Description
技术领域technical field
本发明涉及一种复合式轴承结构,特别是一种具有阻流件的复合式轴承结构。The invention relates to a composite bearing structure, in particular to a composite bearing structure with a flow blocking member.
背景技术Background technique
在机械结构中,常利用转动元件来传递动力或改变外形。为了使元件顺利转动,大多会利用轴承结构来承托转动元件,并在轴承结构与转动元件之间注入润滑油,以减少转动元件在轴承结构内转动时所产生的摩擦力。In mechanical structures, rotating elements are often used to transmit power or change the shape. In order to make the components rotate smoothly, most of the bearing structures are used to support the rotating components, and lubricating oil is injected between the bearing structure and the rotating components to reduce the frictional force generated when the rotating components rotate in the bearing structure.
然而,转动元件在运作时与轴承结构之间的摩擦力会转化成热能,润滑油一旦受热后便会增加其流动性,而使得润滑油容易从轴承结构的间隙泄露而出,导致转动元件与轴承结构之间的润滑油容易不足,而无法有效地减少转动元件在轴承结构内转动时所产生的摩擦力。除此之外,为了因应科技发展亦推出了多种小型化的轴承结构。这些小型化的轴承结构因为整体体积变小,所能够内储的润滑油更加少量。已经内储不多的润滑油更容易因受热而增加其流动性,导致更加无法有效地减少转动元件与轴承结构之间的摩擦力,甚至会严重降低转动元件的使用寿命。However, the frictional force between the rotating element and the bearing structure during operation will be converted into heat energy. Once the lubricating oil is heated, its fluidity will increase, and the lubricating oil will easily leak out from the gap of the bearing structure, causing the rotating element and the bearing structure to leak. The lubricating oil between the bearing structures is easily insufficient, and the frictional force generated when the rotating element rotates in the bearing structure cannot be effectively reduced. In addition, in response to technological development, a variety of miniaturized bearing structures have also been introduced. These miniaturized bearing structures can store a smaller amount of lubricating oil because the overall volume becomes smaller. The lubricating oil that has not been stored in the interior is more likely to increase its fluidity due to heat, which makes it less effective to reduce the friction between the rotating element and the bearing structure, and even seriously reduces the service life of the rotating element.

以下将说明有关本发明的一实施例,首先请参阅图1至图3。图1为根据本发明的一实施例所绘示的复合式轴承结构10a的立体示意图。图2为图1的复合式轴承结构10a的分解示意图。图3为图1的复合式轴承结构10a的剖面示意图。An embodiment of the present invention will be described below. First, please refer to FIG. 1 to FIG. 3 . FIG. 1 is a schematic perspective view of a
