Brief description of the drawings
Fig. 1 to Fig. 5 is the decomposed schematic diagram of the present invention；
Fig. 6 is the diagrammatic cross-section of the present invention.
Embodiment
Below only with the possible embodiment aspect of the embodiment explanation present invention, but and it is not used to limit the present invention and is intended to protect
Category, first give chat it is bright.
Please referring to Fig.1 to Fig. 6, those shown is hollow type planetary reducer provided by the present invention, it has a body 1,
The body 1 is equipped with a first gear 21, a second gear 31 and the central gear 32 set along same axis 11, wherein should
First gear 21 and the second gear 31 are located at the both sides of the body 1 respectively, and define and form primary speed-down mechanism 2 and two level subtracts
Fast mechanism 3.
Above-mentioned second gear 31 is an internal gear.Carefully say it, which is a cyclic structure body, and in the inner
Side surface is equipped with teeth portion.Accordingly, which is that the engagement for receiving other gears with its inner side connects.
Arrange in pairs or groups as shown in Figure 1, Figure 2 shown in Fig. 6, in this present embodiment, which is an internal gear, and in primary speed-down
In mechanism 2, the inner side of the first gear 21 is equipped with an at least drive gear 22, wherein each drive gear 22 is with a power input source
4 drivings.In this present embodiment, which includes four motors 41, this four motors 41 are incorporated into a module,
And a drive shaft 42 is stretched out respectively；On the other hand, the inner side of the first gear 21 is equipped with four drive gears 22, corresponds to respectively
A drive shaft 42 is connected, thereby drives each drive gear 22 to rotate.And each drive gear 22 is connected to a travelling gear
23, and each travelling gear 23 is connected to the first gear 21, wherein the travelling gear 23 and the first gear 21 distinguish pivot
Arranged on the body 1, thereby when motor 41 drives the drive gear 22 to rotate, by the transmission of the travelling gear 23, then this
One gear 21 rotates therewith.Wherein in this present embodiment, the number of teeth of the drive gear 22 is less than the number of teeth of the travelling gear 23, and
The number of teeth of the travelling gear 23 is also less than the number of teeth of the first gear 21, and therefore, the rotating speed that motor 41 exports will obtain two herein
Secondary deceleration.
As described above, the present embodiment is with four motors 41 in primary speed-down mechanism 2 while drives, then compared to known
With the gear reducer of motor driving, driving torque of each motor 41 when rotating can be reduced, and then is reduced when starting and operating
When energy consumption.On the other hand, it is arranged on travelling gear 23 of the number of teeth between the drive gear 22 and the first gear 21 upper
State therebetween, also make the drive gear 22 can relatively low driving torque drive the travelling gear 23, compared to the sliding tooth
For wheel 22 directly drives the first gear 21, the effect for reducing energy consumption can reach.
But above-mentioned first gear can also form the structure kenel of external gear as shown in Figure 3 in another embodiment.
As shown in the figure, first gear 21B is equipped with teeth portion in its outer circumferential side, and engages connection with its outer circumferential side with other gears, and it is same
The effect of sample is up to foregoing primary speed-down mechanism 2.
Hold, as Fig. 4, Fig. 5 arrange in pairs or groups shown in Fig. 6, in two reduction gear 3, which is located at second tooth
The inner side of wheel 31, and it is arranged on same plane with the second gear 31；Wherein connected with reference to Fig. 2, the central gear 32 with a connection piece 5
The first gear 21 is connected to, is thereby solidified as a whole and rotates synchronously with the first gear 21.In this present embodiment, the connector 5
With a connecting portion 51 extended along the axis 11, and one end of the connecting portion 51 is connected to the first gear in expansion shape
21.The central gear 32 is connected with least two planetary gears 33, in this present embodiment, planetary gear as shown in Figure 4, Figure 5
33 quantity is four, and each planetary gear 33 is connected to the second gear 31.Wherein the second gear 31 is fixed on
The body 1, since fixed state is presented in it, therefore each planetary gear 33 is subject to the drive of the central gear 32, then produces
Detour the action of the central gear 32.And each planetary gear 33 is to be arranged in an output 6, it is carefully sayed, each planetary gear 33
Axle center is sentenced a fixing piece 61 and is worn, and is fixed in the output 6, thereby, when planetary gear 33 produce as previously mentioned around
During the rotation of the row central gear 32, then the synchronous drive output 6 rotates；The output 6 can connect an external device (ED) (figure again
In do not show), you can formed an output terminal and drive the external device (ED) rotate.
In the action of above-mentioned two reduction gear 3, as shown in fig. 6, due to the central gear 32 it is coaxially connected in this first
Gear 21, therefore its rotating speed is equal with the first gear 21, that is, adopt as heir the deceleration result of primary speed-down mechanism 2.Then, by row
The configuration of star gear 33, makes rotating speed be lowered again, that is, the planetary gear 33 detour central gear 32 rotating speed compared with the sun
The rotating speed of gear 32 is low.It is comprehensive it, the rotating speed of the final output 6 is by above-mentioned primary speed-down mechanism 2 and two reduction gear 3
Under effect, the rotating speed that will be exported less than motor 41.
In addition, being equipped with a hollow pipe fitting 7 in the body 1 of this gear reducer, its inside has an accommodating space 71, for accommodating
Wire rod, such as electric wire, tracheae etc.In this present embodiment, which is arranged in the connecting portion 51 of the connector 5, it prolongs
It is also overlapping with the axis 11 to stretch direction.Set the hollow pipe fitting 7 to house wire rod here, then have and make gear reducer inner space match somebody with somebody
The effect of optimization is put, can effectively reduce the occupancy volume of gear reducer entirety, with the purpose minimized up to product.
