Product Description

Overview of TD090 Series High Precision Planetary Gearbox Helical Gear Reducer

TD090 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox used in various industrial applications. It is known by several other names, such as servo motor planetary gearbox and low backlash planetary gearbox. The gearbox has a high precision design that provides accurate and efficient transmission of power. The TD090 series gearbox is made up of a helical gearbox and planetary gearbox that work together to provide precision motion control.

Basic Construction of High Precision Planetary Gearbox

The high precision planetary gearbox consists of the following components:

Sun Gear
The sun gear is located at the center of the planetary gearbox and is typically 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 and held in place relative to each other by the planet carrier. Each planet gear meshes with both the sun gear and the ring gear, and they share and distribute the load when power is input.
Planet Carrier
The planet carrier is a structure with multiple planet gear shaft holes. It supports the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output element or be connected to another shaft to transmit or receive torque.
Ring Gear/Annulus
The ring gear is a large diameter ring-shaped gear fixed inside the housing with teeth on both its inner and outer surfaces that mesh with the planet gears. In some applications, the ring gear can also serve as the 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 between the components.
Housing and Seals
The housing is the external frame of the entire gearbox that protects the internal components from external environmental effects and provides installation interfaces. Seals ensure that internal lubricants do not leak and prevent dust and water from entering the gearbox.

Working Principle of High Precision Planetary Gearbox

The working principle of the high precision planetary gearbox is as follows:

Torque Transmission
When power is input to the sun gear, the planet gears around it rotate. Since the planet gears mesh with both the sun gear and the ring gear, they undergo self-rotation on their own axis while revolving around the center of the sun gear with the planet carrier. In this way, the torque input to the sun gear is amplified through the planet gears 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 between input and output, as well as torque amplification can be achieved. Typically, increasing the number of planet gears or gear ratio results in a more significant increase in torque but also 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 use preloading technology to reduce or eliminate the clearance between gears, known as "zero/low backlash" design.
Load Distribution and Dynamic Response
An important advantage of the planetary gear mechanism is that it 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.
