摘　　要：为了研究圆周侧隙对农业智能小车使用的舵机传动性能的影响,使用RecurDyn建立了小型舵机模型,在各组齿轮圆周侧隙的允许范围内,通过调整舵机齿轮组的齿轮齿厚,得到了不同圆周侧隙变化;对舵机模型进行加速、减速及正反转仿真,得出圆周侧隙为0.130 mm时,舵机输出齿轮8的精度相对较高,回差较小。研究结果为解决智能小车行驶精度问题提供了依据。In order to study the factors affecting the transmission performance of the steering gear used in agricultural intelligent cars,a small steering gear model is established by RecurDyn.Within the allowable range of the circumferential backlash of each gear group,the changes of different circumferential backlashes are obtained by adjusting the tooth thickness of the gear group.The simulation of acceleration,deceleration and forward and reverse rotation of the steering gear model shows that when the circumferential backlash is 0.130 mm,the accuracy of the output gear 8 of the steering gear is relatively high and the return error is small.This research provides a basis for solving the driving accuracy problem of intelligent cars.
