Overview of TRH110 Series High Precision Planetary Gearbox Right Angle Reducer

The TRH110 Series High Precision Planetary Gearbox Right Angle Reducer is a type of gearbox used for high precision and high torque applications. It is also known as a servo motor planetary gearbox or a low backlash planetary gearbox. The gearbox is shown in the following image:

Basic Construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of the following components:

1. Sun Gear: The central gear in the planetary gear system, usually connected to the input shaft or fixed to the housing as a stationary element.
2. Planet Gears: Gears that rotate around the sun gear and are supported and held in relative position to each other by the planet carrier. Each planet gear meshes with both the sun gear and the internal gear, and when power is input, they share and distribute the load together.
3. Planet Carrier: A structure with multiple planet gear shaft holes, which 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.
4. Ring Gear/Annulus: A large diameter circular gear fixed inside the housing with teeth on both its inner and outer surfaces that mesh with the planet gears. In some applications, the internal gear can also serve as an input or output end.
5. Bearings and Shaft System: The bearings in the High Precision Planetary Gearbox support the input and output shafts as well as the planet carrier to ensure stable rotation and smooth operation of all components.
6. Housing and Seals: The housing is the external framework of the gearbox, which protects internal components from external environmental influence and provides installation interfaces. The seals ensure that the internal lubricant does not leak and prevent dust and water from entering the gearbox.

Explanation of each component

1. The sun gear is the central gear in the planetary gear system and rotates around its own axis while the planet gears revolve around it.
2. The planet gears rotate around the sun gear and mesh with both the sun gear and the internal gear.
3. The planet carrier supports the planet gears and allows them to rotate around the sun gear. It can be used as an output element or connected to another shaft to transmit or receive torque.
4. The ring gear is fixed inside the housing and meshes with the planet gears.
5. The bearings support the input and output shafts as well as the planet carrier to ensure stable rotation and smooth operation of all components.
6. The housing protects internal components from external environmental influence and provides installation interfaces. The seals ensure that the internal lubricant does not leak and prevent dust and water from entering the gearbox.

The High Precision Planetary Gearbox works by:

Working Principle of High Precision Planetary Gearbox

1. Torque transmission: When power is input to the sun gear, it drives the surrounding planet gears to rotate. Since the planet gears mesh with both the sun gear and the internal gear, they rotate on their own axis while revolving around the sun gear center along with the planet carrier. In this way, the torque input to the sun gear is amplified and evenly distributed to the planet carrier at the output end.
2. Speed conversion and torque amplification: By adjusting the gear ratio of different components, speed conversion and torque amplification between input and output 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 will decrease at the same time.
3. Low backlash design: In high precision applications, to ensure accurate position control and minimum mechanical clearance, high precision planetary gearboxes use preloading technology to reduce or eliminate gear clearance, i.e., "zero/low backlash" design.
4. 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 overall load-bearing capacity and stability of the system, and optimizing dynamic response performance.
