TFR160 Series High Precision Planetary Gearbox Helical Gear Reducer

TFR160 Series High Precision Planetary Gearbox Helical Gear Reducer Overview

TFR160 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that is used to reduce the speed of a motor and increase the torque output. It is also known as servo motor planetary gearbox and low backlash planetary gearbox.

High Precision Planetary Gearbox Basic Structure

High Precision Planetary Gearbox is made up 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 held in position relative to each other by the planet carrier. Each planet gear meshes with the sun gear and the ring gear/annulus, and they jointly bear and distribute the load when power is inputted.
• 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 element or connected to another shaft to transmit or receive torque.
• Ring Gear/Annulus: The annulus is a large-diameter ring gear fixed inside the housing with teeth on its inner and outer surfaces that mesh with the planet gears. In some applications, the annulus can also serve as an input or output terminal.
• 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 each component.
• Housing and Seals: The housing is the external frame of the entire gearbox, which protects the internal components from external environmental influences and provides mounting interfaces. The seals ensure that the internal lubricant does not leak and prevent dust and moisture from entering the gearbox.

High Precision Planetary Gearbox Working Principle

The working principle of the High Precision Planetary Gearbox can be explained as follows:

• Torque Transmission: When power is inputted to the sun gear, the planet gears rotate around the sun gear. Since each planet gear meshes with the sun gear and the annulus, they rotate on their own axes and revolve around the center of the sun gear together with the planet carrier. In this way, the torque inputted to the sun gear is amplified through the planet gears and evenly distributed to the planet carrier at the output terminal.
• Speed Conversion and Torque Amplification: By adjusting the gear ratio of different components, speed conversion between input and output and torque amplification can be achieved. Generally, when the number of planet gears increases or the gear ratio increases, the effect of torque amplification becomes more significant, but the output speed decreases at the same time.
• Low Backlash Design: In high-precision applications, in order to ensure precise position control and minimal mechanical clearance, high-precision planetary gearboxes use preloading technology to reduce or eliminate the clearance between gears, which is 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 load-bearing capacity and stability of the entire system, and optimizing dynamic response performance.
