High-Strength Ring Gears for Robust Power Transmission

What Are Ring Gears?

Ring gears, also called internal gears, have teeth cut along the inner circumference of a ring. Often paired with planetary or pinion gears, they enable smooth torque transfer in compact systems.

Ring gears are critical components in planetary gear sets, automotive differentials, and heavy machinery, delivering precision and high load capacity.

Key Advantages of Ring Gears

• Compact Power Transmission: Perfect for enclosed gear systems.
• High Load Capacity: Large contact area enhances torque transfer.
• Durability: Robust design withstands continuous use.
• Design Flexibility: Works with spur, helical, and planetary gear sets.
• Noise Reduction: Internal meshing reduces vibration.

(Comparison: Unlike spur gears, which transmit power externally, ring gears allow internal meshing for compact and enclosed systems.)
