Product Introduction:
Planetary gears are a crucial component of the planetary gear mechanism in wind turbine speed-increasing gearboxes. Their manufacturing process is relatively complex and typically includes processes such as steelmaking, forging, post-forging normalizing and tempering, rough machining, carburizing and quenching, and finishing. Each process has strict requirements for processing accuracy and quality to ensure the dimensional accuracy, tooth profile accuracy, and surface quality of the planetary gears, thereby guaranteeing their reliable operation under high-speed and heavy-load conditions.
Product Advantages:
Planetary gear as a key component of the planetary gear train, the design and manufacturing advantages directly affect the transmission efficiency, reliability, and service life of speed-increasing gearboxes. With multiple teeth collaboratively bearing loads, they feature high space utilization, achieving a balance between lightweight and high strength. Their profile modification technology improves meshing accuracy, ensuring smooth transmission with low vibration and noise. The tooth surfaces undergo intensive shot peening treatment to form a compressive stress layer, thereby extending fatigue resistance and service life.
Production Process:
Raw material inspection → Cutting → Forging → Normalizing → Rough turning → UT → Half-finished turning → Gear milling → Carburizing and quenching → Sandblasting → Gear grinding → MT → CMM/GMM → Cleaning packaging
Packaging And Shipping:
Before shipment, the products will go through a process that includes cleaning, labeling, rust-proofing, appearance inspection, and finally packing and warehousing.
Company Strength:
The company is equipped with advanced inspection and testing devices such as imported spectrometers, nitrogen-hydrogen-oxygen analyzers, Zeiss metallographic microscopes, Zeiss CMMs, and M2M ultrasonic phased array flaw detectors. It has the comprehensive capability to conduct inspections from raw material composition, performance, dimensions, form and position tolerances to non-destructive testing.