本实施例的复合式轴承结构10a例如应用于容置诸如马达、冷却风扇、一般电扇与笔电枢转件等机械转动负载零件的轴心(图中未示出)。复合式轴承结构10a包含一轴套100a、一轴承200a以及至少一第一阻流件300a。轴套100a具有一容置空间101a。轴承200a例如为含油轴承并且设置于轴套100a的容置空间101a。轴承200a具有一轴孔201a。轴孔201a可用来容置上述所提到的轴心。轴承200a与轴套100a形成一腔室C。腔室C用来容纳润滑油(图中未示出)并且连通轴孔201a,使得轴孔201a所容置的轴心得以获得润滑效果。第一阻流件300a设置于腔室C且套设于轴承200a。第一阻流件300a可有效地增加腔室C内的润滑油的流动路径长度,通过第一阻流件300a与轴承200a的复合式结构,使得润滑油不易从轴套100a与轴承200a之间的微小间隙(图中未示出)泄露而出。The
具体来说,在本实施例以及本发明的部分实施例中,轴套100a包含一侧墙110a以及一座部120a。侧墙110a立于座部120a且围绕容置空间101a。轴承200a包含一主体部210a以及一侧部220a。侧部220a设置于主体部210a的一端。主体部210a位于轴套100a的座部120a与侧部220a之间。侧部220a紧配设置于轴套100a的侧墙110a。第一阻流件300a套设轴承200a的主体部210a。也就是说,腔室C内的润滑油可藉由紧配设置的侧墙110a以及侧部220a而不易从轴套100a与轴承200a之间的微小间隙泄露而出;此外,当润滑油受热汽化后亦不易于此轴套100a与轴承200a之间的微小间隙逸散而出。值得注意的是,在本实施例以及本发明的部分实施例中,轴承200a的主体部210a与侧部220a系为一体成型的结构,但本发明不以此为限。在部分实施例中,主体部与侧部亦可为两件式的结构。除此之外,在本实施例以及本发明的部分实施例中,第一阻流件300a于外缘处为圆形,但本发明不以此为限。在部分实施例中,第一阻流件亦可于外缘处具有切边,详细容待以下由图11至图12的实施例来进行说明。Specifically, in this embodiment and some embodiments of the present invention, the
在本实施例以及本发明的部分实施例中,更可包含至少一第二阻流件400a。第二阻流件400a设置于腔室C且套设轴承200a的主体部210a。具体来说,第一阻流件300a的数量与第二阻流件400a的数量皆为多个,并且第一阻流件300a与第二阻流件400a彼此交替地设置。如此一来,当复合式轴承结构10a安装在高速运作的轴心时,可藉由第一阻流件300a与第二阻流件400a的分层结构来分散自轴心传来的震动,进而达到吸震的效果。除此之外,第二阻流件400a的外径小于第一阻流件300a的外径。也就是说,在第二阻流件400a的外缘(未另标号)与侧墙110a之间、以及在相邻两个第一阻流件300a之间,会形成一第一小型容油空间sc1,藉此使得润滑油延长停留在第一阻流件300a、第二阻流件400a与侧墙110a之间,达到降低润滑油流动程度的效果,通过第一阻流件300a、第二阻流件400a与轴承200a的复合式结构,进一步使得润滑油不易从轴套100a与轴承200a之间的微小间隙泄露而出。值得注意的是,在本实施例以及本发明的部分实施例中,系优先将第二阻流件400a的其中一者邻近侧部220a设置。如此一来,第一小型容油空间sc1的其中一者亦会邻近侧部220a,而能提供侧部220a与第二阻流件400a之间良好的润滑效果,但本发明不以此为限。在部分实施例中,亦可将第一阻流件的其中一者邻近轴承的侧部设置。In this embodiment and some embodiments of the present invention, at least one second
在本实施例以及本发明的部分实施例中,第一阻流件300a具有至少一第一缺槽301a,而第二阻流件400a具有至少一第二缺槽401a。具体来说,第一阻流件300a例如具有四个方形的第一缺槽301a,且第一缺槽301a位于第一阻流件300a的内缘(未另标号),而第二阻流件400a例如具有四个方形的第二缺槽401a,且第二缺槽401a位于第二阻流件400a的内缘(未另标号),但本发明不以第一缺槽301a与第二缺槽401a的数量、位置或形状为限。在部分实施例中,第一阻流件可具有二个以上的第一缺槽,而第二阻流件可具有二个以上的第二缺槽。在部分实施例中,第一缺槽可位于第一阻流件的外缘,而第二缺槽可位于第二阻流件的外缘。在部分实施例中,第一缺槽与第二缺槽皆可为圆弧形。在本实施例以及本发明的部分实施例中,第一缺槽301a与第二缺槽401a相错位且彼此相连通。如此一来,每一个第一缺槽301a与第二缺槽401a的内壁面与主体部210a之间皆可形成一第二小型容油空间sc2,藉此使得润滑油延长停留在第一阻流件300a、第二阻流件400a与主体部210a之间,达到降低润滑油流动程度的效果,更进一步使得润滑油不易从轴套100a与轴承200a之间的微小间隙泄露而出。除此之外,由于第一缺槽301a与第二缺槽401a能够分别提供第一阻流件300a与第二阻流件400a些许变形的空间,因此有利于将第一阻流件300a与第二阻流件400a装配套设到主体部210a。In this embodiment and some embodiments of the present invention, the
