Progress, it is also higher and higher to the performance requirement of planetary transmission, therefore Planetary Gear Transmission is by Spur Gear Driving
Helical gear Transmission is developed into, thus further increases the difficulty of processing of helical teeth ring gear.
Utility model content
Low production efficiency, the low essence that processing for ring gear present in existing planetary driving device and planet carrier faces
Degree, high cost problem, the utility model provides a kind of planetary reduction gear transmission device, with overcome the deficiencies in the prior art.
A kind of planetary reduction gear transmission device of the utility model, including input shaft, output shaft and compound planet gear axis,
One end of the output shaft is fixed by clutch shaft bearing, the other end of output shaft be provided be connected as one with output shaft
One gear, is fixed with second bearing in the mounting groove of first gear end, and one end of input shaft passes through second bearing and output
Axis is rotatablely connected, and the other end of input shaft is fixed by 3rd bearing, and second gear is provided with input shaft；Duplex planet tooth
The both ends of wheel shaft are fixed by a pair of 4th gear, and the 3rd gear and the 4th tooth are respectively arranged with compound planet gear axis
Wheel, the second gear on the input shaft are engaged with the 4th gear on compound planet gear axis, while the on output shaft
One gear is engaged with the 3rd gear on compound planet gear axis.
Further, the axial line of the input shaft and output shaft is concentric.
Further, bearing holder (housing, cover) is cased with the input shaft, 3rd bearing is fixedly mounted on bearing holder (housing, cover).
By adopting the above-described technical solution, the utility model has the advantage of：The utility model passes through external gear driving
Mode realizes Gear Planet Transmission, without ring gear and planet carrier, makes the device internal structure more compact, contour structures smaller, and
After ring gear is changed over external gear, the difficulty of processing of gear is reduced, and can guarantee that the machining accuracy of gear, improves production effect
Rate, reduces production cost.In addition, the function of planet carrier is engaged by compound planet gear axis with the gear on output shaft come real
It is existing, and be all external tooth wheel construction, tooth craftsmanship processed is preferable, and production efficiency is high, and precision can also ensure that reduction is produced into well
This.

Embodiment
It is right with reference to the accompanying drawings and examples in order to make the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
The embodiment of the utility model：The structure diagram of planetary reduction gear transmission device as shown in Figure 1, including input shaft 1,
Output shaft 2 and compound planet gear axis 3, one end of the output shaft 2 is fixed by clutch shaft bearing 8, in the another of output shaft 2
End is provided with the first gear 7 being connected as one with output shaft 2, and the second axis is fixed with the mounting groove of 7 end of first gear
6 are held, one end of input shaft 1 is rotatablely connected by second bearing 6 and output shaft 2, the axial line of the input shaft 1 and output shaft 2
With one heart；The other end of input shaft 1 is cased with bearing holder (housing, cover) 12, and input shaft 1 is solid by the 3rd bearing 4 being fixedly mounted on bearing holder (housing, cover) 12
It is fixed, second gear 5 is provided with input shaft 1；The both ends of compound planet gear axis 3 are fixed by a pair of 4th gear 9, double
Be respectively arranged with the 3rd gear 10 and the 4th gear 11 in connection planetary gear shaft 3, the second gear 5 on the input shaft 1 with
The 4th gear 11 on compound planet gear axis 3 engages, while on the first gear 7 on output shaft 2 and compound planet gear axis 3
The 3rd gear 10 engage.
During work, input shaft 1 rotates and drives 11 turns of the 4th gear on compound planet gear axis 3 by second gear 5
Dynamic, so as to drive compound planet gear axis 3 together to rotate, when compound planet gear axis 3 rotates, compound planet gear axis 3 passes through
3rd gear 10 driving first gear 7 rotates, so as to drive output shaft 2 together to rotate.When the first gear 7 on output shaft 2 is solid
