Abstract
The utility model discloses a blade angle positioning structure of an impeller. The blade angle positioning structure comprises blades and a hub disc, a plurality of blade rotary shaft mounting grooves are arranged at side edges of the hub disc, and grooves are mounted on inner walls of the blade rotary shaft mounting grooves. The blade angle positioning structure is characterized in that the blades comprise blade bodies, rotary shafts are mounted at roots of the blade bodies, angle positioning grooves are formed on outer surfaces of the rotary shafts, hub angle positioning grooves which are correspondingly matched with the rotary shaft angle positioning grooves are mounted in the grooves, angle wedges are embedded into cavities formed between the rotary shaft angle positioning grooves and the hub angle positioning grooves, and shapes of the angle wedges are consistent with those of the cavities. According to the blade angle positioning structure of the impeller, the angle positioning grooves are arranged on the blade rotary shafts, so that the blades can be rapidly positioned at optimum angles during mounting.
Description
Technical field
The utility model is a kind of impeller blade angle locator.
Background technique
At present, existing blade wheel structure is in whole installation process, the installation of its Leaf bothers most, because the angle of each blade will need to be adjusted to equally, and angle is also wanted accurately, so in debug process, need blade angle to be adjusted to the right place by repeatedly adjusting, such problem that produces is exactly the blade angle location difficulty, deviation easily occurs, and skew easily occurs and impeller performance is exerted an influence in running Leaf angle.
Summary of the invention
Angle location difficulty when the utility model will solve existing blade wheel structure Leaf installation, running Leaf angle is the technical problem of skew easily.
The technical scheme in the invention for solving the above technical problem is:
the utility model discloses a kind of impeller blade angle locator, comprise blade and wheel hub plate, lateral margin in wheel hub plate is provided with some blade rotor mounting grooves, be provided with groove on the inwall of blade rotor mounting groove, it is characterized in that: described blade comprises blade body, rotating shaft is located at the root of blade body, at rotating shaft outer surface angulation locating slot, be provided with the wheel hub angular positioning groove with the corresponding coupling of rotating shaft angular positioning groove in described groove, the angle contract is embedded in the cavity that forms between rotating shaft angular positioning groove and wheel hub angular positioning groove, shape is consistent with cavity shape.
It is symmetrical that described blade rotor angular positioning groove is two groups of circumference up and down, is the locating slot of semicircle for a plurality of cross sections; The distributed architecture of described wheel hub angular positioning groove is consistent with the rotating shaft angular positioning groove distributed architecture of every group.
Differential seat angle between described every group of angular positioning groove is 5 degree.
Described wheel hub plate comprises wheel hub shroud and wheel hub hub disk, and this wheel hub shroud and wheel hub hub disk are half slide structure.
The beneficial effects of the utility model are: compare with existing impeller blade package assembly, the rotating shaft of blade described in the utility model is provided with the angular positioning groove, by the angular positioning groove, in assembly process, can rapidly blade be adjusted to the right place, design factors contract in locating slot very reaches the fixing effect that is not offset of blade.

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 blade angle locator, comprise blade 1 and wheel hub plate 3, 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, described blade 1 comprises blade body 11, rotating shaft 12 is located at the root of blade body 11, at rotating shaft 12 outer surface angulation locating slots 13, be provided with the wheel hub angular positioning groove 323 with rotating shaft angular positioning groove 13 corresponding couplings 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, shape is consistent with cavity shape.
It is symmetrical that described blade rotor angular positioning groove 13 is two groups of circumference up and down, is the locating slot of semicircle for a plurality of cross sections; The distributed architecture of described wheel hub angular positioning groove 323 is consistent with rotating shaft angular positioning groove 13 distributed architectures of every group.
Differential seat angle between described every group of angular positioning groove is 5 degree.
Described wheel hub plate 3 comprises wheel hub shroud 31 and wheel hub hub disk 32, and this wheel hub shroud 31 is half slide structure with wheel hub hub disk 32.
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.
