Gear Big Block Forging Sun Gear And Planet Gear Made In China

Gear Big Block Gear Forging Sun Gear And Planet Gear Made In China

In shaft drive gearboxes, the sun gear drives the surrounding planetary gears which are housed in a rotating carrier. The ring gear is held stationary with the rotating carrier delivering drive to the shaft. The housing of the gearbox is fixed directly to the machine with the output being a rotating shaft.

Wind turbine forging Specification

Wind turbine forging procedure

Orging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment

High-precision dimensional tolerance;Excellent mechanical properties;Produce different dimension based on customer’s requirements;Advanced manufacture equipments and inspection devices;Excellent technical personality;Control the production procedure strictly;Pay attention on the package protection;Quality full service.