在本实施例以及本发明的部分实施例中,更可包含一防震结构500a。防震结构500a的材质可例如为诸如铜等金属材质。防震结构500a设置于轴套100a的座部120a与主体部210a之间。防震结构500a包含一中心部510a以及一外周部520a。外周部520a围绕中心部510a。中心部510a凸出外周部520a,并且中心部510a在朝向轴套100a的座部120a的一侧具有一凹陷511a。由于在将防震结构500a组装后,凹陷511a会由中心部510a、外周部520a与座部120a所包围而形成一第三小型容油空间sc3。第三小型容油空间sc3可以储纳润滑油,达到降低润滑油流动程度的效果,通过第一阻流件300a、第二阻流件400a、防震结构500a与轴承200a的复合式结构,而更加进一步地使得润滑油不易从轴套100a与轴承200a之间的微小间隙泄露而出;除此之外,第三小型容油空间sc3还能避免来自轴心的震动通过防震结构500a的中心部510a直接传递到轴套100a内的其他零件。In this embodiment and some embodiments of the present invention, an
在本实施例以及本发明的部分实施例中,更可包含一垫片600a。垫片600a例如为耐磨片并且例如以紧密平贴接触的方式设置于防震结构500a与主体部210a之间。垫片600a具有例如为直线的第一边601a以及例如为弧线的第二边602a。第一边601a连接第二边602a。垫片600a在第一边601a处与侧墙110a保持有一定距离,而垫片600a在第二边602a处贴合侧墙110a。如此一来,垫片600a可在第二边602a处将腔室C分割成一第一储油空间C1以及一第二储油空间C2,但在第一边601a处仍保持第一储油空间C1与第二储油空间C2相连通,其中第一阻流件300a位于第一储油空间C1,而防震结构500a位于第二储油空间C2。藉由设置垫片600a,位于第二储油空间C2的润滑油可能会受到垫片600a的阻挡而不易流动到第一储油空间C1,通过第一阻流件300a、第二阻流件400a、防震结构500a、垫片600a与轴承200a的复合式结构,进而再更加进一步地使得润滑油不易从轴套100a与轴承200a之间的微小间隙泄露而出。In this embodiment and some embodiments of the present invention, a

同样地,在上述的实施例中,系由多个第一阻流件300c与第二阻流件400c套设主体部210c,但本发明不以此为限。请参阅图9至图10。图9为根据本发明的又一实施例所绘示的复合式轴承结构10d的分解示意图。图10为图9的复合式轴承结构10d的剖面示意图。以下仅针对本发明的又一实施例与前述的图6至图8的实施例中不同之处进行说明,其余相同之处将被省略。在本实施例以及本发明的部分实施例中,仅有螺旋状结构的第一阻流件300d套设主体部210d。具体来说,第一阻流件300d例如为线圈弹簧并且位于二侧部220d之间。由于第一阻流件300d具有圆形截面且螺旋围绕的线圈(未另标号),在线圈与主体部210d和线圈与侧墙110d之间会形成多个螺旋通道hxd,藉此增加润滑油的流动路径,通过第一阻流件300d与轴承200d的复合式结构,使得润滑油不易从轴套100d与轴承200d之间的微小间隙泄露而出。值得注意的是,本实施例以及本发明的部分实施例系将第一阻流件300d的线圈弹簧完全压缩,但本发明不以此为限。在部分实施例中,第一阻流件的线圈弹簧亦可未被完全压缩,而形成较大的螺旋通道以增加流道空间。或者,在其他部分实施例中,第一阻流件亦可为其他例如为螺旋柱状体等不具有弹性的螺旋状结构。Similarly, in the above-mentioned embodiment, the
在上述图1至图3的实施例中,第一阻流件300a于外缘处为圆形并且于内缘处具有四个方形的第一缺槽301a,且第二阻件流400a于内缘处具有四个方形的第二缺槽401a,但本发明不以此为限。请参阅图11与图12。图11为根据本发明的再另一实施例所绘示的复合式轴承结构10e的分解示意图。图12为图11的复合式轴承结构10e的剖面示意图。以下仅针对本发明的再另一实施例与前述的图6至图8的实施例中不同之处进行说明,其余相同之处将被省略。在本实施例以及本发明的部分实施例中,第一阻流件300e例如具有三个圆弧形的第一缺槽301e,而第二阻流件400e例如具有三个圆弧形的第二缺槽401e。此外,第一阻流件300e于外缘处具有例如为直线的第一边310e以及例如为弧线的第二边320e。第一边310e连接第二边320e。第一边310e与第一缺槽301e在第一阻流件300e的径向方向上相错位;也就是说,第一缺槽301e背向第二边320e。第一边310e至第一阻流件300e的中心点(未另标号)的最短距离小于第二边320e至第一阻流件300e的中心点的最短距离。第一阻流件300e在第一边310e处与侧墙110e保持有一定距离,而第一阻流件300e在第二边320e处贴合侧墙110e。如此一来,第一小型容油空间sc1彼此之间仍可在第一边310e处保有一定的连通性。同理,图6至图8的实施例亦可将第一阻流件300c改成配置为图11至图12的实施例的第一阻流件300e而成为又另一实施例,在此不再加以赘述。In the above embodiments of FIGS. 1 to 3 , the
