The basic structure of the high precision planetary gearbox includes several key components:

• Sun Gear: Located at the center of the planetary gearbox, the sun gear is usually connected to the input shaft or fixed to the housing as a stationary component.
• Planet Gears: These gears orbit and 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 ring gear/annulus, and they jointly bear and distribute the load when power is input.
• Planet Carrier: The planet carrier is a structure with multiple planet gear shaft holes, which carries the planet gears and allows them to rotate relative to the sun gear. The planet carrier can serve as an output component or be connected to another shaft to transmit or receive torque.
• Δακτύλιος/Δακτύλιος: The ring gear/annulus is a large diameter ring gear fixed inside the housing, with teeth on both the inner and outer surfaces that mesh with the planet gears. In some applications, the ring gear/annulus can also serve as an input or output end.
• Σύστημα ρουλεμάν και άξονα: The bearings in the high precision planetary gearbox support the input shaft, output shaft, and planet carrier, ensuring stable rotation and smooth operation between components.
• Στέγαση: The housing is a sturdy structure that encloses all internal components, providing stable support for the gears and protecting the internal components from external impurities. It may also contain cooling or lubrication systems.
• Άξονες και κλειδιά: The input and output shafts are connected to the sun gear or the planet carrier via keys to transmit power, ensuring precise torque transmission and axial positioning.
• Σφραγίδες: Seals are used to prevent lubricating oil leakage and contamination from entering the gearbox, ensuring internal cleanliness and good lubrication condition.

Αρχή λειτουργίας του πλανητικού κιβωτίου ταχυτήτων υψηλής ακρίβειας

The high precision planetary gearbox works through the following principles:

• Μετάδοση και Ενίσχυση Ροπής: When the power is transmitted from the input shaft to the sun gear, the sun gear starts to rotate. Since the planet gears mesh with the sun gear and the ring gear/annulus at the same time, they start to revolve and rotate. Due to the joint action of multiple sets of planet gears, the load of the whole system is evenly distributed, which can significantly increase the output torque and achieve torque amplification.
• Control of Speed and Transmission Ratio: By adjusting the tooth number ratio of the sun gear, planet gears, and ring gear/annulus, 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 between the tooth numbers of the sun gear and the ring gear/annulus is larger, the transmission ratio increases, the output speed decreases, and the torque correspondingly increases.
• Χαρακτηριστικά χαμηλής οπισθοδρόμησης: High-precision planetary gearbox specifically focuses on reducing or eliminating the backlash between gears, known as "zero/low backlash." This is usually achieved through precision machining, preloading techniques, and component selection to ensure high motion accuracy and smoothness under any load.
• Δυναμική Απόκριση και Σταθερότητα: Due to the even load distribution and multiple contact points, the high precision planetary gearbox can provide good dynamic performance, including fast response, stable operation, and durability under heavy loads.
