摘　　要：以圆弧-抛物线构型点接触齿轮为研究对象,结合Adams动力学分析软件,深入研究了其动力学性能及相关特性变化规律。首先,基于空间曲面啮合基本原理,推导了圆弧-抛物线构型点接触齿轮的齿面方程,依据给定设计参数,建立了啮合齿轮副的三维模型;其次,基于Adams建立圆弧-抛物线构型点接触齿轮虚拟样机,仿真后得到齿轮法向接触力、周向力、径向力和轴向力的变化规律,对比分析了同参数、工况下圆弧-抛物线构型点接触齿轮和普通渐开线斜齿轮的法向接触力变化规律以及啮合刚度对齿轮法向接触力的影响。研究结果表明,圆弧-抛物线构型点接触齿轮的动态性能在一定程度上优于同参数、同工况下的普通渐开线斜齿轮,传动更平稳;啮合刚度对圆弧-抛物线构型点接触齿轮的动态性能有一定的影响,在合理的范围内啮合刚度越大,齿轮的传动越平稳。研究结论可为圆弧-抛物线构型点接触齿轮的设计提供依据。Taking the point contact gear with circular-parabola configuration as the research object,based on the Adams dynamic analysis software,dynamic characteristics and the variable law of tooth surfaces are studied in this study.Firstly,according to space meshing theory,tooth surfaces equation of the point contact gear with circular-parabola configuration is derived,and three-dimensional solid models of gear pairs are established by the given design parameters.Secondly,the virtual prototype of point contact gears with circularparabola configuration is established utilizing Adams software.Through simulation process,variation law of normal contact force,circumferential force,radial force and axial force of the gear are discussed.Change law of normal contact force under the same parameters and working conditions are analyzed between the point contact gear with circular-parabola configuration and general involute helical gears.Influences of meshing stiffness on normal contact force of the gear are also discussed.Research results show that the dynamic performance of point contact gears with circular-parabola configuration is better than that of general involute helical gears under the same parameters and working conditions.Meshing stiffness has a certain influence on the dynamic performance of tooth surfaces.For a reasonable variable range,the transmission process will be more stable with the increase of the meshing stiffness.The study can provide a basis for the design of point contact gears with circularparabola configuration.
