Title:
FLOATING GEAR SET, SPEED CHANGE DEVICE AND WIND GENERATING SET
Document Type and Number:
WIPO Patent Application WO/2023/206943
Kind Code:
A1
Abstract:
A floating gear set, a speed change device and a wind generating set, wherein the floating gear set comprises a self-aligning shaft assembly and two gears; two ends of the self-aligning shaft assembly in the axial direction are respectively inserted into the two gears; the self-aligning shaft assembly comprises a shaft body and a self-aligning member; the shaft body is in limit connection with the two gears in the circumferential direction by means of the self-aligning member; the shaft body radially swings, by means of the self-aligning member, relative to the two gears. According to the solution, the self-aligning shaft assembly can radially swing relative to the two gears, and in this way, the two gears can be misaligned with each other in the radial direction and can be in a connected state in which the two gears can float in the radial direction, so that a transmission path of a torque can be conveniently changed, so as to better realize torque distribution, and the torque density of a planetary gear mechanism can be improved especially when the solution is applied to the planetary gear mechanism.
