Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Inner rotor motor or external rotor electric machine can be divided into according to the mode that this tooth difference driving motor exports.
Embodiment one
With reference to shown in Fig. 1, this tooth difference driving motor comprises stator 12, rotor 14, outside internal-gear 16, inner external tooth gear 18, output shaft 20 and a motor shell 22.This tooth difference driving motor can be driven by ac/dc.Moreover according to the set-up mode of this stator 12 with this rotor 14, this tooth difference driving motor can divide into synchronous machine and asynchronous machine again again.For example, in this synchronous machine, this stator 12 is coil and this rotor 14 is magnet; In this asynchronous machine, this stator 12 is coil and this rotor 14 is coil.
In the present embodiment, this tooth difference driving motor system illustrates for inner rotor motor.
This motor shell 22 forms an accommodation space 222.This accommodation space 222 holds this stator 12, this rotor 14, this outside internal-gear 16, this inner external tooth gear 18 and this output shaft 20.
This stator 12 is for generation one magnetic line of force.
This rotor 14 is in conjunction with this stator 12, and this rotor 14 still comprises plural magnet 142.This rotor 14 is subject to the traction (or claiming cutting) of this magnetic line of force, rotates with one first rotating speed.It should be noted that the wall unevenness of this rotor 14, the structure consistent with eccentric bushing.
This outside internal-gear 16 forms teeth 162 in plural number.This outside internal-gear 16 connects this rotor 14.When it should be noted that this rotor 14 rotates, this rotor 14 promotes this outside internal-gear 16, dynamically to change the shaft core position of this outside internal-gear 16.In the present embodiment, the plural spacing hole 242 on a shell 24 is inserted by the plural limited post 164 on this outside internal-gear 16, and through the wall unevenness of this rotor 14, allow these limited posts 164 be limited in these spacing holes 242 rotate, and reach this outside internal-gear 16 and can rotate in the mode of Under Asymmetrical.
This inner external tooth gear 18 forms the outer teeth 182 of plural number.This inner external tooth gear 18 is in conjunction with this outside internal-gear 16.When this outside internal-gear 16 rotates, in these, teeth 162 engage these outer teeth 182 partly.When it should be noted that this inner external tooth gear 18 rotates, the shaft core position of this inner external tooth gear 18 immobilizes.
The operating principle of this outside internal-gear 16 and this inner external tooth gear 18, be because the wall unevenness of this rotor 14 is even, cause in the process of rotating at this outside internal-gear 16, the shaft core position of this outside internal-gear 16 is also revocable, but does a small variation.Moreover these limited posts 164 of this outside internal-gear 16 are only limited in these spacing holes 242 and do small movement.In the process of movement, these outer teeth 182 of teeth 162 constantly mate in these of part.Due to the number of teeth between the outer teeth of teeth in these 162 and these 182 different (interior teeth are 22 teeth, and outer teeth are 20 teeth), this inner external tooth gear 18 is thus caused to be rotated in deceleration.This is rotated in deceleration is this second rotating speed being become this inner external tooth gear 18 by this first rotational speed decelerates of this outside internal-gear 16 of script.Exist between this first rotating speed and this second rotating speed a speed reducing ratio (reduction ratio) (speed reducing ratio=external tooth tooth tooth number/interior teeth and outer teeth tooth poor=20/ (22-20)=10), and this speed reducing ratio is defined as the number of teeth of these outer teeth 182 and the ratio of a number of teeth difference.This number of teeth difference is the difference between the number of teeth of teeth 162 in these and the number of teeth of these outer teeth 182.
Embodiment two
With reference to shown in Fig. 2, it is the exploded perspective view of the tooth difference driving motor of the utility model second embodiment.In fig. 2, this tooth difference driving motor has this stator 12 and this rotor 14 in the first embodiment, this motor shell 22 in this not clear display the 1st figure.This tooth difference driving motor separately comprises inner external tooth gear 26 and outside internal-gear 28 and an output panel 30.
In the present embodiment, this tooth difference driving motor system illustrates for external rotor electric machine.
This inner external tooth gear 26 forms the outer teeth 262 of plural number.This inner external tooth gear 26 connects this rotor 14.It should be noted that this rotor 14 promotes this inner external tooth gear 26, dynamically to change the shaft core position of this inner external tooth gear 26.In the present embodiment, this tooth difference driving motor more comprises a position-arresting disk 32, and this position-arresting disk 32 has plural spacing hole 322, and the plural limited post 264 on this inner external tooth gear 26 inserts these spacing holes 322.Due to, the wall unevenness of this rotor 14 is eccentric bushing structure, allows these limited posts 264 be limited in these spacing holes 322 and rotates, and reach this inner external tooth gear 22 and can rotate in the mode of Under Asymmetrical.
This outside internal-gear 28 forms teeth 282 in plural number.This outside internal-gear 28 is in conjunction with this inner external tooth gear 26.When this inner external tooth gear 26 rotates, these outer teeth 262 engage teeth 282 in these partly.When it should be noted that this outside internal-gear 28 rotates, the shaft core position of this outside internal-gear 28 immobilizes.
The operating principle of this inner external tooth gear 26 and this outside internal-gear 28 ditto described in, do not repeat in this.It should be noted that the definition of this speed reducing ratio of the present embodiment is modified to the number of teeth of teeth 282 in these and the ratio of a number of teeth difference.This number of teeth difference be these outer teeth 262 the number of teeth and in these teeth 282 the number of teeth between tooth poor.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
