Description

转子通风机rotor fan

本发明涉及通风机，特别是屋顶(Roof-top)转子通风机。The present invention relates to ventilators, in particular to roof-top rotor ventilators.

本发明主要用作屋顶的通风机而研制的，下文参照本申请将叙述本发明。但要理解的是，本发明不是限定于这种特定的应用领域。The present invention has been developed primarily for use as a ventilator for roofs and will be described hereinafter with reference to this application. It is to be understood, however, that the invention is not limited to this specific field of application.

使用屋顶的转子排气通风机有助于从采用转子通风机的建筑物中排出废气。这些建筑物可以是工厂、农场、库房或家庭住宅。The use of roof-mounted rotor exhaust ventilators helps to extract exhaust air from buildings that employ rotor ventilators. These buildings can be factories, farms, warehouses or family homes.

屋顶的转子通风机的机理是：穿过通风机的空气流动将造成通风机围绕其垂直轴转动，空气流动引起通风机的叶片迫使空气从通风机中出来，导致通风机内部的空气压力低于在流体联通通风机时的建筑物内部的空气压力。因此，建筑物内的空气穿过通风机流动而被排到建筑物的外面。The mechanism of a roof rotor ventilator is that the air flow through the ventilator will cause the ventilator to rotate around its vertical axis, the airflow causes the fan blades to force air out of the ventilator, causing the air pressure inside the ventilator to be lower than The air pressure inside the building when the ventilator is in fluid communication. Thus, the air inside the building flows through the ventilator to be exhausted to the outside of the building.

屋顶的转子通风机的效率取决于多个因素，但主要的是，使通风机转动所需的起始转矩；阻止通风机转动的摩擦量；和叶片的结构。The efficiency of a roof rotor ventilator depends on several factors, but primarily, the starting torque required to turn the ventilator; the amount of friction preventing the ventilator from turning; and the configuration of the blades.

在说明书和权利要求书中，相对转子通风机所使用的术语“上部(upper)”、“上方(above)”和“下部(1ower)”，涉及到通常使用的转子通风机的方位。如将转子通风机在侧向或倒转结构中使用，则它们的方位可以是反向的。因此，“上部”、“上方”和“下部”在这种含义中有较宽地理解，并作为相对的术语。In the description and claims, the terms "upper", "above" and "lower" used with respect to a rotor fan relate to the orientation of a rotor fan in general use. If rotor fans are used in a sideways or inverted configuration, their orientation may be reversed. Accordingly, "upper", "above" and "lower" are to be interpreted broadly in this meaning and as relative terms.

根据本发明的一个方面，提供的转子通风机包括：According to one aspect of the present invention, the provided rotor fan includes:

根据本发明的第二方面，提供了能使转子以一种方式在支承上转动的支承装置，该方式使转子的重心在支承装置下。According to a second aspect of the invention there is provided support means enabling the rotor to rotate on the support in such a way that the center of gravity of the rotor is below the support means.

本发明第二方面的转子最好包括一个平板，该平板有多个从其向下伸延的叶片，其中支承装置适于安装到平板上。另外支承装置最好位于平板上方，并包括一个双支承座圈可转动的支承组件。The rotor of the second aspect of the invention preferably comprises a plate having a plurality of vanes extending downwardly therefrom, wherein the support means is adapted to be mounted to the plate. In addition the support means is preferably located above the plate and comprises a dual support race rotatable support assembly.

The end of each blade has a joint boss for positioning in a corresponding groove of the support.

现在只以举例方式参照下列附图对本发明的最佳实施例进行说明：Preferred embodiments of the present invention will now be described with reference to the following drawings, by way of example only:

图2是图1中去掉拱顶的转子通风机的平面视图；Fig. 2 is a plan view of the rotor ventilator with the dome removed in Fig. 1;

图3是图1转子通风机的横截面侧视图；Fig. 3 is a cross-sectional side view of the rotor fan of Fig. 1;

图5是图4转子通风机的截面侧视图；和Figure 5 is a cross-sectional side view of the rotor ventilator of Figure 4; and

图6是轴承局部剖面侧视图。Fig. 6 is a partial sectional side view of the bearing.

