CONGEGNO LUBRIFICATORE PER SUPPORTI PER RUOTA SATELLITE

摘要

A planetary-gear assembly has a planet gear carrier constituted by a pair of axially spaced carrier plates bridged by a plurality of axially extending pins each carrying a respective planet gear by means of a respective bearing. An adjacent member rotatable independently of the planet carrier forms with the planet carrier an annular chamber centered on the axis. This annular chamber is closed axially by the one carrier plate and the adjacent member and is closed radially outwardly by a seal ring engaging between this one carrier plate and the adjacent member. Each of the pins is formed with a throughgoing passage opening axially into this annular chamber and radially at the respective bearing. Liquid lubricant is fed to the chamber radially inwardly of these passages so as the assembly rotates the lubricant will be forced radially outwardly, filling the radial outward portion of the chamber and forcing the lubricant through the passage to the bearings.
