The invention discloses a worm and gear clearance adjusting mechanism for an automobile steering system. The worm and gear clearance adjusting mechanism comprises a shell, a worm, a worm gear, a worm right bearing, a worm left end bearing and an automatic worm and gear clearance adjusting component. The automatic worm and gear clearance adjusting component comprises a sliding block, a sliding block sleeve, an elastic element and a nut. The shell is provided with a mounting cavity used for containing the automatic worm and gear clearance adjusting component. A main body of the sliding block sleeve is a cylindrical workpiece with a downward opening, the upper end of the sliding block is connected with the inner surface of the sliding block sleeve in an up-down sliding mode, and the spring is arranged between the upper end of the sliding block and the upper end of the sliding block sleeve. The worm right bearing is arranged in a right bearing mounting part which is arranged at the lower end of the sliding block and extends leftwards and rightwards. An anti-escape barb for preventing the upper end of the sliding block from escaping out of the sliding block sleeve is arranged at the lower end of the sliding block sleeve. The worm and gear clearance can be adjusted according to the temperature change of the working environment of the worm and gear, and the worm and gear clearance adjusting mechanism has the advantages of simple and reasonable structure and high working reliability.

    用于汽车转向系统的蜗轮蜗杆间隙调节机构,包括壳体、蜗杆、蜗轮、蜗杆右轴承、蜗杆左端轴承、蜗轮蜗杆间隙自动调节组件。蜗轮蜗杆间隙自动调节组件包括滑块、滑块套、弹性元件、螺母。壳体设有用于容纳蜗轮蜗杆间隙自动调节组件的安装空腔。滑块套的主体为开口在下的圆筒形制件,滑块的上端和滑块套的内表面上下滑动相连,弹簧设在滑块的上端和滑块套的上端之间。蜗杆右轴承设在滑块的下端所设的、左右走向的右轴承安装部内。滑块套的下端设有防止滑块的上端逃逸出滑块套的防逃逸倒钩。本发明可以根据蜗轮蜗杆工作环境温度变化来调整蜗轮蜗杆间隙,具有结构简单合理,工作可靠性高的优点。
