Wind power gear machining: high efficiency and stability, CBN cutter advantage highlights

2024-09-27

Wind power refers to the conversion of the kinetic energy of the wind into electrical energy. Wind energy is a clean and harmless renewable energy source, and the use of wind power is very environmentally friendly and has a huge amount of wind energy, so it is increasingly being valued by countries around the world.

 

As the core of the wind power generation system, the wind turbine is to transfer the rotational speed obtained from the wind turbine, through the transmission device, that is, the gear box speed up to the power generation mechanism to run, so as to transform the mechanical energy into electrical energy. Wind power gearboxes have a wide range of applications, not only limited to the field of wind power generation, but also widely used in conveying equipment, chemical equipment, environmental protection machinery and other fields.

 

Wind power gearboxes have the advantages of large load carrying capacity and low noise, but the disadvantages are complex structure, high processing and assembly requirements. The design and manufacture of wind power gearboxes also need to take into account the special environmental conditions and load characteristics of wind power generation to ensure the reliability and durability of the gearbox. Therefore, the machining accuracy of gears is required to be high.

 

Wind power gear turning process has the following processing difficulties: high roughness requirements, poor workpiece clamping rigidity, easy to produce vibration pattern during processing, which adopts a unique edge design to achieve efficient and stable processing.
