Description

轴承组件、轴承组件安装结构及吹风装置 技术领域
本发明涉及家用电器技术领域，具体涉及一种轴承组件、轴承组件安装结构及吹风装置。
背景技术
塔扇是目前市场上的一种新型风扇，由于其独特的柱式造型且使用过程中占地面积较小，受到大多消费者的青睐。由于塔扇瘦高的特点，其风叶只能选用贯流风叶，依靠电机带动而产生风力，故贯流风叶是塔扇必不可少的一个零件。在整机装配时，贯流风叶的一侧与电机联接，另一侧靠风叶轴承固定在壳体上。
风叶轴承组件包括风叶轴承和风叶轴承套。目前市场上的风叶轴承组件整体呈圆柱状，风叶轴承的外圆柱面在装入风叶轴承套后与风叶轴承套的内圆柱面接触配合，两个圆柱面如果不平齐则会导致风叶轴承组件在工作时发生振动。因此对两个圆柱面的加工精度要求较高。

本发明的优点：
1、本发明提供的轴承组件，通过在轴承套的内装配面和/或外装配面上设置朝向对面装配面突出且与对面装配面接触配合的支撑结构，使得由现有技术中的轴承套和轴承的两个装配面的配合变成了支撑结构与对面装配面的配合，该种设置避免了轴承装入轴承套后两个装配面不平齐带来的振动，对轴承和轴承套的两个装配面的加工精度要求也降低；同时，本发明轴承组件的支撑结构在所处装配面的圆周方向上对称设置，该种设置能够保证轴承与轴承套的中心一致。
2、本发明提供的轴承组件，其支撑结构包括在轴承的外装配面上加工若干筋条，从加工工艺角度考虑，在轴承的外装配面上加工筋条，相比在轴承套的内装配面上加工筋条，加工难度要小很多，生产成本也要低很多。
3、本发明提供的轴承组件，通过在若干筋条的前端设置倒角，使得筋条变成楔形筋条，该种设置对筋条的装配起到导向作用，方便轴承装入轴承套内部。
4、本发明提供的轴承组件，通过在其轴向限位结构的凸段上设有朝向 其槽段突出且与对面槽段的表面接触配合的支撑凸台，以使凸段表面与槽段表面之间形成空隙，该种设置减少了凸段表面与槽段表面的接触面积，避免了凸段表面与槽段表面由于加工精度问题而导致的不平齐的问题。
5、本发明提供的轴承组件安装结构，通过在壳体上设置轴承座和第一卡扣，在轴承组件上设置第二卡扣，使得在装配轴承组件时通过第一卡扣和第二卡扣形成卡扣结构以实现轴承组件的固定，省去了打螺钉工序，提供了生产效率；此外，本发明提供的轴承组件安装结构，其第一卡扣和轴承座与壳体一体成型，在装配时无需单独装配轴承座，节省了装配步骤，进一步提高了生产效率，而且无需单独制作轴承座的模具，降低了生产成本。
6、本发明提供的轴承组件安装结构，通过在轴承组件上设置朝向轴承座延伸的第一延伸臂和第二延伸臂，使得当轴承组件装入轴承座时，第一延伸臂和第二延伸臂同时位于形成轴承座的第一支撑壁和第二支撑壁的外侧或者内侧，且第一延伸臂和第二延伸臂分别与对应的第一支撑壁和第二支撑壁相贴合，防止了轴承组件在装入轴承座后在左右方向上发生晃动。
7、本发明提供的轴承组件安装结构，通过在第一卡扣和第二卡扣至少之一上设置用于引导两者形成卡扣结构的引导斜面，使得轴承组件在装入轴承座时第一卡扣和第二卡扣更容易形成卡扣配合，提高了装配效率。
8、本发明提供的轴承组件安装结构，通过将第一卡扣和第二卡扣至少之一设置为弹性卡扣，使得轴承组件在装入轴承座时，第一卡扣和/或第二卡扣在装配时发生弹性变形，这样一方面方便第一卡扣和第二卡扣形成卡扣配合，另一方面是变形后的卡扣通过变形的弹性力能够使得卡扣结构配合更紧固。

具体实施方式
下面将结合附图对本发明的实施例进行详细描述。
实施例一
