The planetary gearbox is also called a mini planetary gearbox. Its structure is a mechanism in which multiple planetary gears rotate around a sun gear. It is also a mechanism that reduces the transmission speed ratio and increases the motor torque proportionally. The precision planetary gearbox is made of high-performance alloy steel with special heat treatment, and the flange is made of aluminum alloy. It has the characteristics of beautiful appearance, small size, light weight, large torque, low noise, high efficiency, and long service life. It can be equipped with power sources such as DC motors, single-phase motors, synchronous motors and various three-phase asynchronous motors. Fully enclosed with high-performance grease, maintenance-free for life.

Precision planetary gearbox performance characteristics

1. The backlash gap is small and the transmission accuracy is high.

2. High cost performance, the lowest price under the same accuracy conditions.

3. Low noise, <60 decibels; long life, >20,000 hours.

4. The transmission torque is large, the meshing adopts multi-tooth meshing, and the rated output torque is high.

5. Compact structure and small size, it is the smallest among existing reducers of the same type.

6. The sealing design is good, all are lubricated with grease, no leakage, and maintenance-free.

7. Speed ratio range: speed ratio 5 to 10,000, enabling application design to achieve the best matching of torque and speed.

8. High rigidity, the gear adopts alloy steel nitrided hard tooth surface, which has excellent wear resistance and impact resistance.

9. Easy installation, coaxial output, standard flange positioning, suitable for motors of any manufacturer and form.

10. High transmission efficiency (>=90%), large transmission power, high radial load capacity, and single-stage series transmission.

11. The high-pressure die-cast aluminum alloy casing adopts new processing technology to improve the accuracy of the workpiece. It has been anodized to enhance environmental tolerance and corrosion resistance, reduce weight, enhance thermal conductivity, reduce internal temperature rise, and reduce heat generation.

Transmission characteristics of mini planetary gearbox

The main transmission characteristics of planetary gearboxes are: small size, high quality, compact structure, large load-bearing capacity, large transmission ratio, high transmission efficiency, smooth transmission, and strong resistance to shock and vibration. Generally speaking, under the same load conditions, the outer size and mass of the planetary gear transmission are about 1/2-1/5 of the ordinary gear transmission. Due to the symmetry of the planetary gear transmission structure, the impact on the center wheel and The reaction forces in the swing arm bearings can balance each other, which is beneficial to improving transmission efficiency.

Among the failures of mini planetary gearbox, 40% are caused by factors such as design, manufacturing, assembly and raw materials, and 43% are caused by untimely maintenance and improper operation by users. The rest are caused by faults or defects in adjacent conditions. In order to ensure the safe and normal operation of wind power gearboxes and improve the reliability of gear transmission, on the one hand, it is necessary to improve the design, improve the processing and manufacturing accuracy, and improve the assembly quality. On the other hand, the level of operation management and maintenance must be improved. Perform condition monitoring and fault diagnosis on gear transmissions.
