Abstract
The utility model relates to axial flow fan fittings, in particular to an axial flow fan hub which comprises a rim. An axial hole is formed in the center of the rim. The rim is connected with the axial hole through spokes. One end of each spoke is fixedly connected with the axial hole, and the other end of each spoke is inserted into an O-shaped gasket. The O-shaped gaskets are fixedly stuck to the inner wall of the rim. According to the axial flow fan hub, due to the fact that the O-shaped gaskets are fixedly stuck to the inner wall of the rim, installation holes do not need to be formed in the rim in advance, part processing steps are simplified, the cost of the O-shaped gaskets is smaller than that of original T-shaped gaskets, processing is easier, and the efficiency of the whole processing and assembling is improved.
Description
Technical field
The utility model relates to a kind of propeller fan accessory, especially a kind of propeller fan wheel hub.
Background technique
Axial fan is again booster, the conventional a kind of blower fans of industrial and mining enterprise, it is different from general blower fan, its motor and fan blade are all in a cylinder, and profile is exactly a tubular, for local ventilation, easy for installation, ventilation successful, safety, the cylinder of can giving a dinner for a visitor from afar is kept watch and is delivered to the region of appointment.To axial flow rotary blower fan, be to adopt hollow shaft and solid shaft to be nested together, the principle that shaft centre line is overlapping, makes two impellers of blower fan can install very closely.
As depicted in figs. 1 and 2, in existing blower fan, impeller is installed in wheel rim 1, and wheel rim 1 center is provided with axis hole 2, between wheel rim 1 and axis hole 2, by spoke 3, is connected, existing spoke 3 mounting structures are, on wheel rim 1, bore spoke mounting hole 11, inverted T-shaped packing ring 4 is installed in spoke mounting hole 11, by the mounting hole 11 on partial insertion wheel rim thinner on inverted T-shaped packing ring 4, thicker part is used for fixing to spoke 3, and whole installation processing and installation process are complicated.
Model utility content
The utility model provides a kind of simplification component processing and installation step, improves the propeller fan wheel hub of work efficiency.
To achieve these goals, the utility model adopts following technological scheme:
Comprise a wheel rim, wheel rim center is provided with axis hole, between wheel rim and axis hole, by spoke, is connected, and one end and the axis hole of described spoke are fixed, and its improvement is: the other end inserts in an O-ring gasket, and O-ring gasket is pasted the inwall that is fixed on wheel rim.
Preferably, centered by described spoke one axis hole, equal angles distributes.
Preferably, on described spoke, be also provided with stiffening rib.
Owing to having adopted said structure, propeller fan wheel hub of the present utility model is pasted fixing and wheel rim inwall by O-ring gasket, without set in advance mounting hole on wheel rim, has simplified the process step of parts again, and select O-ring gasket lower than original T shape packing ring cost, process also simpler.Therefore improved the efficiency of whole processing and assembling.
Accompanying drawing explanation
Fig. 1 is existing wheel hub cross section structure schematic diagram;
Fig. 2 is existing wheel hub side external structure schematic diagram;
Fig. 3 is the utility model embodiment cross section structure schematic diagram
Fig. 4 is the utility model embodiment's external structure schematic diagram.
In figure:
T shape packing ring 4;
O-ring gasket 5;
Embodiment
As shown in Figure 3, the utility model embodiment's propeller fan wheel hub comprises a wheel rim 1, wheel rim 1 center is provided with axis hole 2, between wheel rim 1 and axis hole 2, by spoke 3, be connected, one end of described spoke 3 and axis hole 2 are fixing, the other end inserts in an O-ring gasket 5, and O-ring gasket 5 is pasted the inwall that is fixed on wheel rim 1.
In order to keep stability attractive in appearance and operation, in the present embodiment, described spoke 3 equal angles centered by axis hole 2 distributes.
In order to increase the intensity of spoke 3, in the present embodiment, on described spoke 3, be also provided with stiffening rib 6.
Add man-hour, by O-ring gasket, paste fixing and wheel rim inwall, as shown in Figure 4, without set in advance again mounting hole on wheel rim, simplified the process step of parts, and selected O-ring gasket lower than original T shape packing ring cost, process also simpler.Therefore improved the efficiency of whole processing and assembling.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
