What is a gear box?

  When the gearbox receives the force from the wind wheel and the reaction force generated during the gear transmission, it must have enough rigidity to bear the force and torque to prevent deformation and ensure the transmission quality. The design of the gearbox housing should be carried out in accordance with the layout and arrangement of the wind turbine power transmission, processing and assembly conditions, and ease of inspection and maintenance. With the rapid development of the gearbox industry, more and more industries and different companies have applied gearboxes, and more and more companies have grown in the gearbox industry. 
  Based on the modular design principle of the unit structure, the gear box greatly reduces the types of components and is suitable for large-scale production and flexible and flexible selection. Reducer spiral bevel gears, helical gears are made of high-quality alloy steel carburizing quenching, tooth surface hardness of up to 60 ± 2HRC, tooth grinding precision up to 5-6. 
  Transmission bearings are selected from domestic well-known brands bearing or imported bearings, seals selected skeleton seal; suction speaker structure, larger box surface area and large fan; the whole temperature rise, noise reduction, operation reliability is improved Increased transmission power. It can realize parallel shaft, orthogonal shaft, vertical and horizontal universal box. The input method includes motor connection flange and shaft input. The output shaft can be output at right angle or horizontal level. Solid shaft and hollow shaft and flanged disk output shaft are available. . The gearbox can meet the installation requirements of a narrow space and can.
