Please refer to Fig. 1-3, wherein Fig. 1 is the perspective view of the utility model toothed gearing electric motor；Fig. 2 is the utility model
The part isometric structural exploded view of toothed gearing electric motor；Fig. 3 is another visual angle part isometric of the utility model toothed gearing electric motor
Structural exploded view.The toothed gearing electric motor includes: motor 1, the reduction gearbox 2 being sequentially connected respectively with the motor 1 and rotation
Encoder 3.
The motor shaft 12 that the motor 1 extends including motor body 11 and respectively with the motor body 11, as defeated
Out.In present embodiment, motor shaft 12 is extended by the opposite end of the motor body 11 simultaneously respectively.
The reduction gearbox 2 includes shell 21 and the deceleration unit 22 being installed in the shell 21.
It is in hollow structure in the shell 21, can be structure as a whole can also be separate structure, for example the shell includes
One end is opening-like, facilitates the installation of the deceleration unit 22.
The deceleration unit 22 includes the starting tooth that the motor shaft 12 is coaxially disposed and be fixed on the motor shaft 12
Wheel 221 and the 221 meshed gears group 222 of starting gear, wheel shaft 223, upper mounted plate 224, bottom plate 225, output gear
Wheel 226, output shaft 227 and dagger 228.
Fixed plate 224 is oppositely arranged with the bottom plate 225 and forms fixed connect by the dagger 228
It connects.The gear set 222 is assemblied between fixed plate 224 and the bottom plate 225 by the wheel shaft 223.Institute
State output gear 226 be arranged be fixed on the output shaft 227 close to fixed plate 224 one end and with the gear set
222 engagements.
The gear set 222 is included at least with the one-stage gear group 2221 that engages of starting gear 221 and with described one
The secondary gear group 2222 that grade gear set 2221 engages.
The one-stage gear group 2221 by a wheel shaft 223 be supported in fixed plate 224 with it is described lower solid
Between fixed board 225, the one-stage gear group 2221 includes the coaxial folded multiple one-stage gears set.
The secondary gear group 2222 by a wheel shaft 223 be supported in fixed plate 224 with it is described lower solid
Between fixed board 225, the secondary gear group 2222 includes the coaxial folded multiple secondary gears set.
In present embodiment, 228 quantity of dagger is at least three and spacer ring is set to the week of the bottom plate 225
The shell 21 of edge, the dagger 228 and reduction gearbox 2, which is spaced, to be arranged, and is equivalent to form an invisible shell structure for receiving
Hold the deceleration unit 22.
Specifically, each dagger 228 includes being fixed between fixed plate 224 and the bottom plate 225
Dagger ontology 2281 and be sheathed on the dagger ontology 2281 and can relative to the dagger ontology 2281 rotate dagger set
2282.The outside of dagger set 2282 offer stable tooth 2283, the gear set 222 and/or the output gear 226 with
The stable tooth 2283 engages.The setting of the structure so that the gear set 222 and/or the output gear 226 pass through it is described
Dagger ontology 2281 is limited, and prevents from contacting generation frictional noise with shell 21, while by dagger set 2282 and surely
2283 structure of fixed tooth assists the gear set 222 and the output gear 226 to rotate in fact, so that it is single to effectively increase the deceleration
The stability and reliability of member 22.
More preferably, three daggers 228 are arranged at equal intervals, and certainly, the quantity of the dagger 228 is not limited to this.
When to obtain different reduction ratio, different speed can be obtained by increasing the gear quantity of gear set 222

In present embodiment, the dagger ontology 2281 of the wheel shaft 223 and the dagger 228 is retractable structure,
It for example is adjustable and retractable bar.So as to by itself adjusting each length needed for oneself, woth no need to be replaced；When dagger set
When 2282 length is not enough adapted to increased gear realization engagement, it is only necessary to be individually replaced dagger set 2282.Further drop
Low its structure is complicated property and reduce its production cost.
Specifically, the starting gear 221 is made of metal material, the one-stage gear group 2221 and the secondary gear
Group 2222 is made of plastics.On the one hand the wear-resisting property for improving starting gear 221, increases service life, another aspect plastics system
At gear structures at different levels mitigate toothed gearing electric motor overall weight, lightweight.Certainly, material is not limited to this,
It can all be made of metal material, or be all made of plastic material.
The rotary encoder 3 is arranged the one end close to the bottom plate 225 for being fixed on the output shaft 227.This
The rotary encoder 3 in embodiment is the common rotary encoder in market comprising encoder 31 and magnet ring 32.
The encoder 31 drives magnet ring 32 after being powered, magnet ring 32 divides positive and negative to pole, issues magnetic positive and negative anodes frequency in rotation, is sent to
Encoder 31 and by the exportable moment basis pulses of encoder 31, it can be achieved that pay close attention to the real time monitoring of revolving speed, make product
Application range is more extensive.
Toothed gearing electric motor provided by the utility model setting upper mounted plate and bottom plate, and by fixed plate with
The bottom plate is fixedly connected by the dagger, the gear teeth group be set to fixed plate and the bottom plate it
Between and with it is described started to walk wheel engage, the output gear is engaged with the gear teeth group again, collectively forms deceleration unit, the structure
So that the deceleration unit is not secured on shell, when needing the adjustment of a variety of reduction ratio, without the knot for changing shell
Structure, it is only necessary to increase the length of the dagger and the wheel shaft, fast to increase the number of gear teeth of gear teeth group, to realize
