Overview of TEG120 Series High Precision Planetary Gearbox Helical Gear Reducer

TEG120 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that has a high level of precision. It is designed to provide high efficiency, low backlash, and high torque density. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. The gearbox is used in various applications where high precision and high torque are required.

Basic Structure of High Precision Planetary Gearbox

The High Precision Planetary Gearbox has the following components:

• Sun Gear: Located at the center of the planetary gearbox, it is usually connected to the input shaft or fixed on the housing as a stationary part.
• Planet Gears: Revolve around the sun gear and are supported by the planet carrier to maintain their relative position. Each planet gear meshes with both the sun gear and the ring gear/annulus, and they share and distribute the load when power is input.
• Planet Carrier: A structure with multiple planet gear shaft holes, it carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can be used as an output element or connected to another shaft to transmit or receive torque.
• Ring Gear/Annulus: A large diameter ring gear fixed inside the housing, it has teeth on both its inner and outer surfaces and meshes with the planet gears. In some applications, the ring gear can also serve as an input or output end.
• Bearings and Shaft System: The bearings in the high-precision planetary gearbox support the input shaft, output shaft and planet carrier, ensuring stable rotation and smooth operation between the components.
• Housing: The housing is a sturdy structure that encloses all internal components, providing stable support for the gears. It also protects the internal components from external impurities and may include cooling or lubrication systems.
• Shafts and Keys: The input and output shafts are connected to the sun gear or planet carrier through keys to transfer power and ensure precise torque transmission and axial positioning.
• Seals: Seals are used to prevent lubricating oil leakage and contamination from entering the gearbox, ensuring a clean and good lubrication state inside the gearbox.

Working Principle of High Precision Planetary Gearbox

The working principle of High Precision Planetary Gearbox can be summarized as follows:

1. Torque Transmission and Amplification: When power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate, and the planet gears mesh with both the sun gear and the ring gear/annulus to begin rotation and revolution. Due to the action of multiple sets of planet gears, the load of the entire system is evenly distributed, which can significantly increase the torque of the output end and achieve torque amplification.
2. Speed and Gear Ratio Control: By adjusting the tooth number ratio of the sun gear, planet gears, and ring gear/annulus, the speed relationship and gear ratio between input and output can be precisely controlled. For example, if the number of planet gears is large or the difference in the number of teeth between the sun gear and the ring gear is large, the gear ratio will increase, and the output speed will decrease, while the torque will correspondingly increase.
3. Low Backlash Characteristic: High-precision planetary gearbox pays particular attention to reducing or eliminating the clearance between gears, known as "zero/low backlash." This is usually achieved through precision processing, preloading technology, and component selection, ensuring extremely high motion precision and smoothness under any load.
4. Dynamic Response and Stability: Due to the evenly distributed load and multiple contact points, the planetary gearbox can provide good dynamic performance, including quick response, stable operation, and durability under heavy loads.
