Description

一种轮毂轴承
技术领域  本实用新型涉及一种轴承。
背景技术  目前轻型客车前轮轮轴之间设两套圆锥滚子轴承，安装时需选择调整垫片的方式对两套圆锥滚子轴承进行间隙选配，调整力矩，这样做不仅麻烦，而且也难以保证装配质量。另在轴承外部设有密封装置，该密封装置结构复杂、体积庞大、自身较重、安装繁琐成本高。
发明内容  本实用新型主要是提供一种能减少零件数量、降低安装费和成本，具有良好综合机械性能的集轮毂和法兰为一体的圆锥滚子轴承。该圆锥滚子轴承主要包括有：外圈、内圈、保持架、滚子、弹簧卡、油封和防尘盖。其中轴承外圈的外表面设有与前轮轮毂对应的外形及法兰。在外圈内设两个与其对应的内圈。这两个内圈的内周面直径与汽车前轮轴相同。该两内圈之间无隔圈直接相邻，并通过弹簧卡将它们连接，防止散套。该弹簧卡为一钢带，其上间断地设有若干对外凸块，中间有空当的每对外凸块与其它成对的外凸块又构成规则的两排。在两内圈相邻端面附近的内环面上各设一个环形凹槽，卷起的钢带两排外凸块分别置于两个内圈的凹槽内，而每对外凸块间的空当又卡在两内圈凹槽的直边上，便可将两内圈连在一起。上述这两内圈外周面分别设有与一个外圈滚道对应的单滚道，每个滚道上各设一列圆锥滚子。最好圆锥滚子滚动母线外凸即为全凸球面滚子，与其对应的内圈滚道母线和外圈滚道母线具有同样的曲率。每列滚子各设有一个将滚子隔离的保持架，最好该保持架采用玻璃纤维增强尼龙材质。在轴承的两个端面上一端采用双唇密封橡胶圈，另一端采用防尘盖密封。
本实用新型在安装前调整好游隙，安装时只需将整套轴承固定在轮毂上即可，无需重新调整。
本实用新型相比现有技术具有如下优点：1、结构简单紧凑，节约空间，零件数量少，减少累计误差，增加轴承的使用寿命；同时用户在安装时不需要调整予负荷，可以高精度控制予负荷，减少安装等失误，降低了安装费用和相关的加工成本。
2、密封件结构虽简单，但其能有效防止润滑脂泄漏，也能有效防止灰尘和泥水侵入，满足密封要求，同时力矩小温升低，使密封和高速二者兼得。
3、内外圈滚道母线和滚子滚动母线均采用全凸设计，消除边缘应力集中，大大提高轴承使用寿命。
4、保持架重量轻，耐磨性、自润滑性及导热性均比金属保持架好。由于本实用新型具有上述优点，因而能很好地满足汽车轮毂轴承的高速、重载、高可靠性及长寿命等综合机械性能的要求。
