Description

圆锥滚子轴承
技术领域
本实用新型涉及一种轴承，特别是一种圆锥滚子轴承。 
背景技术
现有技术中，圆锥滚子轴承由内圈、保持架、滚子和外圈构成，外圈与内圈之间设置有保持架，滚子嵌入设置在保持架内。其中，内圈的中心孔以及外圈的外壁均为圆柱面，通常所述内圈均与圆柱轴段连接，所述外圈与圆柱孔连接，轴和轴承连接，是轴与轴承的内圈套在一起，一般都是过盈配合（轴的直径略大于轴承内圈直径）。这样轴承的内圈紧密地套在轴上，成为一体。其不足之处是：轴与轴承内圈或者机件与轴承外圈装配或者拆卸时，均需要通过工具敲击，而在敲击过程中，容易损坏轴承。 
发明内容
本实用新型的目的就是为了避免背景技术中的不足之处，提出一种结构新颖，安装和拆卸方便的圆锥滚子轴承。 
对于本实用新型的一种优化，本实用新型采用如下技术方案：圆锥滚子轴承，包括内圈、保持架、滚子和外圈，外圈与内圈之间设置有保持架，滚子嵌入设置在保持架内，所述内圈的中心孔为正多边形柱孔。 
本实用新型与背景技术相比，具有结构新颖，使用方便，所述内圈的中心孔位多边形柱孔，轴段与多边形柱孔匹配连接，其轴向通过压片固定，当需要拆卸时，仅需松开压片，即可将轴承取出。 
附图说明
图1是圆锥滚子轴承的结构示意图。 
图2是内圈的结构示意图之一。 
图3是内圈的结构示意图之二。 
图4是内圈的结构示意图之三。 
具体实施方式
实施例1：参照图1~4。圆锥滚子轴承，包括内圈1、保持架2、滚子3和外圈4，外圈4与内圈1之间设置有保持架2，滚子3嵌入设置在保持架2内，所述内圈1的中心孔1a为正多边形柱孔。 
实施例2：参照图2。所述内圈1的中心孔1a的截面为正三角形。 
实施例3：参照图3。所述内圈1的中心孔1a的截面为正五角形。 
实施例4：参照图4，所述内圈1的中心孔1a的截面为正六边形。 
    需要理解到的是：本实施例虽然对本实用新型作了比较详细的说明，但是这些说明，只是对本实用新型的简单说明，而不是对本实用新型的限制，任何不超出本实用新型实质精神内的发明创造，均落入本实用新型的保护范围。
