Description

非标四点接触外球面球轴承
技术领域:
本发明涉及一种轴承,尤其是一种非标四点接触外球面球轴承。
背景技术:
现有的四点接触球轴承,一般包括外圈、内圈、设于内外圈之间的若干个钢球和保持架。其通常应用于空间受限,但又对双向负荷或承载能力有更高要求的场合,接触角通常为35°。因现有四点接触球轴承的外圈外表面截面形状为平面,在与轴承座结合应用时,如果安装轴倾斜度偏大或存在长轴挠度、弯曲时,会产生较大轴向力或倾覆力矩,而导致轴承快速损毁。
发明内容:
为克服现有四点接触球轴承在与轴承座结合应用时,如果安装轴倾斜度偏大或存在长轴挠度、弯曲时,会产生较大轴向力或倾覆力矩,而导致轴承快速损毁的问题,本发明实施例提供了一种非标四点接触外球面球轴承。
非标四点接触外球面球轴承,其至少包括外圈、内圈、以及设于外圈和内圈之间的钢球,钢球与内、外圈环形沟道的接触点的连线与轴承径向平面之间形成第一接触角a1和第二接触角a2,外圈的外表面为外球面。
本发明实施例,既可承受径向载荷,也可承受轴向载荷,或者同时承受径向和轴向的联合载荷,并具有更高的载荷能力,同时还可承受更高的倾覆力矩,将外圈的外表面设计成外球面,在与带内球面安装孔的轴承座相结合应用时,即使受到倾覆力矩,也可通过其外圈的外球面与轴承座安装孔的内球面进行自动调心校正,从而延长轴承产品的使用寿命。
附图说明:
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本发明实施例的非标四点接触外球面球轴承的结构示意图;
图2为本发明实施例的轴承座的结构示意图;
图3为图2的A-A向剖视图。
具体实施方式:
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
如图1所示,非标四点接触外球面球轴承,其至少包括外圈1、内圈2、以及设于外圈1和内圈2之间的钢球3,钢球3与内、外圈环形沟道的接触点的连线与轴承径向平面之间形成第一接触角a1和第二接触角a2,外圈1的外表面为外球面。
本发明实施例,既可承受径向载荷,也可承受轴向载荷,或者同时承受径向和轴向的联合载荷,并具有更高的载荷能力,同时还可承受更高的倾覆力矩,将外圈的外表面设计成外球面,在与带内球面安装孔的轴承座相结合应用时,即使受到倾覆力矩,也可通过其外圈的外球面与轴承座安装孔的内球面进行自动调心校正,从而延长轴承产品的使用寿命。
