Title:
PLANETARY GEAR MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/176180
Kind Code:
A1
Abstract:
In this planetary gear mechanism (11), a plurality of pinion shafts (24) rotatably support a plurality of planetary gears (23) having helical teeth (23b). A first carrier disk (31) supports respective first ends (241) of the plurality of pinion shafts (24). A second carrier disk (32) supports respective second ends (242) of the plurality of respective pinion shafts (24). A plurality of carrier columns (33) are disposed between the planetary gears (23) adjacent to each other in a circumferential direction (H), and connect the first carrier disk (31) and the second carrier disk (32). The carrier columns (33) each have: a first end section (331) connected to the first carrier disk (31); and a second end section (332) connected to the second carrier disk (32). The carrier columns (33) are disposed so that the interval (d1) between the carrier columns (33) and the planetary gears (23) disposed on the leftward circumferential direction H1 of the carrier columns (33) is greater on the first end section (331) side than on the second end section (332) side.
