a gear the center of the next consecutive
tooth measured of the pitch
Addendum - ✔✔The portion of the gear tooth that projects
above or outside the pitch circle
Deddendum - ✔✔The portion of the gear tooth space that is
cut below the pitch circle and is equal to the
addendum plus the clearance

, Gear Rack - ✔✔When meshed with a gear it is used to
change rotary motion to reciprocating
motion
Worm Gear - ✔✔A kind of gears for heavy duty works where
a large ratio of speed is required and are
extensively used in speed reducers
Bevel Gear - ✔✔A kind of gear to transmit motion from one
shaft to another shaft at an angle to the first
Normalizing - ✔✔The uniform heating of steel above the usual
hardening temperatures, followed by
cooling freely in air
Quenching - ✔✔The operation of cooling a heated piece of
work rapidly by dipping it in water, brine or
oil
Annhealing - ✔✔A method in softening a piece of metal that is
too hard to machine and is done by heating steel
slowly above the usual hardening temperature
keeping it at the heat for ½ to 2 hours then
cooling slowly, preferably in a furnace
