TNE070 Series High Precision Planetary Gearbox Helical Gear Reducer

TNE070 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TNE070 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 that is widely used in industrial automation equipment. It is designed to provide high precision, low backlash, and high efficiency transmission of power from a motor to a driven load. The gearbox is commonly used in applications that require high precision motion control, such as robotics, CNC machinery, medical equipment, and aerospace technology.

High Precision Planetary Gearbox Basic Construction

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 component.

Planet Gears

The planet gears rotate around the sun gear and are supported and held in their relative positions by the planet carrier. Each planet gear meshes with both the sun gear and the inner ring gear and shares the load when power is applied.

Planet Carrier

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

Ring Gear/Annulus

The ring gear or annulus is a large diameter ring gear fixed inside the gearbox housing with teeth on both inner and outer surfaces. It meshes with the planet gears to transfer torque. In some applications, the ring gear can also be used as an input or output end.

Bearings and Shaft System

Bearings in the high precision planetary gearbox are used to support the input and output shafts as well as the planet carrier, ensuring stable rotation and smooth operation between components.

Housing and Seals

The housing is the external frame of the gearbox that protects internal components from environmental impact and provides mounting interfaces. Seals ensure that the internal lubricant does not leak and prevent dust and water from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is input to the sun gear, the planet gears rotate around the sun gear and also revolve around the sun gear center with the planet carrier. The torque that is input to the sun gear is amplified and evenly distributed to the output planet carrier through the planet gears that mesh with both the sun gear and the inner ring gear.

Speed Conversion and Torque Amplification

Speed conversion and torque amplification between input and output can be achieved by adjusting the gear ratio. Generally, increasing the number of planet gears or the gear ratio leads to an increase in torque, but a decrease in output speed.

Low Backlash Design

To ensure precise position control and minimal mechanical clearance in high precision applications, high precision planetary gearboxes adopt preloading technology to reduce or eliminate gear clearance, known as "zero/low backlash" design.

Load Distribution and Dynamic Response

One of the important advantages of the planetary gear mechanism is that the load is evenly distributed among multiple planet gears, which improves the load capacity and stability of the entire system and optimizes the dynamic response performance.

High Precision Planetary Gearbox Design and Selection Factors

The design and selection of a high precision planetary gearbox should consider the following factors:
