Sun Gear: The central gear, typically serving as the power input component, transferring torque to the planetary gears.
Planetary Gears: Usually 3 to 6 small gears evenly distributed around the sun gear. They mesh simultaneously with the sun gear (externally) and the ring gear (internally), enabling power 分流 (power splitting).
Ring Gear: An internal gear (with teeth on the inner circumference). In most cases, it is fixed to the housing; alternatively, it can act as a power output component depending on the transmission design.
Carrier: A structural component that supports the planetary gears, allowing them to rotate around their own axes (spin) while revolving around the sun gear (revolution). It often functions as the power output part.
High Power Density: Power is split and transmitted through multiple planetary gears, enabling the system to handle high torque within a compact space.
Large Transmission Ratio: It achieves a large speed reduction (or increase) ratio in a limited volume, eliminating the need for bulky gear trains.
High Transmission Efficiency: Multiple pairs of teeth mesh simultaneously during operation, reducing energy loss and maintaining efficiency (typically above 95% for well - designed systems).
Excellent Balance: Radial forces generated by the meshing of planetary gears cancel each other out, minimizing vibration and noise, and enhancing the system's stability.
Positive Shift ((x > 0)): The tool moves away from the gear blank center. This increases the addendum thickness, strengthens the tooth root, and reduces the risk of tooth breakage.
Negative Shift ((x < 0)): The tool moves closer to the gear blank center. It reduces the addendum thickness but can help avoid interference in gear pairs with a small number of teeth.
