Referring to Fig.1 shown in -2, preferred embodiment is provided for the utility model.
For the noise-reducing centrifugal spiral blade structure of running machine motor, including the turntable 1 for being fixedly connected with the rotor
And multiple air blades 2 being formed on turntable 1, center arranged for interval of multiple air blades 2 around turntable 1；Air blade 2 has
The fitting end face being bonded with turntable 1 is bonded the arc-shaped shape in end face.
The noise-reducing centrifugal spiral blade structure for running machine motor of above-mentioned offer, by setting for solid with rotor
Surely the turntable 1 and multiple air blades 2 being formed on turntable 1 connected, middle heart septum cloth of multiple air blades 2 around turntable 1
It sets；Air blade 2 has the fitting end face being bonded with turntable 1, is bonded the arc-shaped shape in end face；It is driven in this way, the rotor of motor rotates
Turntable 1 rotates, so that the air blade 2 on turntable 1 be driven to rotate, and then forms the air-flow in regular direction, that is, wind, generates
Wind will realize to the radiating and cooling of motor, extend the service life of motor, while the fitting end face of air blade 2 is arc-shaped
Shape, air blade 2 is streamlined, facilitates the circulation of air-flow, reduces the air drag between air-flow and air blade 2, reduces
The noise that air blade 2 generates when rotating, improves the using effect of user.
Specifically, turntable 1 is provided with multiple wind-guiding notch 3 passed through for air feed, and multiple wind-guiding notch 3 are around turntable 1
Center arranged for interval；In this way, air blade 2 constantly rotates, the air-flow in regular direction will necessarily be formed, wind-guiding notch 3 is set
It sets and circulates away convenient for air-flow from wind-guiding notch 3, enable the wind generated to there is a channel to be discharged, reduce the generation of noise.
Furthermore the side wall of wind-guiding notch 3 is streamlined；The side wall of wind-guiding notch 3 is streamlined, reduces air-flow and wind-guiding
Air drag between 3 side wall of notch thereby reduces the noise generated when air blade 2 works, provides greatly for user
It is convenient.
In the present embodiment, air blade 2, which has, deviates from end face 4 away from fitting end face, is in tilted layout away from end face 4.
