Abstract

本发明属于轴承技术领域，具体是一种滑轮组用集密封防尘与一体的双列圆柱滚子轴承。该轴承包括外圈、内圈、滚动体、内圈进油孔、止动环，所述轴承还包括防尘盖、卡槽和弹簧卡；卡槽位于外滚道上，弹簧卡嵌入卡槽内，防尘盖的外径与外滚道过盈配合，防尘盖的内径与内圈的挡边留有间隙。本发明轴承集密封防尘于一体，不仅加固了轴承的整体结构，并能防止轴承散套，不需要再采用锁圈来固定两个轴承内圈，增加了轴承的装配效率，降低了加工成本。

Description

滑轮组用集密封防尘于一体的双列圆柱滚子轴承
技术领域
本发明属于轴承技术领域，具体是一种滑轮组用集密封防尘与一体的双列圆柱棍子轴承。
背景技术
在起重运输机械、矿山机械、建筑机械、车间行车、深海工程等领域均用到滑轮组，随着现代科学技术的发展，滑轮组也经历了飞速的发展变化，而对滑轮组起旋转支撑作用的轴承在其中起到了关键的作用。滑轮组要求轻自重、高承载、高转速、便于润滑保养，与之配套的轴承也要达到这些要求。
在一些工程中，钢绳速度高，而且频繁启动，因而传统的滑轮组已难满足现代生产高效、高质量、高可靠性的要求，研发新型滑轮组得任务日益艰巨，与此同时，研发与滑轮组配套的轴承也迫在眉睫。
发明内容
本发明的目的是提供一种滑轮组用集密封防尘与一体的双列圆柱滚子轴承。
为实现上述发明目的，本发明采用以下技术方案：
一种滑轮组用集密封防尘于一体的双列圆柱滚子轴承，包括外圈、内圈、滚动体、内圈进油孔、止动环，其特征在于，所述轴承还包括防尘盖、弹簧卡；弹簧卡嵌入外滚道上的卡槽内，防尘盖的外径与外滚道过盈配合，防尘盖的内径与内圈的挡边留有间隙。
与现有技术相比，本发明的有益效果为：本发明轴承集密封防尘于一体，不仅加固了轴承的整体结构，并能防止轴承散套，不需要再采用锁圈来固定两个轴承内圈，增加了轴承的装配效率，降低了加工成本。
附图说明
图1 本发明结构示意图；
图中，01.外圈，02. 内圈，03. 滚动体，05. 防尘盖，06. 弹簧卡，07. 内圈进油孔；
图2 本发明结构局部放大图。
具体实施方式
以下结合具体实施方式对本发明做进一步说明。
一种滑轮组用集密封防尘于一体的双列圆柱滚子轴承，包括外圈01、内圈02、滚动体03、内圈进油孔07、止动环04，其特征在于，所述轴承还包括防尘盖05、弹簧卡06；卡槽位于外滚道上，弹簧卡06嵌入外滚道上的卡槽内，防尘盖05的外径与外滚道过盈配合，防尘盖05内径与内圈的挡边留有间隙。
本发明轴承将防尘盖外径与外滚道过盈配合，防尘盖内径与内圈的挡边有一定的间隙A（见附图2），保证轴承运转时润滑剂不能从轴承内部泄漏，又能在一定油压下方便地对滑轮组内部轴承润滑剂进行更换，新的润滑剂将废弃润滑剂通过防尘盖与内圈挡边的间隙A顶出，起到密封防尘的作用；弹簧卡嵌入外滚道的卡槽内，不仅加固了轴承的整体结构，并能防止轴承散套，不需要再采用锁圈来固定两个轴承内圈，增加了轴承的装配效率，降低了加工成本。
