Description

一种双列调心滚子轴承
技术领域
本发明涉及一种滚子轴承,具体地说是一种专用于柴油泵上的双列调心滚子轴承。
背景技术
在已有技术中,调心滚子轴承主要采用在二片铁保持架中间装有中挡圈,在保持架中挡圈内装有滚子。该种结构的调心滚子轴承装配较困难,耐磨性差,散热性能差,强度抵,使用寿命短。
发明内容
本发明的目的是提供一种双列调心滚子轴承,解决现有技术调心滚子轴承装配困难、耐磨性差、散热性能差、强度低以及使用寿命短的问题。
本发明的目的是通过以下技术方案来实现:
一种双列调心滚子轴承,包括轴承外圈、轴承内圈,在轴承外圈和轴承内圈之间安装双列滚子,所述双列滚子对称布置;轴承外圈的内壁为球面,滚子的表面弧度与球面的弧度相同,对应双列滚子在轴承内圈设有双列滚子轨道,所述轨道配合滚子表面的弧度;在轴承内圈的外部套有保持架,所述保持架整体成型。
本发明结构简单、紧凑,合理,制造成本低;由于采用了整体式黄铜保持架,对称型加强滚子,能适用于机械精度较高条件下使用;其耐磨性、散热性较好;轴承旋转灵活,强度高,能延长使用寿命,经过1000小时满负荷运转寿命的试验,完全能达到油泵的使用要求和各项技术指标。
附图说明
下面根据附图和实施例对本发明作进一步详细说明。
图1是双列调心滚子轴承的结构图。
图中:
1、轴承外圈;2、轴承内圈;3、滚子;4、滚子轨道;5、保持架。
具体实施方式
如图1所示,本发明所述的一种双列调心滚子轴承,包括轴承外圈1、轴承内圈2,在轴承外圈1和轴承内圈2之间安装双列滚子3,所述双列滚子3对称布置;轴承外圈1的内壁为球面,滚子3的表面弧度与球面的弧度相同,对应双列滚子3在轴承内圈2设有双列滚子轨道4,所述轨道4配合滚子3表面的弧度;在轴承内圈2的外部套有保持架5,所述保持架5整体成型。
保持架5采用黄铜材料加工成整体式套在轴承内圈2上并固定。轴承外圈1经过保护气氛热处理,从而能提高轴承的耐磨性,延长轴承的使用寿命,经过寿命试验,为柴油泵的国产化,开辟了新路,并能降低柴油泵的生产成本。
由于轴承外圈1的内壁为球面,双列滚子3可以在球面的内部自由转动,这样在轴承所支撑的转轴在受到震动的时候,即使产生微小偏转,那么也可以使双列滚子在轴承外圈1的内壁上正常转动,不会带来局部受到大应力而损坏的问题。
本发明结构简单、紧凑,合理,制造成本低;由于采用了整体式黄铜保持架,对称型加强滚子,能适用于机械精度较高条件下使用;其耐磨性、散热性较好;轴承旋转灵活,强度高,能延长使用寿命,经过1000小时满负荷运转寿命的试验,完全能达到油泵的使用要求和各项技术指标。
