摘要
大马力推土机终传动齿轮承受重载荷,要求高的接触疲劳强度和齿根弯曲强度。通过测试分析,选择使用保证淬透性脱气钢22CrNi2MoNbH,并确定了渗碳、淬火热处理工艺,从而达到图样各项设计指标要求。
Final drive gear of big horsepower bulldozer should withstand heavy loads and have high contact fatigue strength and tooth root bending strength.Through test and analysis , 22CrNi2MoNbH degassed steel with enough hardenability was selected for the material of final drive gear, and the carburizing and quenching processes were determined .Each indexes of the gear product can meet the design requirements .
