The corresponding oilhole of oil-out of the independent oil pocket of box second.
It is an advantage of the current invention that：Because the present invention is that planet carrier is provided with oil collection box, two independences are provided with oil collection box
Oil pocket, their oil-in is located in face of in the box wall of planet carrier direction of rotation side by side, and the oil-out of the first independent oil pocket sets
On the top cover of oil collection box, oil-out and the oil leab in planetary gear bearing pin of the second independent oil pocket are linked up, its lubricating system
Completely using in the planet carrier course of work, oil collection box is two independent oil pocket supplemental lubrications by two oil-ins when oil sump
Oil, and by the oil-out of the first independent oil pocket lubrication is provided for planet carrier spring bearing in operation, by the second independent oil pocket
Oil-out provide lubrication for planet wheel support bearing by the oil leab in bearing pin, lubricant passage way is not related to external pump, oily
It is not association of activity and inertia in road position, as long as there is enough lubricating oil in oil sump, each spring bearing of planet circular system just can be obtained yet
Reliable lubrication.Present configuration is compact, and long service life, fault rate is low, even if needing repairing, safeguards also very convenient.
