Abstract

本实用新型公开了一种球面外圈双列圆柱滚子轴承，包括外圈(1)、内圈(2)，保持架(3)和两列圆柱滚子(5)；所述外圈的外径为球面；所述两列圆柱滚子并排放置；所述内圈的一端有固定挡边(7)，用于限定于圆柱滚子的一侧，承受圆柱滚子一个方向上的径向载荷；所述内圈的另一端设置有活挡边(8)，用于限定于圆柱滚子的另一侧，承受另一方向的径向载荷。本实用新型不存在偏载现象，而且为滑动轴承和滚动轴承的组合，具有结构简单、易于加工、使用寿命长的特点。

Description

球面外圈双列圆柱滚子轴承
技术领域
本发明涉及一种轴承，更具体地说涉及一种双列圆柱滚子轴承。
背景技术
现有技术的振动筛用轴承，在其圆柱滚子轴承外设置调心滚子轴承，问题在于，轴承比较笨重，存在偏载现象。而此类机器使用的调心滚子轴承，其内、外圈滚道即承受径向负荷又承受轴向负荷。超过使用要求时，导致一列滚子过载，一列滚子卸载，纵然不严重，也会造成偏载，加速了一列轴承因疲劳受到破坏。
发明内容
针对上述问题，本发明提供了一种专用双列圆柱滚子轴承，其目的旨在提供一种可承受径向负荷，使用寿命长的轴承。
本发明提出了一种双列圆柱滚子轴承，包括外圈、内圈，保持架和两列圆柱滚子；所述的外圈的外径为球面；所述两列圆柱滚子并排放置；所述内圈的一端有固定挡边，用于限定于圆柱滚子的一侧，承受圆柱滚子在一个方向上的径向载荷；所述内圈的另一端设置有活挡边，用于限定于圆柱滚子的另一侧，承受另一方向的径向载荷。
通过上述技术方案，本发明的用双列圆柱滚子轴承，其径向和轴向分别承受载荷，不存在偏载现象，而且为滑动轴承和滚动轴承的组合，其径向负荷的承受能力也相应增大。因此本发明轴承具有结构简单、易于加工、使用寿命长的特点。
附图说明
图1是本发明双列圆柱滚子轴承的半剖结构示意图，省略下部对称结构。
具体实施方式
如图1所示，本发明的轴承由外圈1、内圈2、保持架座3、保持架盖4、滚子5和铆钉(未标出)组成。外圈的径向表面为球面，保持架盖4与保持架座3由铆钉相连接，构成保持架。保持架置于外圈1和内圈2之间。滚子5装入保持架座3的兜孔中。内圈2的一端为固定挡边7，位于一列滚子的一侧，用于承受圆柱滚子在一个方向上的径向载荷；内圈2的另一端设置有活挡边8，限定于另一列圆柱滚子的另一侧，用于承受另一方向的径向载荷。固定挡边7一侧圆柱滚子的长度较另一侧的圆柱滚子长。

Claims (2)
