The tooth sizes and specifications for the 75 Types Robotic Plastic Gear Pulley Set typically feature a standardized metric Module of 0.5 (M0.5), meaning all gears can seamlessly mesh with each other. [1, 2, 3, 4, 5] The entire kit contains a wide assortment of components ranging from 8 teeth to 56 teeth, with central shaft aperture diameters primarily sized at 2mm (tight or loose fit), alongside a few specialized pieces at 2.3mm and 3.17mm. [1, 2]   Understanding the Model Nomenclature The codes printed on the gears (e.g., 16102B or 81A) reveal their exact dimensions and hole sizes: [1, 2, 3]
  • The first numbers represent the tooth count.
  • The numbers following (in double-layer gears) show the tooth count of the second layer.
  • The suffix "A" means a tight fit on a 2mm shaft (actual hole is ~1.95mm).
  • The suffix "B" means a loose/rotational fit on a 2mm shaft (actual hole is ~2.05mm). [1, 2, 3, 4, 5]
    Detailed Breakdown of Gear Types and Sizes Here is the complete configuration of the 75-piece kit, classified by gear type and tooth size: [1]   1. Spindle Straight Gears (9 Types) These small spur gears attach directly to motor spindles: [1]

  Pitch Diameter Calculation Tip Because these components use the M0.5 metric standard, you can easily determine the physical diameter of any gear using this formula:
\(\text{Pitch\ Diameter\ (mm)}=\text{Number\ of\ Teeth}\times 0.5\)
