上海-50型和丰收-35型拖拉机转向器均为螺杆螺母循环球式,它由转向盘、螺杆、螺母和扇形齿轮等组成,装配要点如下: (1)转向螺杆和螺母装配后,在转向盘外缘上施以不大于15N的力应能使之灵活自如地转动。 (2)调整转向螺杆轴向间隙时,先将推力轴承的滚珠上座拧紧(即没有间隙),然后再退回1/6～1/4圈。 (3)固定销与转向螺母锥形 Shanghai -50 type and harvest -35 tractor steering gear are screw nut recirculating ball, which consists of steering wheel, screw, nut and sector gear and other components are as follows: (1) After the steering screw and nut assembly, the steering A force of not more than 15 N should be applied to the outer rim of the disc so that it can be flexibly and freely rotated. (2) When adjusting the axial clearance of the screw, first tighten the ball bearing seat of the thrust bearing (ie, there is no gap), and then return to 1/6 ~ 1/4 turn. (3) Taper of fixing pin and steering nut
