What Are The Benefits Of Planetary Gears ?

Planetary gear transmission has the following advantages:

 

1.Compact structure, small size, and lightweight: Planetary gear transmission features planetary motion and power splitting characteristics, enabling full utilization of the large load-bearing capacity of internal meshing and the entire available space of the internal gear ring. This results in advantages such as a compact structure, small external dimensions, and lightweight. Under typical conditions, when transmitting the same power and gear ratio, the volume and weight of a planetary gear reducer motor are approximately 1/2 to 1/6 of those of a conventional gear transmission.

2.With a high transmission ratio, it enables the synthesis and decomposition of motion. There are various types of planetary transmissions, such as involute planetary transmission, cycloidal planetary transmission, harmonic planetary transmission, and ratchet planetary transmission, all generally characterized by a high transmission ratio. When used for transmitting motion, the maximum transmission ratio can reach tens of thousands or even hundreds of thousands. As a power transmission system, the maximum transmission ratio can reach dozens or hundreds. Planetary transmissions with differential motors can achieve the synthesis of two motions and the decomposition of a single action. In certain cases, selecting the appropriate type of planetary gear reducer motor can enable complex motions with various speed variations .

 

3.High efficiency and low power loss: Planetary transmission uses several planetary gears evenly distributed between the inner and outer center wheels, which can balance the inertial forces acting on the center wheel and planetary carrier bearings. Adopting this symmetrical structure is conducive to improving the efficiency of the transmission system. By selecting the appropriate transmission type and designing a reasonable structure, the efficiency of the planetary gear reduction motor can reach 0.97-0.992.

 

4.Transmission balance and strong resistance to impact and vibration: Multiple planetary gears are evenly distributed between two central gears, and a load sharing device is used to maintain uniform load distribution and power distribution between each planetary gear. This not only balances the inertial forces of each planetary gear and the rotating arm, but also significantly improves the stability and resistance to impact and vibration of the planetary gear reduction motor .

 

5.High transmission rate: The pure gear transmission efficiency is as high as 96%, with a larger input power of 200kW and a larger torque of 50000N. m, and a transmission ratio of 5.36-145261.

 

6.Strong bearing capacity: The shell is thick and made of high-quality QT250 cast iron box, and the gear surface has undergone carburizing treatment.

 

7.Wide practicality: It can be made into horizontal, vertical, hollow shaft, flange connection, and can meet various installation needs.

 

8.Smooth operation, low noise, and multiple teeth: Planetary gear reducers have the characteristics and advantages of smooth operation, low noise, and multiple teeth.

 

9.Reduce speed while increasing output torque: The planetary gear reducer will increase its output torque while reducing speed, and the torque output ratio is calculated by multiplying the motor output by the reduction ratio.

 

10.Reduce load inertia while slowing down: The planetary gear reducer also reduces its load inertia while slowing down, and the reduction in inertia is the square of the reduction ratio.

 

11.Smooth transmission, capable of withstanding large loads: Planetary gear transmission is smooth and capable of withstanding large loads.

 

12.Can convert a single unidirectional input into simultaneous, coaxial bidirectional output: planetary gears can convert a single unidirectional input into simultaneous, coaxial bidirectional output