参照附图，其中采用相同标号表示类似的或相同的零件。图1至图3和图6示出了根据本发明的转子通风机的第一最佳实施例，该转子通风机包括机座，机座为中空圆柱形机座件10，其用于安装在屋面、墙壁、天花板、地面等。该机座件10能使空气穿过其开孔11并进入转子通风机的内部12。轴13与该机座件连接并向上伸延。为使该轴增加横向稳定性一般采用一个托架14，并将轴安装到机座件10上。托架14包括下框架撑臂和上框架撑臂。每个框架撑臂15和16的构成，要确保空气流过机座机件10进入转子通风机内部12时基本上不受到阻碍。Referring to the drawings, in which the same reference numerals are used to designate similar or identical parts. Fig. 1 to Fig. 3 and Fig. 6 show the first preferred embodiment of the rotor ventilator according to the present invention, and this rotor ventilator comprises frame, and frame is hollow cylindrical frame part 10, and it is used to be installed on Roofs, walls, ceilings, floors, etc. The frame element 10 allows air to pass through its openings 11 and into the interior 12 of the rotor fan. A shaft 13 is connected to the base member and extends upward. A bracket 14 is generally used to increase the lateral stability of the shaft, and the shaft is mounted on the frame member 10 . Bracket 14 includes lower frame braces and upper frame braces. Each frame brace 15 and 16 is configured to ensure that the flow of air through the frame member 10 into the rotor fan interior 12 is substantially unimpeded.

转子17可绕轴13转动，转子17具有一个平板18和多个从平板向下伸延的叶片19。每个叶片19的一端部20安装到平板18。为了在转子17转动时增加各叶片的稳定性，转子通风机还包括一个环形套筒21形式的安装到各叶片另一端部22的第二平板。Rotor 17 is rotatable about shaft 13 and has a flat plate 18 and a plurality of blades 19 extending downwardly from the flat plate. One end 20 of each blade 19 is mounted to the plate 18 . To increase the stability of the blades when the rotor 17 is rotating, the rotor fan also includes a second plate in the form of an annular sleeve 21 mounted to the other end 22 of each blade.

为使各叶片19安装在平板18和环形套筒21之间，尽管在可替代的实施例中，每个端部20和22可以有不同数量的接头23，但在本实施例中每个叶片19的每个端部20和22有四个凸出接头23。制造叶片19时，接头23与它们相应的叶片19呈平面对准。利用这些凸出接头23把每个叶片的端部20和22安装到对应的平板18和环形套筒21中。为了实现这种安装，平板18和环形套筒21有与凸出接头23相对应的槽。为使叶片19的端部20安装到平板18上，接头23穿过它们在平板18上的对应槽，然后侧向叠合到平板上，处于在图2和图3所示的安装位置。这样就将叶片19的端部20固定到平板18上。同样，为了把叶片19的端部22固定到环形套筒21，端部22上的凸出接头23穿过环形套筒21上的相应穿孔，然后按以类似的方式将接头23叠合到端部20上。这样就将叶片19的端部22固定到环形套筒21上。In order for each vane 19 to fit between the plate 18 and the annular sleeve 21, in this embodiment each vane There are four male tabs 23 at each end 20 and 22 of 19 . When the blades 19 are manufactured, the joints 23 are in planar alignment with their respective blades 19 . These male joints 23 are used to mount the ends 20 and 22 of each blade into the corresponding plate 18 and annular sleeve 21 . To achieve this mounting, the plate 18 and the annular sleeve 21 have grooves corresponding to the male joints 23 . To mount the ends 20 of the blades 19 to the plate 18, the joints 23 pass through their corresponding slots in the plate 18 and are then folded laterally onto the plate in the mounted position shown in FIGS. 2 and 3 . This secures the end 20 of the blade 19 to the plate 18 . Likewise, in order to fix the end 22 of the blade 19 to the annular sleeve 21, the protruding joint 23 on the end 22 passes through the corresponding perforation on the annular sleeve 21, and then the joint 23 is laminated to the end in a similar manner. Part 20 on. This fixes the end 22 of the vane 19 to the annular sleeve 21 .

