Document Type and Number:
WIPO Patent Application WO/2023/176179
Kind Code:
A1
Abstract:
Provided is a lubrication system (10) for a planetary gear mechanism (11) including a sun gear (22) having helical teeth (22b), the lubrication system (10) comprising a supply channel (61), a supply channel (62), and a controller (15). The supply channel (61) is located on one of both sides of the sun gear (22) in a direction along a rotation axis (O) of the sun gear (22) and is formed toward tooth surfaces (22a) of the sun gear (22). The supply channel (62) is formed on the other one of the both sides of the sun gear (22) and is formed toward the tooth surfaces (22a) of the sun gear (22). The controller (15) switches the discharge of a lubricant to the tooth surfaces (22a) of the sun gear (22) between the supply channel (61) and the supply channel (62) on the basis of the direction of rotation of the sun gear (22).
