Internal Gearing

Internal gearing is a type of gear where the teeth are cut on the internal surface of a cylinder or crown. These components are used to transmit motion between two coaxial shafts, typically in combination with external cylindrical gears. The internal gearing configuration allows for a reduction in axial space, making it ideal for applications where space is limited or greater compactness of the transmission system is required.

Internal gearing ensures precise and stable coupling, with better containment of radial forces and reduced wear over time. They are employed in high-precision sectors such as robotics, gearmotors, industrial transmissions, and special machinery, where reliability and long-term durability are fundamental.
