Title:

VEHICLE DRIVE DEVICE AND PRODUCTION METHOD FOR PLANETARY GEAR MECHANISM

Document Type and Number:

WIPO Patent Application WO/2023/190424

Kind Code:

A1

Abstract:

The number of teeth of all gears (36, 37) that mesh with a first gear part (34) and a second gear part (35) in a planetary gear mechanism (30) is a value for which the remainder is N when divided by 2N. 2N planetary gears (33) include N first-type planetary gears (33X) and N second-type planetary gears (33Y). The first-type planetary gears (33X) and the second-type planetary gears (33Y) differ in the phase of gear teeth (35a) of the second gear part (35) with respect to the gear teeth (34a) of the first gear part (34). The first-type planetary gears (33X) and the second-type planetary gears (33Y) are disposed alternately along the circumferential direction.
