摘要

为改善摆杆活齿的齿面接触状态,通过分析传动过程中中心轮-活齿啮合副的弹性变形变化趋势,利用等距和移距的组合修形方式,以齿面接触力最小为修形目标对中心轮齿廓修形,并研究了修形对摆杆活齿各啮合副接触力的影响。以中心轮-活齿啮合副为例,研究修形对齿面接触应力的影响。研究发现,基于啮合副弹性变形的齿廓修形方式使中心轮-活齿啮合副的最大接触力和接触应力降低10%,相较于修形前,一个推程周期内啮合副受力变化更加平缓。通过对啮合副的刚度计算发现修形后平均啮合刚度提高3%。利用Adams对虚拟样机进行运动学仿真,仿真结果显示修形后输出转速更平稳。对比Workbench有限元仿真结果验证了理论计算的正确性。

Abstract

In order to improve the tooth surface contact state of the swinging rod,the elastic deformation of the center and the movable tooth meshing pair during the transmission process is analyzed.With minimum contact force as the target,the ring profile has medicated by combinion of equidistant and displacement modification,the influence of the modification on the contact force of meshing pair as well.Taking the ring-movable tooth engagement pair as an example,it is found that the tooth profile modification method based on the elastic deformation of the meshing pair reduces the maximum contact force and contact stress of the ring-movable tooth meshing pair by 10%,compared with the change of the meshing force in one push cycle before the trimming.By calculating the stiffness of the meshing pair,the average meshing stiffness after trimming is increased by 3%.The simulation of the virtual prototype was performed by Adams.The results show that the output speed is more stable after modification.The correctness of theoretical calculation is verified compared with Workbench finite element simulation.
