Description
Technical field
The utility model relates to a kind of parts of blower fan, the impeller of a kind of blower fan of more specifically saying so.
Background technique
The impeller of blower fan comprises wheel hub and blade, and wheel hub is provided with axle sleeve, can fix with the motor output shaft transmission, on the periphery of the wheel hub of vanes fixed.The blade pass of traditional draught fan impeller is crossed on the fixing wheel hub such as bolt or rivet, and there are deficiencies such as strength and stiffness are not high, running is unstable, energy consumption is big in this impeller.
State Intellectual Property Office on June 14th, 2006 disclosed " the double-deck wheel hub of large-scale air cooling blower fan " patent documentation (publication number: CN2787892), introduced the double-deck wheel hub of a kind of large-scale air cooling blower fan, comprise the upper and lower force-bearing steel plate that is loaded on the upper and lower both sides of large-scale air cooling fan blade root respectively, upper and lower force-bearing steel plate is fixedlyed connected with root of blade.This wheel hub can obviously improve the strength and stiffness of wheel hub, and is safe and reliable to operation.But its manufacturing, installation process complexity can not obviously improve fan operation efficient.
The model utility content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of impeller of blower fan, and it can make fan operation safe and reliable, and manufacturing, easy for installation, can also obviously improve fan operation efficient.
For addressing the above problem, the utility model has adopted following technological scheme: a kind of impeller of blower fan, it comprises circular wheel hub and blade, described wheel hub is provided with axle sleeve, described vanes fixed is at the periphery of wheel hub, described wheel hub comprises last wheel hub plate and the lower whorl hub that is connected mutually, described blade comprises petiole and fan blade, on the side face of described wheel hub, has fan blade fixed hole more than two along normal direction, the degree of depth of described fan blade fixed hole is less than the radius of wheel hub, and the petiole of described blade comprises stationary axle and end, and the diameter of described end is greater than the diameter of stationary axle; Institute's stationary axle that is set forth in and fan blade fixed hole drive fit.
The impeller of above-mentioned blower fan, described fan blade is being a circular arc near a side of petiole, and described fan blade matches with the circle of wheel hub in the circular arc near a side of petiole, promptly fan blade nestles up the side face of wheel hub in a side of close petiole.
As improvement, on the side face of described wheel hub, be provided with mark near the fan blade fixed hole, described fan blade also is provided with mark near the petiole position.
Adopt such scheme, on the side face of described wheel hub, has fan blade fixed hole more than two along normal direction, the petiole of described blade comprises stationary axle and end, the diameter of described end is greater than the diameter of stationary axle, and dead axle and fan blade fixed hole drive fit, this structure makes the installation of blade and wheel hub very convenient, and the angle of its blade can be regulated according to usage requirement.Described fan blade is a circular arc in the side near petiole, make fan blade nestle up the side face of wheel hub in a side near petiole, near when having eliminated conventional impellers work like this blade petiole turbulent flow, can increase substantially the working efficiency of blower fan, reduce energy consumption, warp adopts impeller of the present utility model can economize on electricity about 10% to the repeatedly experiment of the draught fan impeller of different size.Near the fan blade fixed hole, be provided with mark, the angle of conveniently adjusted blade near the petiole position with fan blade.Therefore impeller of the present utility model has safe and reliable to operationly, makes, installation process is simple, can also obviously improve fan operation efficient.
