The invention provides an adjustable clearance eliminating structure, a worm and gear mechanism and a vehicle, the clearance eliminating mechanism comprises an auxiliary shell, a bearing sleeve, a limiting piece and an elastic piece, and the bearing sleeve moves in the axial direction of a mounting cavity formed by the auxiliary shell under the action of elastic force applied by the elastic piece so as to eliminate the meshing clearance between a worm gear and a worm. According to the technical scheme provided by the invention, the certain included angle is formed between the moving direction of the bearing sleeve and the axial direction of the worm, so that when a radial or axial gap is generated between the worm gear and the worm, the radial or axial gap can be automatically eliminated by pushing the bearing sleeve to rebound through the elastic piece; therefore, the conditions that the meshing clearance is increased due to the problems of abrasion and the like and abnormal sound is generated in the operation process of the mechanism are effectively avoided, and free regulation and control of the resilience force can be achieved by adjusting the position of the limiting piece in the adjustable assembly area. The adjustable gap eliminating structure provided by the invention is relatively simple in composition and assembly, and has a promotable value.
本公开提供了一种可调间隙消除结构、蜗轮蜗杆机构及车辆,其中间隙消除机构包括辅助壳体、轴承套、限位件以及弹性件,其中轴承套受弹性件施加的弹力作用,沿辅助壳体形成的安装空腔的轴向进行移动,以消除蜗轮和蜗杆间的啮合间隙。通过本公开提供的技术方案,由于轴承套的移动方向与蜗杆的轴向呈一定夹角,当蜗轮和蜗杆之间产生径向或轴向间隙时,通过弹性件推动轴承套的回弹能够自动消除径向及轴向间隙,从而有效避免了避免因磨损等问题引发的啮合间隙增大以及机构在运行过程中产生异响等情况,并通过调整限位件在可调装配区域中的所处位置能够实现对于回弹力的自由调控。本公开提供的可调间隙消除结构组成及装配均较为简易,具有可推广价值。
