Internal gear ring

The internal gear ring is a precision-engineered component featuring teeth cut on the inner diameter of a ring-shaped blank. It is commonly used in planetary gear systems, epicyclic drives, and rotary actuators. Manufactured from high-strength alloy steel or cast iron, the gear ring undergoes heat treatment to ensure excellent wear resistance and dimensional stability. Its internal teeth mesh seamlessly with external planetary gears, enabling high torque transmission within a compact design. Typical applications include automatic transmissions, wind turbine gearboxes, and heavy-duty industrial reducers where reliable, high-ratio speed reduction is required.
