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 high-precision gearbox that is widely used in industries that require accurate motion control and torque amplification. The gearbox features a compact design, high torque density, low backlash, and high precision. It provides smooth, reliable, and efficient power transmission and motion control.

Basic Construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of the following components:

• Sun Gear: located at the center of the planetary gearbox, usually connected to the input shaft or fixed to the housing as a stationary component.
• Planet Gears: rotate around the sun gear and are supported and held in place relative to each other by the planet carrier. Each planet gear meshes with the sun gear and the ring gear/annulus, and they collectively bear and distribute the load when power is transmitted.
• Planet Carrier: 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 serve as an output element or be connected to another shaft to transmit or receive torque.
• Ring Gear/Annulus: a large-diameter ring-shaped gear fixed inside the housing, with teeth on both its inner and outer surfaces meshing with the planet gears. In some applications, the ring gear can also serve as an input or output end.
• 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 the components.
• Housing: a sturdy structure that encapsulates all internal components, providing stable support for the gears and protecting the interior from external impurities. It may also contain a cooling or lubrication system.
• Shafts and Keys: the input shaft and output shaft are connected to the sun gear or planet carrier via keys to transmit power and ensure precise torque transmission and axial positioning.
• Seals: seals prevent lubricating oil leakage and contamination from entering the gearbox, ensuring a clean and well-lubricated internal environment.

Working Principle of High Precision Planetary Gearbox

The High Precision Planetary Gearbox works by:

• Transferring and amplifying torque: When power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate, and the planet gears start to revolve and rotate due to their simultaneous meshing with the sun gear and the ring gear. The load is evenly distributed among them because of the combined action of multiple sets of planet gears, which significantly increases the torque at the output end and achieves torque amplification.
• Controlling speed and transmission ratio: By adjusting the ratio of teeth on the sun gear, planet gears, and ring gear, the speed relationship and transmission ratio between the input and output can be precisely controlled. For example, if there are more planet gears or a larger difference between the number of teeth on the sun gear and the ring gear, the transmission ratio increases, and the output speed decreases, while the torque correspondingly increases.
• Low backlash: High Precision Planetary Gearbox pays special attention to reducing or eliminating the clearance between gears, known as "zero/low backlash." This is usually achieved through precision machining, preloading technology, and component selection, ensuring extremely high motion accuracy and smoothness under any load.
• Dynamic response and stability: Due to the evenly distributed load and multiple contact points, the High Precision Planetary Gearbox can provide excellent dynamic performance, including quick response, stable operation, and durability under heavy loads.
