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"
Toothed machine parts for transmitting power from one shaft to another.
It is a toothed machine part that meshes with another toothed part to transmit motion or to change speed or direction.
Wheels with meshing teeth to transmit power between rotating shafts. When the gear wheels are of different sizes, a change in speed ratio occurs. Gears are made of hard steel.
Circular, wheel-shaped parts with teeth along the edges. The interlocking of two of these mechanisms enables one to turn the other.
Mechanical devices containing teeth that mesh that transmit power, or turning force, from one shaft to another.