这种将叶片安装到平板18和环形套筒21的方法无须要求额外的紧固装置。如将叶片19安装到平板18和环形套筒21所需的铆钉或螺钉，从而带来的优点是：减少转子的总重量和减少制造转子通风机的制造时间和成本。This method of mounting the blades to the plate 18 and annular sleeve 21 does not require additional fastening means. Rivets or screws such as are required to mount the blades 19 to the plate 18 and the annular sleeve 21 , thus bringing the advantage of reducing the overall weight of the rotor and reducing the manufacturing time and cost of making the rotor ventilator.

当空气流过转子的叶片19时，叶片19的前缘24会捕捉使转子转动的穿过的空气。在图1至图5所示的本发明实施例的情况下，借助穿过转子通风机的空气流动，使转子按顺时针方向转动。叶片19通过周围空气的运动使转子通风机内部的空气从叶片排出。实现转子通风机内部的空气从叶片排出，是由于尾缘25与转子通风机内部存在的空气相贯穿，迫使空气经叶片19排出转子通风机。这就减少了转子通风机内部12的空气压力。这样，较高压力的空气通过机座件10的开孔11被上排到通风机中，并从转子通风机基本上排出。As air flows over the blades 19 of the rotor, the leading edges 24 of the blades 19 catch the passing air causing the rotor to turn. In the case of the embodiment of the invention shown in Figures 1 to 5, the rotor is caused to rotate in a clockwise direction by the flow of air through the rotor fan. The movement of the vanes 19 by the surrounding air causes the air inside the rotor fan to be expelled from the vanes. Realize that the air inside the rotor fan is discharged from the blades because the trailing edge 25 penetrates the air existing inside the rotor fan, forcing the air to be discharged from the rotor fan through the blades 19 . This reduces the air pressure inside 12 of the rotor fan. In this way, higher pressure air is exhausted upwardly into the fan through the openings 11 of the frame member 10 and substantially exhausted from the rotor fan.

转子通风机还包括轴承装置，该轴承装置为支承结构26的形式，用于支承在轴13上的转子17的转动。该支承结构26一般安装在平板18的顶部，将轴13上的转子17的支承点刚好位于转子17的重心上方，而且使支承结构26仍保持在转子通风机中。The rotor fan also comprises bearing means in the form of a bearing structure 26 for the rotation of the rotor 17 supported on the shaft 13 . The support structure 26 is generally mounted on top of the plate 18, placing the point of support of the rotor 17 on the shaft 13 just above the center of gravity of the rotor 17, and still retaining the support structure 26 in the rotor fan.

在平板18顶部设有支承结构26存在多个优点。支承结构26在平板18上方的位置，就意味着转子17的重心刚好在轴13的支承结构26支承点之下。因此，转子基本上是悬挂在支承结构上的。这就为转子通风机在使用时具有较大稳定性创造了条件，这是因为会减少转子的横向移动。如果支承点低于重心是会发生这种横向移动的。如支承点低于重心，转子将失衡，使支承点形成横向应力。随之而来的是支承结构的工作应力减少。Having the support structure 26 on top of the plate 18 has several advantages. The position of the support structure 26 above the plate 18 means that the center of gravity of the rotor 17 is just below the support point of the support structure 26 of the shaft 13 . Thus, the rotor is essentially suspended from the support structure. This creates the conditions for greater stability of the rotor fan in use, since lateral movement of the rotor is reduced. This lateral movement can occur if the point of support is below the center of gravity. If the support point is lower than the center of gravity, the rotor will be out of balance, causing the support point to form lateral stress. This is followed by a reduction in the operating stresses of the supporting structure.

在平板18顶部具有支承结构26的其它优点是，用转子通风机排出腐蚀气体。因为支承结构是在平板18上方，支承结构就不会与排出气体相接触，这是由于气体是经叶片19在平板18下方排出的。An additional advantage of having the support structure 26 on top of the plate 18 is the removal of corrosive gases with the rotor ventilator. Because the support structure is above the plate 18, the support structure will not come into contact with the exhaust gas as it is discharged below the plate 18 via the vanes 19.

在另一实施例中，支承结构是如此配置的，即确保转子17的重心的位置低于支承结构26。In another embodiment, the support structure is configured such that it ensures that the center of gravity of the rotor 17 is positioned lower than the support structure 26 .

