Title:
GEAR SHIFTING DEVICE, TRANSMISSION MECHANISM, AND WIND TURBINE GENERATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/226266
Kind Code:
A1
Abstract:
A gear shifting device, comprising a first planetary gear train (100). The first planetary gear train comprises a first ring gear (101), a first planet carrier (102), a first planet gear (103), a sun idler (104), and a planet idler (105); the planet idler and the first planet gear are both installed on the first planet carrier; the first planet gear comprises a pinion (103a) and a bull gear (103b) coaxially connected to the pinion; the planet idler and the pinion are both meshed with the inside of the first ring gear and are both meshed with the outside of the sun idler; the pinion can float in the radial direction relative to the first planet carrier; an input shaft (110) is further provided; one end of the input shaft is connected to the first ring gear. The gear shifting device has a high torque load density, and can achieve a small volume, a large transmission ratio, and a high torque load capacity.
