1. Integrated molding of complex irregular structures to reduce welding joints.
Complex large components with multiple flanges, reinforcing ribs, multiple installation bosses, and multiple bearing installation positions can be cast in one go.
Merge multiple parts into a single casting, significantly reducing the number of welds and avoiding the risk of fatigue cracking and residual stress in welded joints;
Wall thickness and fillet can be optimized through simulation, stress distribution can be optimized, stress concentration under alternating loads can be reduced, and wind turbines can be adapted to continuously fluctuating wind loads.
2. Cast steel material is fatigue resistant and low temperature resistant, suitable for onshore/offshore wind power.
Selecting alloy cast steel with excellent low-temperature impact toughness and high fatigue strength, suitable for low-temperature and offshore salt spray corrosion conditions in the north; Adjustable alloy composition enhances resistance to chloride ion corrosion and meets the long-term requirements of offshore wind power. The start stop of the fan and the impact of gusts bring alternating torque, and the overall toughness of the cast steel parts is good, making it less prone to brittle fracture and ensuring the design life.
3. Strong ability to form large parts and high degree of structural design freedom.
It is difficult to forge complex multi branch structures for large volume, multi-directional force bearing shaped parts such as wind turbine hubs and planetary carriers. Casting can achieve large blank forming, and the structure is not limited by forging technology; Local thickening and reinforcement can be made according to the force, achieving lightweight design while ensuring stiffness.
4. Compared to welded structural components, it has higher long-term reliability.
There are a large number of welded joints and residual stresses in the steel plate welding frame, and the weld seam is prone to fatigue cracks under long-term alternating vibration;
Cast steel integrated molding, with very few joints, better vibration fatigue performance, and reduced risk of high-altitude fan failure.
The value brought by mechanical processing (cast steel blanks cannot be directly installed)
1. Ensure the accuracy of bearing holes, flanges, and bolt holes, and control the transmission clearance.
Perform CNC boring and milling machining on bearing seat holes, planetary carrier shaft holes, flange joint surfaces, and bolt installation benchmarks, strictly controlling coaxiality, roundness, flatness, and roughness. Ensure the assembly clearance of bearings and gears, reduce vibration and noise, avoid early wear of the gearbox, and ensure stable operation of the transmission system.
2. Correct casting deformation and unify assembly standards.
Cooling large castings can cause warping deformation. By using large gantry CNC machining to calibrate the benchmark, the assembly tolerance of the entire machine can be ensured.
3. Remove surface defects from castings to improve fatigue performance.
Machining removes sand, oxide scale, and small pores on the surface of castings, exposing a dense metal matrix, eliminating surface crack sources, and significantly improving the fatigue resistance of components.
4. Adapt to subsequent anti-corrosion and surface strengthening processes.
A uniform and flat machined surface is conducive to sandblasting, primer, and heavy-duty anti-corrosion coating construction.
