Description
Technical field
The utility model is related to motor, more particularly to a kind of motor stator understructure.
Background technology
Motor installs the position relationship of rotor and stator, is divided into inner rotor motor and external rotor electric machine.Wherein external rotor electric
Machine is the motor that stator is arranged on to internal rotor.In order to realize the installation of external rotor electric machine, stator base can be designed.Stator bottom
The structure of seat is to include rotating shaft support pipe, and the inner peripheral surface two ends of rotating shaft support pipe are respectively provided with the big footpath section of a spring bearing, turn
One end of axle support tube is provided with mounting seat, and mounting seat is provided with mounting hole.Rotating shaft is separately mounted to base by two during assembling
Two big footpath section on bearings are in rotating shaft support pipe and rotating shaft support pipe is stretched out in one end, outer rotor passes through rotor base
It is connected in rotating shaft.In use, motor is fed through same spiral shell after the through hole of the part of mounting hole and fixed motor by bolt simultaneously
Mother is joined together to realize and installed.Therefore the stator base of existing motor is reserved larger with being needed between the main body of motor
Gap can realize installation（The small space for then not accommodating nut or bolt head in gap）, so as to cause the structure of motor
Compactedness is poor.
Utility model content
The utility model provide it is easy to maintenance after a kind of mounting hole is damaged and when using with need not be peace between motor body
The motor stator understructure of preset clearance is filled, solving existing motor needs between main body of the stator base with motor extremely
The problem of few reserved gap for accommodating nut can realize installation.
Above technical problem is solved by following technical proposal：A kind of motor stator understructure, including rotating shaft branch
Stay tube, the inner peripheral surface two ends of the rotating shaft support pipe are respectively provided with the big footpath section of a spring bearing, the one of the rotating shaft support pipe
End is provided with mounting seat, and the mounting seat, which is provided with mounting hole, the mounting hole, is equipped with thread bush, and the thread bush is provided with resistance
The gib head that only bolt sleeve is extracted towards the direction away from rotating shaft support pipe out of described mounting hole.By setting buckle in mounting hole
The thread bush of head, during connection the end of thread of bolt penetrated from the part for installing motor rear thread be connected in screw thread it is i.e. achievable
Motor is carried out to install fixed without producing obscission, because bolt is directly threadedly attached on stator base, therefore
Stator base is with the gap between motor body without reserved installation.And only need to change thread bush when damaged,
And need to change whole stator base after existing damage, therefore it is convenient when being repaired after the technical program damage.
Preferably, approaching face is installed in the outer end of the big footpath section provided with bearing.It is convenient during bearing to be fitted into.
Preferably, the inner peripheral surface of the thread bush is provided with the circumferentially distributed groove that at least twice threadingly cover, institute
State groove and threadingly cover screw thread axially through thread bush.Supplement.
Preferably, the depth for the radial direction that the groove threadingly covers is formed between being more than the screw thread of the thread bush
The depth of thread groove.Dirt can preferably be accommodated.
Preferably, the wall of the groove is provided with raised sword.Supplement.
Preferably, the outer peripheral face of the rotating shaft support pipe is provided with iron core limited step, the iron core limiting stand component level
In on one end provided with mounting seat of rotating shaft support pipe.It can effectively prevent stator core from producing movement.
The utility model tool has the advantage that：The junction of the part of same fixed motor produces easy to maintenance during damage；Energy
Enough realize the compact assembling of motor；Convenience when installing motor is good.
