Description

一种变速箱专用轴承
技术领域
本实用新型涉及一种滚动轴承，具体是一种变速箱专用轴承。
背景技术
目前所用的变速箱二轴前轴承是一种无外圈的圆柱滚子轴承组件，起浮动支承作用。其缺点是只能承受一定的径向载荷，不能承受轴向载荷，导致该部位轴承损坏较多，影响变速箱正常工作。变速箱用户多年的使用实践证实了这种情况。所以该部位轴承结构有待改进。
发明内容
针对上述情况，发明人径过分析研究，通过一系列优化设计，提出一种变速箱专用轴承，改善子轴承性能，克服了现有此类轴承的缺陷。
技术方案
本实用新型提出如下所述的技术方案：变速箱专用轴承包括内圈、滚动体和保持架，其内圈为圆锥体结构，滚动体采用圆锥滚子，保持架为筐形保持架，内圈和滚动体装于筐形保持架中，通过模具压装成不可分离的轴承内组件，即成一种变速箱专用轴承。
有益效果本实用新型和现用轴承想比，有如下显著优点：1.由于采用圆锥形内圈和圆锥滚子及筐形保持架，提高了轴承组件的使用寿命，保证了变速箱的正常工作；2.由于轴承组件在模具内压装，圆锥角公差严格，精度高，具有一定的调心性能，降低了对保持架的要求，可将保持架材料由原用的黄铜改为钢板，降低了制造成本，提高了经济效益。
附图说明
图1—原用轴承结构图
图2—本实用新型(一种变速箱轴承)结构图
图面说明
图2中：1—内圈  2—滚动体  3—筐形保持架
具体实施方式
变速箱专用轴承由内圈1、滚动体2和筐形保持架3组成。内圈1为上表面成锥形的圆锥体，滚动体2为圆锥滚子，将内圈1和滚动体2装于筐形保持架3中，在模具上压装成不可分离的轴承内组件，即成无外圈的变速箱专用轴承。
本实用新型内圈1和滚动体2用通用材料制做，框形保持架3用钢板制做。
