key Takeaways<\/h2>\n\n\n\n
    \n
  1. Core Function:<\/strong> Achieves “Speed Reduction, Torque Multiplication,” converting high-speed, low-torque input into the low-speed, high-torque output required by machines.<\/li>\n\n\n\n
  2. Primary Advantages:<\/strong> Most cost-effective, and boasts extremely high transmission efficiency (95%+ per stage), making it easy to integrate.<\/li>\n\n\n\n
  3. Major Drawbacks:<\/strong> High noise (the most significant fault), lower relative load capacity, and moderate backlash (limiting precision).<\/li>\n\n\n\n
  4. Competitive Edge:<\/strong> It is cheaper than Planetary motors; and is more efficient than Worm Gear motors, while also offering back-drivability.<\/li>\n\n\n\n
  5. Structural Types:<\/strong> Available in Cylindrical, Flat\/Square (Box Type, widely used in vending machines<\/strong>), and N20 Miniature forms.<\/li>\n\n\n\n
  6. Typical Applications:<\/strong> Heavily used in vending machines, micro-robotics, light industrial conveyors, and certain medical devices.<\/li>\n\n\n\n
  7. Selection Principle:<\/strong> Must determine the required continuous rated torque (T<\/em>req) and ensure the operating torque is far below the Stall Torque (recommended <30%) for a safety margin.<\/li>\n\n\n\n
  8. Failure Modes:<\/strong> Common faults include tooth wear, breakage, and stripping of the gear teeth (often the first plastic stage under overload).<\/li>\n\n\n\n
  9. Maintenance Point:<\/strong> Synthetic grease (silicone\/PTFE-based) is mandatory for plastic gears; using high-viscosity damping grease is the primary method for noise reduction.<\/li>\n<\/ol>\n\n\n\n
