Description
Technical field
The present invention relates to a kind of motor radiating aerofoil fan, belong to field of motor manufacturing.
Background technology
Motor in addition to the output acting of most of energy, has portion of energy to be in meeting in alternating magnetic field due to iron core in operation
Magnetic hysteresis iron loss is produced, winding is because resistance can produce copper loss, also some other stray loss, and being produced with the situation of heat energy makes
The temperature rise of motor, and then the selection of the power density designs and the insulating materials trade mark of motor is had influence on, for rare earth permanent magnet
Motor then needs the magnet from the higher coercivity trade mark.For the radiating efficiency for reducing the temperature in use of motor, improving motor, lead to
Frequently with method be to increase radiating ribs or installation aerofoil fan, or increase water-cooling system, evaporative condenser system etc. in shell.
There is radiating efficiency deficiency in the above method, or need to increase a whole set of complication system and substantially increase what is used
Complexity and use cost.
The content of the invention
To solve the shortcomings that traditional heat-dissipating mode, the present invention proposes a kind of motor radiating aerofoil fan, concrete technical scheme
It is as follows：
The disk that a radius is more than rotating shaft is welded on machine shaft, internal gear is set on disk, forms " planetary gear
" gear ring " of system "；
Setting radius to be less than disk on machine shaft, simultaneously energy and rotating shaft can not be along electricity relative to the axle sleeve rotated with one heart, axle sleeve
Slide in machine shaft parallel direction；
Electric fan is welded in one end on axle sleeve, and the other end sets " central gear " of external gear formation " planetary gear train "；
One " planetary gear " is set between " gear ring " and " central gear ", " planetary gear " respectively and " gear ring ", " too
Positive gear " engages；
In electric machine casing inwall welding bracing frame, the axle of " planetary gear " is welded on support frame.
The wheel tine length of " gear ring " and " central gear " wheel tine length and axle sleeve radius and less than disc radius, " tooth
The number of gear teeth of circle " is more than the number of gear teeth of " central gear ".
Flabellum parameter is adjusted, air during motor operation is accelerated through flabellum, heat is taken away by fixed-rotor and air gap and plays
Accelerate the purpose of radiating and cooling.
When motor operation, rotated by machine shaft, drive disk and " gear ring " to rotate, " gear ring " is with machine shaft
Same angular velocity rotates, the linear velocity (number of teeth) 1 that " planetary gear " rotates " gear ring "：1 is transmitted to " central gear ", " sun
Gear " radius (number of teeth) is less than " gear ring " radius (number of teeth) and linear velocity identical with " gear ring " (number of teeth) rotates, therefore " the sun
The angular speed of gear " is more than " gear ring ", that is to say, that the rotating speed of flabellum is more than the rotating speed of machine shaft on axle sleeve.
In high speed operation of motor, to ensure the balance of machine shaft, it can be uniformly distributed in symmetric position and several are set
" planetary gear ".
The present invention has an advantageous effect in that compared with background technology：
New power resources need not be increased, system complexity increase is smaller, and simple in construction easily to realize, improvement cost is low,
Use cost is low, and radiating efficiency significantly improves.
