摘　　要：对齿轮进行静强度校核时,传统的方法是根据理论公式计算进行强度的校核,这种方法计算强度大、效率低;目前,应用较为广泛的方法是借助于计算机及有限元分析软件模拟齿轮在实际工作载荷下产生的应力,为产品开发提供依据,大大的降低了产品开发的周期。在运用计算机模拟分析齿根应力时,轮齿上施加载荷的方式有三种:将载荷施加到单齿对啮合区外界点、齿顶和分度圆。通过实例,对三种加载方式下的齿根应力分别进行有限元分析,结果表明,将载荷加载在单齿对啮合区外界点时得到的齿根应力最接近于理论计算的结果。When static intension of the gear is checked,the traditional method to check the stress of gear is based on the theoretical formula calculation,which intensity in computation is large and inefficient;At present,the technique widely used is by means of computers and finite element analysis software to simulate the stress of tooth root in practical working load,which provides reference for the product development,and reduce product development cycles significantly.In analyzing the stress of the gear root by computer,three methods are available for loading force：load force on the external single contact point between single tooth and meshing area,or on the tooth top,or on the pitch circle.Then finite element analysis for stress of tooth root is done with 3 loading methods respectively,which results show that the stress of tooth root is close to the theoretical computation with the loading at external contact point between single tooth and the meshing area.
