The copper ring of the wind turbine gearbox is an important mechanical component in wind turbines. Its main function is to transfer the power generated by the wind turbine under the action of the wind to the generator and obtain the corresponding speed. Due to the installation of the unit in wind vents such as high mountains, wilderness, beaches, and islands, the working environment is harsh, and the natural environment is inconvenient for transportation. Once a malfunction occurs, it is difficult to repair. Therefore, the reliability and service life of its various accessories, including oil seals and floating oil distribution rings, are much higher than those of ordinary machinery. Our company's products have the characteristics of high reliability, high load-bearing capacity, and high cost-effectiveness. The floating oil distribution ring, oil seal, and copper ring produced by the company are applied to wind power gearboxes such as 1.5MW, 1.65MW, 2MW, 2.5MW, 2.75MW, 3MW, 3.5MW, 4MW, 5MW, 6WM, and 7WM.

The main material of the copper rings produced by our factory is tin bronze 10-1 (ZCuSn10P1), which has high hardness, excellent wear resistance, is not prone to biting, has good casting and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. ZCuSn10P1 cast copper alloy can be used for wear-resistant parts working under high loads (below 20MPa) and high sliding speeds (8m/s), such as connecting rods, bushings, bearings, gears, worm gears, etc. 02 Tin Bronze 10-1 Composition Analysis Copper Cu: Other Tin Sn: 9.0~11.5 Zinc Zn: ≤ 0.05 (Impurity) Lead Pb: ≤ 0.25 (Impurity) Phosphorus P: 0.8~1.1 Nickel Ni: ≤ 0.10 (Impurity) Aluminum Al: ≤ 0.01 (Impurity) Iron Fe: ≤ 0.1 (Impurity) ZCuSn10Pb1 Cast Tin Bronze Manganese Mn: ≤ 0.05 (Impurity) Silicon Si: ≤ 0.02 (Impurity) Antimony Sb: ≤ 0.05 (Impurity) Sulfur S: ≤ 0.05 (Impurity) Note: Total Impurity ≤ 0.7503 Tin Bronze 10-1 Mechanical Properties Tensile Strength σ B (MPa): ≥ 360 yield strength σ  (MPa): ≥ 170 (reference value) Elongation rate δ 5 (%): ≥ 6 Hardness: ≥ 885HB * or approximately 90HB.
