Summary of the invention
The objective of the invention is to: at step-up gear, especially wheel hub is many to the transmission progression of generator, and the practical problem that the speed-increasing gearbox of wind driven generator rate of fault is higher provides a kind of new hybrid driving type wind motor increasing gear case.
The object of the present invention is achieved like this: a kind of hybrid driving type wind motor increasing gear case, and casing, input planet carrier, sun gear, planet wheel, output spline before and after comprising is characterized in that:
A) ring gear is located between the forward and backward casing, and they connect by bolt successively, are furnished with rear end cover on the rear box;
B) input planet carrier and the sun gear concentric that directly docks with wheel hub, on the casing of front and back, its input end passes preceding casing by Bearing Installation in the front end and back end of input planet carrier; Input planet carrier periphery evenly is provided with three planet wheels, and planet wheel meshes with ring gear, sun gear simultaneously; One end of sun wheel shaft combines with the input planet carrier by bearing, the sun wheel shaft end is provided with lid, the other end end of sun wheel shaft is connected with output spline by spline, and output spline is provided with bearing with input junction, planet carrier rear end, and output spline passes through rear box;
C) input planet carrier front end and preceding casing junction, import in the saturating lid of planet carrier and sun wheel shaft junction and output spline and rear box junction are equipped with seal arrangement;
B) be equipped with oil leab before and after in casing and the input planet carrier towards bearing.
In the present invention: on rear box, rear box is provided with baffle ring by Bearing Installation in the rear end of input planet carrier, is furnished with tin bronze bush between baffle ring and the input planet carrier.
In the present invention: described bearing is a cylindrical roller bearing, or full roller bearing, or double-row conical bearing, or four-point contact ball.
In the present invention: the bearing of input planet carrier and rear box junction adopts full roller bearing, sun wheel shaft adopts four spot contact bearings with the bearing of input planet carrier junction, planet wheel is installed on the planet wheel shaft by cylindrical roller bearing or full roller bearing, and output spline adopts cylindrical roller bearing or full roller bearing with the bearing of input planet carrier junction.
The invention has the advantages that: owing in the wind-driven generator, directly be delivered to the input planet carrier of gear-box from wheel hub, and adopt one-level planetary gear train speedup, reduced the transmission progression of wheel hub to generator, will reduce the total breakdown rate of wind-driven generator greatly; Because input planet carrier front end is installed on the preceding casing by a double-row conical bearing, the input planet carrier the rear end by Bearing Installation on rear box, the mounting type of casing before its input end passes, to omit wheel hub in the use to the input shaft between the gear-box, it is compact more to make wheel hub arrive generator Structure; Be equipped with oil leab in front and back casing and the input planet carrier, can provide pressure lubrication by mechanical pump to gear engagement place and all bearings by a sealed reservoir in the use, improved the reliability of gear-box work towards bearing.
