Overview of TEG080 Series High Precision Planetary Gearbox Helical Gear Reducer

The TEG080 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox used for precision motion control applications. It is designed to provide high precision, low backlash, and high torque capacity in a compact and lightweight package. It is also known as a servo motor planetary gearbox and low backlash planetary gearbox. The gearbox is shown below.

Basic Construction of High Precision Planetary Gearbox

The high precision planetary gearbox consists of several key components. These include:

• Sun Gear: located at the center of the planetary gearbox, usually connected to the input shaft or fixed to the housing as a stationary component.
• Planet Gears: rotate around the sun gear and are supported and maintained in their relative positions by the planet carrier. Each planet gear meshes with the sun gear and internal gear simultaneously, sharing and distributing the load when power is input.
• Planet Carrier: is a structure with multiple planet gear shaft holes, which carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output member or be connected to another shaft to transmit or receive torque.
• Ring Gear/Annulus: is a large diameter circular gear fixed inside the housing, which meshes with the planet gears. In some applications, the internal gear can also serve as an input or output end.
• Bearings and Shaft System: used to support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation between components.
• Housing: is a sturdy structure that encapsulates all internal components, providing a stable support environment for the gears, protecting 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 by keys to transmit power, ensuring accurate torque transmission and axial positioning.
• Seals: used to prevent lubricating oil leakage and prevent contaminants from entering the gearbox, ensuring cleanliness and good lubrication status inside the gearbox.

Working Principle of High Precision Planetary Gearbox

The high precision planetary gearbox works by transmitting power from the input shaft to the sun gear, which begins to rotate. Since the planet gears mesh with both the sun gear and the internal gear, they begin to orbit and rotate at the same time. Due to the combined action of multiple sets of planet gears, the load is evenly distributed throughout the entire system, which significantly increases the output torque and achieves torque amplification. The speed and transmission ratio between the input and output can be precisely controlled by adjusting the number of planet gears or the difference in the number of teeth between the sun gear and internal gear. The gearbox is designed to have a low backlash characteristic. This is achieved through precision processing, preloading technology, and component selection, which ensures high motion accuracy and smoothness under any load. The high precision planetary gearbox can provide excellent dynamic performance due to its uniform load distribution and multiple contact points, including rapid response, stable operation, and durability under heavy loads.
