Gears

Gears play such an important part in machines that they have become the symbol for machinery. They are wheels with teeth that engage or mesh with each other so that they work in pairs to transmit or change motion. They are frequently used to reduce or increase the speed of a motion and they can also change the direc­tion of motion. The line around which a wheel rotates is its axis; gears can change axial motion.

A bevel is a surface that is slanted at angle in relation to another surface. In a bevel gear the teeth are slanted in relation to the plane of the wheel. Bevel gears are useful in changing the direction of motion, the change being in proportion to the angle of the beveled surface. One variation is the spiral bevel gear which has the same relationship to bevel gears as helical gears have to spur gears. With a bevel gear one tooth at a time has to bear the entire load but in the spiral configuration more than one tooth always remains in contact.

The fourth basic type is called the worm gear. Basic­ally a pair consists of the gear itself, a wheel with teeth which meshes with a worm —a screw which is a helix wrapped around a cylinder. A variation is a worm shaped in an hour-glass figure. Worm gears are used primar­ily for changing the direction of axial motion. They move only in paths that are predetermined. Like cams, link­ages are used to change the di­rection of motion, to transmit different kinds of motion, or to provide variations in timing in different parts of a cycle by varying the lengths of the links in relation to each other.
