The transmission of power between shafts by means of a belt connecting pulleys on the shafts.
One of a pair of gears used to connect two shafts whose axes intersect.
Cam & Follower
A pear-shaped disk with an off-center pivot point, used to change rotating motion into reciprocating motion.
Crank & Slider
A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.
Crown & Pinion
A small cogwheel that engages or is engaged by a larger cogwheel.
The gear which transmits power and motion to the rest of the system. The input gear.
The member of a pair of gears to which motion and power are transmitted by the other. The output gear.
The ability to do work.
A push or pull on an object.
A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.
The ratio of the speed of the driving member of a gear train to that of the driven member.
A gear between the driver and the driven gear used to change rotational direction.

A swing back and forth at a regular rate.
The results of the operation of any system.
The distance between adjacent threads in a screw.
Rack & Pinion
A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.
The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
