Combination of motor and wind wheel

Abstract

A combination of a motor and a wind wheel. The motor includes a shaft ( 11 ) including a plurality of mounting holes ( 21 ). The wind wheel ( 2 ) is arranged on the motor ( 1 ). A plurality of wind blades ( 22 ) is arranged on the mounting plate ( 21 ). A first through hole ( 210 ) is disposed on a middle part of the mounting plate ( 21 ). A boss ( 23 ) is disposed on the mounting plate ( 21 ) outside the first through hole ( 210 ). A second through hole ( 230 ) is arranged on the boss ( 23 ). A plurality of mounting holes ( 110 ) is arranged on the shaft ( 11 ). The shaft ( 11 ) passes through the first through hole ( 210 ). A screw ( 3 ) passes through the second through hole ( 230 ) and is inserted into the mounting hole ( 110 ) for fastening the wind wheel ( 2 ) on the shaft ( 11 ).

The invention claimed is: 
     
         1 . A combination of a motor and a wind wheel, the motor comprising a shaft ( 11 ), the shaft ( 11 ) comprising a plurality of mounting holes ( 110 ), and the wind wheel ( 2 ) comprising a mounting plate ( 21 ), a plurality of wind blades ( 22 ), a first through hole ( 210 ), and a boss ( 23 );
 wherein:
 the wind wheel ( 2 ) is arranged on the motor ( 1 ); 
 the wind blades ( 22 ) are arranged on the mounting plate ( 21 ); 
 the first through hole ( 210 ) is disposed on a middle part of the mounting plate ( 21 ); 
 the boss ( 23 ) is disposed on the mounting plate ( 21 ) outside the first through hole ( 210 ); 
 a second through hole ( 230 ) is arranged on the boss ( 23 ); 
 the shaft ( 11 ) passes through the first through hole ( 210 ); and 
 a screw ( 3 ) passes through the second through hole ( 230 ) and is inserted into the mounting hole ( 110 ) for fastening the wind wheel ( 2 ) on the shaft ( 11 ). 
   
     
     
         2 . The combination of  claim 1 , wherein the mounting hole ( 110 ) is a circular recess or a square notch. 
     
     
         3 . The combination of  claim 1 , wherein
 a neck ( 111 ) is arranged on the shaft ( 11 ); and   a clamp spring ( 4 ) is inserted into the neck ( 111 ) for fastening the mounting plate ( 21 ) of the wind wheel ( 2 ).   
     
     
         4 . The combination of  claim 2 , wherein
 a neck ( 111 ) is arranged on the shaft ( 11 ); and   a clamp spring ( 4 ) is inserted into the neck ( 111 ) for fastening on the mounting plate ( 21 ) of the wind wheel ( 2 ).   
     
     
         5 . The combination of  claim 1 , wherein
 four mounting holes ( 110 ) are provided;   every two mounting holes ( 110 ) are arranged in a group; and   two groups of the mounting holes ( 110 ) are distributed on two ends of the shaft ( 11 ), respectively.
