• Specification

• Function

1. Forming the Planetary Gear System
In a planetary gear set, the Gear Ring is the outermost component, surrounding the sun gear (center) and planet gears (between the sun and ring). Together, these elements create a compact, high - torque transmission system.

2. Torque Transmission and Multiplication
Fixed Ring Gear: When the Gear Ring is held stationary (e.g., locked by a brake), the planet gears rotate around the sun gear while also orbiting it. This configuration increases torque output while reducing speed, ideal for heavy - duty applications like lifting or digging in construction equipment.