图1示出了本实施例的轴承组件的结构示意图；图2示出了实施例一的轴承组件的剖视图；图3示出了实施例一的轴承组件的轴承套的剖视图；图4示出了实施例一的轴承组件的轴承的结构示意图；如图1至图4所示，本实施例提供一种轴承组件，用在塔扇的贯流风叶上，该轴承组件包括具有内装配面251的轴承套25以及具有外装配面261的轴承26，轴承26从轴承套25的轴向一侧装入轴承套25内部。为了避免轴承26的外装配面261在装入轴承套25之后与轴承套的内装配面251不平齐而导致塔扇在工作时发生振动的问题，在本实施例中，通过在轴承26的外装配面261上设置朝向对面的内装配面251突出的支撑结构，支撑结构在轴承26装入轴承套25之后与对面的内装配面251接触配合。通过该种设置避免了轴承装入轴承套后两个装配面不平齐带来的振动，对轴承和轴承套的两个装配面的加工精度要求也降低；同时，本实施例的轴承组件的支撑结构在所处装配面的圆周方向上对称设置，该种设置能够保证轴承与轴承套的中心一致。
在本实施例中，外装配面261和内装配面251均为圆柱面。
作为支撑结构的一种具体实施例，如图4所示，支撑结构包括在轴承 26的外装配面261的圆周方向设置的若干筋条33。每一筋条33都沿着轴承26的轴向延伸。为了给筋条33的加工以及装配提供便利，若干筋条33在外装配面261的圆周方向上均匀间隔布置。若干筋条33通过车制方式成型。
为了提高轴承26与轴承套25的装配效率，若干筋条33在轴承26的装入方向上的前端设置第一倒角331，该第一倒角331起到了导向的作用。需要说明的是，本实施例中轴承从轴承套的轴向一侧的开口装入轴承套内部，该装入方向指的就是轴承从轴承套的外部到内部的方向。若干筋条33的前端也就是随着轴承先进入轴承套内部的一端。
为了防止轴承26装入轴承套25之后两者在轴向方向发生相对移动，如图2所示，在轴承套与轴承之间设有用于限制装配后的轴承套和轴承在轴向发生相对移动的轴向限位结构，优选的，轴向限位结构在轴承装入方向上位于支撑结构前侧。
轴向限位结构包括成型于内装配面251的凸段2511，以及成型于外装配面261的槽段2611，凸段2511在轴承装入轴承套后与槽段2611形成卡接配合。通过凸段2511和槽段2611的卡接配合能够防止轴承26和轴承套25在轴向方向发生相对移动。
从图3中可以看出，通过凸段2511的设置，使得轴承套的内装配面251变成了多级阶梯状结构；通过槽段2611的设置，使得轴承26的外装配面261变成了三段式结构。该多级阶梯状结构在轴承26装入轴承套25之后与轴承26的三段式结构适配。筋条33设置在轴承的三段式结构的末段上。
为了减少凸段2511的表面与槽段2611的表面的接触面积，如图2所示，本实施例的凸段2511设有朝向槽段2611突出且与对面槽段2611的表面接触配合的支撑凸台2511a，在轴承26装入轴承套25之后，支撑凸台2511a支撑在轴承的槽段2611的表面上，使得凸段2511的表面与槽段2611表面之间形成空隙35。该种设置减少了凸段2511表面与槽段2611表面的接触面积，避免了凸段2511表面与槽段2611表面由于加工精度问题而导致的不平齐的问题。
同时，在本实施例中，为了方便轴承26的装配，在轴承26的前端设有第二倒角262。
作为本发明的优选实施例，轴承26的槽段2611邻近在第一倒角331的后侧，在装配轴承时，轴承的前端通过第一倒角331从轴承套25的前端的开口伸出，第一倒角331后侧的槽段2611侧壁倒扣在轴承套25的前端面上。
作为上述支撑结构的一种可替换方式，支撑结构还可以设置在轴承套的内装配面251上。
作为上述支撑结构的一种可替换方式，支撑结构还可以设置在轴承套25的内装配面251和轴承26的外装配面261上。例如支撑结构为若干筋条33，其中部分筋条33成型在轴承套25的内装配面251上，部分筋条33成型在轴承26的外装配面261上，轴承套25上的筋条33与轴承26的筋条33错开设置，分别与对面的装配面接触配合。
作为上述支撑结构的一种可替换方式，支撑结构还可以为成型在所处装配面上的若干圆形凸起。
最后需要说明的是，本实施例的轴承组件不限于用在塔扇的贯流风叶上。
实施例二
