摘　　要：针对现有抽油机换向装置存在的效率低、稳定性差等问题,设计一种非圆齿轮行星轮系换向装置。该装置采用W-W型行星轮系,应用非圆齿轮传动,在输入端角速度恒定的情况下实现输出端的正反转运动,从而完成抽油机的自动换向。齿轮传动具有传动效率高,稳定性好的特点,可有效解决抽油机换向时存在的问题。通过换向装置设计实例,进行理论分析及ADAMS仿真,分别得到输出摆角及角速度变化曲线图,通过对比分析,从理论上验证了该设计可实现抽油机的平稳换向。Aiming at the problems such as low efficiency and poor stability of the existing pumping unit reversing device,a non-circular gear planetary gear reversing device is designed. In this device,W-W type planetary gear train and non-circular gear transmission are applied. In the condition of constant input angular velocity,the device can realize the positive inversion motion of the output and the automatic commutation of the oil pumping unit is completed. Gear transmission has the characteristics of high efficiency and good stability that can solve the problem of the existing pumping unit reversing device effectively. Through the reversing device design examples,the theoretical analysis and ADAMS simulation are carried out,output swing curve of angle and angular velocity are obtained. Comparative analysis proved that the design can realize smooth commutation pumping theoretically.
