This small size internal ring gears use power skiving crafts. This cutting method works well for tiny gears with tight inner diameters — down to 20mm bore and 0.5 module. Unlike broaching, skiving lets us cut internal teeth quickly without custom tooling for every size.

Typical Applications Of Internal Gears By Power Skiving
This small size internal ring gear is used in the leg joints of quadruped robots — shoulders, hips, knees, and ankles. Each joint has a compact planetary reducer, and the ring gear sits fixed inside the actuator housing. The planet gears roll through it, reducing motor speed while multiplying torque for walking, trotting, or jumping. Power skiving allows us to cut these tiny internal teeth efficiently.

Tube Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Internal Gear Shapping
Gear shaping is a gear cutting process that used cutting tool that is essentially a “master gear” reciprocates while meshing in a synchronized rolling motion with the gear blank.The cutter is usually moving up and down.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
Ring Gear Grinding
Gear Grinding is the the most common high-precision method for finishing hardened gears under gleason profile. There are two methods to use an abrasive grinding wheel removes material from the tooth flanks.
