Description
Technical field
The utility model relates to the step-up gear in a kind of wind-power electricity generation, belong to a kind of gear transmission transmission device.
Technical background
Along with the rapid increase of the whole world to the wind-power electricity generation demand, this life circle, the growth of blowout formula appearred in scope wind-powered electricity generation industry, and quick growth has also appearred in China's wind-power electricity generation industry.At present, the world wide wind power generating set mainly contains three kinds of forms: first kind is directly directly to drive main shaft by wind power blade to rotate, and is directly driven the form of directly driving of generator for electricity generation by main shaft; Second kind is to drive main shaft by blade, and main shaft driven gear case is brought up to high rotating speed by gear-box with rotating speed, drives the common form of high-speed engine generating; The third is that blade drives main shaft, and main shaft driven gear case is brought up to middle and slow speed of revolution by gear-box with rotating speed, the combination drive form of low-speed generator generating in the drive.To first kind of form, because the power requirements of wind-power electricity generation is increasing now, just make that the size of directly driving generator is increasing, because domestic present technology is defectiveness also, present high-power direct wind-driven generator all becomes extremely difficult even unfeasible from producing, assemble, be transported to on-the-spot the installation; Second kind of form is the main type of service of present wind-power electricity generation industry, but the speed ratio of its gear-box is very big, the rotating speed of gear-box output is very high, add the particularity that wind-power electricity generation industry gear-box uses, uncertainty to the variation of wind field wind-force, the rate of fault very high (all appearing on the high speed shaft-output shaft of gear-box more than 70% in the fault of gear-box wherein) of the gear-box that makes, lowered the reliability of wind power generating set greatly, have a strong impact on the operation of wind power generating set, increase the operation cost of wind-power electricity generation, restricted the development of wind-power electricity generation industry; Because all there is major defect in preceding dual mode, in order effectively to solve the problem that exists now, the third combination drive form is suggested, and become the main developing direction of present world wind-power electricity generation gradually, along with the fast development of wind-powered electricity generation industry, combination drive will welcome the peak of a fast development.
Summary of the invention
The purpose of this utility model is the deficiency that prior art exists, and a kind of stability and reliability that can improve whole drive system is provided, and reduces the wind-power electricity generation operation cost, and compact structure, and running is steady, the semi-direct driving wind power generating speedup box that transmission efficiency is high.
The concrete scheme that the utility model adopts is as follows: it comprises a locking plate that is connected with the macro-axis that is driven by fan blade, quill shaft planet carrier in this locking plate and the casing is connected, on the planet axis on the planet carrier planet wheel is arranged, this planet wheel meshes respectively with the ring gear and the sun gear that are connected on preceding casing and the rear box, sun gear is connected by spline and quill shaft, be fixed with the output gearwheel on the quill shaft, this output gearwheel links to each other with band tooth output shaft.
Described sun gear adopts torsion shaft mechanism, can be offset under the effect of torsion, effectively solves planetary pinion and all carries; Casing adopts overall structure before described, and it can improve the strength and stiffness of gear-box, improves the accuracy of mesh of gear-box; And ring gear is placed between preceding casing and the rear box.
The utility model is made of the two-stage transmission, compact structure, transmission efficiency height; Because the gear-box output speed is low, reduce the mesh impact and the high-frequency vibration of gear-box, because preceding casing is whole casing, improve the strength and stiffness of gear-box greatly the working life that can significantly improve gear and bearing, help guaranteeing the accuracy of mesh of gear-box.These measures will make working life, stability and the reliability of gear-box strengthen greatly, thereby reduce the operation cost of wind-power electricity generation greatly, for wind-power electricity generation brings reliable transmission system.
