The invention relates to the technical field of mechanical transmission systems, in particular to an adjustment-free bearing and a steering drive axle thereof. A main speed reduction bearing part comprises a tapered roller bearing I and a tapered roller bearing II, and a belleville spring I, a spacer bush and a locking nut are sequentially mounted on a driving gear shaft; a flat washer is mounted on the end surface of the tapered roller bearing II; the belleville spring I applies pre-tightening force to the flat washer and the tapered roller bearing II respectively; the steering bearing part comprises a knuckle bearing I and a knuckle bearing II which are mounted on the axle housing, a belleville spring II is mounted on the axle housing, and the belleville spring II applies pre-tightening force to the knuckle bearing I; the axial clearance or the axial pre-tightening force of the cylindrical roller bearing at the position of the main speed reducer is adjusted through the belleville spring, the axial clearance or the axial pre-tightening force of the knuckle bearing at the position of the knuckle is adjusted through the belleville spring, only proper belleville spring force needs to be calculated during design, then the belleville spring force is installed in place, and extra adjustment is not needed.

    本发明涉及机械传动系统技术领域,具体涉及一种免调节轴承及其转向驱动桥。本发明的主减速轴承部包括圆锥滚子轴承Ⅰ与圆锥滚子轴承Ⅱ,主动齿轮轴上依次安装有碟形弹簧Ⅰ、隔套和锁紧螺母;圆锥滚子轴承Ⅱ的端面上安装有平垫圈;碟形弹簧Ⅰ分别对平垫圈及圆锥滚子轴承Ⅱ施加预紧力;转向轴承部包括安装在桥壳上的关节轴承Ⅰ和关节轴承Ⅱ,桥壳上安装有碟形弹簧Ⅱ,碟形弹簧Ⅱ对关节轴承Ⅰ施加预紧力;通过碟形弹簧调节主减速器处圆柱滚子轴承的轴向间隙或轴向预紧力,通过碟形弹簧调节转向节处关节轴承的轴向间隙或轴向预紧力,仅需在设计时计算出适当的碟形弹簧力,然后安装到位即可,不需额外进行调节。
