| 摘要: | 为提高RV减速器的传动性能, 本文针对摆线轮齿廓的工作区域及组合修形方法等展开研究. 对应用广泛的“等距+移距”修形进行组合比较, 确定“正等距+负移距”的组合方式下初始间隙最小, 即啮合刚度最高; 分析针齿与摆线轮啮合的极限位置, 推导摆线轮的实际工作区域, 并对其采用遗传算法寻找最优修形量, 使组合修形逼近转角修形所得齿廓. 结果显示, 该方法得到的摆线轮齿廓在工作区域内更接近共轭齿廓, 且在齿顶与齿根处有合适的径向间隙, 可在提高摆线轮强度的同时有效补偿制造误差和安装误差, 对摆线轮的修形方式选择及修形量确定具有一定的借鉴意义. |
| Abstract: | In order to improve the transmission performance of RV reducer, the working area of cycloid tooth profile and the combined modification method are studied in this paper. By comparing the widely used modification of “equal distance + displacement”, it is found that the initial clearance under the combination of “positive equal distance + negative displacement” is the smallest, i.e., the meshing stiffness is the highest. The limit position of the meshing between the pin tooth and the cycloid gear is analyzed, the actual working area of the cycloid gear is deduced, and the genetic algorithm is used to find the optimal modification value, so that the combined modification can approach the tooth profile obtained by the angle modification. The results show that the cycloid tooth profile obtained by this method is closer to the conjugate tooth profile in the working area, and there is an appropriate radial clearance between the tooth top and the tooth root, which can effectively compensate both the manufacturing error and the assembly error while at the same time improving the strength of the cycloid gear. It has certain reference significance for the selection of cycloid gear’s modification mode and the determination of the optimal modification value. |
