GEAR SPEED CHANGE DEVICE, TRANSMISSION MECHANISM, AND WIND GENERATING SET
Document Type and Number:
WIPO Patent Application WO/2023/173623
Kind Code:
A1
Abstract:
A gear speed change device. The gear speed change device comprises a first planetary gear train (100). The first planetary gear train (100) comprises a first ring gear (101), a first planetary carrier (102), first planetary gears (103), a solar idle gear (104), and a planetary idle gear (105). The planetary idle gear (105) and the first planetary gears (103) are all mounted on the first planetary carrier (102); each first planetary gear (103) comprises a pinion (103a) and a large gear (103b) coaxially connected to the pinion (103a); the planetary idle gear (105) and the pinion (103a) are both engaged with the inside of the first ring gear (101) and are both engaged with the outside of the solar idle gear (104); the pinion (103a) can float along the radial direction thereof relative to the first planetary carrier (102), and the maximum radial floating amount of the pinion (103a) is greater than the maximum radial floating amount of the planetary idle gear (105); and the large gears (103b) of at least two first planetary gears (103) are arranged in a staggered manner in the axial direction, and projections thereof on a plane perpendicular to the axial direction overlap with each other. The gear speed change device has a relatively high torque load density, and can give consideration to a small volume, a large transmission speed ratio and a high torque load capability.
