Overview of TD200 Series High Precision Planetary Gearbox Helical Gear Reducer

TD200 Series High Precision Planetary Gearbox Helical Gear Reducer is a type of gearbox that is used to transmit torque from one rotating device to another. It is also known as servo motor planetary gearbox and low backlash planetary gearbox. The image of TD200 Series High Precision Planetary Gearbox Helical Gear Reducer is shown below:

高精度遊星ギアボックスの基本構造

The basic construction of High Precision Planetary Gearbox includes the following components:

• サンギア: located at the center of the planetary gearbox, usually connected with the input shaft or fixed on the housing as a stationary part.
• プラネットギア： rotate around the sun gear, supported and held in relative position to each other by a planet carrier. Each planet gear engages with both sun gear and ring gear. They share and distribute the load together when power is input.
• 惑星キャリア: a structure with multiple planet gear shaft holes, carrying planet gears and allowing them to rotate relative to the sun gear. The planet carrier can function as an output element or connect with another shaft to transmit or receive torque.
• リングギア/アニュラス: a large diameter ring gear fixed inside the housing, with teeth on both internal and external surfaces, engages with planet gears. In some applications, the ring gear can also function as input or output end.
• ベアリングとシャフトシステム: bearings in high precision planetary gearbox support input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation among components.
• ハウジング： a sturdy structure that encloses all internal components, providing stable support for gears, protecting internal components from external impurities, and may contain cooling or lubrication systems.
• シャフトとキー: input and output shafts connect to the sun gear or planet carrier via keys to transmit power, ensuring accurate torque transmission and axial positioning.
• シール: seals prevent lubricating oil leakage and pollutant intrusion into the gearbox, ensuring internal cleanliness and good lubrication.

Working Principles of High Precision Planetary Gearbox

The working principles of High Precision Planetary Gearbox are as follows:

1. トルクの伝達と増幅: when power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate. Planet gears start to revolve and rotate because of engaging with sun gear and ring gear at the same time. Due to the joint action of multiple groups of planet gears, the load of the whole system is evenly distributed, which can significantly increase the torque at the output end and achieve torque amplification.
2. 速度と伝達比の制御: by adjusting the tooth number ratio of the sun gear, planet gears, and ring gear, the speed relationship and transmission ratio between input and output can be precisely controlled. For example, if there are more planet gears or the difference in tooth number between the sun gear and ring gear is greater, the transmission ratio increases, the output speed decreases, and the torque increases accordingly.
3. 低バックラッシュ機能: 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.
4. 動的応答と安定性: due to the evenly distributed load and multiple contact points, the planetary gearbox can provide excellent dynamic performance, including fast response, stable operation, and durability under heavy loads.
