Summary of the invention
The purpose of this utility model is: at existing wind driven generator yaw and variable propeller gearbox planet wheel supporting structure complexity, and adopt when completely adorning needle bearing, the inside and outside raceway that planet wheel shaft cylindrical and planet wheel endoporus are made needle roller all needs through hardening and grinding, practical problems such as assembling is bothersome provide a kind of supporting structure of new planet wheel.
The purpose of this utility model is achieved in that a kind of supporting structure of planet wheel, comprise: planet wheel shaft and bearing, it is characterized in that: an end of planet wheel shaft and the side plate of planet carrier are solidified as a whole and form the single wall integral planet carrier, and planet wheel shaft and side plate connecting part are transition shoulder; Bearing is a roller bearing, and the bearing inner race of each roller both sides is provided with rib in the bearing, and the bearing inner race between two ribs is the interior raceway of cylindrical roller, and bearing inner race places on the planet wheel shaft; The bearing inner race inboard is butted on transition shoulder, and the planet wheel shaft in the bearing inner race outside is provided with the circlip for shaft that places in the annular groove; The endoporus of cylinder planet wheel is the outer raceway of roller; Planet wheel carries out axially locating by the circlip for hole in the annular groove in the planet wheel endoporus, is provided with thrust washer between circlip for hole and the cylindrical roller.
In the utility model: described bearing is the single row roller bearing with single-row roller, or has the composite cylindrical roller bearing of at least two row rollers; Planet wheel carries out axially locating by the circlip for hole in the annular groove in the planet wheel endoporus in the cylindrical roller outside, is provided with thrust washer between circlip for hole and the cylindrical roller.。
In the utility model: the bearing pack that described bearing is combined to form side by side by two single row roller bearings at least, wherein: the bearing inner race inwall in occupying is butted on transition shoulder, and the planet wheel shaft that occupies the outer bearing inner race outside is provided with the circlip for shaft that places in the annular groove; Planet wheel carries out axially locating by the circlip for hole in the annular groove in the planet wheel endoporus between two single row roller bearings, is equipped with thrust washer between circlip for hole and the both sides cylindrical roller
Advantage of the present utility model is: compare with adopting the supporting structure of completely adorning needle bearing, because the planet wheel shaft outer surface does not need to harden and grinding, simplified production technology; Number of bearings significantly reduces, and is easy for installation; Can select suitable bearing to be used in combination according to actual conditions, select for use flexibly.
