product description

The gearbox in wind turbines is an important mechanical component

High technical requirements (large diameter, easy to deform, difficult to grind teeth such as internal gear rings, irregular gears such as those that cannot be induction quenched, etc.)

High performance requirements (high surface hardness, high residual compressive stress on the surface, and need to control the depth of the tooth root layer)

The performance requirements for the heart are relatively low, and it is necessary to reduce costs and shorten production cycles (relative to carburizing+gear grinding)

Traditional craftsmanship is limited by the furnace and cannot harden oversized gears (gears 2-6 meters or more)

Uneven hardness of traditional flame and other surface quenching processes
