Grinding 120 Angle Gear Hardened Alloy Steel For Planetary Reducer

Grinding 120 Angle Gear Hardened Alloy Steel for Planetary Reducer

Appearance & Structure
Dimensions: The overall size of the gear is regular, in line with the standard size requirements corresponding to the "120" specification. There is a round hole in the middle, which is easy to install and fix through the shaft, and adapts to the internal structure layout of the planetary redeucer to ensure accurate assembly with other components.
Gear shape: Present the shape of a helical gear with a hard tooth surface. The tooth surface is smooth and glossy, treated with a carburizing-grinding process. The teeth are distributed in a spiral oblique shape, and this helical tooth design can increase the coincidence of gear meshing, which makes the transmission more stable and the bearing capacity stronger than that of the straight teeth, and effectively reduces the impact and noise during the transmission process. At the same time, the characteristics of the hard tooth surface make the gear have high hardness, rigidity, toughness and wear resistance, and can adapt to the long-term and high-intensity working environment of the planetary reducer.
Angular structure: They cooperate with specific components in the planetary reducer, which can realize the power transmission of the input shaft and the output shaft at an angle of 120°, meet the needs of special space layout and transmission direction change, and let the power be reasonably distributed and transmitted in the complex planetary reducer system.

Performance parameters
Reduction ratio: In planetary reducers, such gears can be combined with other components to achieve a wide range of reduction ratios.
Accuracy: From the perspective of the precision tooth shape processing of gears, its accuracy level is high, which ensures the accuracy and stability of transmission, reduces transmission errors, and ensures that the planetary reducer outputs stable and reliable power.

Materials & Manufacturing
Material: The gear material is high-quality alloy steel. After carburizing, quenching and other heat treatments, the surface hardness of this steel is greatly improved, the wear resistance is enhanced, and the internal toughness is still maintained, so that the gear is not easy to wear and fracture when bearing large loads and frequent meshing movements.
Manufacturing process: Using high-precision processing equipment and technology, the gear hobbing process first preliminarily processes the tooth shape, and then finely polishes the tooth surface through the gear grinding process to ensure that the tooth shape is accurate and the tooth surface is smooth, so as to meet the strict requirements of the planetary reducer for the gear transmission performance.
