The model utility content
The purpose of this utility model is to propose a kind of being convenient to and processes, and can conveniently control the planetary gear train outer gearing lubrication system of spray angle.
for achieving the above object, the utility model is taked following technological scheme: this planetary gear train outer gearing lubrication system comprises planet carrier, planet wheel, sun gear and gear ring, an end that approaches with planet wheel on planet carrier is provided with the axially front oil transportation channel corresponding with planet wheel, the import of front oil transportation channel is on the end face of planet carrier, the outlet of front oil transportation channel is on the chamber wall of planet carrier, on the wall of the chamber of planet carrier and before corresponding every, the outlet port of oil transportation channel is equipped with an injection nozzle carrier, be provided with rear oil transportation channel in injection nozzle carrier, nozzle is equipped with in the outlet port of rear oil transportation channel, the outlet of the import of the rear oil transportation channel of injection nozzle carrier and the front oil transportation channel of planet carrier is joined.
Described injection nozzle carrier top is provided with towards the inclined-plane of planet wheel and sun gear engagement place, and the import of the rear oil transportation channel of injection nozzle carrier is arranged on the bottom surface of injection nozzle carrier, and the outlet of rear oil transportation channel is arranged on the inclined-plane.
By two bolts hole of two bolts bottom injection nozzle carrier, injection nozzle carrier is fixed on planet carrier.
The inclined-plane of described injection nozzle carrier is provided with tapped hole, and nozzle threads is connected in tapped hole.
Described nozzle is fan nozzle, and the spray angle of nozzle is 90 °.
The utility model arranges injection nozzle carrier, avoid as far as possible the planet carrier deep hole processing, injection nozzle carrier and planet carrier can adopt different materials, reduced difficulty of processing, reduced the risk that planet carrier is scrapped, angle of inclination, inclined-plane that can be by changing injection nozzle carrier and inclined-plane penetrate on the engaging position of sun gear and planet wheel towards the spray angle of angle and nozzle the lubricant oil that sprays by nozzle
