Description

说 明 书 轴承与压板连接装置 技术领域
本实用新型涉及一种变速箱内轴承与压板之间的连接结构。 背景技术
变速箱内的传动轴通过轴承与箱体相支承，轴承一般由压板定位 于箱体上。所述轴承与压板常规的连接方式， 是在轴承与压板之间设 置一个形状不规则的卡簧， 该卡簧套装于轴承的外圈， 且卡簧的外壁 上设有三个凸包， 各凸包卡入压板内壁对应设置的凹坑中。 以上结构 的不足在于：
1 ) 卡簧形状不规则， 并且卡簧上有三个形状复杂的凸包， 一方 面加工制作困难， 另一方面， 凸包的凸出量必须控制严格， 凸出量过 多， 会增加卡簧与压板安装的难度， 凸出量过少， 压板安装的可靠性 较差， 有脱落的风险。
2 ) 压板的内壁有三个形状复杂的凹坑， 加工工艺复杂， 会增加 生产成本。
3 ) 压板与轴承之间的装配工序多， 装配操作较为繁琐， 组装效 率低。
实用新型内容 本实用新型所要解决的技术问题在于提供一种易于装配、并且可 靠性好的轴承与压板连接装置。
本实用新型的技术方案如下： 一种轴承与压板连接装置， 包括轴 承 （1 ) 和压板 （2)， 其特征在于： 所述压板 （2 )通过装配孔压装于 轴承（1 ) 的外圈上， 在压板（2 )装配孔的内壁上一体形成有一圈环 形凸台 （2a)， 该环形凸台 （2a)嵌入轴承（1 )外圈外壁上开设的环 槽 （la) 中。
本实用新型取消了传统结构中的卡簧，采用压板上的环形凸台与 轴承外圈的环槽卡接配合， 一方面零部件更少， 并且环形凸台和环槽 的加工工艺简单， 有效降低了生产成本； 另一方面， 通过一次压装即 可实现压板与轴承的装配， 装配工序少， 安装操作简单， 能大大提高 装配效率。 装配到位后， 压板与轴承之间连接可靠， 环形凸台起轴向 限位的作用， 以防止压板从轴承上脱落； 同时， 压板能相对轴承发生 周向旋转， 以便于压板与变速箱箱体上的安装孔对位。
所述压板（2 )由热轧钢板制成， 轴承（1 )的外圈由轴承钢制成。 压板的强度较低而轴承外圈的强度高， 这样压装装配更容易； 压板具 有良好的韧性及延展性， 在压装过程中不会发生损坏。
在所述轴承（1 )外圈外壁的端部设有导向锥面（lb)。 导向锥面 一方面起引导的作用， 以便于压板压装； 另一方面， 导向锥面能够减 小压板的压装阻力， 使压装过程更快捷。
作为优选， 所述环槽 （la) 槽口的两边均倒有圆角。 为了进一步减小压装阻力， 所述压板 （2 ) 装配孔装入方向的孔 口为喇叭形敞口结构。
有益效果： 本实用新型结构简单， 加工制作容易， 通过一次压装 即可实现装配， 装配操作便捷、 效率高， 不仅连接的可靠性好， 而且 能大大降低生产成本。

具体实施方式
下面结合附图和实施例对本实用新型作进一步说明：
如图 1、 图 2、 图 3所示， 本实用新型由轴承 1和压板 2构成。 其中， 轴承 1的外圈由轴承钢制成， 在轴承 1外圈的外壁上形成有台 阶面，该台阶面上开有环槽 la。所述环槽 la槽口的两边均倒有圆角， 在所述轴承 1外圈外壁的端部设有导向锥面 lb。 所述压板 2为三角 形平板结构，并由热轧钢板制成。在压板 2的中部开有圆形的装配孔， 该压板 2装配孔装入方向的孔口为喇叭形敞口结构，并且装配孔的内 壁上一体形成有一圈环形凸台 2a， 环形凸台 2a的圆周面与装入方向 的端面之间通过圆弧过渡。所述压板 2通过装配孔压装于轴承 1的外 圈上，压板上的环形凸台 2a嵌入轴承 1外圈外壁上开设的环槽 la中。 在环形凸台 2a的作用下， 压板 2实现与轴承 1的轴向限位， 且压板 2能相对于轴承 1发生周向旋转。
尽管以上结合附图对本实用新型的优选实施例进行了描述，但本 实用新型不限于上述具体实施方式，上述具体实施方式仅仅是示意性 的而不是限定性的， 本领域的普通技术人员在本实用新型的启示下， 在不违背本实用新型宗旨及权利要求的前提下，可以作出多种类似的 表示， 如更改压板的形状或材质， 或者改变轴承的类型等， 这样的变 换均落入本实用新型的保护范围之内。
