Abstract
The invention provides a wind-power gearbox capable of reducing an impact force. The wind-power gearbox is that a planet carrier of a first-stage planetary line is coupled with the planet carrier of a second-stage planetary line; a sun gear of the first-stage planetary line is connected with an inner gear ring of the second-stage planetary line; the input torque is input through the planet carrier of the first-stage planetary line and is output through the sun gear of the second-stage planetary line under the transmission effect of the two stages of planetary lines. The wind-power gearbox capable of reducing the impact force has the technical effects that the sun gears, the inner gear rings and the planet carriers of the two stages of planetary wheel lines can bear the input impact force together, so that the impact force can be effectively dispersed and transmitted; the input impact load can be dispersed and transmitted through the wind-power gearbox, and therefore, the influence of the impact force on a gear case can be decreased, the vibration of the wind-power gearbox can be effectively reduced, and as a result, the gear-power gearbox can reliably and stably run in a terrible environment.
Description

The present invention relates to a kind of wind power speed-increasing gearbox, particularly relate to a kind of wind power speed-increasing gearbox of the reduced impact force be mainly used in great wind-power units.
Background technique
Owing to having compact structure, the advantage such as volume is little, transmission efficiency is high and velocity ratio is large, Planetary Gear Transmission is applied in the fields such as wind-driven generator transmission system, aviation power transmission system, vehicle drive system widely.Wind energy is cleanliness without any pollution and one of renewable important energy source in the world, along with going from bad to worse of energy shortage and ecotope, it is widely acknowledged the significance of generation of electricity by new energy technology.Gear-box is one of critical component of wind power plant, and its load of bearing is very complicated, is mainly used in step-up drive.Gear-box is one of parts that wind power generating set rate of fault is the highest, in order to reduce the rate of fault of gear-box, improves its operating life and reliability, is necessary to further investigate the impact resistance of Planetary Gear Transmission.
The development of wind-powered electricity generation equipment technology is very rapid, as variable speed constant frequency technology, variable-pitch variable-speed, full power Semiconductor Converting Technology, directly drives and semi-direct driving wind group of motors.Direct drive wind power unit adopts multipolar dynamo to be directly connected with impeller the mode carrying out driving, and removes gear-box from, and share of installing in recent years constantly increases.But due to the aspect such as technology and cost, the Wind turbines with step-up gear within the following long period will be occupied an leading position in the market.Because planetary gear train has multiple planetary pinion, dirivig member is many, and motion conditions is complicated, and the work under bad environment of wind power speed-increasing gearbox in addition, the impact force of huge input will badly influence service behaviour and the working life of wind power speed-increasing gearbox.
Summary of the invention
The object of the present invention is to provide a kind of wind power speed-increasing gearbox reducing impact force, solve dirivig member in prior art many, motion conditions is complicated, the work under bad environment of wind power speed-increasing gearbox, the impact force of huge input is by the problem of the service behaviour and working life that badly influence wind power speed-increasing gearbox.
The present invention realizes like this, it comprises the sun gear of first order planet row, the planet carrier of first order planet row, the planetary pinion of first order planet row, the ring gear of first order planet row, the ring gear of second level planet row, the sun gear of second level planet row and the planet carrier of second level planet row, the ring gear of first order planet row is connected with a joggle the planetary pinion of first order planet row, the planetary pinion of first order planet row connects the planet carrier of first order planet row, it is characterized in that: the planet carrier of first order planet row is coupled mutually with the planet carrier of second level planet row, the sun gear of first order planet row is connected with the ring gear of second level planet row, input torque is inputted by the planet carrier of first order planet row, transmission through two-stage planet row is exported by the sun gear of second level planet schedule.
Technique effect of the present invention is: adopt the present invention that the sun gear of two-stage planet schedule, ring gear and planet carrier can be made to bear the impact force of input simultaneously, and the dispersion path that effectively can realize impact force is transmitted; The dispersion path that wind power speed-increasing gearbox can realize inputting impulsive load is transmitted, and can reduce the impact of impact force on gear-box dynamic performance, effectively can weaken the vibration of wind power speed-increasing gearbox, be conducive to wind power speed-increasing gearbox reliable and stable operation in the presence of a harsh environment.
