The invention discloses a high-efficiency large-torque mechanical steering gear device, and relates to the technical field of mechanical steering gears. The device comprises a shell, a steering nut isarranged in the position, close to the upper side, in the shell, a first radial bearing is fixedly installed between the left side face of the steering nut and the shell, an input shaft is movably installed in the steering nut from the right side face, a second radial bearing is fixedly installed on the input shaft, the second radial bearing abuts against the right side face of the steering nut,a steel ball is arranged between the input shaft and the steering nut, and a supporting bearing is arranged between the outer surface of the steering nut and the inner wall of the shell. The supporting bearing matches the wall of the shell, the position is limited through a limiting clamping ring, the output torque is increased, the durability is improved, the service life of the steering gear boxis prolonged, a first needle roller bearing matches a second needle roller bearing, the positive efficiency of the steering gear box is greatly improved, and the return performance of the steering gear box is more excellent.

    本发明公开了一种高效率的大扭矩机械转向器装置,涉及机械转向器技术领域。包括壳体,所述壳体内靠近上侧设置有转向螺母,所述转向螺母的左侧面与壳体之间固定安装有第一向心轴承,所述转向螺母内从右侧面活动安装有输入轴,所述输入轴上固定安装有第二向心轴承,且第二向心轴承与转向螺母的右侧面相抵触,所述输入轴与转向螺母之间设置有钢球,所述转向螺母的外表面与壳体内壁之间设置有支撑轴承。本发明通过支撑轴承与壳体壁配合,和限位卡环限制位置,提高输出扭矩,改善耐久性能,提高方向机使用寿命,再通过第一滚针轴承与第二滚针轴承的配合,方向机的正效率大大提高,使方向机的回正性能更加的优异。
