Embodiment 1

[0021] Example 1: as figure 1 In the embodiment shown, a quick-installed motor includes a wind guide wheel 1, a moving impeller 2, a wind cover 3, and a casing 4. The wind guide wheel and the moving impeller are located in the wind cover, and also includes carbon. Brushes, rotors 5, stators 6, and shafts 7 coaxially connected to the rotors. The shafts are provided with inner bearings 8 and outer bearings 9. The middle of the wind guide wheel is provided with a bearing matching groove. The groove is coaxial with the wind guide wheel, the inner bearing is located in the bearing matching groove, the rotating shaft is connected with the inner ring of the inner bearing, the rotating shaft is connected with the inner ring of the outer bearing, and the outer ring of the inner bearing is connected with the bearing matching groove The inner side walls of the grooves are pressed against each other, and the outer ring of the outer bearing is connected with the casing. The casing is provi...

Embodiment 2

[0023] Embodiment 2: The basic structure and implementation of this embodiment are the same as those of Embodiment 1, and the difference is: Figure 2 to Figure 6 As shown in , the hood includes a main hood body 11, a lower hood convex cap 12 that is arranged on the main hood body and protrudes outward, and a hood air inlet 13 is provided on the lower hood convex cap. The moving impeller includes an impeller body and a lower ring rim 27 of the impeller. The lower ring rim of the impeller is provided with an impeller air inlet, the impeller air inlet is communicated with the hood air inlet, and the lower hood convex cap is provided with a wind hood sealing ring 14. The lower ring edge of the impeller and the air hood sealing ring are in contact with each other.

[0024] The lower end of the lower cover convex cap is curled inward to form a ring groove, the wind cover sealing ring is fixed in the ring groove, the wind cover sealing ring is provided with an annular sealing groove...

Abstract

The invention discloses a quickly-mounted motor. The quickly-mounted motor comprises an inducer, an impeller, a fan housing, a main case, a carbon brush, a rotor, a stator and a rotary shaft, wherein an inner bearing and an outer bearing are arranged on the rotary shaft; a bearing matching groove is formed in the inducer; the inner bearing is positioned in the bearing matching groove; the rotary shaft is connected with the inner ring of the inner bearing; the rotary shaft is connected with the inner ring of the outer bearing; the outer ring of the inner bearing and the inner side wall of the bearing matching groove are arranged in a mutual compressing manner; the outer ring of the outer bearing is connected with the main case; a plurality of case positioning holes are formed in the main case; the inducer is provided with multiple positioning columns; the positioning columns pass through the corresponding case positioning holes; and the fan housing and the main case are tightly clamped. The quickly-mounted motor has the beneficial effects that the main case and the fan housing are in direct tight fit, and the main case and the fan housing are guided and positioned through the positioning columns, so that the motor is mounted rapidly and conveniently, and high in matching precision; an extra bracket structure is not required; and the bearing is directly arranged in the bearing matching groove in the inducer, so that the accumulative error is reduced, the assembling precision is improved and the overall cost is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a quick-installed motor. Background technique [0002] Motors have been widely used and applied in current production and life. Generally speaking, the motor includes necessary structures such as stator, rotor, moving impeller, fixed impeller (wind guide wheel), casing, wind cover, etc. The wind cover and casing need to be assembled, and the rotating shaft of the rotor also needs to pass through the bearing. Provide auxiliary support. At present, the motor is mostly connected by screw assembly, and the bearing matched with the rotor is also installed in the form of an additional bracket. Although these methods can achieve assembly, the complexity of the structure is increased, and as the number of structures increases, the accuracy will also decrease accordingly (the cumulative error will increase). SUMMARY OF THE INVENTION [0003] In order to overcome the defici...
