本文先分析了 ISO 标准和国标中轮齿刚度的计算方法,并对计算轮齿刚度的各种方法进行了分析比较;然后用边界元法计算单齿刚度,根据计算结果给出了经验公式和线图,并对轮体刚度进行了分析,为了在工程中考虑轮体刚度,引入了轮体尺寸系数 C_m。轮齿的刚度,在分析齿轮系统的振动,动载荷,修形和载荷分配中经常会用到,它是对齿轮传动系统进行深入分析的基础.然而,由于齿形的复杂性,轮齿变形和刚度仅是一种近似计算,而且各种方法和公式,有时有较大的差别。
This paper first analyzes the calculation method of gear tooth stiffness in ISO standard and national standard, and analyzes and compares various methods to calculate gear tooth rigidity. Then, the boundary element method is used to calculate the tooth rigidity, and the empirical formula and Line diagram, and the wheel body stiffness analysis, in order to consider the wheel body stiffness, the introduction of a wheel size factor C_m. Gear tooth stiffness, often used in the analysis of gear system vibrations, dynamic loads, trim and load sharing, is the basis for in-depth analysis of gear drive systems. However, due to the complexity of tooth profiles, And stiffness is only an approximate calculation, and various methods and formulas, sometimes have a greater difference.
