Basic construction of High Precision Planetary Gearbox

The High Precision Planetary Gearbox consists of the following components:

1. Sun Gear: The sun gear is located in the center of the planetary gearbox and is typically connected to the input shaft or fixed to the housing as a stationary component.
2. Planet Gears: The planet gears rotate around the sun gear and are supported and held in relative position to each other by the carrier. Each planet gear engages with both the sun gear and the internal ring gear, and they collectively bear and distribute the load when power is inputted.
3. Planet Carrier: The carrier is a structure with multiple planet gear shaft holes, which supports the planet gears and allows them to rotate relative to the sun gear. The carrier can serve as an output element or be connected to another shaft to transmit or receive torque.
4. Ring Gear/Annulus: The internal ring gear is a large diameter ring 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 ring gear can also serve as an input or output terminal.
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, ensuring stable rotation and smooth operation between the components.
6. Housing and Seals: The housing is the outer frame of the entire gearbox, which protects the internal components from external environmental effects and provides installation interfaces. The seal ensures that the internal lubricating grease does not leak while preventing dust and water from entering the gearbox.

Working principle of High Precision Planetary Gearbox

The working principle of the High Precision Planetary Gearbox is as follows:

1. Torque transmission: When power is inputted to the sun gear, the planet gears rotate around the sun gear. Since the planet gears engage with both the sun gear and the internal ring gear, they rotate about their own axis while revolving with the carrier around the center of the sun gear. In this way, the torque inputted to the sun gear is amplified by the planet gears 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 between input and output and torque amplification can be achieved. Generally speaking, the greater the number of planet gears or gear ratio, the more significant the torque amplification effect, but the output speed will decrease accordingly.
3. Low backlash design: In high-precision applications, in order to ensure accurate position control and minimal mechanical clearance, high-precision planetary gearboxes use preload technology to reduce or eliminate the clearance between gears, which is known as "zero/low backlash" design.
4. Load distribution and dynamic response: An important advantage of the planetary gear mechanism is that it can distribute the load evenly among multiple planet gears, thereby improving the bearing capacity and stability of the entire system and optimizing dynamic response performance.
