Description

一种防滑自清洁双列球轴承
技术领域
本发明属于轴承零件技术领域，具体涉及为一种防滑自清洁双列球轴承。
背景技术
根据汽车型号的不同，在汽车发动机惰轮上，有的选用双列深沟球轴承作为涨紧轮轴承，对于该轴承所能承受的径向负荷要求较大，一般可达到 1100N 左右，故对该轴承的设计，除了要选择优质原材料与工艺外，轴承的密封性是十分重要，现有技术中深沟球轴承的外圈的内壁端面附近设有密封槽，密封圈嵌设在所述的密封槽内，但是，这种结构的深沟球轴承，密封圈嵌入后密封效果差，极容易产生漏脂，润滑脂的使用寿命难以满足要求。
另外，在皮带传动、链条传动、钢丝传动等机械传动中，为了避免皮带、链条钢丝绳等传动元件的松动，往往需要在这些传动元件上支撑张紧轮，用以维持它们具有要求的张力来保证传动的正常进行。但是传统的轴承容易打滑，难以保证工件的稳定运行。
发明内容
本发明的目的在于克服上述提到的缺陷和不足，而提供一种防滑自清洁双列球轴承。
本发明实现其目的采用的技术方案如下。
一种防滑自清洁双列球轴承，包括外圈、内圈、钢球、保持架和密封件；所述外圈内表面、内圈外表面均设有双排环形沟道，在沟道内设有钢球，在钢球两侧设有保持架；所述保持架有两个，每个保持架背部设有开口的窗孔，且开口的窗孔具有自锁量；所述内圈内壁开设有嵌槽；所述嵌槽分设于双排环形沟道两侧；所述密封件外端固定于外圈内壁，内端嵌入嵌槽，并与嵌槽外壁间隙设置；所述外圈外壁的中部设有一环内沟槽，所述内沟槽和外圈同轴设置；所述外圈外壁两侧设置有间隔且平行设置的侧排槽，所述内沟槽与侧排槽导通；所述内沟槽与侧排槽的交角为45°。
所述密封件内端设置有第一凸起、第二凸起和第三凸起；所述第二凸起位于第一凸起和第三凸起中间；所述第一凸起与嵌槽外壁存在0.1~0.15mm的间隙；所述第二凸起与嵌槽外壁存在0.08~0.1mm的间隙；所述第三凸起与嵌槽外壁存在0.1~0.15mm的间隙。
本轴承在外壁设置内沟槽与侧排槽，提高了齿轮外壁的摩擦系数，并且，当齿轮和皮带之间窜入微粒杂质时，微粒杂质容易积聚在内沟槽中，并且在皮带的带引下，通过侧排槽外排，起到自清洁的效果。
本双列球轴承，采用分体开口式保持架，解决了由于内部空间限制，无法使用分体式保持架的瓶颈，并且大大提高了保持架的强度；并使得两列钢球之间始终保持相对均匀分布，提高了载荷的均衡，避免应力集中，保持两列钢球在合理的距离工作，从而大大提高了轴承可靠性和寿命。另外，本双列球轴承采用密封件，提高了轴承内圈、轴承外圈的密封程度和强度，确保了机械传动机构长时间有效的运行。

具体实施方式
下面结合附图，对本发明作进一步详细说明。
一种防滑自清洁双列球轴承，，包括外圈1、内圈2、钢球3、保持架4和密封件5；所述外圈1内表面、内圈2外表面均设有双排环形沟道，在沟道内设有钢球3，在钢球3两侧设有保持架4；所述保持架4有两个，每个保持架4背部设有开口的窗孔，且开口的窗孔具有自锁量；所述内圈2内壁开设有嵌槽2a；所述嵌槽2a分设于双排环形沟道两侧；所述密封件5外端固定于外圈1内壁，内端嵌入嵌槽2a，并与嵌槽2a外壁间隙设置。
所述外圈1外壁的中部设有一环内沟槽1a，所述内沟槽1a和外圈1同轴设置；所述外圈1外壁两侧设置有间隔且平行设置的侧排槽1b，所述内沟槽1a与侧排槽1b导通；所述内沟槽1a与侧排槽1b的交角为45°。
本轴承在外壁设置内沟槽与侧排槽，提高了齿轮外壁的摩擦系数，避免打滑，保证工件的稳定运行；并且，当齿轮和皮带之间窜入微粒杂质时，微粒杂质容易积聚在内沟槽中，并且在皮带的带引下，通过侧排槽外排，起到自清洁的效果。
本双列球轴承，采用分体开口式保持架，解决了由于内部空间限制，无法使用分体式保持架的瓶颈，并且大大提高了保持架的强度；并使得两列钢球之间始终保持相对均匀分布，提高了载荷的均衡，避免应力集中，保持两列钢球在合理的距离工作，从而大大提高了轴承可靠性和寿命。
所述密封件5内端设置有第一凸起5a、第二凸起5b和第三凸起5c；所述第二凸起5b位于第一凸起5a和第三凸起5c中间；所述第一凸起5a与嵌槽2a外壁存在0.1~0.15mm的间隙；所述第二凸起5b与嵌槽2a外壁存在0.08~0.1mm的间隙；所述第三凸起5c与嵌槽2a外壁存在0.1~0.15mm的间隙。
第一凸起5a可以储存轴承内多余的油脂，阻碍油脂外溢；第二凸起5b起到密封作用；第三凸起5c防止外部灰尘侵入，由于形成较长的曲路密封通道，使轴承的密封效果达到最佳程度。
因此，本轴承具有良好密封性，密封件5对内圈2无摩擦损伤，便于安装拆卸。
本发明按照实施例进行了说明，在不脱离本原理的前提下，本装置还可以作出若干变形和改进。应当指出，凡采用等同替换或等效变换等方式所获得的技术方案，均落在本发明的保护范围内。
