摘要
高速工况下,高速齿轮传动装置的动态特性对设备的可靠运行有重要影响。建立了高速斜齿轮副模型,在考虑齿轮动态激励的条件下,分析了高速齿轮传动的动态特性,进行了动力学仿真。结果表明,主动齿轮沿轴向移动0.2 mm、绕竖直方向旋转0.15°后,角速度波动幅值分别提高了6.12%、3.46%;接触力波动幅值分别提高了0.58%、4.56%;轴向位移误差对角速度的影响较大,角度误差对接触力的影响较大。加速时间从5 s增加到10 s后,角速度波动幅值降低了10.7%,角速度标准差从6.9748减少到6.406;接触力波动幅值增大了0.58%。负载从1000 N·m增大到1626.75 N·m和2000 N·m后,角速度标准差从6.9748分别减小到4.77475、4.74945,接触力波动幅值分别增大了4.3%、4.25%。额定载荷在轻载情况下,齿轮传动更加平稳;在重载情况下,角速度和接触力波动差异不明显。
The dynamic characteristics of high speed gear transmission under high speed conditions have an important influence on the reliable operation of equipment.The gear pair model is established,the dynamic characteristics of high-speed gear drive are analyzed,and the dynamic simulation is carried out under the condi-tion of dynamic excitation of gears.The results show that the fluctuation amplitude of angular velocity increases respectively by 6.12%and 3.46%,after the driving gear is moved by 0.2 mm in the axial direction and 0.15°in the vertical direction.The fluctuation amplitude of the contact force increases respectively by 0.58%and 4.56%.The axial displacement error has a greater influence on the angular velocity,and the angle error has a greater in-fluence on the contact force.When the acceleration time increases from 5 seconds to 10 seconds,the fluctuation amplitude of angular velocity decreases by 10.7%and the standard deviation of angular velocity decreases from 6.9748 to 6.406.The fluctuation amplitude of contact force increases by 0.58%.After the load increases from 1000 N·m to 1626.75 N·m and 2000 N·m,the standard deviation of angular velocity decreases from 6.9748 to 4.77475 and 4.74945,the fluctuation amplitude of contact force increases respectively by 4.3%and 4.25%,and the rated load is more stable than the gear transmission under light load.The difference of angular velocity and contact force fluctuation is not obvious in the case of heavy load.
