Distortion and control of driven spiral level gear after carburizing and quenching

MA Guang-feng1,WANG Bao-qi2(1.Tianjin Speed Reducer Co.,Ltd.,Tianjin 300161,China;2.School of Material Science & Engineering,Hebei University of Technology,Tianjin 300132,China)  
Distortion behavior of driven spiral bevel gear quenching directly after carburizing was analyzed and it represented that the main reason of the distortion was thermal stress.The gears′ distortion can be decreased remarkably by improving loading mode and make the gears cooling uniformly during quenching,therefore can obviously reduce the gear distortion.
