Description
Technical field
The utility model is related to motor, more particularly to a kind of rotor 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 that the part for driving and rotating by outer rotor is driven by outer rotor
The part for moving and rotating（Part hereinafter referred to as to be driven）Between connection, rotor base can be designed.The structure of rotor base is one
Rotor understructure, including support disk are planted, the center of the support disk is provided with rotating shaft connecting hole, and support disk is provided with
It is some along disk it is circumferentially distributed and be looped around rotating shaft connecting hole periphery connecting hole.Rotating shaft is separately mounted to by two during assembling
Bearings in the big footpath section of two of base are located in rotating shaft connecting hole logical rotor in stator base and after the stretching of one end
Base is fixed together.In use, part to be driven by bolt also cross same spiral shell after the through hole and connecting hole of driven member
Mother is joined together to realize connection.Therefore the rotor base of existing motor is reserved larger with being needed between the main body of motor
Gap can realize the connection of driven member（The small space for then not accommodating nut or bolt head in gap）, so as to cause
The structural compactness of motor is poor.
Utility model content
The utility model provide it is easy to maintenance after a kind of connecting hole is damaged and when using with need not be peace between motor body
The rotor understructure of preset clearance is filled, solving existing motor needs between main body of the rotor 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 rotor understructure, including branch are held round
Disk, the center of the support disk is provided with rotating shaft connecting hole, and the support disk is provided with some circumferentially distributed and circular along disk
Connecting hole in rotating shaft connecting hole periphery, it is characterised in that thread bush is equipped with the connecting hole, the thread bush is provided with resistance
The gib head that only bolt sleeve is extracted out of described connecting hole, the gib head is located at when support disk is used close to the one of motor body
Side.By setting the thread bush with gib head in connecting hole, the end of thread of bolt penetrates rear thread from part to be driven during connection
It is connected in screw thread when can be achieved part to be driven being fixed on rotor without generation obscission, because bolt is straight
Connect and be threaded in rotor base, therefore rotor base is with the gap between motor body without reserved installation.And work as
Only need to change thread bush during damage, and it is existing need to change whole stator base after connecting hole is damaged, therefore this skill
It is convenient when art scheme is repaired.
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, flange of the outer rim provided with support motor housing of the support disk, the flange is same to support disk
Between formed gear connect step.Convenience when same motor housing is attached can be improved.
Preferably, the rotating shaft connecting hole towards one end of motor body be provided with bulge loop, the flange, support disk and
Coil is formed between bulge loop and avoids space.Compact type can further be improved.
The utility model tool has the advantage that：With part to be driven junction produce damage when it is easy to maintenance；It can realize
The compact assembling of motor；Convenience when connecting part to be driven is good.