该支承结构包括一个用于固定安装到平板18的配件27。在图2和图3所示的最佳实施例中，该配件27有三个相当长的径向隔开的支承臂28，和三个相当短的径向隔开的支承臂29。这些臂28和29用来将支承结构稳定地固定到平板18上。这些臂一般是铆接到平板18上的，但也可以用焊接或螺钉紧固。The support structure includes a fitting 27 for fixed mounting to the plate 18 . In the preferred embodiment shown in Figures 2 and 3, the fitting 27 has three relatively long radially spaced support arms 28, and three relatively short radially spaced support arms 29. These arms 28 and 29 are used to stably fix the support structure to the plate 18 . These arms are generally riveted to the plate 18, but may be welded or screwed.

支承结构26还包括一个轴承组件，该轴承组件的构成形式为双列座圈滚珠轴承装置30。如图6所示，该双列座圈滚珠轴承装置30包括一个中心轴32，和一个在中心轴32上转动的外套34。该中心轴32和外套34带有相应的滚珠轴承座圈36和38，多个滚珠轴承40在相应的滚珠轴承座圈之间沿轨道运行，以支承该结构。The support structure 26 also includes a bearing assembly in the form of a double row race ball bearing arrangement 30 . As shown in FIG. 6 , the double row race ball bearing device 30 includes a central shaft 32 and a casing 34 rotating on the central shaft 32 . The central shaft 32 and housing 34 carry respective ball bearing races 36 and 38 between which a plurality of ball bearings 40 orbit to support the structure.

双列座圈滚珠轴承装置30中心地固定配置在配件27中，致使中心轴32与平板18的中心轴线呈轴向对准。当双列座圈滚珠轴承装置固定在配件27中时，外套相对于配件27固定，而中心轴32相对于外套34呈自由转动。The double row race ball bearing unit 30 is fixedly arranged centrally in the fitting 27 such that the central axis 32 is axially aligned with the central axis of the plate 18 . When the double-row race ball bearing device is fixed in the fitting 27 , the outer casing is fixed relative to the fitting 27 , while the central shaft 32 is free to rotate relative to the outer casing 34 .

为了能使转子17围绕轴13转动安装，将中心轴32的一端部42安装到轴13的一端部44，致使轴13和32为共轴向对准并固定在一起。To enable the rotor 17 to be mounted for rotation about the shaft 13, one end 42 of the central shaft 32 is mounted to one end 44 of the shaft 13 such that the shafts 13 and 32 are coaxially aligned and fixed together.

转子通风机通常有一个拱顶45，其配置在转子通风机的顶部，以盖住支承结构26和减少转子通风机周围空气流动的阻力。环形套筒21的下侧47一般还安装有一个罩46。也有助于减少转子通风机周围空气流动的阻力。Rotor fans typically have a dome 45 that is disposed on top of the rotor fan to cover the support structure 26 and reduce resistance to air flow around the rotor fan. The underside 47 of the annular sleeve 21 is generally also fitted with a shroud 46 . Also helps reduce resistance to air flow around the rotor ventilator.

上面所叙述的转子通风机的最佳实施例是针对具有直径约为700mm和高度约为460mm的转子通风机。对于这种尺度和较小尺度的通风机，双列座圈滚球轴承装置30通常是需要使用时保持转子17的横向稳定性。只要提供具有一个支承装置的转子通风机，就具有这种尺寸转子通风机的容易制造和降低制造成本的优点，仅要求一个简单的支承装置就能使转子有效而稳定地转动。The preferred embodiment of the rotor fan described above is for a rotor fan having a diameter of about 700 mm and a height of about 460 mm. For fans of this size and smaller, a double row race ball bearing arrangement 30 is usually required to maintain lateral stability of the rotor 17 in use. The advantages of ease of manufacture and reduced manufacturing cost of a rotor fan of this size are provided by providing a rotor fan with only one support means required for efficient and stable rotation of the rotor.

供本发明使用的双列座圈滚珠轴承装置，对于减少转子通风机摩擦转动支承的预防措施来说是不知晓的。在本发明中采用的这类双列座圈滚珠轴承装置是为在潮湿环境下在电机或类似件中使用而研制的，并因此采用高摩擦密封件以确保无水通入到滚球轴承和支承座圈中。一个熟悉相关技术的无创造力的人员，不会认可在如本发明的转子通风机那样的转子通风机应用中，使用这样的双列座圈滚珠轴承装置。The double row race ball bearing arrangement for use in the present invention is unknown with regard to precautions to reduce the frictional rotational bearing of the rotor fan. The type of double row race ball bearing arrangement employed in the present invention was developed for use in electric motors or the like in wet environments, and therefore employs high friction seals to ensure that no water passes into the ball bearings and in the bearing ring. An uninventive person familiar with the related art would not recognize the use of such a double row race ball bearing arrangement in a rotor fan application such as that of the present invention.

