2025 New Model Compact 3-High Corrosion-Resistant Precision Planetary Reducer - 3-Stage Low-Backlash Back-Drivable Right-Angle Type for AC Servo

Product Description

Planetary reducer is a widely used industrial product that can reduce the speed of the motor while increasing the output torque.Planetary reducer can be used as supporting parts for lifting, mining, transportation, construction and other industries.

The planetary gear reducer has the following features: light weight, small size, large transmission ratio range, high efficiency, smooth operation, low noise, and strong adaptability. It is widely used in industrial departments such as metallurgy, mining, hoisting and transportation, power generation, energy, construction and building materials, light industry, and transportation.
Product description:
1. The planetary gear reducer adopts modular design and can be changed and combined according to customer requirements.
2. The reducer uses an epicyclic planetary gear transmission and rationally utilizes internal and external meshing and power distribution.
3. The housing is made of ductile iron, which greatly improves the rigidity and shock resistance of the housing.
4. All gears are carburized and quenched, with a high hardness and wear-resistant surface. After heat treatment, all gears are ground, reducing noise and improving the efficiency and service life of the entire machine.
5. The planetary gear reducer products have 9-34 types, and the planetary transmission gear ratio has 2 and 3 levels.
Speed reduction ratio: 25~4000r/min (combined with RX, R, and K series to achieve a larger speed reduction ratio)
Output torque: up to 2,600,000 Nm
Motor power: 0.4-129,340 kW

 FEATURES:

• High efficiency: The single-stage efficiency can reach over 95%
• High precision: generally less than 10 arc minutes, even up to 5 arc minutes
• Strong bearing capacity: radial load can reach over 20000N
• Compact structure and small volume: usually with an outer diameter size of tens to hundreds of millimeters
• Low noise and minimal vibration: The noise level during operation is usually below 65dB
• Wide speed ratio range: single-stage speed ratios range from 3-10, and multi-stage combinations can reach thousands
• High reliability and long lifespan: the service life can reach 20000 hour

Our Advantages

1. High Precision: back gap is less than 5 arc minutes, accurate positioning.
2. The precision of the gear can be controlled below ISO4 level by using the top ultra-precision machine tool and the world's leading tooth grinding.
3. The gear material is made of advanced low carbon alloy forged steel. After deed heat treatment, it can reach HRC60.
4. It can be adapted to any servo motor in the world.
5. Using synthetic grease, and adopt IP65 sealing design, no leakage and no maintenance.
6. The cage planetary support structure and the output shaft are integrated to achieve high stiffness and precision.
