Internal Gear Definition

An internal gear is a special type of gear whose teeth are located on the inner surface, not on the outer surface. It is generally used in planetary gear systems, gearboxes and mechanical power transmission systems. Internal gears are widely preferred in industry due to their compact design and high torque transmission capacity.

Features of Internal Gears

✔ Compact Design - Provides high power transmission in smaller spaces.

Quiet and Smooth Operation - Produces less noise and vibration compared to external gears.

Higher Power Transmission - Works efficiently in combination with planetary gear systems.

Possibility of Reverse Directional Movement - The outer gear working with the internal gear rotates in the same direction.

Usage Areas of Internal Gears

- Planetary Gear Systems (Automotive transmissions, wind turbines)

- Gearboxes (for speed and torque control)

- Hydraulic Motors and Pumps

- Heavy Industrial Machinery
