Moral exists《Mechanical problem》In, the problem of just elaborating with bronze or cast iron gear transmission rotary motion.In the famous scholar of Greece is sub-
Shi Duode and Archimedes studied gear, the famous inventor's Guti Scipio Africanus of Greece this on plectane work edge of table
Pin is plugged evenly, it is engaged with pin wheel, and he is applied to this mechanism in quarter leakage.This is approximately the thing of B.C. 150 years.
B.C. 100 years, the inventor He Lun of sub- people from Lishan Mountain invented odometer, and gear has been used in odometer.1st century of Christian era
When, gear drive is also using on the Waterwheel-type flour mill that the master builder Bi Duobisi in Rome makes.To 14th century, start
Gear is used on clock and watch.
The gearratio of conventional gears group is generally relatively low, while the kind of drive is single, it is impossible to accomplish transmission integrated.
Utility model content
The purpose of this utility model is and one proposed in order to solve the shortcoming that transmission efficiency present in prior art is low
Plant high transmission ratio planetary gear.
To achieve these goals, the utility model employs following technical scheme：A kind of high transmission ratio planetary gear, bag
Include and be provided with damping shell, and damping shell on the outside of planetary gear body, planetary gear and sun gear, the planetary gear body
Inwall on be provided with external toothing, the inner hub location of the planetary gear body solar energy be installed, and sun gear
Sun gear main shaft is installed, the upper surface center position of the sun gear passes through planet carrier and planet at right center position
Wheel drive connection, and be provided with the right side of planetary gear planetary gear auxiliary rotating shaft, the planetary gear body by bolt with
Gear-box is threadedly coupled, and gear-box at bolt link position with being provided with fixing nut.
It is used as further describing for above-mentioned technical proposal：
Four corners of the damping shell are mounted on bolt fixing hole.
It is used as further describing for above-mentioned technical proposal：
Output revolving shaft is installed at the Left-side center position of the sun gear.
It is used as further describing for above-mentioned technical proposal：
The pressure angle of the planetary gear and sun gear is the identical number of degrees.
In the utility model, relative to conventional gears group, novel planetary gear by gear train be integrated into sun gear and
Planetary gear, and connected by planet carrier, the structure for realizing conventional gears group simplifies so that gear train was manufactured in industrial production
Cheng Zhong, it is more convenient to use, also beneficial to the maintenance work in later stage, meanwhile, the outside of novel planetary gear is provided with damping
Shell, there is also mounted gear-box so that in the case that gear train is protected by dual shock absorption on the outside of damping shell, few
There is the situation of gear loose, gear train work failure rate greatly reduces, finally, the sun gear of novel planetary gear
The identical number of degrees are fabricated to the pressure angle of planetary gear, it is ensured that be not in the situation of corner cut in Meshing Process of Spur Gear, greatly
The big service life for improving gear train.
