Wheel-like parts with teeth cut into the rim. Meshing of the teeth of two gears enables one to move the other thus transmitting power.

Strictly speaking, these are the toothed, interlocking wheels that drive your machine heads. In layman's terms, this is the mechanism that takes your twisting of the tuning pegs, turns it 90%, and applies to the tuning post so that it will wind on more or less of your strings.

Made of hard steel, these are basically wheels with meshing teeth to transmit power between rotating shafts. These are instrumental in affecting the speed ratio of the vehicle.

wheelwork consisting of a connected set of rotating gears by which force is transmitted or motion or torque is changed; "the fool got his tie caught in the geartrain"

Connect the motor to the piston.

gears increase or reduce the power developed by the motor into usable force. Helical gears, planetary gears and spur gears are the most common types of gears.

Spur gears, worm gears, bevel gears, precision gear manufacturers, helical & custom gear manufacturers.
