Embodiment Construction
[0009] Such as figure 1 As shown, the present invention is realized in such a way that the ring gear 4 of the first-stage planetary row meshes with the planetary gear 3 of the first-stage planetary row, and the planetary gear 3 of the first-stage planetary row is connected with the planet carrier of the first-stage planetary row 2. The planetary carrier 2 of the first-stage planetary row is coupled with the planetary carrier 8 of the second-stage planetary row, the sun gear 1 of the first-stage planetary row is connected with the ring gear 5 of the second-stage planetary row, and the input torque It is input by the planetary carrier 2 of the first-stage planetary row, and the transmission of the two-stage planetary row is output by the sun gear 7 of the second-stage planetary row. The ring gear 4 of the first-stage planetary row is fixed, and the sun gear 1 of the first-stage planetary row is used as an output; the second-stage planetary row is a differential planetary gear tr...

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
technical field [0001] The invention relates to a wind power speed-up box, in particular to a wind power speed-up box which can reduce impact force and is mainly used in large-scale wind power generation equipment. Background technique [0002] Due to the advantages of compact structure, small size, high transmission efficiency and large transmission ratio, planetary gear transmission is widely used in wind turbine transmission system, aviation power transmission system, vehicle transmission system and other fields. Wind energy is one of the clean, non-polluting and renewable important energy sources in the world. With the energy shortage and the deteriorating ecological environment, people generally realize the importance of new energy power generation technology. The gearbox is one of the key components of wind power generation equipment, and it bears very complicated loads, and it is mainly used for speed-up transmission. The gearbox is one of the components with the hig...
