Spur Gear (3mm) 15 Teeth

The Spur Gear (3mm) 15 Teeth is a spur gear with 15 straight-cut teeth, listed in the 3 mm size. Spur gears transfer motion between parallel shafts, and a 15-tooth gear can work either as the driven gear for a small motor pinion or as the driving gear for a larger wheel, which makes it a flexible choice for robots, models and DIY mechanisms.

Spur Gear (3mm) 15 Teeth Specifications

Spur Gear (3mm) 15 Teeth Applications

• Speed-reduction gear trains driven by small motors
• Small robot drives and moving mechanisms
• Repairing gears in toys, models and small devices
• STEM lessons on gear ratios and mechanics

What's in the Box

• 1 × 15-tooth spur gear

Tip: Gears only mesh smoothly when they share the same module (tooth size), so check this before pairing them. The gear ratio is the driven gear's teeth divided by the driving gear's teeth: an 8-tooth pinion driving this 15-tooth gear gives a 1.875:1 reduction, so the output turns slower but with more torque.
