Description

一种带弹性垫片的冲压外圈角接触球轴承
技术领域
本发明涉及一种轴承,特别涉及一种带弹性垫片的冲压外圈角接触球轴承。
背景技术
冲压外圈角接触球轴承目前已在转向管柱上广泛应用,其管柱的上下端各装一个,因管柱结构、长度、上下座孔的误差等原因,此类轴承采用松散型结构。在装配过程中需要消除轴承的轴向间隙,并固定好轴的位置保证不松动。为防止在装配中的误差造成轴承抱死产生的问题,一般在轴承上加弹簧,此类方法增加了轴向方向的尺寸和装配成本。
发明内容
本发明提供了一种带弹性垫片的冲压外圈角接触球轴承,可取消轴向方向上安装的弹簧,可减小占用空间,降低成本。
本发明的工作原理:一种带弹性垫片的冲压外圈角接触球轴承,包括外圈和内圈;所述内圈设置于外圈内侧;所述外圈内侧上设置有滚道;所述滚道上设置有钢球;所述滚道上还设置有保持架;所述保持架将钢球位置固定;所述钢球与内圈接触;所述内圈内侧设置有内衬套;所述内衬套上设置有弹性垫片;所述内衬套上设置有内衬勾爪;所述内衬勾爪勾在外圈端面上;所述内衬套远离内衬勾爪的一端设置有弹性垫片。角接触球轴承与常规轴承不同,其在自由状态下,各零件是松散型组合,由内衬套上的勾爪勾在外圈的端面上,使所有零件相对固定在外圈和内衬套之间。
进一步的是:所述内衬套与内圈接触部位为斜面,当内衬套受到轴向载荷时,一方面传递轴向力使得钢球和内外滚道接触达到轴承的功能,另一方面径向分力促使内衬套的内径缩小与工作轴抱紧使得内衬套、内圈、钢球、保持架一起随工作轴的转动而工作。
进一步的是:所述内衬套上设置内衬勾爪的一端伸出外圈。
进一步的是:所述内衬勾爪轴向上与外圈端面之间留有2mm间隙。
进一步的是:所述弹性垫片上设置有多个弹片勾爪;多个所述弹片勾爪勾在内衬套上。
本发明的有益效果为:本技术方案中的结构解决了产品装配中需要增加弹簧的来防止装配误差的问题,在控制成本的前提下缩短了管柱轴尺寸、取消弹簧,降低了客户的成本。
增加了弹性垫片取代传统的弹簧,可节省安装弹簧的空间,使得冲压外圈角接触球轴承在具有轴向弹性功能的同时,实现产品在有限的空间下的应用,在现有产品中取消弹簧后降低了生产成本,提高产品的竞争力。

具体实施方式
为了加深对本发明的理解,下面将结合附图和实施例对本发明做进一步详细描述,该实施例仅用于解释本发明,并不对本发明的保护范围构成限定。
如图1和图2所示,一种带弹性垫片的冲压外圈角接触球轴承,包括外圈1和内圈2;所述内圈2设置于外圈1内侧;所述外圈1内侧上设置有滚道;所述滚道上设置有钢球3;所述滚道上还设置有保持架4;所述保持架4将钢球3位置固定;所述钢球3与内圈2接触;所述内圈2内侧设置有内衬套5;所述内衬套5上设置有弹性垫片6;所述内衬套5上设置有内衬勾爪51;所述内衬勾爪51勾在外圈1端面上;内衬套5外径上刻有沟槽,所述弹性垫片6上设置有多个弹片勾爪61;多个所述弹片勾爪61勾在内衬套5的沟槽内。角接触球轴承与常规轴承不同,其在自由状态下,各零件是松散型组合,由内衬套5上的内衬勾爪51勾在外圈1上,使所有零件相对固定在外圈1和内衬套5之间。
在上述基础上,所述内衬套5上设置内衬勾爪51的一端伸出外圈1;所述内衬勾爪51轴向上与外圈1端面之间留有2mm间隙。
在上述基础上,所述内衬套5与内圈2接触部位为斜面,所述的内衬套5其斜面与内圈2的圆弧面接触,实际工作中,当内衬套2受到轴向载荷时,一方面传递轴向力使得钢球3和内外滚道接触达到轴承的功能,另一方面径向分力促使内衬套5的内径缩小与工作轴抱紧使得内衬套5、内圈2、钢球3、保持架4一起随工作轴的转动而工作。
上述实施例不应以任何方式限制本发明,凡采用等同替换或等效转换的方式获得的技术方案均落在本发明的保护范围内。
