Abstract
The utility model relates to an output mechanism of a gearbox of a wind power generator for yawing gearboxes, which comprises an output planet carrier and an output shaft. The output mechanism is characterized in that the output planet carrier is fixed integrally with the output shaft, the output planet carrier is mounted on a box body via the support of two tapered roller bearings, the output shaft penetrates an end cover of the end portion of the box body, the rear portions of the tapered roller bearings are equipped with circular nut stop washers and circular nuts, the combination portion of the end cover and the circular nuts is equipped with an oil seal, and an output gear is connected with the end portion of the output shaft via a baffle plate and screw bolts. The output mechanism has the advantages that the output mechanism increases the stiffness of the output shaft or the output gear, and the circular nuts provide pre-tightening force for the tapered roller bearings, thereby prolonging the service life of the tapered roller bearings.
Description
Technical field
The utility model relates to a kind of output mechanism of gear-box, especially a kind of output mechanism that is used for the wind-driven generator wheel-box of Yaw gearbox.
Background technique
Utilize wind-power electricity generation to compare, have the free of contamination advantage of generating, compare with hydroelectric power with traditional thermal power generation, have that the capital construction cost is low, floor space is little, maintaining is advantage easily, and for large-scale hydroelectric power plant, also there is certain potential safety hazard in storage reservoir to the downstream easily.Yaw gearbox at wind-driven generator is the special gear box that wind-driven generator selects to aim at or depart from wind direction, in Yaw gearbox, a fixing general spheric roller bearing and roller roller bearing of adopting of the bearing of output shaft, in the use often because of the not enough using effect and the adjustment angle of influence of rigidity of bearing.
Summary of the invention
The purpose of this utility model is: at the fixing not enough practical problem that influence using effect and adjustment angle of the rigidity of the bearing of output shaft in the Yaw gearbox, provide a kind of output mechanism of Yaw gearbox for wind power generator of new Yaw gearbox.
The purpose of this utility model is achieved in that a kind of output mechanism of wind-driven generator wheel-box, comprises output planetary frame, output shaft, it is characterized in that:
A) output planetary frame and output shaft are solidified as a whole;
B) the output planetary frame supports by two tapered roller bearings on the output shaft and is installed on the casing, and output shaft passes the end cap of casing end, and the tapered roller bearing rear portion is provided with round nut lock washer and round nut, and end cap and round nut connecting part are provided with oil sealing;
C) output gear is connected with output shaft end with bolt by baffle plate.
