Internal Gear is a precision transmission component with teeth machined on the inner circumference of a ring-shaped gear body. It meshes with external gears to transmit torque while maintaining compact center distance.
Compared with conventional external gears, Internal Gear offers:
• More compact structural design
• Higher space utilization
• Stable multi-tooth meshing
• Lower vibration and noise
• Higher transmission efficiency
• Larger achievable reduction ratios
