TDR064 Series High Precision Planetary Gearbox Helical Gear Reducer

TDR064 Series High Precision Planetary Gearbox Helical Gear Reducer

Overview

TDR064 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 designed to provide high precision and rigidity in various applications. This gearbox is widely used in industrial automation, medical equipment, aerospace, precision instruments, automotive manufacturing, robotics, and logistics automation.

High Precision Planetary Gearbox Basic Structure

Sun Gear

The sun gear is located at the center of the planetary gear and is usually connected to the input shaft or fixed to the housing as a stationary element.

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 engages with both the sun gear and the ring gear, and when power is inputted, they jointly distribute and carry the load.

Planet Carrier

The planet carrier is a structure with multiple planet gear shaft holes. It 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 housing. It has teeth on both the inner and outer surfaces and engages 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 and output shafts as well as the planet carrier. They ensure stable rotation and smooth operation of 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 installation interfaces. Seals ensure that internal lubricants do not leak and prevent dust and moisture from entering the gearbox.

High Precision Planetary Gearbox Working Principle

Torque Transmission

When power is inputted to the sun gear, it drives the planet gears to rotate around the sun gear. Since the planet gears engage with both the sun gear and the ring gear, they perform self-rotation on their own axis while revolving around the center of the sun gear with the planet carrier. In this way, the torque inputted to the sun gear is amplified and evenly distributed to the planet carrier at the output.

Speed Conversion and Torque Amplification

By adjusting the gear ratio of different components, speed conversion and torque amplification between the input and output can be achieved. Generally, increasing the number of planet gears or gear ratios will result in a more significant increase in torque, but the output speed will decrease.

Low Backlash Design

In high-precision applications, to ensure accurate position control and minimal mechanical clearance, high-precision planetary gearboxes use preload technology to reduce or eliminate the gap between gears, also known as "zero/low backlash" design.

Load Distribution and Dynamic Response

One important advantage of the planetary gear mechanism is that it distributes the load evenly among multiple planet gears, thus improving the load-bearing capacity and stability of the entire system and optimizing dynamic response performance.

High Precision Planetary Gearbox Design and Selection Factors

Factors	Explanation
Speed ratio	The ratio of input speed to output speed is an important factor in determining the required gearbox.
Load capacity	The gearbox's maximum torque rating must be determined to ensure it can handle the applied load.
Size and weight	The size and weight of the gearbox must be considered to ensure it can be properly mounted and does not add unnecessary weight to the system.
Noise and vibration	These factors must be considered when selecting a gearbox to ensure it does not adversely affect the system's performance or operation.
Environmental conditions	The gearbox must be able to withstand the environmental conditions in which it will operate, including temperature, humidity, and exposure to chemicals or other substances.
