the motor front cover designed according to the purpose comprises a front cover body, wherein a rotating shaft mounting part which extends towards the upper side and the lower side is arranged at the axis of the front cover body, and a shaft hole for penetrating a rotating shaft is formed in the rotating shaft mounting part;
preferably, the inner walls of the upper end and the lower end of the shaft hole are provided with bearing mounting grooves for mounting a bearing;
preferably, the upper outer wall surface of the rotating shaft mounting part is an inclined surface which is gradually inclined outwards from top to bottom;
a motor structure with good stability comprises a motor front cover and a motor rear cover, wherein a rotating shaft is formed on the motor rear cover through one-step injection molding, a rotor is fixed on the inner wall of the motor rear cover, a stator assembly is fixedly installed at the lower part of a rotating shaft installation part, a bearing is installed in a bearing installation groove, and the rotating shaft penetrates through the bearing and extends upwards;
the utility model has the advantages of simple and reasonable structure and good stability, and compared with the prior art, the utility model comprises a front cover body, wherein the axle center of the front cover body is provided with a rotating shaft mounting part which extends towards the upper side and the lower side respectively, and the rotating shaft mounting part is internally provided with an axle hole for penetrating a rotating shaft, namely, the rotating shaft mounting part extends towards the upper side and the lower side respectively, so that the mounting distance of the rotating shaft is lengthened, the integral stability is ensured, and the use requirement is met.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention;
fig. 2 is an exploded view of the present invention.
Detailed Description
