TNF180 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TNF180 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 commonly used in various industries, including robotics, medical equipment, aerospace, and automotive manufacturing. It is designed to provide high precision and low backlash transmission for servo motor applications.

High Precision Planetary Gearbox 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 relative position by the planet carrier. Each planet gear simultaneously meshes with the sun gear and the ring gear, and when power is input, they share and distribute the load.

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 be used as an output component or connected to another shaft to transmit or receive torque.

Ring Gear/Annulus

The ring gear is a large diameter annular gear fixed inside the housing, with teeth on its inner and outer surfaces that mesh with the planet gears. In some applications, the ring gear 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 components.

Housing and Seals

The housing is the external frame of the gearbox that protects internal components from external environmental influences and provides installation interfaces. Seals ensure that the internal lubricating grease does not leak and prevent dust and moisture from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is input to the sun gear, the planet gears around it rotate. As the planet gears mesh with both the sun gear and the ring gear, they rotate around 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 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 can be achieved between the input and output ends. Generally, when the number of planet gears increases or the gear ratio increases, the effect of increasing torque becomes more significant, but the output speed decreases at the same time.

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 the clearance between gears, i.e., "zero/low backlash" design.

Load Distribution and Dynamic Response

One 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.
