TRE110 Series High Precision Planetary Gearbox Right Angle Reducer

Overview

TRE110 Series High Precision Planetary Gearbox Right Angle Reducer, also known as servo motor planetary gearbox and low backlash planetary gearbox, is a type of gearbox that delivers high precision motion control and torque transmission. It is widely used in various industrial applications such as robotics, semiconductor manufacturing equipment, and medical devices.

High Precision Planetary Gearbox Basic Structure

Sun Gear

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

Planet Gears

The planet gears rotate 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, sharing and distributing the load when power is input.

Planet Carrier

The 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 be used as an output component or connected to another shaft to transmit or receive torque.

Ring Gear/Annulus

The ring gear is a large-diameter ring gear fixed inside the housing with teeth on both the inside and outside surfaces that mesh with the planet gears. In some applications, the ring gear can also function 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 to ensure stable rotation and smooth operation of the components.

Housing and Seals

The housing is the external frame of the gearbox, which protects the internal components from external environmental impacts and provides installation interfaces. The seals ensure that the internal grease does not leak while preventing dust and water from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is input into the sun gear, the planet gears rotate around it. Since the planet gears mesh with both the sun gear and the ring gear, they rotate on their own axis while revolving around the center of the sun gear with the planet carrier. Thus, the torque input to the sun gear is magnified and evenly distributed to the planet carrier at 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, a larger number of planet gears or gear ratios results in greater torque amplification, but the output speed is reduced.

Low Backlash Design

In high precision applications, preload technology is used in high precision planetary gearboxes to reduce or eliminate the gap between gears, known as "zero/low backlash" design. This ensures precise position control and minimal mechanical clearance.

Load Distribution and Dynamic Response

One major advantage of the planetary gear mechanism is that it distributes the load evenly among multiple planet gears, improving the overall load-bearing capacity and stability of the system, and optimizing dynamic response performance.
