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.
