LGY SINGLE-STAGE PRECISION: p 2≤7 AM DOUBLE-STAGE PRECISION: p 2≤9 am noise: ≤63 db Ring Gear: Adopt one-piece structure, gear box and inner ring gear body forging, through imported tooth shape software and ANSYS to design better tooth shape, after tooth shape grinding, the accuracy of the ring gear is less than 2 m, and the module of the planetary gear is bigger. After optimizing the Helix Angle, the accuracy is better and the accuracy life is increased by 35% . After vacuum carburizing and heat treatment to the best hardness, the planetary gear has both surface hardness and core toughness. The radial structure is more compact by using imported full needle roller bearing with small clearance tolerance. Planetary Support: the output shaft for the imported cylindrical grinder for smooth surface treatment RA0.2 m, with the oil seal to ensure a lower coefficient of friction, reduce the starting torque and ensure a better sealing of the output shaft root heat treatment to the best hardnes
