| 摘 要： | 将刀齿和轮齿抽象简化为力学模型，分析其受力状态，并运用三维有限单元法计算各节点的弯曲变形量。运用啮合原理、微分几何和弹塑性力学等基础知识，对齿面间的几何性质和运动关系进行深入细致的分析研究，计算各瞬态啮合点的接触变形。最后综合考虑弯曲变形与接触变形，定量描述被剃齿轮齿形的“中凹”误差；对提高剃齿精度，降低齿轮传动噪声有着重要意义。

| Abstract: | Cutter teeth and gear teeth are simplified as mechanical models, The bending deformation at contact nodes is calculated by applying the three - dimension finite element method and analyzing their mechanical condition, the relation curve between shaving force and bending deformation is drawn out. The contact deformation at transient engaging point is derived from deeply analyzing geometric property and kinematics relationship between the two action flanks by use of engagement principle, differential geometry, elastic and plastic mechanics, etc. At last, the concave error of gear profile is quantitatively described by combining bending deformation and contact deformation. |
