The utility model provides a motor assembly directly makes the off -axial into 4mm, then " beat the muscle " on 4mm's excircle, neither influences bearing installation, makes the bonding strength of axle and gear have promotion by a wide margin moreover, has effectively avoided the problem that the synchronizing wheel radially skidded.
Description
Technical field
This utility model is related to design of electrical motor and manufacturing technology field, especially a kind of motor general assembly.
Background technology
AC brushless electric machine is a kind of cage motor not having carbon brush, instead of traditional brush motor, which removes electricity
Brush, the electric spark that the most directly change produces when being exactly and operating without brush motor, thus greatly reduce electric spark pair
The interference of remote-control radio electric equipment；And noise when running is low, smooth movements.
But the axle of existing structure 5mm external diameter joins the synchronizing wheel of 5mm endoporus, for the installation (brearing bore of bearing
5mm), (doing about one has blade mould, and axle is put in mould, then utilizes punch press punching press " cannot to beat muscle " above axle
Matched moulds, can leave several roads impression after point mould, (being shaped like in gear hobbing, only tooth bar only has 4 ~ 8) on axle) or " rolling
Tooth ", but after playing muscle or gear hobbing above axle, diameter of axle increase about 0.1mm can be made, lead to bearing can not install, if do not processed,
Synchronizing wheel is made easily to produce radial direction skidding.
Utility model content
The technical problems to be solved in the utility model is: the axle in order to solve existing structure 5mm external diameter joins 5mm endoporus
Synchronizing wheel, for the installation (brearing bore 5mm) of bearing, above axle, " muscle cannot be beaten " (doing about one has blade mould,
Axle is put in mould, then utilizes Presser Dashing press-fitting mould, several roads impression can be left on axle after point mould, (be shaped like in rolling
Tooth, only tooth bar only have 4 ~ 8)) or " gear hobbing ", but after playing muscle or gear hobbing above axle, the diameter of axle can be made to increase 0.1mm, lead
Causing bearing can not install, if do not processed, making synchronizing wheel easily produce the problem radially skidded, this utility model provides one kind
Motor general assembly, axle external diameter is made into 4mm, then 4mm cylindrical on play muscle or gear hobbing, neither impact bearing is installed, and axle
With synchronizing wheel interference fit, beat muscle or gear hobbing structure makes the bond strength of axle and synchronizing wheel have significantly to be lifted, effectively keep away
Exempt from the problem that synchronous wheel radial skids.
This utility model solves its technical problem and be the technical scheme is that
A kind of motor general assembly, comprising: stator, front motor cover, motor rear cover, bearing, rotor and synchronizing wheel, described rotor tool
There is a rotating shaft,
Described front motor cover and motor rear cover are separately fixed at the front-end and back-end of stator, after described front motor cover and motor
Cover position corresponding with stator and be provided with insulating trip, described rotor is arranged in stator, bearing and electricity are passed through in the rotating shaft of described rotor
Machine protecgulum is fixedly connected with motor rear cover, a diameter of 4mm of the nearly front motor cover one end of described rotating shaft, and is arranged with synchronizing wheel, institute
Stating synchronizing wheel internal diameter is 4mm, has an anti-skid structure preventing synchronous wheel radial skidding, described anti-skid structure between described rotating shaft
For the gear hobbing structure that is arranged on axial plane or beat muscle structure.
Preferably, being provided with a corrugated gasket between the bearing of the nearly motor rear cover one end of described rotating shaft and motor rear cover.
The beneficial effects of the utility model are: a kind of motor general assembly that this utility model provides, and axle external diameter is made into 4mm,
Then 4mm cylindrical on play muscle or gear hobbing, neither impact bearing is installed, and axle and synchronizing wheel interference fit, plays muscle or rolling
Toothing makes the bond strength of axle and synchronizing wheel have significantly to be lifted, effectively prevent the problem that synchronous wheel radial skids.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
