(五)具体实施方式(5) Specific implementation methods
下面结合实施例对本实用新型作进一步说明，但本实用新型的保护范围并不限于此。The utility model will be further described below in conjunction with the embodiments, but the protection scope of the utility model is not limited thereto.
参照图1,一种异型密封结构的汽车轮毂轴承，包括轴承外圈1、轴承内圈2、安装在轴承外圈1和轴承内圈2之间的保持架3和滚动体4、密封圈与防尘盖6构成密封圈组件5。密封圈组件不高于轴承外圈端面。Referring to Fig. 1, an automobile hub bearing with a special-shaped sealing structure includes a bearing outer ring 1, a bearing inner ring 2, a cage 3 and rolling elements 4 installed between the bearing outer ring 1 and the bearing inner ring 2, the sealing ring and the bearing inner ring 2. The dust cover 6 constitutes the sealing ring assembly 5 . The sealing ring assembly is not higher than the end face of the bearing outer ring.
参照图2，密封圈有四个唇口，分别与防尘盖各表面均有接触，密封圈的径向唇口5a与防尘盖的外径6a有效接触，低位副唇5b和高位副唇5c与防尘盖的内壁6b有效接触，密封圈倒勾唇5d与防尘盖外侧平面6c有效接触。防尘盖6与密封圈构成的“多点紧密贴合”和多级A、B、C密封腔体的异型密封组件。各密封腔内涂有适量润滑脂。并反向安装。Referring to Figure 2, the sealing ring has four lips, which are respectively in contact with the surfaces of the dust cover, the radial lip 5a of the sealing ring is in effective contact with the outer diameter 6a of the dust cover, the lower auxiliary lip 5b and the upper auxiliary lip 5c is in effective contact with the inner wall 6b of the dust cover, and the undercut lip 5d of the sealing ring is in effective contact with the outer plane 6c of the dust cover. The "multi-point tight fit" formed by the dust cover 6 and the sealing ring and the special-shaped sealing assembly of the multi-stage A, B, and C sealing chambers. Appropriate amount of grease is applied in each sealing cavity. And install in reverse.
可阻止外部水、泥沙等污物进入轴承内部和阻止润滑脂向外泄漏。并且要通过密封腔A、B、C向进入或反向流出向外泄漏将逐层困难。It can prevent external water, sediment and other dirt from entering the bearing and prevent grease from leaking outward.
