Gearbox
Gearboxes have a wide range of applications, such as in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Its main function is to transfer the power generated by the wind wheel under the action of wind to the generator and make it get the corresponding speed.
Generally, the rotation speed of the wind wheel is very low, far less than the rotation speed required by the generator to generate electricity. It must be realized by the speed increasing effect of the gear pair of the gear box, so the gear box is also called the speed increasing box.
1, The bearings of the transmission parts are all selected domestic well-known brand bearings or imported bearings, and the seals are selected skeleton oil seals; the structure of the suction box, the larger surface area of the cabinet and the large fan; reduce the temperature rise and noise of the whole machine, and improve the reliability of operation , The transmission power increases.
2, It can realize parallel shaft, right-angle shaft, vertical and horizontal general box. The input methods include motor connection flange and shaft input; the output shaft can be output at right angles or horizontally. Solid shaft and hollow shaft, flanged output shaft are available . The gearbox can meet the installation requirements of the narrow space, and can also be supplied according to customer needs. Its volume is 1/2 smaller than that of the soft gear reducer, the weight is reduced by half, the service life is increased by 3 to 4 times, and the carrying capacity is increased by 8 to 10 times.
3, Widely used in printing and packaging machinery, three-dimensional garage equipment, environmental protection machinery, conveying equipment, chemical equipment, metallurgical mining equipment, iron and steel power equipment, mixing equipment, road construction machinery, sugar industry, wind power generation, escalator and elevator drives, shipbuilding, light High-power, high-speed ratio, high-torque occasions such as industrial field, papermaking field, metallurgical industry, sewage treatment, building material industry, lifting machinery, conveyor line, assembly line, etc. It has a good cost performance and is conducive to the matching of localized equipment.
