Product Description
Custom Internal Spur Gear Overview
Our internally toothed annulus gear features teeth on the inner surface of the rim, designed to mesh with external gears for efficient power transmission in compact mechanical systems.
Key Operational Features
- Same-direction rotation when meshing with external gears (unlike external-external gear pairs)
- Compact machine system design enabled by internal-external gear configuration
- Driven by smaller external gears for space-efficient applications
