Description

A kind of blender series excited machine blade structure

Technical field

This utility model is related to design of electrical motor manufacture field, more particularly to a kind of blender series excited machine blade structure.

Background technology

Motor is used as power output in every field, and the fan blade on motor is non-as the cooling element of motor Chang Guanjian, have impact on performance and the life-span of motor.The fan blade for using at present is mostly working of plastics, has part to be metalwork.And fan blade Structure it is many based on axial-flow leaf, while there is part centrifugal fan blade, so require that the wind path of overall design is very reasonable.When During the limited configurations of whole machine, such as when for blender, it is desirable to which outside can not have the passage that can enter water, while blender Upward, fan blade is necessarily mounted at following spindle nose, cannot thus use axial-flow leaf, while the rotating speed of blender is very high, work( In the case that rate is all very big, general fan blade is not adapted to, so just having to redesign whole machine blade structure.

Utility model content

In order to solve above-mentioned technical problem, there is provided a kind of centrifugal fan structure that can be applied to high rotating speed blender, This utility model provides technical scheme below：

A kind of blender series excited machine blade structure, including bearing block, substrate, cover plate, internal layer blade and outer layer leaf Piece；The substrate is annular disc；The bearing block is fixedly connected with substrate inner ring, and axially vertical with base plan；It is described Cover plate includes planar section and parabolic sections, and the planar section is also annular disc, and its internal diameter is less than base more than substrate internal diameter, external diameter Plate external diameter；Described parabolic sections one end is connected with planar section, and the other end to the direction away from substrate extends；The planar section and base Plate is parallel；The internal layer blade is arranged between planar section and substrate, and vertical with substrate；The outer blade is arranged at parabolic It is between face section and substrate and vertical with substrate.Double-deck blade structure compares that single layer blade air-out is in hgher efficiency, and parabolic sections set Put so that air-out open area increase during secondary air-out, and cause more smooth to the air inducing of outer layer fan blade from internal layer fan blade.

Further, the internal layer blade is arc tabular, the internal layer blade and outer blade with outer blade Inlet air leaf margin is disposed as fillet, is conducive to reducing the windage at inlet air leaf margin.

Further, the internal layer blade is gradually reduced from inlet air leaf margin to air-out leaf margin thickness, and the outer blade is thick Degree is equal everywhere；Internal layer blade primarily serves the effect of centrifugation, and for changing wind direction, the active force received at inlet air leaf margin is most Greatly, thus arranged it is thicker.

Further, the internal layer number of blade is the 1/2 of outer blade number, and the air-out efficiency under the ratio is optimal.

The beneficial effects of the utility model are：Suitable for the radiating of high-power and high-speed blender, with Stability Analysis of Structures, The little advantage of air-out efficiency high, noise.

Specific embodiment

A kind of blender series excited machine blade structure as shown in Figure 1, including bearing block 1, substrate 2, cover plate 3, internal layer Blade 4 and outer blade 5；The substrate 2 is annular disc；The bearing block 1 is fixedly connected with the inner ring of substrate 2, and axially It is vertical with the plane of substrate 2；The cover plate 3 includes planar section 31 and parabolic sections 32, and the planar section 31 is also annular disc, its Internal diameter is less than the external diameter of substrate 2 more than the internal diameter of substrate 2, external diameter；The one end of the parabolic sections 32 is connected with planar section 31, the other end to Extend away from the direction of substrate 2；The planar section 31 is parallel with substrate 2；The internal layer blade 4 is arranged at planar section 31 and substrate It is between 2 and vertical with substrate 2；The outer blade 5 is arranged between parabolic sections 32 and substrate 2, and vertical with substrate 2.It is double Layer blade structure compares that single layer blade air-out is in hgher efficiency, and air-out open area increases when the setting of parabolic sections 32 causes secondary air-out Greatly, it is and so that more smooth to the air inducing of outer layer fan blade from internal layer fan blade.Whole blade structure adopts metallic aluminium in the present embodiment Make.

The internal layer blade 4 is arc tabular with outer blade 5, and the internal layer blade 4 enters fan blade with outer blade 5 Edge is disposed as fillet, is conducive to reducing the windage at inlet air leaf margin.

The internal layer blade 4 is gradually reduced from inlet air leaf margin to air-out leaf margin thickness, the thickness of the outer blade 5 phase everywhere Deng；Internal layer blade 4 primarily serves the effect of centrifugation, and for changing wind direction, the active force received at inlet air leaf margin is maximum, therefore will It is thicker that it is arranged.

The number of internal layer blade 4 is the 1/2 of the number of outer blade 5, and the air-out efficiency under the ratio is optimal.

The blade structure of the present embodiment is as shown in Figure 2 with the attachment structure of series excited machine 100.

With above-mentioned foundation this utility model desirable embodiment as enlightenment, by above-mentioned description, relevant staff Completely various change and modification can be carried out in the range of without departing from this utility model technological thought.This practicality New technical scope is not limited to the content in description, it is necessary to determine its according to right technical Scope.
