Abstract
The invention discloses a fan blade of a generator rotor, and belongs to the field of automobile fittings. The fan blade of the generator rotor overcomes the shortcomings of low machining efficiency and disassembly and mounting difficulties of the fan blade of an automobile generator rotor in the prior art. The fan blade of the generator rotor mainly comprises a fan blade plate. Vanes are arranged on the fan blade plate, and are uniformly and helically distributed on the fan blade plate at equal intervals. Two reinforcement ribs are arranged at a joint between the fan blade plate and each vane. The center of the fan blade plate is provided with a positioning ring. The periphery of the positioning ring is uniformly provided with six solder joints capable of spot-welding the fan blade plate on the rotor. The fan blade of the generator rotor is mainly used for the automobile generator.
Description
Technical field
The invention belongs to the auto parts machinery field, specifically, relate in particular to the generator amature fan blade that uses on a kind of automobile.
Background technology
The generator amature fan blade is stamped to form by the 08F material, and it is welded on the extreme face of pawl of two ends of rotor by point, plays thermolysis in generator.Traditional fan blade leans on tool locating when spot welding, and the spacing collar of fan blade is too high, influences dismounting of rotor rear bearing and whole machine installation.Simultaneously, the number of welds of traditional fan blade is too much, and the spot welding frock is unfavorable for processing, and operating efficiency reduces.
Summary of the invention
In order to overcome the defective that the working (machining) efficiency that the generator amature fan blade exists in the prior art is low, remove and install difficulty, the invention provides a kind of new type electric generator rotor fan blade.
The object of the present invention is achieved like this:
A kind of generator amature fan blade, comprise wind acanthus leaf, wind acanthus leaf is provided with blade, described blade is spirally distributed on the wind acanthus leaf uniformly and equidistantly, the junction of wind acanthus leaf and each blade is provided with 2 reinforcements, and wind acanthus leaf central authorities are provided with centring ring, and the centring ring periphery evenly is provided with 6 energy wind acanthus leaf is welded to epitrochanterian solder joint.
Preferably, described wind acanthus leaf is provided with stopper slot.
Preferably, described wind acanthus leaf is provided with holddown groove.
Compared with prior art, the present invention has following advantage and progress:
(1) be beneficial to the dismounting and the whole machine installation of bearing, the reduction of number of welds improves spot welding efficient, and performance is more stable, the friction risk of fan blade and bonnet tolerance ring when also reducing assembling.
(2) the spacing collar of traditional fan blade cancellation, need not lean on tool locating during fan blade spot welding, by in the rotating shaft with the back-up ring positioning instant can.
(3) quantity of fan blade solder joint also drops to present 6 from original 12, is beneficial to the processing of spot welding frock, and the fan blade location after the change is convenient, and spot welding efficient improves.
(4) number of blades also makes 6 into from original 7, and increases by two reinforcements at each blade and wind acanthus leaf junction, makes overall structure more reasonable, and blade also is not easy distortion, and fan blade is just longer useful life.
(5) increase stopper slot and holddown groove on fan blade, stopper slot is in order to make to need only with the cement gel anchor leg time stopper slot to be coated with completely with cement gel, just can play the purpose of anchor leg, and is simple, convenient.Holddown groove is can the setting-up piece spacer when adding a pad if desired below fan blade, and when making the fan blade welding, pad is not easy play, influences fan blade spot welding.

Accompanying drawing is a structural representation of the present invention
The 1-wind acanthus leaf; The 2-stopper slot; The 3-solder joint; The 4-centring ring; The 5-blade; The 6-reinforcement; The 7-holddown groove.
Embodiment
The present invention is described further below in conjunction with drawings and Examples, but protection scope of the present invention is not limited to these embodiment.Every do not deviate from the change of the present invention design or be equal to substitute include within protection scope of the present invention.
As shown in the figure:
A kind of generator amature fan blade, comprise wind acanthus leaf 1 and blade 5, described blade 5 is spirally distributed on the wind acanthus leaf 1 uniformly and equidistantly, wind acanthus leaf 1 is provided with 2 reinforcements 6 with the junction of each blade 5, and wind acanthus leaf 1 central authorities are provided with centring ring 4, and centring ring 4 peripheries evenly are provided with 6 energy wind acanthus leaf 1 is welded to epitrochanterian solder joint 3; Wind acanthus leaf 1 is provided with stopper slot 2 and holddown groove 7.Stopper slot 2 is in order to make to need only with the cement gel anchor leg time stopper slot 2 usefulness cement gels to be coated with completely, just can play the purpose of anchor leg, and is simple, convenient.Holddown groove 7 is can the setting-up piece spacer when adding a pad if desired below fan blade, and when making the fan blade welding, pad is not easy play, does not influence fan blade spot welding.
The present invention is set on the rotor in use.
