Embodiment
As described in Figure 1, the utility model mainly comprises slip ring 1, motor 2, one-level impeller 3, transmission device 4, sencond stage impeller 5 and casing 6.
As Fig. 2, transmission device comprises live axle 41, actuation gear 42 (1), driving gear 43 (2 or 4), working gear 44 (1), working shaft 45, stationary axle 46, cross axle 47 and transmission shell 48.Live axle 41 two ends are connected with one-level impeller 3, actuation gear 42 respectively.Working shaft 45 two ends are connected with working gear 44, sencond stage impeller 5 respectively.Driving gear 43 is by the intermeshing connection of cross axle 47.Stationary axle 46 1 end connection for transmission gears 43, the other end is fixed on casing 6.Actuation gear 42, driving gear 43, working gear 44, cross axle 47 all are placed in the inside of transmission shell 48, and transmission shell 48 not only can play a protective role to internal gear, and contribute to the engagement of actuation gear 42, working gear 44 and driving gear 43.
During work, motor 2 drives one-level impeller 3 to rotate, and one-level impeller 3 drives actuation gear 42 by transmission shaft 41 and rotates, actuation gear 42 band nutating gears 43, and stationary axle 46 can prevent that driving gear 43 integral body are with the 3 circumferencial direction revolution of one-level impeller.Through driving gear 43, working gear 44 is rotated, working gear 44 rotates by working shaft 45 and drives sencond stage impeller 5.Two groups of vane group are revolved structure in pairs, realize one-level impeller 3, sencond stage impeller 5 counterrotatings.Both stage impellers is active wheel stator each other again, the eddy current produced during rotation and moment of torsion can be cancelled each other or most of the counteracting, thereby the energy loss that eddy current can be caused reduces as far as possible, thereby the drafting efficiency improved, in the situation that identical output power, blast increases by 8%～15%, has also improved the stability of ventilator simultaneously
The blades installation opposite direction of the blade of one-level impeller 3 and sencond stage impeller 5, realize that two groups of blade counterrotatings are that wind direction is consistent.
As Fig. 3, Fig. 4, one-level impeller 3 is different from the blade shape of sencond stage impeller 5, the number difference, and the number of blade of one-level impeller 3 is 8, the number of blade of sencond stage impeller 5 is 7, has reduced the noise that blade resonance produces.
One-level impeller 3 is that the hard amount of aluminum-magnesium alloy matter is light, corrosion stability is stronger with the blade material of sencond stage impeller 5, and intensity and good heat conductivity, be difficult for getting rusty, and has extended blade working life.
In sum, with propeller fan in the past, compare, this use is novel to have the following advantages:
Two groups of vane group are revolved structure in pairs, both stage impellers is active wheel stator each other again, the eddy current produced during rotation and moment of torsion can be cancelled each other or most of the counteracting, thereby the energy loss that eddy current can be caused reduces as far as possible, thereby the drafting efficiency improved, in the situation that identical output power, blast increases by 8%～15%, has also improved the stability of ventilator simultaneously.
The hard amount of aluminum-magnesium alloy blade matter is light, density is low, corrosion stability is stronger, and intensity and good heat conductivity, be difficult for getting rusty, long service life.
Motor and impeller directly connect, and have avoided the energy loss of transmission between motor and impeller, have eliminated the phenomenon of the easily deformable damage of transmission part.
Two interlobate transmission devices adopt the planetary pinion of pure torsion transmission, and loss in efficiency is little, and transmission ratio is high, and the power that in planetary pinion, each outer gear is assigned to is equal, and power output is very steady.
Inverted ventilation is good, and general blower fan Reverse is about 40～50%, and the blower fan reversed for double-leaf, its Reverse can reach 60～70%.
Above-mentioned mode of execution is not to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in the technical solution of the utility model scope, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