根据上述实施例所揭露的复合式轴承结构,第一阻流件设置于腔室且套设于轴承。如此一来,第一阻流件可有效地增加腔室内的润滑油的流动路径长度,通过第一阻流件与轴承的复合式结构,使得润滑油不易从轴套与轴承之间的微小间隙泄露而出。According to the composite bearing structure disclosed in the above embodiments, the first flow blocking member is disposed in the chamber and sleeved on the bearing. In this way, the first choke element can effectively increase the length of the flow path of the lubricating oil in the chamber, and through the composite structure of the first choke element and the bearing, the lubricating oil cannot easily escape from the small gap between the bushing and the bearing. leaked out.
在部分实施例中,侧部紧配设置于轴套的侧墙。腔室内的润滑油可藉由紧配设置的侧墙以及侧部而不易从轴套与轴承之间的微小间隙泄露而出;此外,当润滑油受热汽化后亦不易于此轴套与轴承之间的微小间隙逸散而出。In some embodiments, the side portion is tightly fitted to the side wall of the bushing. The lubricating oil in the chamber can not easily leak out from the small gap between the bushing and the bearing due to the tightly fitted side walls and side parts; in addition, when the lubricating oil is heated and vaporized, it is not easy to connect the bushing and the bearing. The tiny gap between them escapes.
在部分实施例中,第一阻流件与第二阻流件彼此交替地设置。如此一来,当复合式轴承结构安装在高速运作的轴心时,可藉由第一阻流件与第二阻流件的分层结构来分散自轴心传来的震动,进而达到吸震的效果。In some embodiments, the first spoiler and the second spoiler are arranged alternately with each other. In this way, when the composite bearing structure is installed on the axis of high-speed operation, the layered structure of the first choke element and the second choke element can disperse the vibration from the axle center, so as to achieve shock absorption. Effect.
在部分实施例中,第二阻流件的外径小于第一阻流件的外径,以形成第一小型容油空间,藉此使得润滑油延长停留在第一阻流件、第二阻流件与侧墙之间,达到降低润滑油流动程度的效果,通过第一阻流件、第二阻流件与轴承的复合式结构,进一步使得润滑油不易从轴套与轴承之间的微小间隙泄露而出。In some embodiments, the outer diameter of the second spoiler is smaller than the outer diameter of the first spoiler, so as to form a first small oil-accommodating space, thereby allowing the lubricating oil to stay in the first spoiler and the second spoiler for an extended period of time. Between the flow piece and the side wall, the effect of reducing the flow of lubricating oil is achieved. Through the composite structure of the first choke piece, the second choke piece and the bearing, it is further difficult for the lubricating oil to escape from the tiny gap between the bushing and the bearing. The gap leaked out.