图1示出了本实施例的轴承组件2的结构示意图；图5示出了本实施例轴承组件2与壳体1的装配图示意图。如图1和图5所示，本实施例提供一种用于吹风装置的轴承组件安装结构，轴承组件安装结构包括壳体1和实施例一的轴承组件2。轴承组件2包括轴承套25和轴承26，轴承26可拆卸地安装于轴承套25内。轴承组件2为与贯流风叶的风叶轴配合的轴承组件2。壳体1上设有轴承座11和第一卡扣12，轴承座11、第一卡扣12及壳体1一体成型；轴承组件2设有第二卡扣21，第二卡扣21在轴承组件2装配至轴承座11时与第一卡扣12配合形成锁紧轴承组件2的卡扣结构。通过在壳体1上设置轴承座11和第一卡扣12，在轴承组件2上设置第二卡扣21，使得在装配轴承组件2时通过第一卡扣12和第二卡扣21形 成卡扣结构以实现轴承组件2的固定，省去了打螺钉工序，提供了生产效率；此外，本实施例提供的轴承组件安装结构，其第一卡扣12和轴承座11与壳体1一体成型，在装配时无需单独装配轴承座11，节省了装配步骤，进一步提高了生产效率，而且无需单独制作轴承座11的模具，降低了生产成本。
进一步的，在本实施例中，轴承组件2沿着设定插入方向装入轴承座11，设定插入方向根据轴承组件安装结构实际的装配状态可以进行调整。在本实施例中，如图2所示，设定插入方向指的是自上而下的竖直方向。在其他实施例中，根据实际应用情况的不同，插入方向也会有所不同，例如可以是自下而上，还可以是从前至后或者从后至前。
如图1和图5所示，第一卡扣12设置在轴承座11的下方，轴承组件2的下方成型有朝向轴承座11延伸的延伸臂，延伸臂上的底端成型有第二卡扣21。轴承组件2自上而下装入轴承座11时，延伸臂伸入到轴承座11的下方，直至第二卡扣21与第一卡扣12配合形成卡扣结构。
在本实施例中，如图1和图5所示，壳体1上成型有平行且间隔设置的第一支撑壁13和第二支撑壁14，轴承座11形成于第一支撑壁13和第二支撑壁14的对应一端。第一支撑壁13和第二支撑壁14相对应的内壁上分别成型有第二卡扣21；延伸臂包括设于轴承组件2轴向两端的第一延伸臂22和第二延伸臂23，第一延伸臂22和第二延伸臂23上成型有第二卡扣21。第一延伸臂22和第二延伸臂23位于第一支撑壁13和第二支撑壁14的内侧或外侧且与第一支撑壁13和第二支撑壁14的对应内壁或外壁相贴合。通过在轴承组件2上设置朝向轴承座11延伸的第一延伸臂22和第二延伸臂23，使得当轴承组件2装入轴承座11时，第一延伸臂22和第二延伸臂23同时位于形成轴承座11的第一支撑壁13和第二支撑壁14的外侧或者内侧，且第一延伸臂22和第二延伸臂23分别与对应的第一支撑壁13和第二支撑壁14相贴合，防止了轴承组件2在装入轴承座11后在左右方向上发生晃动。
此外，为了方便轴承组件2与轴承座11的装配，在第一卡扣12和第 二卡扣21上设有用于引导两者形成卡扣结构的引导斜面24。通过引导斜面24使得轴承组件2在装入轴承座11时第一卡扣12和第二卡扣21更容易形成卡扣配合，提高了装配效率。
具体地，如图5，壳体1的第一支撑壁13上的第一卡扣12为第一卡槽，第二支撑壁14上的第一卡扣12为第一卡凸，轴承组件2的第一延伸臂22的底端的第二卡扣21为第二卡凸，第二延伸臂23的底端的第二卡扣21为第二卡槽。在装配时，轴承组件2自上而下装配到轴承座11上，轴承组件2的第一延伸臂22和第二延伸臂23伸入到第一支撑壁13和第二支撑壁14的内侧并分别与第一支撑壁13和第二支撑壁14的内侧壁贴合，第一延伸臂22底端的第二卡凸和第二延伸臂23底端的第二卡槽同时与对应的第一支撑壁13上的第一卡槽和第二支撑壁14上的第二卡凸形成卡扣结构。为了进一步方便装配以及卡扣结构的牢固性，第一延伸臂22和第二延伸臂23底端的第二卡扣21结构为弹性卡扣，装配时通过弹性变形卡接至第一支撑壁13和第二支撑壁14的第一卡扣12上。

虽然结合附图描述了本发明的实施方式，但是本领域技术人员可以在不脱离本发明的精神和范围的情况下作出各种修改和变型，这样的修改和变型均落入由所附权利要求所限定的范围之内。
