TE120 Series High Precision Planetary Gearbox Helical Gear Reducer

TE120 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

TE120 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 used in industrial automation equipment for accurate speed control and position positioning. This gearbox has high precision and low backlash design, which ensures accurate position control and minimum mechanical clearance.

High Precision Planetary Gearbox Basic Construction

The high precision planetary gearbox consists of several components:

• Sun Gear: Located in the center of the planetary gearbox, the sun gear 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 and kept in relative position by the planet carrier. Each planet gear meshes with the sun gear and the ring gear/annulus. When power is input, they share and distribute the load.
• 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/annulus is a large diameter ring gear fixed inside the housing, with teeth on the inside and outside surfaces that mesh with the planet gears. In some applications, the ring gear/annulus can also be used 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, ensuring stable rotation and smooth operation between the components.
• Housing and Seals: The housing is the external frame of the entire gearbox, which protects the internal components from external environmental influences and provides installation interfaces. The seals ensure that the internal lubricant does not leak and prevent dust and water from entering the gearbox.

Explanation of the Basic Construction Components:

1. Sun Gear: The sun gear is the central component of the high precision planetary gearbox that transmits power to the planet gears.
2. Planet Gears: The planet gears rotate around the sun gear and are supported by the planet carrier. They mesh with the sun gear and the ring gear/annulus to distribute the load.
3. Planet Carrier: The planet carrier carries the planet gears and allows them to rotate relative to the sun gear.
4. Ring Gear/Annulus: The ring gear/annulus meshes with the planet gears to provide mechanical output.
5. Bearings and Shaft System: The bearings in the high precision planetary gearbox ensure stable rotation and smooth operation between the components.
6. Housing and Seals: The housing protects the internal components and the seals prevent lubricant leakage from the gearbox.

High Precision Planetary Gearbox Working Principle

The high precision planetary gearbox works on the following principles:

1. Torque Transmission: When power is input to the sun gear, it drives the planet gears to rotate. Since the planet gears mesh with both the sun gear and the ring gear/annulus, they rotate on their own axis and revolve around the center of the sun gear with the planet carrier. In this way, the torque input to the sun gear is amplified by the planet gears and evenly distributed to the output-side planet carrier.
2. 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, when the number of planet gears increases or the gear ratio increases, the effect of torque amplification is more significant, but the output speed will decrease.
3. Low Backlash Design: In high precision applications, to ensure accurate position control and minimum mechanical clearance, high precision planetary gearboxes adopt preloading technology to reduce or eliminate gear clearance, which is called "zero/low backlash" design.
4. 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 load-bearing capacity and stability of the entire system and optimizing dynamic response performance.
