Abstract

本发明涉及一种推力滚子轴承,包括轴圈、保持架和座圈,在轴圈、保持架和座圈的周向上均设有用于径向拆装轴承的缺口,座圈的缺口处具有与缺口吻合的补缺体。所述补缺体的底部设有座圈的周向定位块。本发明在轴承上整体开设一个缺口,实现了轴承的径向装拆;而在座圈的缺口上安装上补缺体后就形成一个完整的轴承座圈,为保持架的圆周运动提供了一个完整的平面,同时改善了因开设缺口造成轴承的承载能力下降和负荷分布不均的状况,也解决了轴承运转过程中,在缺口处造成保持架变形和滚动体脱落的问题。补缺体上增设定位块,在轴承运转过程中,就能够对轴承座圈起到周向定位作用,从而实现保持架和滚动体在座圈上的自由转动。

Description

一种推力滚子轴承
技术领域
本发明涉及一种推力滚子轴承。
背景技术
现有推力滚子轴承的轴圈、座圈和保持架都是封闭的环形体,在使用时只能够轴向安装,但在一些特殊的设备上,如一种油田钻井设备上使用的中心管,为了方便其拆装操作,将中心管的轴向装卸改为径向装卸,这就需要有可以径向拆装但又不影响正常使用功能的推力滚子轴承与之配套,然而目前,还没有这种结构的推力滚子轴承来满足上述设备的要求。
发明内容
本发明的目的是提供一种可以径向拆装但又不影响正常使用功能的推力滚子轴承。
为实现上述目的,本发明采用如下技术方案:一种推力滚子轴承,包括轴圈、保持架和座圈,在轴圈、保持架和座圈的周向上均设有用于径向拆装轴承的缺口,座圈的缺口处具有与缺口吻合的补缺体。
所述补缺体的底部设有座圈的周向定位装置。所述周向定位装置是一定位块。所述定位块通过螺钉与补缺体连接。
本发明在轴承轴圈、保持架和座圈的周向上整体开设一个缺口,实现了轴承的径向装拆;而在座圈的缺口上安装上补缺体后就形成一个完整的轴承座圈,为保持架的圆周运动提供了一个完整的平面,同时改善了因开设缺口造成轴承的承载能力下降和负荷分布不均的状况,也解决了轴承运转过程中,在缺口处造成保持架变形和滚动体脱落的问题。补缺体上增设定位块,在轴承运转过程中,就能够对轴承座圈起到周向定位作用,从而实现保持架和滚动体在座圈上的自由转动。
附图说明
图1是本发明的结构示意图;
图2是图1的俯视图。
具体实施方式
图1、图2所示的推力滚子轴承,包括轴圈1、保持架4和座圈5,在轴圈1、保持架4和座圈5的圆周上均设有用于径向拆装轴承的缺口,图1中,3是保持架的缺口,2是轴圈的缺口,座圈的缺口处具有与该缺口吻合的补缺体6,补缺体6的底部通过螺钉安装有座圈5的周向定位块7,当然,在实施时,周向定位块7也可以根据实际情况选择不同的周向定位结构形式,比如定位销、定位孔、定位槽或者定位键等,均能实现座圈圆周方向的定位。
该轴承利用补缺体6将带缺口的座圈5形成一个完整的轴承座圈,使用安装时,用螺钉将补缺体6和定位块7连接成一体镶装到需要安装轴承的底座的缺口处,这样在运转过程中,就能够对座圈5起到周向定位作用,从而实现保持架4和滚动体在座圈5上的自由转动,同时也为保持架4的圆周运动提供了一个完整的平面。虽然保持架4带有缺口3,但缺口对保持架和滚子的整体转动影响不大,现有滚子数量已能满足工作载荷的要求。当滚子转动到座圈5与补缺体6的接缝处时,两者是点接触而非线接触,所以不会对滚子造成挤压变形。
当需要径向装拆设备上安装本轴承的零部件时,可先拿掉补缺体和定位块组件,再使保持架缺口3与座圈、轴圈的缺口2对齐,即可实现径向装拆。
