摘　　要：简要介绍了齿面修形原理,对修形参数确定的依据进行了研究,给出了常用齿面修形曲线表达式,利用自主编写的齿轮接触有限元分析软件,建立了行星风电齿轮增速器系统的有限元接触分析模型。为了分析齿轮修形对齿轮增速器系统的影响,将整个齿轮传动系统作为一个有机的整体进行齿面修形接触分析研究,分析了齿面修形前后齿间载荷分配与接触线上载荷分布情况。经过修形后的齿轮系统,齿轮间的啮合刚度变化趋于平稳,齿轮间的载荷波动减小,对齿轮系统的减振降噪具有重要意义。The principle of tooth surface modification is introduced briefly,the confirm of parameters of surface modification is studies as well as the expressions of the surface modification curve are provided.A finite element model of the increasing gearbox for the wind-driven generator of planetary configuration is built by gear contact finite element analytical software compiled independently.In order to analyze the in-fluence of surface modification upon the increasing gearbox,the entire transmission configuration is consid-ered as an organic system to carry through contact analyses of surface modification.Then the load sharing between teeth before and after modification and the load distribution on contact lines is investigated.The gear system after modifying,which change in mesh stiffness is stablized and the load fluctuation is de-pressed,is very important for reducing vibration and noise of gear transmission system.
