Determine portion it is close to each other so that connecting plate compress speed reducer rotation axis when, rotating wheel is smaller by being influenced, reduce turn
The case where driving wheel deforms, so that radiator fan is more steady in rotation.
Further, the junction of the connecting plate and the rotating wheel is also set up there are two through slot, and the through slot is arranged
In on rotating wheel and the lateral wall setting of two connecting plates of fitting, two through slots are centrosymmetric point along rotating wheel axis
Cloth, and the connection setting corresponding with two notches of two through slots.
Through the above technical solutions, setting two through slots so that rotating wheel be not susceptible to because connecting plate is close generate compared with
The case where big deformation, further reduces the connecting plate influence of crust deformation close to each other generated to rotating wheel, so that rotating wheel is whole
Structure is more stable.
Further, it is uniformly distributed circumferentially on the rotating wheel there are two gap group, the gap group is symmetrically distributed in
On the rotating wheel, and the plane of symmetry of two gap groups is overlapped with the plane of symmetry of two connecting plates.
Through the above technical solutions, two gap groups of setting, the deformation of rotating wheel is controlled by gap group, when two it is tight
Gu piece is by fastening bolt effect progress close to each other thus when being fixed in speed reducer rotation axis, the slight deformation of rotating wheel is basic
It concentrates at where two gap groups, so that the deformation position of rotating wheel is controllable, two gap groups are symmetrical arranged so that turning
The slight deformation of driving wheel is also at symmetrical position, generally make radiator fan generally in symmetry status, to make
The rotation for obtaining radiator fan is more stable, is conducive to the longtime running of radiator fan.
Further, heat shield is also provided on the opposite side wall in two abutting portions, the heat shield is in semicircle
Annular setting.
Through the above technical solutions, setting heat shield, connecting plate are contacted by heat shield with speed reducer rotation axis, it can oil
The case where heat transfer of the reduction speed reducer of case influences cooling fan structure intensity to radiator fan, so that radiator fan
Structure it is more stable.
Further, the heat shield is convexly equipped with fixed column close to the one end in the abutting portion, opens up in the abutting portion
There is the fixation hole for fixed column insertion.
Through the above technical solutions, setting fixed column and fixation hole, heat shield, which is inserted into fixation hole by fixed column, to be determined
Position is not easy to shift with connecting plate so that the position fixation of heat shield is more stable.
Compared with prior art, the utility model has the beneficial effects that
(1) by the way that radiator fan to be replaced with to the fan of plastic material, radiator fan is driven when speed reducer rotation axis rotates
When being radiated, whole energy consumption is relatively low, plays the effect of energy saving.In addition radiator fan is fixed on by connecting plate
In speed reducer rotation axis, so that radiator fan is more convenient along the adjusting of the axis direction position of speed reducer rotation axis, so that whole
Air flow adjustment it is more convenient；
(2) by two notches of setting, so that being not attached between fixed part and rotating wheel, so that fixed part is mutual
It is close so that connecting plate compress speed reducer rotation axis when, rotating wheel is smaller by being influenced, reduce rotating wheel deformation
Situation, so that radiator fan is more steady in rotation；
(3) by setting heat shield, connecting plate is contacted with speed reducer rotation axis by heat shield, can be subtracted with the reduction of fuel tank
The case where heat transfer of fast machine influences cooling fan structure intensity to radiator fan, so that the structure of radiator fan is more
Stablize.