在部分实施例中,第一缺槽与第二缺槽相错位。如此一来,每一个第一缺槽与第二缺槽的内壁面与主体部之间皆可形成第二小型容油空间,藉此使得润滑油延长停留在第一阻流件、第二阻流件与主体部之间,达到降低润滑油流动程度的效果,更进一步使得润滑油不易从轴套与轴承之间的微小间隙泄露而出。In some embodiments, the first groove and the second groove are displaced. In this way, a second small oil-accommodating space can be formed between the inner wall surface of each of the first groove and the second groove and the main body, so that the lubricating oil can stay in the first blocking member and the second blocking member for an extended period of time. Between the flow piece and the main body, the effect of reducing the flow of the lubricating oil is achieved, and the lubricating oil is further prevented from leaking out from the small gap between the shaft sleeve and the bearing.
在部分实施例中,更可包含防震结构。在将防震结构组装后,凹陷会由中心部、外周部与座部所包围而形成一第三小型容油空间。第三小型容油空间可以储纳润滑油,达到降低润滑油流动程度的效果,通过第一阻流件、第二阻流件、防震结构与轴承的复合式结构,而更加进一步地使得润滑油不易从轴套与轴承之间的微小间隙泄露而出;除此之外,第三小型容油空间还能避免来自轴心的震动通过防震结构的中心部直接传递到轴套内的其他零件。In some embodiments, an anti-vibration structure may be further included. After the anti-vibration structure is assembled, the recess is surrounded by the central portion, the outer peripheral portion and the seat portion to form a third small oil-accommodating space. The third small oil-accommodating space can store lubricating oil to reduce the flow of lubricating oil. Through the composite structure of the first choke element, the second choke element, the shock-proof structure and the bearing, the lubricating oil can be further reduced. It is not easy to leak out from the small gap between the shaft sleeve and the bearing; in addition, the third small oil storage space can prevent the vibration from the shaft center from being directly transmitted to other parts in the shaft sleeve through the central part of the anti-vibration structure.
在部分实施例中,更可包含垫片。藉由设置垫片,位于第二储油空间的润滑油可能会受到垫片的阻挡而不易流动到第一储油空间,通过第一阻流件、第二阻流件、防震结构、垫片与轴承的复合式结构,进而再更加进一步地使得润滑油不易从轴套与轴承之间的微小间隙泄露而出。In some embodiments, spacers may be included. By arranging the gasket, the lubricating oil in the second oil storage space may be blocked by the gasket and cannot easily flow to the first oil storage space. The composite structure with the bearing further makes it difficult for the lubricating oil to leak out from the small gap between the bushing and the bearing.
在部分实施例中,第一阻流件为具有圆形截面且螺旋围绕的线圈,在线圈与主体部和线圈与侧墙之间会形成多个螺旋通道,藉此增加润滑油的流动路径长度,通过第一阻流件与轴承的复合式结构,使得润滑油不易从轴套与轴承之间的微小间隙泄露而出。In some embodiments, the first flow blocking member is a coil with a circular cross-section and is surrounded by a spiral, and a plurality of spiral channels are formed between the coil and the main body and between the coil and the side wall, thereby increasing the flow path length of the lubricating oil , Through the composite structure of the first spoiler and the bearing, the lubricating oil is not easy to leak out from the small gap between the shaft sleeve and the bearing.
在部分实施例中,第一阻流件于外缘处具有第一边以及第二边。第一边连接第二边。第一边与第一缺槽在第一阻流件的径向方向上相错位。第一边至第一阻流件的中心点的最短距离小于第二边至第一阻流件的中心点的最短距离。第一阻流件在第一边处与侧墙保持有一定距离,而第一阻流件在第二边处贴合侧墙。如此一来,第一小型容油空间彼此之间仍可在第一边处保有一定的连通性。In some embodiments, the first baffle has a first edge and a second edge at the outer edge. The first side is connected to the second side. The first side and the first notch are displaced in the radial direction of the first spoiler. The shortest distance from the first side to the center point of the first spoiler is smaller than the shortest distance from the second side to the center point of the first spoiler. The first spoiler is kept at a certain distance from the sidewall at the first side, and the first spoiler is attached to the sidewall at the second side. In this way, the first small oil-accommodating spaces can still maintain a certain degree of connectivity at the first side.
