Description

圆柱滚子端盖轴承
技术领域：
本实用新型涉及一种圆柱滚子端盖轴承，为中型、重型汽车和工程机械用。
背景技术：
中型、重型汽车和工程机械的变速箱主轴孔为盲孔，盲孔难以加工，主轴端部使用滚针轴承，需要先安装轴承套于箱体壁上，再将滚针轴承安装于轴承套内孔与主轴的端部。工作过程中，因主轴的轴向窜动而引起滚针轴承的轴向窜动，使得轴承保持架易损，寿命降低。
发明内容：
本实用新型的目的是提供一种圆柱滚子端盖轴承，解决装配轴承的主轴孔难以加工和安装轴承效率低的缺陷；解决轴承轴向窜动容易损坏的问题。
本实用新型的目的是以如下方式实现的：该圆柱滚子端盖轴承包括外圈、滚子和保持架，若干滚子通过保持架设置在外圈的内周面处，外圈一端装置轴承端盖。由于设置了轴承端盖，变速箱主轴孔由盲孔改为通孔，加工方便；通孔的加工精度容易保证，安装轴承时可以省却轴承套。
外圈为一端有内挡边的单挡边外圈，轴承端盖处于外圈内孔中并抵靠在外圈内挡边的内侧面上。
轴承端盖为凸字型，轴承端盖变径部分圆环端面抵靠在外圈内挡边的内侧面上，轴承端盖外侧面与外圈端面平齐。
保持架的轮廓为直筒后部带凸环的结构，保持架前部插入在轴承端盖的内孔处，保持架的凸环与外圈内孔适配。
由于本实用新型带有轴承端盖，这样可以在变速箱主轴孔的加工过程中由盲孔改为通孔，加工方便；安装时不用轴承套，提高装配效率；在运转时，滚子可以沿单挡边外圈滚道带动保持架向一端自由移动，顺应主轴的轴向微窜动，延长了轴承的使用寿命；轴承端盖可以有效地防止箱体外杂物或者灰尘进入到箱体内，保证圆柱滚子轴承在不受外物干扰的情况下正常运转；圆柱滚子可以承受较大的载荷，具有较高的抗冲击能力。
本实用新型使装配轴承的主轴孔容易加工，轴承安装、维修方便，提高了轴承的安装效率；克服因轴向窜动而引起的轴承损坏，延长了轴承的使用寿命。
附图说明：
附图是本实用新型的结构示意图。
具体实施方式：
参照附图，该圆柱滚子端盖轴承包括外圈1、轴承端盖2、滚子3和保持架4。外圈1为一端有内挡边的单挡边外圈，轴承端盖2为凸字型，轴承端盖2变径部分圆环端面抵靠在外圈1内挡边的内侧面上，外圈1内挡边的内孔与轴承端盖2细径外圆为过盈配合，轴承端盖2外侧面与外圈1端面平齐，保持架4的轮廓为直筒后部带凸环的结构，保持架4前部插入在轴承端盖2的内孔处，保持架4的凸环与外圈1内孔适配，若干滚子3通过保持架4设置在外圈1的内周面处。将保持架4装入外圈1内孔后，采取内装滚子的方法将滚子3压入保持架4内；包装时为防止轴承的分离，用塑料热合的方式进行包装。轴承安装时，将本实用新型压入变速箱主轴孔后，再将主轴装入轴承内孔即可。外圈1：滚动体转动的滚道，允许滚子3轴向移动；轴承端盖2：防止外物进入轴承；滚子3：轴承滚动体，承载径向力；保持架4：保持滚子3不得掉出，引导滚子3沿滚道运转。
