Abstract

一种滚动体引导滚子和保持架为组件的推力调心滚子轴承，由座圈、轴圈、一组滚动体和保持架装配而成。轴圈为无大挡边的轴圈。保持架由保持架座和保持架盖组成，一组滚动体分别放置在保持架座的对应兜孔中，保持架盖放置在保持架座的上端，保持架盖通过多个内六角圆柱头螺钉与保持架座连接，构成由滚动体球形滚动面引导保持架兜孔的球形曲面旋转的滚子和保持架组件。滚子和保持架组件放置在由座圈和轴圈之间形成的滚道内。本实用新型去掉了轴圈大挡边，改成由滚动体引导，克服了保持架磨损严重易散套，安装、拆卸方便、承载能力高、调心性能好、使用寿命长，同时减少了工序，制造成本低，提高了轴承旋转灵活性。

Description

一种滚动体引导滚子和保持架为组件的推力调心滚子轴承
技术领域
本实用新型涉及轴承制造技术，特别是涉及一种轴圈不带大挡边，由滚动体引导的滚子和保持架为组件的推力调心滚子轴承。
背景技术
以往设计的滚子和保持架为组件的推力调心滚子轴承采用保持架引导，内圈大挡边对保持架进行引导限位，该轴承保持架易出现掉铜屑现象，发生断裂，造成轴承早期失效结构如（图2）所示。
实用新型内容
本实用新型要解决的技术问题是，保持架磨损严重导致轴承早期失效。为了解决由大挡边限位导致保持架断裂的问题，提供一种滚动体引导的滚子和保持架为组件的推力调心滚子轴承，无需重新设计保持架结构及制作胎具，节约成本，又轴承不易散套，提高了轴承的使用寿命。
采用的技术方案是：
一种滚动体引导滚子和保持架为组件的推力调心滚子轴承，由座圈、轴圈、一组滚动体和保持架装配而成。所述的轴圈为无大挡边的轴圈。所述保持架由保持架座和30#或35#钢制成的保持架盖组成，一组滚动体分别放置在保持架座的对应兜孔中，保持架盖放置在保持架座的上端，保持架盖通过多个内六角圆柱头螺钉与保持架座连接，内六角圆柱头螺钉与保持架盖焊接固定，构成滚动体球形滚动面引导保持架兜孔的球形曲面旋转的滚子和保持架组件。所述滚子和保持架组件放置在由座圈和轴圈之间形成的滚道内，构成一种滚动体引导的滚子和保持架为组件的推力调心滚子轴承。
本实用新型克服了保持架磨损严重易散套的问题，该轴承去掉了大挡边，改成由滚动体引导，避免了保持架与大挡边产生的摩擦力矩，磨损和打滑现象。去掉了大挡边，保持架磨损降低，不易散套，安装、拆卸方便、承载能力高、调心性能好、使用寿命长，同时减少了工序，制造成本低，提高了轴承旋转灵活性。
附图说明
图1是本实用新型的结构示意图。
图2是以往的轴承结构示意图。
具体实施方式
一种滚动体引导滚子和保持架为组件的推力调心滚子轴承，由座圈1、轴圈2、一组滚动体3和保持架7装配而成。所述的轴圈2为无大挡边8的轴圈。所述保持架7由保持架座6和30#或35#钢制成的保持架盖5组成，一组滚动体3分别放置在保持架座6的对应兜孔中，保持架盖5放置在保持架座6的上端，保持架盖5通过多个内六角圆柱头螺钉4与保持架座6连接，内六角圆柱头螺钉4与保持架盖5焊接固定，构成滚动体球形滚动面引导保持架兜孔的球形曲面旋转的滚子和保持架组件。所述滚子和保持架组件放置在由座圈1和轴圈2之间形成的滚道内，轴圈带动滚动体旋转，利用滚动体的球形滚动面引导兜孔的球形曲面，实现保持架的旋转，提高了轴承旋转的灵活性，减少保持架的磨损，提高轴承使用寿命。
