摘要
为研究斜齿轮副啮合过程中螺旋角与驱动扭矩对斜齿轮副动力学特性的影响,建立了基于时变啮合刚度与齿侧间隙的斜齿轮副6自由度弯扭轴耦合动力学模型。利用斜齿轮副瞬时接触线,计算理论时变啮合刚度;结合齿侧间隙函数,通过4阶龙格库塔数值积分法,求解斜齿轮副的振动响应,分析螺旋角与工况对斜齿轮副振动响应的具体影响。研究发现,随着螺旋角的增大,斜齿轮副主动轮的轴向振动位移明显增大,且不同工况下的斜齿轮副振动响应也有很大区别。
In order to study the influence of spiral angle and driving torque on the dynamic characteristics of helical gear pair in the meshing process of helical gear pair,a 6-DOF coupling dynamic model of helical gear pair based on time-varying meshing stiffness and tooth side clearance was established.The theoretical time-varying meshing stiffness is calculated by using the instantaneous contact line of the helical gear pair.Combined with the tooth side clearance function,the vibration response of the helical gear pair is solved by the fourth-order Runge-Kutta numerical integration method,and the specific influence of the helix angle and working condition on the vibration response of the helical gear pair is analyzed.It is found that the axial vibration displacement of the driving wheel of the helical gear pair increases significantly with the increase of the helix angle,and the vibration responses of the helical gear pair under different working conditions are also very different.
