摘　　要：针对我国齿轮胶合承载能力计算方法标准等同采用ISO相关标准,其主要计算及试验数据是否适用于国产齿轮材料及加工工艺的问题,对国产6种硬齿面齿轮材料,采用FZG齿轮试验机法及MM-200滚子摩擦磨损试验机法,分别进行了齿轮胶合失效载荷级、滚子干摩擦系数测试及材料中合金元素的含量分析,提供了齿轮胶合强度计算用的抗胶合承载能力试验数据。研究结果表明:采用干摩擦系数来估算处于边界润滑状态的齿轮胶合失效时的齿面赫兹应力是可行的;硬齿面齿轮材料中,合金元素含量对材料的导热系数及硬齿面齿轮胶合承载能力影响较大;相比其它5种经渗碳淬火处理的齿轮材料,经离子氮化处理的25Cr2MoV材料有着较高的抗胶合承载能力。In order to solve the problem of our standards of gear scuffing load capacity calculation methods were equivalent to the ISO related standards,the calculation and test data may not apply to our commonly used gear materials and processing technology,six kinds of gear materials which were widely used in China were tested by FZG tester and MM-200 tester.After the experiment of the failure load level of gear scuffing and dry friction coefficient of roller,content of alloying elements in the materials was analyzed.The test data was provided to do the gear scuffing calculation.The results show that dry friction coefficient can be used to estimate the Hertzian stress on the tooth surface when the gear scuffing in the condition of boundary lubrication.The content of alloy elements has a great influence on the heat conductivity coefficient of materials and scuffing load capacity of harden surface gears.25Cr2MoV with ionic nitriding has better scuffing load capacity to the other five kinds of carburizing and quenching materials.
