TE090 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TE090 Series High Precision Planetary Gearbox Helical Gear Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a high-precision mechanical component widely used in various fields of machinery. It is designed to reduce the input speed and increase the output torque of a motor to meet the specific requirements of different applications.

High Precision Planetary Gearbox Construction

Sun Gear

The sun gear is located in the center of the planetary gearbox and is usually connected to the input shaft or fixed to the housing as a stationary component.

Planet Gears

The planet gears rotate around the sun gear and are supported by and maintain their relative positions through the planet carrier. Each planet gear engages with the sun gear and the ring gear/annulus simultaneously, and when power is input, they together bear and distribute the load.

Planet Carrier

The planet carrier is a structure with multiple planet gear axial holes, which supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output component or be connected to another shaft to transmit or receive torque.

Ring Gear/Annulus

The ring gear/annulus is a large diameter ring gear fixed inside the housing with teeth on both its inner and outer surfaces, which engage with the planet gears. In some applications, the ring gear/annulus can also serve as an input or output end.

Bearings and Shaft System

Bearings in the high-precision planetary gearbox support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation of the components.

Housing and Seals

The housing is the external frame of the entire gearbox, protecting the internal components from external environmental influences and providing installation interfaces. Seals ensure that internal lubricants do not leak and prevent dust and water from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is input to the sun gear, the planet gears rotate around the sun gear. As the planet gears engage with both the sun gear and the ring gear/annulus, they rotate themselves around their own axis while revolving around the center of the sun gear through the planet carrier. In this way, the torque input to the sun gear is amplified and evenly distributed to the planet carrier on the output end through the planet gears.

Speed Conversion and Torque Amplification

By adjusting the gear ratio of different components, speed conversion and torque amplification between input and output can be achieved. Generally, increasing the number of planet gears or the gear ratio results in a more significant increase in torque but a decrease in output speed.

Low Backlash Design

In high-precision applications, to ensure accurate position control and minimal mechanical clearance, high-precision planetary gearboxes adopt preload technology to reduce or eliminate the clearance between gears, i.e., "zero/low backlash" design.

Load Distribution and Dynamic Response

An essential advantage of planetary gear mechanisms is that they can evenly distribute loads among multiple planet gears, thereby improving the bearing capacity and stability of the entire system and optimizing dynamic response performance.
