TRE060 Series High Precision Planetary Gearbox Right Angle Reducer

Overview

TRE060 Series High Precision Planetary Gearbox Right Angle Reducer is a type of gearbox that is used to deliver power from a motor to a machine. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. This gearbox is widely used in different industries including automation equipment, robotics, and medical equipment. It is designed to provide an output that is more precise, powerful, and efficient than other types of gearboxes.

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 on the housing as an immovable component.

Planet Gears

The planet gears rotate around the sun gear and are supported by the carrier to maintain their relative position to each other. Each planet gear meshes with the sun gear and the inner ring gear. When power is input, they collectively bear and distribute the load.

Planet Carrier

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

Ring Gear/Annulus

The inner ring gear is a large diameter circular gear fixed inside the housing that has teeth on both its inner and outer surfaces and meshes with the planet gears. In some applications, it can also be used as an input or output end.

Bearings and Shaft System

The bearings in the high precision planetary gearbox are used to support the input and output shafts as well as the carrier to ensure stable rotation and smooth operation of the components.

Housing and Seals

The housing is the outer frame of the gearbox that protects the internal components from external environmental influence and provides installation interfaces. Seals ensure that the internal lubricant does not leak while preventing dust and water from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is input to the sun gear, it drives the planet gears around it. Since the planet gears mesh with both the sun gear and the inner ring gear, they rotate around their own axes while also orbiting the center of the sun gear with the carrier. In this way, the torque input to the sun gear is amplified and evenly distributed to the planet carrier at the output end.

Speed Conversion and Torque Amplification

By adjusting the gear ratio of different components, speed conversion and torque amplification between the input and output can be achieved. Generally, as the number of planet gears increases or the gear ratio increases, the effect of torque amplification becomes more significant, but the output speed will decrease.

Low Backlash Design

In high-precision applications, to ensure precise position control and minimal mechanical clearance, high precision planetary gearboxes use preloading technology to reduce or eliminate gear clearances, that is, "zero/low backlash" design.

Load Distribution and Dynamic Response

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

High Precision Planetary Gearbox Design and Selection Considerations

The following table lists some essential factors to consider when designing and selecting a high precision planetary gearbox.
