The gearbox is widely used in wind turbines and is an important mechanical component. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and obtain the corresponding speed. Usually, the speed of the wind turbine is very low, far from reaching the required speed for generator power generation. It needs to be achieved through the increasing speed effect of the gearbox gear pair, so the gearbox is also called the increasing speed box.

The gearbox bears the force from the wind wheel and the reaction force generated during gear transmission, and needs to have sufficient rigidity to withstand the force and torque, prevent deformation, and ensure transmission quality. The design of the gearbox box should be carried out in accordance with the layout arrangement, processing and assembly conditions, and convenience for inspection and maintenance of the wind turbine power transmission. With the continuous and rapid development of the gearbox industry, more and more industries and different enterprises have applied gearboxes, and more and more enterprises are developing and growing in the gearbox industry.

The company's main products include: automotive parts, diesel engine parts, engineering machinery parts, air compressor parts, die-casting machine consumables, and brake systems. It is a casting manufacturer that provides high-quality spare parts for the mechanical manufacturing industry.
