Product Description The 78-Piece Plastic Gear Assortment is a comprehensive mechanical hardware kit designed for students, makers, and robotics enthusiasts. This kit provides an extensive variety of gears, including crown gears for 90-degree transmission, worm gears for high reduction, and double-layer gears for complex speed manipulation. Beyond just gears, it includes essential transmission components like rubber belts, pulleys, and plastic axles, making it a complete solution for building custom gearboxes, motorized cars, and robotic arm linkages.

Key Features

  • Comprehensive 78-piece set covering almost all hobby-level transmission needs.

  • High-precision molding ensures smooth meshing and minimal friction loss.

  • Includes specialized gears like Crown and Worm gears for diverse mechanical movements.

  • Comes with varied axle lengths and pulley belts for immediate project assembly.

  • Lightweight and durable plastic construction, perfect for prototyping.

Technical Details

  • Material Composition: Industrial grade ABS plastic.

  • Hole Diameters: Primarily 1.9mm (designed for a tight friction fit on 2mm motor shafts).

  • Gear Variety: Single layer, Double layer, Crown, Spindle, Worm, and Bevel gears.

  • Transmission Parts: Pulley wheels, Rubber belts (various sizes), and Sleeves/Bushings.

  • Axle Dimensions: Assorted lengths of 2mm diameter plastic rods.

  • Standard Modulus: 0.5M (all gears in the kit are compatible with each other).

Prototyping and Engineering Tips from Robogears

  • Shaft Compatibility: Most gears in this kit have a 1.9mm hole. This is intentional to ensure they "bite" onto a standard 2mm DC motor shaft. Use a small flat tool to push them on evenly to avoid bending the motor shaft.

  • Compound Gear Ratios: Use the double-layer gears to create high-torque reductions in a small space. By connecting the small inner gear of one to the large outer gear of the next, you can significantly increase the lifting power of a small motor.

  • Belt Tension: When using the included rubber belts and pulleys, ensure the belt is slightly taut. If it's too loose, it will slip; if it's too tight, it will create excessive friction and stall your motor.

  • Lubrication: While these plastic gears are designed for dry use, a tiny amount of plastic-safe silicone grease can significantly reduce noise and increase the lifespan of your gearbox during high-speed operation.
