Abstract
A wind power generating yaw reduction gearbox is used for yawing and reduction of a wind power generating device. The wind power generating yaw reduction gearbox mainly consists of an input shaft, an output shaft, all levels of machine bodies and all levels of planetary gear driving mechanisms. Frame oil seals are not used at the end of the input shaft to seal, so that the input end structure is much compacter; double frame oil seals are adopted in a lower machine body to separate a thin oil area from a glycerine area, so that the frame oil seals can be fully lubricated; an O-shaped sealing ring is used to seal between each machine body and an inner gear ring; and the deviation between the axis of the output shaft and the axis determined by the mounting rabbets and mounting bolts of the gear box is 2 mm, so that the center distance between a pinion and a large yawing gear ring can be adjusted to adjust the meshing relationship by rotating the angle of the gearbox. Compared with the prior yaw reduction gearbox, the gearbox has the advantages that the oil seals are not used at the input end; with an eccentric structure, the gear box is compacter in structure and lighter in weight, and can adjust the meshing relationship at any time; and the frame oil seals are arranged more reasonably.
Description
Technical field
The utility model relates to a kind of uni-drive gear box, relates in particular to the driftage reduction gear box that is used on the wind power plant.
Background technique
Wind-driven generator utilizes natural wind to drive generator work, because the wind-force direction changes unpredictably, and have many-sided uncertain factors such as impact force, so must the configuration high-performance in the wind-driven generator, at a high speed than, the stable driftage reduction gear box of running, to regulate and control the angle of wind-driven generator and wind direction.
The reduction gear of used for wind power generation driftage at present both at home and abroad box structure is various, but mainly is two kinds of multi-stage planetary gear gearing down and multistage cycloidal-pin wheel gearing down.Because cycloidal-pin wheel gearing down anti-impact force is relatively poor, so adopt the multi-stage planetary gear reducing transmission structure usually.
Traditional driftage reduction gear box all is equipped with oil sealing at input/output terminal, and gear-box does not adopt eccentric structure, can't mesh adjustment.
Summary of the invention
Can't mesh the shortcoming of adjustment for overcoming tradition driftage reduction gear box, this use is novel to provide a kind of gear-box with eccentric structure, this gear-box is a Pyatyi planetary pinion drive mechanism, constitute by input shaft, output shaft, body at different levels, planetary gear mechanism at different levels, input shaft is installed in the input flange by first order bearings, do not adopt sealed member, input shaft is connected by spline with first order sun gear, and with planet carriers at different levels, sun gear at different levels and output shaft concentric; First order planet carrier is connected with second level sun gear by spline, second level planet carrier is connected with third level sun gear by spline, third level planet carrier is connected with fourth stage sun gear by spline, fourth stage planet carrier is connected with the level V sun gear by spline, and the level V planet carrier is connected with output shaft by spline; First and second grade ring gear puts together between input flange and the first order body by bolt, third level ring gear puts together between first order body and the second level body by bolt, fourth stage ring gear puts together between second level body and the third level body by bolt, and the level V ring gear puts together between third level body and the lower body by bolt; Every grade of planetary pinion cooperates with planet wheel shaft by needle bearing and is installed on the planet carrier; In lower body, adopt two outside framework oil seal forms to come every minute thin oil and glycerine district; Be injection glycerine district between two outside framework oil seals; Lower body adopts skeleton oil seal closing on the end cap; Between each body and ring gear, adopt the sealing of O RunddichtringO; Deviation 2mm between the axis that the installation seam of the axis of output shaft and gear-box and construction bolt are determined.
The beneficial effects of the utility model are, compare with traditional driftage reduction gear box, do not have oil sealing at input end, and gear-box adopts eccentric structure, make its compact structure, and can mesh adjustment at any time, and it is more reasonable that outside framework oil seal is arranged.
