It is fixedly connected between the terminal pad and fixed mount stated by hexagon socket head cap screw, described big sun gear outer ring is uniformly engaged with four
Major planet wheel, described major planet wheel position through mandrel one and coordinate installation by major planet frame and big ring gear, and described is small
Sun gear outer ring is uniformly engaged with three asteroid wheels, described asteroid wheel positioned through mandrel two and by asteroid frame and
Small internal gear coordinates installation.
The principle of this planetary gear assy is：Big sun gear and small sun gear is driven to rotate by hydraulic motor, wherein
Major planet wheel slow down increasing by big sun gear and turned round, small sun gear slow down increasing and turned round to asteroid wheel, its output torque
Reach 10000NM, transmission efficiency 92%.
In a kind of above-mentioned planetary gear assy, between described major planet wheel and mandrel one, asteroid wheel and core
Roller is respectively arranged between axle two.The design of roller can effectively reduce the friction between planetary gear and mandrel, increase it
Transmission efficiency.
In a kind of above-mentioned planetary gear assy, positioning sleeve is provided between described fixed mount and major planet frame.
The assembling of the decelerator can be made more accurate by positioning sleeve.
In a kind of above-mentioned planetary gear assy, pressure ring is provided between described spline housing and big sun gear.It is logical
Crossing pressure ring can make its structure compacter.
