EtG-SP

Precision Reducer for Servo Motors

EasternGear’s high-precision reducers feature a Globoid tooth profile crafted with proprietary 5-axis precision machining technology, enabling operation through superior Multi-Tooth Contact compared to conventional gears. We offer custom manufacturing tailored to your required specifications, ensuring long-term, error-free, and stable performance in applications such as articulated robots where repeatability is critical, or defense systems that must withstand extreme impacts.

◆ Key Features

  • [High Durability & Shock Absorption] Simultaneous Multi-Tooth Contact Technology
    Multiple gear teeth achieve simultaneous surface contact to distribute loads, delivering over 200% greater durability compared to conventional models and safely protecting the system from unexpected Shock Loads.

  • [Precision Control] Ultra-Precision Backlash (1~3 arcmin)
    By minimizing backlash for precise positional control, we guarantee error-free performance in robotic arms and semiconductor equipment where repeatability is essential.

  • [High Efficiency & Low Noise] Optimized Friction Control
    The broad contact area unique to globoid worm gears lowers pressure per unit area, drastically reducing noise and vibration. Furthermore, optimized tooth design achieves a high transmission efficiency of up to 97%, minimizing energy loss in servo motors.

  • [Custom Manufacturing] Full-Scale Customization from Micro to Large
    We provide tailored design options perfectly suited to your equipment, ranging from micro-sizes with a 17mm Center Distance to large 300mm-class units.



◆ Applications

  • Industrial Robots: High-rigidity joint units for articulated robots.
  • Defense Industry: High-precision targeting and radar drive systems.
  • EV Manufacturing: Automation lines for high-speed, high-precision repetitive tasks.
  • Specialized Environments: Medical and laboratory equipment requiring high torque in confined spaces.
