Abstract

一种新型卡车轮毂轴承，属于汽车用轮毂轴承技术领域，内圈、外圈为两体式结构，两外圈外内径设计一个凹槽，采用尼龙锁紧圈和两外圈过盈连接，两内圈用弹簧卡圈固定连接，滚动体、内圈、保持架组成组件，与两外圈组合，两侧分别装上第一密封圈和第二密封圈，第二密封圈外面安装防尘盖。本实用新型的有益效果：外圈采用两体式结构，普通的设备就可以磨削加工，砂轮轴无需太长，磨削难度相对降低；同样，在磨削两侧密封圈牙口时，难度也降低了很多；在使用方面，外圈两体结构对轴的挠度影响的适应性更强。

Description

一种新型卡车轮毂轴承
技术领域
本实用新型涉及一种新型卡车轮毂轴承，属于汽车用轮毂轴承技术领域。 
背景技术
卡车轮毂轴承的主要作用是承重和为轮毂的转动提供精确引导，它既承受轴向载荷又承受径向载荷，是一个非常重要的零部件，因此卡车轮毂轴承要求高承载力、防尘抗腐蚀能力强。一般的双列卡车轮毂为外圈一体，内圈两体式机构，外圈一体的轴承，外圈宽度大，需要砂轮轴更长，磨削难度大，而且两滚道需要一次磨削成形，必须使用双滚道一次磨削的设备进行磨削，对设备要求高，且在使用过程中，外圈一体式结构对轴的挠度影响的适应性不是很强。 
发明内容
鉴于已有技术存在的缺陷，本实用新型的目的是提供一种可以降低轴承的加工难度，并对轴的挠度影响的适应性更强的新型卡车轮毂轴承。 
为实现上述目的，本实用新型所采用的技术解决方案是：一种新型卡车轮毂轴承，内圈、外圈为两体式结构，采用尼龙锁紧圈和两外圈过盈连接，两内圈用弹簧卡圈固定连接，滚动体、内圈、保持架组成组件，与两外圈组合，两侧分别装上第一密封圈和第二密封圈，第二密封圈外面安装防尘盖。 
所述新型卡车轮毂轴承的装配过程如下：将滚动体放入到保持架的兜孔中，然后放入内圈，形成保持架、滚动体、内圈的内组件，然后利用尼龙锁紧圈将两个单外圈连接起来，形成一个双滚道外圈，再将两套内组件按照装配的要求，装入外圈内，两内组件用弹簧卡圈连接固定，防止两内组件分离。最后，进行注脂，在两侧装入第一密封圈和第二密封圈及防尘盖，形成成品。 
本实用新型的有益效果：外圈采用两体式结构，普通的设备就可以磨削加工，砂轮轴无需太长，磨削难度相对降低；同样，在磨削两侧密封圈牙口时，难度也降低了很多；在使用方面，外圈两体结构对轴的挠度影响的适应性更强。 
附图说明
图1 为一种新型卡车轮毂轴承结构示意图。 
图中：1、第一密封圈，2、外圈，3、保持架，4、尼龙锁紧圈，5、弹簧卡圈，6、内圈，7、滚动体，8、第二密封圈，9、防尘盖。 
具体实施方式
下面结合附图和实施例对本实用新型进行详细说明。 
如图1所示的一种新型卡车轮毂轴承，内圈6、外圈2为两体式结构，采用尼龙锁紧圈4和两外圈2过盈连接，两内圈6用弹簧卡圈5固定连接，滚动体7、内圈6、保持架3组成组件，与两外圈2组合，两侧分别装上第一密封圈1和第二密封圈8，第二密封圈8外面安装防尘盖9。 
所述新型卡车轮毂轴承的装配过程如下：将滚动体7放入到保持架3的兜孔中，然后放入内圈6，形成保持架3、滚动体7、内圈6的内组件，然后利用尼龙锁紧圈4将两个单外圈2连接起来，形成一个双滚道外圈，再将两套内组件按照装配的要求，装入外圈2内，两内组件用弹簧卡圈5连接固定，防止两内组件分离，最后，进行注脂，在两侧装入第一密封圈1和第二密封圈8及防尘盖9，形成成品。
