TE090 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

The TE090 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of gearbox designed for high precision and low backlash applications. It is commonly used in industrial automation equipment, medical devices, aerospace systems, precision instruments, automotive manufacturing, and robotics technology. The gearbox features a high reduction ratio, compact size, and high torsional stiffness, which makes it ideal for applications that require precise motion control and high torque transmission.

Basic Construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of several key components:

• Sun Gear: Located at the center of the planetary gearbox, the sun gear is typically connected to the input shaft or fixed in the housing as a stationary component.
• Planet Gears: The planet gears rotate around the sun gear and are supported by the carrier, which maintains their relative position. Each planet gear engages with the sun gear and the internal ring gear to distribute the load.
• Planet Carrier: The planet carrier is a structure with multiple planet gear shaft holes that supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output element or connect to another shaft to transmit or receive torque.
• Ring Gear/Annulus: The internal ring gear is a large diameter circular gear fixed inside the housing. It has teeth on both the inner and outer surfaces that engage with the planet gears.
• Bearings and Shaft System: The bearings in the high precision planetary gearbox support the input and output shafts as well as the planet carrier, ensuring stable rotation and smooth operation of the components.
• Housing: The housing is a sturdy structure that encloses all the internal components, provides stable support for the gears, and protects the internal components from external contaminants. It may also include cooling or lubrication systems.
• Shafts and Keys: The input and output shafts are connected to the sun gear or planet carrier via keys to transmit power and ensure precise torque transmission and axial positioning.
• Seals: Seals prevent lubricating oil leakage and contamination from entering the gearbox, ensuring clean and well-lubricated internal components.

Working Principle of High Precision Planetary Gearbox

The High Precision Planetary Gearbox works based on three principles:

1. Torque Transmission and Amplification: When power is transmitted from the input shaft to the sun gear, the sun gear starts rotating. As the planet gears engage with the sun gear and the internal ring gear, they begin to revolve and rotate. Because multiple sets of planet gears work together, the load of the entire system is evenly distributed, significantly increasing the torque output and achieving torque amplification.
2. Speed and Gear Ratio Control: By adjusting the gear ratios between the sun gear, planet gears, and internal ring gear, the gearbox can precisely control the speed and gear ratio between the input and output shafts. For example, increasing the number of planet gears or the difference in teeth between the sun gear and the internal ring gear can increase the gear ratio, lower the output speed, and increase the output torque.
3. Low Backlash Characteristics: The High Precision Planetary Gearbox is specially designed to reduce or eliminate the backlash between gears. This is usually achieved through precision machining, preloading techniques, and component selection, ensuring high motion accuracy and smooth operation under any load conditions.
