Preferably, described shell comprises bottom surface and the sidewall that extends from the bottom surface, is provided with through hole in the bottom surface, and described clutch shaft bearing is installed in the described through hole.
Preferably, described stator is provided with the loading end that be used to place coil relative with described shell, and described loading end is provided with groove, and described second bearing places groove.
Preferably, described groove comprises first step and the first side wall that extends from first step, and described second Bearing Installation is on described the first side wall.
The present invention provides a kind of assemble method of vibrating motor in addition, and this assemble method may further comprise the steps: clutch shaft bearing, shell, second bearing, stator, rotation axis, rotor are provided; At first clutch shaft bearing is installed on the shell, with second Bearing Installation on stator; Rotation axis is connected with described rotor; With rotation axis and clutch shaft bearing riveted joint, rotation axis and shell are combined; With the other end and the riveted joint of second bearing of rotation axis, make rotation axis and stator combination together then; At last with shell and stator assembling.
Preferably, provide a bottom surface to have the shell of through hole, described clutch shaft bearing is installed in the through hole.
Preferably, provide one to be provided with loading end, and loading end is provided with the stator of groove, with described second Bearing Installation in described groove.
Preferably, provide the stator that is provided with the first side wall in the groove, with described second Bearing Installation on the first side wall of described groove.
Preferably, described rotation axis is pressed into a copper sheathing earlier, is connected with described rotor then.
Beneficial effect of the present invention is: owing on shell of the present invention and the stator bearing that plays the role of positioning is installed respectively, extended to greatest extent and located the effective length of rotor, rotor tilt is able to remarkable improvement, thereby the noise when effectively reducing electric motor starting and stopping, the improvement of rotor perpendicularity helps motor simultaneously and starts fast.
