Precision internal gears and ring gears for planetary gear systems, epicyclic drives, and complex gear mechanisms. CNC shaped with tight involute profile tolerances for aerospace, robotics, and industrial OEM applications.
Internal gears (ring gears) have teeth cut on the inside diameter of a cylindrical blank. They are fundamental components in planetary gear systems, epicyclic drives, and compact gear arrangements where external gears mesh with the internal teeth from inside the ring.
INSCO manufactures internal spur gears using CNC gear shaping equipment. The Liebherr LORENZ LS 156 CNC shaper and Fellows 36-6 shaper produce internal gears with controlled involute profile, accurate pitch, and tight tooth thickness tolerances.
Internal gears from INSCO serve planetary gear systems in robotics joint actuators, aerospace mechanisms, compact industrial gearboxes, and any application requiring the space efficiency and load distribution of a planetary drive architecture.
