TR090 Series High Precision Planetary Gearbox Right Angle Reducer Overview

The TR090 Series High Precision Planetary Gearbox Right Angle Reducer is a type of gearbox that is commonly used in industrial automation equipment for precise speed control and positioning, such as robot joint drives and precision machine tool feed mechanisms. It is also known as a servo motor planetary gearbox and a low backlash planetary gearbox. The TR090 Series High Precision Planetary Gearbox Right Angle Reducer is shown in the following image:

高精度遊星ギアボックスの基本構造

The basic structure of a high precision planetary gearbox includes the following components:

• サンギア: Located at the center of the planetary gearbox, the sun gear is typically connected to the input shaft or fixed to the housing as a stationary component.
• プラネットギア： The planet gears rotate around the sun gear and are supported and maintained in their relative positions by a carrier. Each planet gear engages with the sun gear and the ring gear.
• 惑星キャリア: キャリアは、複数の遊星歯車軸穴を備えた構造です。遊星歯車を支持し、太陽歯車に対して相対的に回転することを可能にします。キャリアは出力要素として使用することも、他の軸に接続してトルクを伝達または受け取ることもできます。
• リングギア/アニュラス: The ring gear is a large-diameter ring gear that is fixed inside the housing. Its inner and outer surfaces have teeth that engage with the planet gears. In some applications, the ring gear can also be used as an input or output end.
• ベアリングとシャフトシステム: The bearings in a high precision planetary gearbox support the input shaft, output shaft, and carrier, ensuring smooth and stable rotation and operation of the components.
• ハウジング： The housing is a sturdy structure that encloses all internal components, providing stable support for the gears, protecting them from external impurities, and may include cooling or lubrication systems.
• シャフトとキー: The input and output shafts are connected to the sun gear or carrier through keys to transmit power, ensuring accurate torque transmission and axial positioning.
• シール: Seals are used to prevent lubricating oil leakage and contamination from entering the gearbox, ensuring internal cleanliness and good lubrication status.

高精度遊星ギアボックスの動作原理

The working principle of a high precision planetary gearbox includes the following aspects:

• トルク伝達と増幅: When power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate. Since the planet gears engage with the sun gear and the ring gear at the same time, they begin to revolve and rotate. Due to the joint action of multiple sets of planet gears, the load of the entire system is evenly distributed, which significantly increases the output torque and achieves torque amplification.
• 速度とギア比の制御: By adjusting the tooth count ratio of the sun gear, planet gears, and ring gear, the speed relationship and gear ratio between the input and output can be precisely controlled. For example, if the number of planet gears is large or the tooth count difference between the sun gear and the ring gear is large, the gear ratio increases, the output speed decreases, and the torque increases accordingly.
• 低バックラッシュ特性: High precision planetary gearboxes are particularly focused on reducing or eliminating the backlash between gears, known as "zero/low backlash." This is usually achieved through precision machining, preloading technology, and component selection to ensure high motion accuracy and smoothness under any load.
• 動的応答と安定性: Due to the evenly distributed load and multiple contact points, the planetary gearbox can provide good dynamic performance, including quick response, stable operation, and durability under heavy loads.
