TNE155 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

TNE155 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that is designed to provide high precision and low backlash in various industrial applications. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. This gearbox is commonly used in applications that require high performance and precise motion control, such as robotics, medical equipment, aerospace, and automotive industries.

High Precision Planetary Gearbox Basic Construction

The high precision planetary gearbox consists of several components, including the sun gear, planet gears, planet carrier, ring gear/annulus, bearings and shaft system, housing, shafts and keys, and seals. Each component performs a specific function to ensure the gearbox's smooth operation and high precision.

1. 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 casing as a stationary component.

2. Planet Gears

The planet gears rotate around the sun gear and are supported and held in position relative to each other by the planet carrier. Each planet gear meshes with both the sun gear and the ring gear/annulus, distributing the load when power is inputted.

3. Planet Carrier

The planet carrier is a structure with multiple planet gear shaft holes. It carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can act as an output element or can be connected to another shaft to transmit or receive torque.

4. Ring Gear/Annulus

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

5. 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 between components.

6. Housing

The housing is a robust structure that encapsulates all the internal components, provides stable support for the gears, protects the internal components from external impurities and may contain cooling or lubrication systems.

7. Shafts and Keys

The input and output shafts are connected to the sun gear or planet carrier by keys to transfer power and maintain accurate torque transfer and axial positioning.

8. Seals

The seals prevent lubricating oil leakage and contaminants from entering the gearbox, ensuring a clean and well-lubricated internal environment.

High Precision Planetary Gearbox Working Principle

The high precision planetary gearbox operates by transferring and amplifying torque, controlling speed and gear ratios, and providing low backlash. The gearbox uses the interaction between the sun gear, planet gears, and ring gear/annulus to transfer and distribute power output. The gearbox's precise gear ratio and torque amplification are achieved by adjusting the teeth number and size of the sun gear, planet gears, and ring gear/annulus.
