摘要
比较了齿条在单齿啮合上界点和在齿顶啮合时齿根圆弧的应力和位移情况,确定了齿条根部应力最大时的计算载荷及加载位置。分析了轮齿加载侧和非加载侧的根部应力和变形状况;计算了齿条中部齿根圆弧的应力和变形,确定了齿条齿根圆弧处最大应力的分布状况。
The stress and displacement of the tooth root arc with rack meshing at upper bound point for a pair of teeth and the top of the tooth are compared, and the load and loading position of the tooth root stress maximum for rack are determined. The tooth root stress and deformation of tooth loaded side and non - loaded side are analyzed. Be- sides, the stress and deformation of tooth root arc at the rack centre are calculated, and the tooth root stress distribu- tion of rack is determined.
