Title:
LUBRICATION DEVICE FOR PLANETARY GEAR
Document Type and Number:
WIPO Patent Application WO/2006/100963
Kind Code:
A1
Abstract:
When an output shaft (l2) and a thrust bearing (45) are rotated, centrifugal force is applied to lubrication oil that flows out from an oil hole (65a). Then the lubrication oil passes, while being guided by a race (53) and an output shaft flange (l2b) and lubricating the thrust bearing (45), through a tip gap (g) of a race outer diameter section (53c) or a cutout (53d), and substantially the entire amount of the oil is led to an annular groove (51). The oil further goes through a communication hole (52) and oil holes (49, 46, 50) and is fed to a pinion support section (41).
