Abstract

本实用新型为变速箱副箱输出轴专用轴承，是一种滚动轴承。通过整体的轴承外圈构成双列圆锥滚子轴承，改变了原用两个单列轴承组合成双列结构的形式，提高了轴承的刚性，解决了轴承的承载问题，同时便于轴向游动量的调整。本轴承由内圈、外圈、滚动体、筐形保持架和内隔圈组成，外圈为整体结构，其外表面为圆柱形，一端有凸缘，内表面中段为圆孔，两头为锥孔，内圈、滚动体、筐形保持架组成两个内组件，对称的装于外圈内腔两头，中间装有内隔圈，构成完整的双列圆锥滚子轴承。本实用新型装于重型汽车变速箱副箱输出轴上，作为承载轴承。

Description

变速箱副箱输出轴专用轴承
技术领域
本实用新型涉及滚动轴承，具体是一种变速箱副箱输出轴专用轴承。
背景技术
目前重型汽车变速箱副箱输出轴所用轴承为两套单列圆锥滚子轴承，经内、外隔圈隔离而简单的组合在一起，成为双列轴承。通过多年的使用实践，证明这种结构存在如下缺点：1.零件数量偏多，增加了制造和装卸的工作量；2.轴向游动量调整不便，而这类轴承的工作状态要求必须有一定的轴向游动量；3.刚性差，此类轴承主要起支撑作用，应能承受径向负荷和一定轴向负荷的联合载荷，现有轴承满足不了此要求，应予改进。
发明内容
针对现用轴承存在的缺陷，经实验研究，对其结构进行了改进，提供一种变速箱副箱输出轴专用轴承，以满足重型汽车制造行业的需求。
技术方案
变速箱副箱输出轴用轴承包括内圈、外圈、滚动体、筐形保持架和内隔圈，所述外圈为一整体结构，其外表面为圆柱形，一端有凸缘，内表面中段为圆孔，圆孔段两端为圆锥孔，内圈、滚动体、筐形保持架组装成两个不可分离的内组件，外圈内腔中部安装内隔圈，两个内组件对称的装在内隔圈两侧，构成整体的双列圆锥滚子轴承。
有益效果和现用同类轴承比较，本实用新型的优点是：1.外圈为整体结构，使得轴承为一个整体的双列圆锥滚子轴承，不再由两部分简单组合，因而增加了轴承的刚性，满足了承受径、轴向联合载荷的要求；2.零件数量相对减少，简化了加工、装配工序，降低了生产成本，提高了经济效益；3.整体外圈一端的凸缘便于轴向准确定位，通过调整内隔圈的宽度可方便的调整轴承的轴向游动量。
附图说明

具体实施方式
下面结合附图说明本实用新型的具体实施方式，如图所示，变速箱副箱输出轴专用轴承由内圈1、滚动体2、筐形保持架3、外圈4和内隔圈5组成，外圈4为整体结构，外表面为圆柱形，一端有凸缘，内表面中段为圆形孔，圆孔两侧为圆锥孔，该锥孔的角度为滚动体2的角度，与内圈1上的锥角之和构成轴承工作面。内圈1、滚动体2和筐形保持架3组成不可分离的内组件，共两件；内隔圈5装于外圈4内腔中部的圆形孔中，两个内组件对称的装于内隔圈5的两侧，构成整体的双列圆锥滚子轴承。
内隔圈5制成宽度不等的系列件，以便配制出不同轴向游动量。
