Abstract

本发明公开了一种基于外圈设置圆弧油槽的双列圆锥滚子轴承，两个内圈02中部由内隔圈63隔置，两个内圈02和外圈21之间分别通过保持架设置有圆锥滚子04；保持架包括保持架大垫圈06和保持架小垫圈16，以及保持架支柱09。所述外圈中部开设有绕外圈一周的环形槽，所述环形槽为弧形槽，所述槽底开设有通向所述保持架和滚子的润油孔。本发明把油槽改成弧形后，油槽与轴承外圈连接点均匀平滑，这样润滑油可以很好的全部利用上，这样可以延长轴承使用的使用寿命，减少维修次数，缩短维修时间。而且其弧形油槽光洁度高，延长了润滑油的填加周期，使用成本降低，润滑速度提高。加工时一次成形，提高了轴承生产效率，降低成本了生产成本。

Description

基于外圈设置圆弧油槽的双列圆锥滚子轴承
技术领域
本发明涉及轴承技术领域。
背景技术
如图1所示，现有技术双列圆锥轴承的结构包括外圈21、内圈02，两个内圈02中部由内隔圈63隔置，两个所述内圈02和外圈21之间分别通过保持架设置有圆锥滚子04。其中，保持架包括保持架大垫圈06和保持架小垫圈16，以及保持架支柱09。
如图1中A处所示，现有技术双列圆锥滚子轴承油槽的形式为梯形槽，槽底设置有通向保持架和滚子的润有孔。问题在于。该形状的油槽在工作的时，润滑油脂不容易流入，而且润滑油添加的周期短，这样很容易导致轴承在旋转时得不到很好保护，增加维护次数，降低轴承的寿命。而且这样的油槽在生产的时候比较费劲，加大轴承成本，而且效率也低。
发明内容
本发明旨在提供一种润滑效果好的双列圆锥轴承。
为了达到上述目的，本发明提供一种基于外圈设置圆弧油槽的双列圆锥滚子轴承，包括外圈、内圈。两个内圈中部由内隔圈隔置，两个所述内圈和外圈之间分别通过保持架设置有圆锥滚子；所述保持架包括保持架大垫圈和保持架小垫圈，以及保持架支柱；所述外圈中部开设有绕外圈一周的环形槽，所述环形槽为弧形槽，所述槽底开设有通向所述保持架和滚子的润油孔。
本发明把油槽改成弧形后，油槽与轴承外圈连接点均匀平滑，这样润滑油可以很好的全部利用上，这样可以延长轴承使用的使用寿命，减少维修次数，缩短维修时间。而且其弧形油槽光洁度高，延长了润滑油的填加周期，使用成本降低，润滑速度提高。加工时一次成形，提高了轴承生产效率，降低成本了生产成本。
附图说明
图1是现有技术双列圆锥轴承的结构示意图。
图2是本发明双列圆锥轴承的结构示意图。
具体实施方式
如图2所示本发明基于外圈设置圆弧油槽的双列圆锥滚子轴承，包括外圈21、内圈02，两个内圈02中部由内隔圈63隔置，两个所述内圈02和外圈21之间分别通过保持架设置有圆锥滚子04；所述保持架包括保持架大垫圈06和保持架小垫圈16，以及保持架支柱09。图中B处所示，外圈中部开设有绕外圈一周的环形槽，所述环形槽为弧形槽，所述槽底开设有通向所述保持架和滚子的润油孔。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
