In the assembly structure of the motor designed by the present invention, the coupling member 4 between the two transmission members is matched by the structure of the first transmission member 4 1 on the drive shaft 20 and the second transmission member 4 2 on the spindle 20 1 . So that the motor 100 can directly achieve the radial coaxial drive with the mandrel 2 〇1 of the base 2 ,1, as shown in Figures 5 and 6, without the need for additional concentric correction before assembly. Homework. Furthermore, since the motor 100 in the assembled structure, the mandrel 2 〇1 of the base 2, the first transmission member 4 1 , the second transmission member 4 2 and the coupling ridge 4 3 together achieve radial coaxial drive When the power transmission is performed by the assembly structure of the horse that is designed by the present invention, the coupling member 43 interposed between the first transmission member 4 i and the second transmission member 42 is at the large diameter portion of the drive shaft 2 2 2 is subjected to the mechanical torsion of the transmission member, and the coupling member 43 can automatically eliminate the tolerance of the mandrel between the two shafts while being pressed, thereby greatly reducing the vibration phenomenon when transmitting power, especially avoiding starting. The moments generated by the moment are frustrated, so as to ensure the smoothness and accuracy of the transmission of the overall movement. In addition, only the coupling member 43 which directly bears the transmission and is naturally worn during the subsequent maintenance and repair can save the maintenance cost of the maintenance, and the first transmission member 4 and the second transmission can be extended by the arrangement of the coupling member 43. The effective operation of the piece 4 2 is to improve the motor i Q (4) The durability period is 100102569.
