摘要
未修形的标准摆线针轮在传动时易卡死,为补偿加工误差和保证润滑等需要对摆线轮齿廓修形。研究正等距和正移距组合修形后,最大接触力和啮合齿数的变化情况。在满足啮合原理的条件下,以工作区间摆线轮齿廓最大程度逼近转角修形后的齿廓为优化目标,通过MATLAB优化工具箱确定等距、移距修形量。基于赫兹理论计算修形前后最大接触力和最大变形,得到理论啮合齿数。建立修形前后的Adams全刚体动力学模型,进行动力学仿真。对比仿真和理论计算结果验证模型有效性并得出修形后啮合齿数减少,最大接触力变大的结论。
The standard cycloidal pin wheel reducer being stuck easily in transmission.It＇s necessary to modify the tooth profile in order to compensate the error of manufacture,and maintain reasonable clearance for lubrication and ensure convenient installation and disassembly.Under the precondition of satisfying the meshing principle,the positive equidistance and positive shift distance are determined with approaching the tooth profile after angle modification in the working interval.The maximum contact force and maximum deformation are solved based on the theory of Hertz contact theory.Getting the number of meshing tooth.Establishing dynamic modal of the rigid body and simulating the dynamic performance in Adams.Comparing the results of simulation and theoretical calculation we can validate the validity of the modal and get the conclusion of the number of meshing teeth is reduced and the maximum contact force becomes larger after modification.
