单列圆柱滚子轴承
后退 单列圆柱滚子轴承通常是只受径向力,与同尺寸球轴承相比,径向承载能力提高1.5-3倍,刚性好、耐冲击,它特别适用于刚性支承的、又支承短轴、受热伸长而引起轴向位移的轴和安装拆卸需要分离型轴承之机器附件。主要用于大型电机、机床主轴、发动机前后支承轴、火车客车车箱轴[1]支承、柴油机曲轴、汽车拖拉机变速箱等。
单列圆柱滚子轴承组成及作用
单列圆柱滚子轴承,包括外圈、内圈锁紧圈和保持架。外圈的外壁面中间设有环形应力槽,外圈的外壁上有多个环形锁紧槽,锁紧圈的形状和大小与环形锁紧槽的形状和大小相适应。环形锁紧槽内装设有锁紧圈。外圈内壁的环面上与应力槽相对应部位设有环形保持架引导槽。本实用新型具有组装方便、承载负荷大,极限转速高、可靠性强、使用寿命长等优点。
