Abstract
The invention relates to an intermediate-frequency power generator fan and a production process thereof. The intermediate-frequency power generator fan is characterized by comprising a fan hub and a plurality of plane-shaped fan blades fixedly arranged on the fan hub; each plane-shaped fan blade is parallel to a fan rotating axis; and on a projecting plane vertical to the fan rotating axis, an angle theta between a connecting line of an end point of a fan blade projecting line adjacent to the fan axis and a fan axis point and the fan blade projecting line is more than or equal to 52 degrees and is less than or equal to 55 degrees. The intermediate-frequency power generator fan has the advantages of simple structure, reasonable design and wide market prospect, and has not only considerable economic benefit, but also remarkable social benefit.
Description
technical field:
Patent of the present invention relates to technical field of generators, especially a kind of intermediate-frequenpower power generator fan and production technology thereof.
background technique:
Intermediate frequency generator can send midfrequent AC power supply and be applied by aircraft, professional electric heating equipment.Due to the weakness that the progression of this kind of generator is many, electromagnetism density is high, heat radiation becomes it, wherein major reason is the unreasonable of its fan design, causes fan easily to damage.
summary of the invention:
The object of the present invention is to provide a kind of intermediate-frequenpower power generator fan and production technology thereof, this intermediate-frequenpower power generator fan structure is simple, reasonable in design, long service life, is conducive to for intermediate frequency generator provides enough wind-force, and can reduces the damage of fan.
Intermediate-frequenpower power generator fan of the present invention, it is characterized in that: the some plate plane shape fan blades comprising fan hub and be fixedly located in fan hub, described each plane fan blade parallels with fan rotation axis heart line, and on the projection plane perpendicular to fan rotation axis heart line, fan blade projection line to follow the wind the angle θ that the line of fan AnchorPoint and fan blade projection line formed near the end points of Fan axial center, 52 degree≤θ≤56 degree.
Above-mentioned θ is 55 degree.
Said fans wheel hub is circumferentially fixedly welded with 10 plate plane shape fan blades.
Said fans wheel hub and plane fan blade are all stamped to form by metal material.
Said fans wheel hub is formed by fixing former, frustum and bilge ways, and plane fan blade is welded on frustum and bilge ways outer surface.
Above-mentioned plane fan blade upper weld has retainer ring.
The production technology of intermediate-frequenpower power generator fan of the present invention, it is characterized in that: punching press fan hub, plane fan blade and retainer ring are for subsequent use first respectively, then rule on the surface in fan hub, to determine the fixed position of plane fan blade, then position welds plane fan blade one by one to the layout line, is finally welded and fixed circle.
Intermediate-frequenpower power generator fan of the present invention is paralleled with fan rotation axis heart line by each plane fan blade, and on the projection plane perpendicular to fan rotation axis heart line, fan blade projection line to follow the wind the angle θ that the line of fan AnchorPoint and fan blade projection line formed near the end points of Fan axial center, 52 degree≤θ≤56 degree, thus the air quantity that this fan is produced foot, solve the ventilation and heat of generator, again reducing noise effectively, and the damage of fan can be reduced.
accompanying drawing illustrates:
Fig. 1 is the structural representation of intermediate-frequenpower power generator fan of the present invention;
Fig. 2 is the plan view of intermediate-frequenpower power generator fan of the present invention;
Fig. 3 is the A-A sectional drawing of Fig. 2.
embodiment:
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Intermediate-frequenpower power generator fan of the present invention, the some plate plane shape fan blades 2 comprising fan hub 1 and be fixedly located in fan hub 1, described each plane fan blade 2 parallels with fan rotation axis heart line 3, and on the projection plane 4 perpendicular to fan rotation axis heart line, fan blade projection line to follow the wind the angle θ that the line of fan AnchorPoint and fan blade projection line formed near the end points 5 of Fan axial center, 52 degree≤θ≤56 degree.
Reasonable in order to what design, above-mentioned θ is 55 degree.Said fans wheel hub is circumferentially fixedly welded with 10 plate plane shape fan blades.
Said fans wheel hub and plane fan blade are all stamped to form by metal material.
In order to install fixing needs, said fans wheel hub 1 is made up of fixing former 101, frustum 102 and base 103 plate, and plane fan blade is welded on frustum and bilge ways outer surface.
In order to improve the soundness of connection, above-mentioned plane fan blade upper weld has retainer ring 6.
The production technology of intermediate-frequenpower power generator fan of the present invention,, punching press fan hub, plane fan blade and retainer ring are for subsequent use first respectively, then rule on the surface in fan hub, to determine the fixed position of plane fan blade, then position welds plane fan blade one by one to the layout line, is finally welded and fixed circle.
Intermediate-frequenpower power generator fan of the present invention is paralleled with fan rotation axis heart line by each plane fan blade, and on the projection plane perpendicular to fan rotation axis heart line, fan blade projection line to follow the wind the angle θ that the line of fan AnchorPoint and fan blade projection line formed near the end points of Fan axial center, 52 degree≤θ≤56 degree, thus the air quantity that this fan is produced foot, solve the ventilation and heat of generator, again reducing noise effectively, and the damage of fan can be reduced.
