Planetary Reducer: High-Precision Power Transmission Solution

Planetary Gearbox | Precision Planetary Reducer | Servo Planetary Gearbox | Industrial Gear Reducer

A Planetary Reducer (Epicyclic Gearbox) is a compact, high-efficiency power transmission device that delivers torque multiplication and precise speed reduction via a core structure of sun gear, planet gears, internal ring gear, and planet carrier. Engineered for industrial reliability, it’s the go-to choice for demanding motion control applications globally.

Core Structure & Working Principle

Key components work in synergy: the sun gear drives orbiting planet gears (meshed with the ring gear), transferring torque to the planet carrier and output shaft. Modular configurations support multiple modes: speed reduction (ring gear fixed/sun gear input), reverse rotation (carrier fixed), and customized dual-input solutions. Multi-stage gear sets enable enhanced reduction ratios.
Working Principle
  • Ring gear fixed, sun gear input, carrier output: Standard speed reduction (most common)
  • Sun gear fixed, ring gear input, carrier output: Alternative reduction mode
  • Carrier fixed, sun gear input, ring gear output: Reverse rotation reduction
  • Dual input configuration: Customized motion control solutions
