The embodiment of the invention provides a bevel gear clearance adjusting method, a gear shaft clearance adjusting structure, a steering gear and a vehicle, and relates to the technical field of automobile steering systems. The bevel gear clearance adjusting method comprises the following steps that parameters of a bevel gear shaft are obtained; according to the parameters of the bevel gear shaft, the value interval of the displacement coefficient is calculated; according to the maximum value and the minimum value of the displacement coefficient, the included angle between the bevel gear shaft and the axis is calculated; obtaining a production tolerance; calculating the axial displacement range of the bevel gear shaft according to the production tolerance and the included angle; and calculating parameters of the spring according to the axial displacement range. Arranging a spring, a bevel gear shaft, a bearing and a rack; the bevel gear shaft is meshed with the rack, and the bearing sleeves the bevel gear shaft; one end of the spring abuts against the bearing, and the other end of the spring abuts against the end face of the bevel gear shaft. According to the method, the parameters of the spring for adjusting the gap can be determined according to bevel gear shafts of different specifications, so that the gap caused by abrasion between the bevel gear shafts and the rack is eliminated.

    本发明的实施例提供了一种锥齿轮间隙调整方法、齿轮轴间隙调整结构、转向器及车辆,涉及汽车转向系统技术领域。该锥齿轮间隙调整方法包括以下步骤:获取锥齿轮轴的参数;根据锥齿轮轴的参数,计算变位系数的取值区间;根据变位系数的最大值和最小值,计算锥齿轮轴与轴线的夹角;获取生产公差;根据生产公差和夹角,计算锥齿轮轴的轴向位移范围;根据轴向位移范围,计算弹簧的参数。设置弹簧并安装锥齿轮轴、轴承和齿条;锥齿轮轴与齿条啮合,轴承套设于锥齿轮轴;弹簧的一端与轴承抵持,弹簧的另一端与锥齿轮轴的端面抵持。上述方法可以根据不同规格的锥齿轮轴,确定调整间隙的弹簧的参数,以消除锥齿轮轴与齿条发生磨损导致的间隙。
