Description
Technical field
The utility model relates to the technical field that wind-driven generator group wheel box all carries, and refers in particular to a kind of sun gear floating structure of compact type wind-driven generator group wheel box.
Background technique
Known in the industry, in wind-driven generator group wheel box, general employing sun gear floats and improves the stand under load of planet wheel, in order to make planet wheel effect of load balancing mechanism better, need the amount of floating increasing sun gear, traditional wind group gear-box is by increasing the length of sun gear output shaft along power transimission direction (generator side), but this mode adds the length of Transmitted chains.This patent product increases sun gear output shaft along power opposite direction (hub side) length to strengthen sun gear amount of floating, do not increase the length of Transmitted chains, be applicable in compact type wind power generating set.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of sun gear floating structure of compact type wind-driven generator group wheel box is provided, the length not increasing Transmitted chains effectively improves the amount of floating of sun gear, and structure is compacter, and effect of load balancing mechanism is better.
For achieving the above object, technological scheme provided by the utility model is: a kind of sun gear floating structure of compact type wind-driven generator group wheel box, includes spline housing, sun gear, sun gear output shaft, wherein, the endoporus of described spline housing is step hole, and is formed with two circles internal tooth not of uniform size, realizes splined respectively with sun gear and sun gear output shaft, described sun gear is assemblied in sun gear output shaft, is Spielpassung, the two ends of described sun gear output shaft are all outer stretches out this sun gear, its one end extends towards the generator direction of wind power generating set, and be connected with the secondary planet frame of secondary planetary gear mechanism in gear-box, its the other end extends towards the wheel hub direction of wind power generating set, and multiplely internal tooth groove is one to one enclosed with one of spline housing along spaced apart being provided with of its circumference on this end axle body, realize the splined of spline housing and sun gear output shaft, and one end of this end and sun gear is jointly through the primary planet carrier of primary planet pinion mechanism in gear-box, described primary planet carrier is connected with wheel hub by bolt, described sun gear is provided with multiple another with spline housing and encloses internal tooth groove one to one along its circumference is spaced apart through this end wheel of primary planet carrier with it, realize the splined of spline housing and sun gear, described sun gear is connected transmitted power with sun gear output shaft by spline housing.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
Compare traditional sun gear output shaft and be directly connected to secondary planet frame, can find that sun gear output shaft is larger to the span of secondary planet frame by this sun gear floating structure, sun gear floats larger, all carries better, and do not need the length increasing Transmitted chains, more compact structure.
