Abstract
The utility model discloses an automobile fan capable of automatically regulating dynamic balance. The automobile fan comprises a motor and a fan blade. A rotary shaft of the motor is fixedly provided with an embedment piece which comprises a hollow cylinder and a circular plane vertical to the hollow cylinder. The circular plane is provided with a plurality of protruding circular rings which are uniformly distributed. The center of the fan blade is provided with a clamping groove matched with the circular rings. The clamping groove comprises an outer blocking piece, an inner blocking piece, a tangential blocking piece and an inner circumference of the fan blade. A center through hole is formed in the hollow cylinder. The rotary shaft of the motor penetrates through the center through hole and is fixed to the center through hole in an interference fit mode. The number of the circular rings is three. The embedment piece is made of metal. The fan blade is made of plastic. The automobile fan has the advantages that the fan blade can automatically regulate dynamic balance, assembling is easy and quick, and materials are saved.
Description
Technical field
The utility model relates to the dynamically balanced automobile fan of a kind of automatic adjusting.
Background technique
Existing automobile fan is made up of motor and plastic blade usually, in order to improve the twisting strength of plastic blade, usually center and the motor rotation axis joining place at plastic blade is provided with metal insert, metal insert and plastic blade can be cast into one, the center that also metal insert can be embedded into plastic blade, and then be contained on the rotatingshaft of motor, fix with nut.Rigidity is connected between plastic blade and the inserts, and dynamic balancing cannot be regulated automatically during operation, and in addition, assembling and dismounting will be used instrument, and be not too convenient.
The model utility content
The utility model has proposed the dynamically balanced automobile fan of a kind of automatic adjusting in order to overcome above-mentioned deficiency, inserts is fixed on the rotatingshaft of motor, flexibly connects the adjusting dynamic balancing by inserts and plastic blade.
The technical solution of the utility model is:
The dynamically balanced automobile fan of a kind of automatic adjusting, comprise: motor, fan blade, inserts is fixedly arranged on the rotatingshaft of motor, inserts comprises that hollow cylinder reaches the disk perpendicular to hollow cylinder, this disk is provided with the annulus of several uniform protrusions, and the center of fan blade is provided with the draw-in groove that cooperates with this annulus.Described draw-in groove is made of the inner circumference of outer catch, interior catch, tangential catch and fan blade.
Need to prove that the space distance that outer catch, interior catch form is approximately greater than the thickness of annulus, so that inserts can be stuck in preferably
Need to prove that also tangential catch refers to, drives the catch that draw-in groove rotates when inserts rotates, when for example the motor counterclockwise rotated, during as object of reference, the catch in draw-in groove left side was tangential catch with the fan blade center.
As preferably, be provided with central through bore in the described hollow cylinder, the rotatingshaft of motor penetrates this central through bore and fixes with interference fit.
Consider the difficulty of intensity, the degree of balance, structure processing etc., as preferably, described annulus is provided with three.
As preferably, described inserts is made of metal.
Described fan blade is made of plastics.
The utlity model has the automatic adjustment of fan blade, assemble beneficial effect simple, quick, that save material.
Description of drawings
Fig. 1 is overall structure schematic representation of the present utility model.
Fig. 2 is blade structure schematic representation in the utility model.
Fig. 3 is insert structure schematic representation in the utility model.
Fig. 4 is that inserts cooperates the sectional view that amplifies in the utility model with fan blade.
Embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figures 1 to 4, the dynamically balanced automobile fan of a kind of automatic adjusting, comprise: motor 1, fan blade 2, inserts 3 is fixedly arranged on the rotatingshaft of motor 1, inserts 3 comprises hollow cylinder 32 and perpendicular to the disk 34 of hollow cylinder 32, is provided with central through bore 31 in the hollow cylinder 32, and the rotatingshaft of motor 1 penetrates this central through bore 31 and fixes with interference fit, this disk 34 is provided with the annulus 33 of several uniform protrusions, and the center of fan blade 2 is provided with the draw-in groove that cooperates with this annulus 33.
Draw-in groove is made of the inner circumference 22 of outer catch 23, interior catch 24, tangential catch 21 and fan blade 2.And constitute both ends of the surface sealing, both ends of the surface opening, and open end is used for inserts 3 and inserts, and Closed End is used for the spacing of inserts 3.For preventing axially rocking, the distance that outer catch 23, interior catch are 24 is slightly larger than the thickness of annulus 33, and the preferred 0.05-0.1mm of this difference is for preventing radially rocking, the external diameter of annulus 33 is slightly less than the internal diameter of the inner circumference 22 of fan blade 2, the preferred 0.05-0.1mm 0.05-0.2mm of this difference.
Can save the set screw of fan blade 2 with the utility model.
The quantity of annulus 33 can two, also can be more than three, and preferred three, if uniform, to reach balance.
During installation, the rotatingshaft interference fit of inserts 3 and motor 1, the opening end that annulus 33 is aimed at draw-in grooves press motor 1 sense of rotation and is rotated, and during dismounting, with vising rotatingshaft, with hand fan blade 2 opposite directions is withdrawed to get final product.
