Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
see also Fig. 1 to Fig. 4, the utility model provides a kind of impeller, comprise blade, wheel hub plate, described wheel hub plate comprises wheel hub shroud and wheel hub hub disk, be mould one-body molded, this wheel hub shroud and wheel hub hub disk are half slide structure, on wheel hub shroud 31 and wheel hub hub disk 32, equal correspondence is provided with mounting hole 2, fastening piece passes mounting hole 2 with wheel hub shroud 31 fixing form wheel hub plate 3 relative to wheel hub hub disk 32, lateral margin in wheel hub plate 3 is provided with some blade rotor mounting grooves 321, be provided with groove 322 on the inwall of blade rotor mounting groove 321, the rotating shaft 12 of root of blade is located in groove 322, fix by angle contract 4 screens between groove 322 and rotating shaft 12, angle contract 4 is a cylindrical body.
Described blade 1 is made of by mould is one-body molded blade body 11, rotating shaft 12 and rotating shaft angular positioning groove 13, wherein, rotating shaft 12 is located at the root of blade body 11, at rotating shaft 12 outer surface angulation locating slots 13, it is symmetrical that described angular positioning groove is two groups of circumference up and down, it is the locating slot of semicircle for a plurality of cross sections, be provided with the wheel hub angular positioning groove 323 consistent with rotating shaft angular positioning groove 13 in described groove 322, angle contract 4 is embedded in the cavity that forms between rotating shaft angular positioning groove 13 and wheel hub angular positioning groove 323, and shape is consistent with cavity shape.
Differential seat angle between described every group of angular positioning groove is 5 degree.
See also Fig. 5, be provided with some inner chambers in described blade body 11, its inner chamber cross section indention.
See also Fig. 6, the leading edge place of described blade body is provided with draw-in groove, and draw-in groove place's splicing has the external blade of the projection that is complementary with draw-in groove.
when assembling, first angle contract 1 is inserted in the angular positioning groove 323 of wheel hub shroud 31, then blade rotor 12 is placed in the interior groove 322 of half blade rotor mounting groove 321 of wheel hub shroud 31, and make it to be on the orientation angle of portraying by rotation blade 1, make blade rotor angular positioning groove 13 and angle contract 4 closely chimeric, realize accurately location, then wheel hub hub disk 32 is kept flat, insert angle contract 4, then blade 1 and 31 counter-rotatings of wheel hub shroud of having good positioning are inserted in wheel hub hub disk 32, utilize at last fastening piece that wheel hub shroud 31 and wheel hub hub disk 32 are fixed, realize fastening.
When blade 1 angle of impeller need to be regulated, take off from wheel hub shroud 31 first with disassembly of fastener, then with wheel hub hub disk 32, make it to be in by rotation blade 1 the accurate angle that needs adjusting, again wheel hub hub disk 32 is combined on wheel hub shroud 31 again, is fixed by fastening piece.
