardened layer, the smaller the transition area as well as a relatively high residual tensile core hardness. Typically the carbon content of the tooth surface is preferably controlled at between 0.8% and 1%, from the tooth surface to the core hardness gradient to ease.
Optimizing machining hobbing process, make rough rolling and finish rolling step processed separately, before fine-dedicated hob hobbing first rough cut with hob, use a dial indicator Cutting depth control, to maintain its precision Cutting depth error to near zero float in, fine tooth hobbing error can not more than 0.03 mm. Tooth machining accuracy is usually to reach more than nine, the tooth surface roughness also consistent with the design requirements. Vibration can be polished or electropolished in grinding teeth after, to improve the surface roughness. Use tooth tip relief, the tooth surface modification and large arc tooth root and other technologies to reduce or eliminate interference engagement and partial load, reduces tooth root stress concentration, increased flexibility gear elasticity. Such as for proper tooth shaving, lapping, grinding teeth and other modifications can increase the contact stress limit of fifteen to twenty-five%; for tooth longitudinally modification, such as repair flanks, can improve gear twice the service life can be reduced to about one fifth bending stress around, it can also reduce noise pollution.
