Typical Applications of Internal Gears
Our DIN 5 precision ring gears are engineered for high-performance planetary gearboxes used in demanding industrial applications:
- Sugar Mill Drives: Critical component in planetary reducers for cane crushers, ensuring continuous 24/7 operation under heavy shock loads with minimal vibration
- Servo & Precision Planetary Gearboxes: Ideal for applications requiring high positional accuracy and repeatability, such as CNC machine tools and automated assembly lines
- Robotics & Automation: Perfect for robot joint gearboxes (including collaborative robots) where low backlash and smooth motion are essential
- Heavy Industrial Equipment: Mining conveyors, cement mills, and metallurgical machinery that demand high torque density and long-term reliability
- Renewable Energy: Wind turbine pitch and yaw drives requiring precision gearing under variable loads

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.
