Structural features: Integrated design of planetary carrier and output shaft (maximizing torsional stiffness); The planetary gear adopts a fully needle roller design (increasing contact area, improving structural stiffness and output torque); The gears are treated with low-carbon steel carburizing and quenching (hardness HRC62, ensuring wear resistance and impact toughness); Double side clamping connection between input shaft and motor shaft (achieving zero backlash power transmission)

Transmission efficiency: up to 95% (97% -98% under optimal operating conditions)


Product advantages

High precision and low backlash: The minimum backlash is ≤ 1 arcminute, ensuring precise transmission and stable operation of precision equipment.

High efficiency and high torque: The transmission efficiency is as high as 95% -98%, and the integrated structural design and full needle roller planetary wheel design enhance the output torque and load-bearing capacity.

Durable and maintenance free: High quality gear material (HRC62 quenched steel) combined with precision manufacturing technology extends its service life, ensures long-term reliable operation, and has low maintenance costs.

Low noise and low vibration: Using imported software to optimize gear tooth profile, combined with sturdy structural design, significantly reduces operating noise and vibration.

Strong adaptability: With a wide range of models, transmission ratios, and load ranges, it can adapt to different working conditions and installation space requirements.
