【摘要】：摆线轮作为RV减速器的核心精密关键零件,其运行状况决定了减速器的传动精度、效率、疲劳寿命、可靠性等重要性能指标。如何确定摆线轮的最优齿廓修形参数是提高减速器传动精度、回差以及装配工艺性的关键技术。针对多种基于正等距加负移距的摆线轮齿廓修形模型,利用MATLAB工具分析各模型下的摆线针轮传动载荷分布、啮合齿对数、与转角修形共轭齿廓的趋近程度以及回转精度等特性。研究结果表明,各模型的优化参数存在一定差异,在接触齿对数、载荷分布等方面性能基本一致,修形齿廓与理论齿廓间的间隙大致相等,分布较为均匀,且修形齿廓均十分趋近转角修形共轭齿廓;基于齿廓法向间隙建立的模型既能保证同一时刻的多齿对啮合及承载的均匀性,又能得到更高的回转精度,更适合工程应用。
[Abstract]:Cycloid wheel is the key part of RV reducer. Its running condition determines the transmission accuracy, efficiency and fatigue life of the reducer. How to determine the optimal tooth profile modification parameters of cycloid gear is to improve the transmission accuracy of reducer. Aiming at many kinds of cycloid gear profile modification models based on positive equidistant plus negative shift distance, the load distribution of cycloidal needle wheel transmission under each model is analyzed by MATLAB tool. The logarithm of meshing teeth, the approaching degree of conjugate tooth profile with angle modification, and the precision of rotation, etc. The results show that the optimized parameters of each model are different in the logarithm of contact teeth. The load distribution is basically the same, the gap between the modified tooth profile and the theoretical tooth profile is approximately equal, the distribution is more uniform, and the modified tooth profile is very close to the conjugate profile of the modified angle. The model based on the normal clearance of tooth profile can not only guarantee the homogeneity of meshing and bearing capacity of multi-tooth pairs at the same time, but also obtain higher accuracy of rotation, which is more suitable for engineering application.
