The purpose of this utility model is achieved in that a kind of input end of wind-driven generator wheel-box, and in flange, fixedly connected with the casing of input end by bolt, it is characterized in that by flange by Bearing Installation for input shaft:
A) input shaft and flange connecting part are provided with oil sealing and bearing, and oil sealing is positioned on the input shaft of bearing front end, and described bearing is the deep groove ball bearing of monolateral band sealing surface, and its sealing surface is positioned at gear-box one side;
B) described flange is provided with lubricant grease inlet and the outer overflow lip of lubricant grease, also is provided with a pair of lubricated plug cock;
C) the outer overflow lip of described lubricant grease inlet and lubricant grease is linked up by the between centers crack between oil duct and oil sealing and the bearing; The gear cavity of described lubricated plug cock and gear-box is linked up.
In the utility model: be provided with inside and outside two corral weirs on the described flange, be provided with three supporting rib stiffeners between the inside and outside cofferdam at least; Described oil sealing and bearing are arranged in the inner ring cofferdam, fixedly connected with the casing of input end by bolt in the cofferdam, outer ring; Described oil duct is located in the supporting rib stiffener, and described a pair of lubricated plug cock is located on cofferdam, the outer ring wall of flange.
In the utility model: described a pair of lubricated plug cock is located on cofferdam, the outer ring wall of the zones of different that forms after supported stiffening rib is cut apart.
In the utility model: described oil sealing is two skeleton single procheilon structures arranged side by side.
In the utility model: the front end and back end of described oil sealing is equipped with circlip for hole; Described bearing also is furnished with circlip for shaft by being located at the shaft shoulder location on input shaft and the flange on the input shaft, also be furnished with circlip for hole in the flange, and described axle lays respectively at the bearing both sides with elasticity retaining and described circlip for hole.
In the utility model: described wind-driven generator wheel-box is meant driftage or variable propeller gearbox, and the input end of described input shaft is provided with internal spline.
Advantage of the present utility model is: because input end adopts lubricant grease that bearing is lubricated simultaneously, under the prerequisite that reduces the gear box lubricating oil adding amount, also can guarantee the lubrication effect of bearing, reduce operating cost; Because the iron filings and the impurity that have adopted the deep groove ball bearing that has monolateral sealing can stop effectively that gear engagement produces enter bearing and oil sealing, have prolonged the working life of gear-box; Because flange adopts inside and outside two corral weirs, at least be provided with three supporting rib stiffeners between the inside and outside cofferdam, oil sealing and bearing are placed the inner ring cofferdam, fixedly connected with the casing of input end by bolt in the cofferdam, outer ring, compact structure not only, stressed reasonable, and it is long-pending with the relative contact of axle to have prolonged flange, makes the input shaft operation more steady.
