Abstract

本发明公开了一种新型圆柱滚子轴承，包括外圈、内圈、保持架和圆柱滚子，所述圆柱滚子为空心圆柱状，圆柱滚子通过其内部穿设的空心销轴连接于保持架上，且空心销轴的中部侧壁上开设有与其内腔相通的进油孔；在圆柱滚子的外表面上开设有若干环形凹槽，在环形凹槽内沿圆周方向均布设置有若干出油孔，出油孔与圆柱滚子的内孔相连通。本发明将圆柱滚子设置为空心结构形式，滚子内孔的存在有效保证了滚子整体淬透，硬度均匀一致，整个横截面的机械性能一致，避免了端面的磨削烧伤，有效提高了滚子使用寿命。

Description

一种新型圆柱滚子轴承
技术领域
本发明属于轴承技术领域，尤其涉及一种新型圆柱滚子轴承。
背景技术
随着工业发展，越来越多的轴承被使用在各种各样的机械中，而滚子则是机械中不可缺少的零部件，目前中大型圆柱滚子轴承的滚子，在直径超过30mm时，由于通常滚子为实心结构，滚子在淬火时往往就会出现硬度不均，软点等缺陷，滚子在整个直径截面上的机械性能相差很多，寿命大大降低；另外，现有的圆柱滚子与保持架之间为滑动接触摩擦，由于保持架的原因，其内部的润滑油容易流出，从而导致润滑不充分。
发明内容
为了解决现有技术中的问题，本发明采的目的是提供一种新型圆柱滚子轴承。
为了实现上述发明目的，本发明采用如下所述的技术方案：
一种新型圆柱滚子轴承，包括外圈、内圈、保持架和圆柱滚子，所述圆柱滚子为空心圆柱状，圆柱滚子通过其内部穿设的空心销轴连接于保持架上，且空心销轴的中部侧壁上开设有与其内腔相通的进油孔；在圆柱滚子的外表面上开设有若干环形凹槽，在环形凹槽内沿圆周方向均布设置有若干出油孔，出油孔与圆柱滚子的内孔相连通。
进一步，所述空心销轴的两端口均盖设有端盖。
进一步，所述进油孔沿周向均布设置在空心销轴的外表面上。
由于采用上述技术方案，本发明具有以下优越性：
1、本发明将圆柱滚子设置为空心结构形式，滚子内孔的存在有效保证了滚子整体淬透，硬度均匀一致，整个横截面的机械性能一致，避免了端面的磨削烧伤，有效提高了滚子使用寿命。
2、通过向空心销轴内注入润滑油，通过进油孔流入到圆柱滚子内部，在通过出油孔进入到轴承内部进行润滑，润滑高效、便捷，能够有效的起到延长轴承整体使用寿命。
附图说明
图1为本发明的结构示意图；
图2为圆柱滚子的结构示意图；
图3为空心销轴的结构示意图；
图中：1、外圈；2、内圈；3、保持架；4、圆柱滚子；4.1、环形凹槽；4.2、出油孔；5、空心销轴；5.1进油孔。
具体实施方式
下面结合附图及实施例对本发明作进一步详细的说明。
如图1-3所示，一种新型圆柱滚子轴承，包括外圈1、内圈2、保持架3和圆柱滚子4，所述圆柱滚子4为空心圆柱状，圆柱滚子4通过其内部穿设的空心销轴5连接于保持架3上，且空心销轴5的中部侧壁上开设有与其内腔相通的进油孔5.1；在圆柱滚子的外表面上开设有若干环形凹槽4.1，在环形凹槽4.1内沿圆周方向均布设置有若干出油孔4.2，出油孔4.2与圆柱滚子4的内孔相连通。
所述空心销轴5的两端口均盖设有端盖。
所述进油孔5.1沿周向均布设置在空心销轴5的外表面上。
本发明在需要润滑时，将空心销轴一端口上的端盖取掉，然后向内部注入润滑油，润滑油经过空心销轴上的进油孔流入到圆柱滚子内部，并在通过圆柱滚子上的出油孔流入到环形凹槽内，随着内、外圈与滚子的相对转动，进而起到润滑轴承内部的作用；另外，环形凹槽也能起到暂时储存润滑油的作用，防止润滑油直接流出而造成浪费。