本发明惊奇地发现：通过用低摩擦、无/低接触密封件替换高摩擦密封件。使双列座圈轴承装置30适用在转子通风机中作为滚珠轴承装置，并与单列座圈滚珠轴承装置相比较具有几个优点。The present inventors have surprisingly discovered that by replacing high friction seals with low friction, no/low contact seals. Making the double row race bearing arrangement 30 suitable for use in a rotor fan as a ball bearing arrangement has several advantages over a single row race ball bearing arrangement.

在采用双列座圈滚珠轴承装置中，其优点的一个实例是：双列座圈滚珠轴承装置比单列座圈滚珠轴承装置有较好的横向稳定性和强度。所以，在如图3所列举的较小转子通风机实例情况下，一个双列座圈滚珠轴承装置需要保持转子足够的横向稳定度。采用一个单列座圈滚珠轴承装置是不能足以实现的。另一个实例在于：增强双列座圈滚珠轴承装置30的稳定性和强度，意味着能够将滚珠轴承装置30配置在平板18上方，并在某些条件下仍保持足够的横向稳定性是可能的。An example of the advantage of using a double row race ball bearing arrangement is that a double row race ball bearing arrangement has better lateral stability and strength than a single row race ball bearing arrangement. Therefore, in the case of the smaller rotor fan example shown in Figure 3, a double row race ball bearing arrangement is required to maintain sufficient lateral stability of the rotor. It is not sufficient to use a single row race ball bearing arrangement. Another example is that increasing the stability and strength of the double row race ball bearing unit 30 means that it is possible to deploy the ball bearing unit 30 above the plate 18 and still maintain sufficient lateral stability under certain conditions .

现在参照图4和图5，其中用相同的标号表示类似或相同的零件，示出的转子通风机的另一实施例比上面所述的转子通风机较大。附加的支承装置采用中间的轴承48，以提高该较大转子在使用中的横向稳定性。该中间支承48包括一个带端部50和52的结构件49。端部50安装到平板18上，而端部52安装到环形套筒21上。结构臂54从结构件49朝向轴13横向伸延。臂54的端部55与星形轮支承56相连接，该星形轮支承56可转动地安装到轴13上。Referring now to Figures 4 and 5, wherein like numerals are used to designate similar or identical parts, another embodiment of the rotor fan is shown which is larger than the rotor fan described above. Additional support means employs intermediate bearings 48 to increase the lateral stability of the larger rotor in use. The intermediate support 48 comprises a structural member 49 with ends 50 and 52 . End 50 is mounted to plate 18 and end 52 is mounted to annular sleeve 21 . A structural arm 54 extends transversely from the structural member 49 towards the shaft 13 . The end 55 of the arm 54 is connected to a spider bearing 56 which is rotatably mounted to the shaft 13 .

在使用时，例如在建筑物屋顶设置改进的通风机所需的孔。机座件10一般与屋顶呈固定连接，通过这种方法使轴13的位置基本上呈垂直位置，并能使转子17围绕轴13自由转动。因此，当空气通过转子通风机并使转子17如上述转动时，从转子通风机内部12排出的空气由来自屋顶下方的空气替换。然后排出废气，达到改善通风的效果。In use, for example, in building roofs to provide holes for improved ventilators. The base member 10 is generally fixedly connected to the roof, by which the shaft 13 is positioned substantially vertically and the rotor 17 can freely rotate around the shaft 13 . Thus, as air passes through the rotor ventilator and causes the rotor 17 to turn as described above, the air expelled from the rotor ventilator interior 12 is replaced by air from under the roof. Then the exhaust gas is discharged to achieve the effect of improving ventilation.

尽管本发明参照特定的实施例进行了说明，但对本领域普通技术人员会理解，本发明可以多种其它形式实现。Although the invention has been described with reference to specific embodiments, it will be appreciated by those skilled in the art that the invention may be embodied in various other forms.
