Mechanical gears are rotating machines with cogs or
cut teeth. They mesh with some other toothed part for transmitting torque.
Devices that are geared can alter the torque, speed and also direction of the
power source. Gears and shafts are
inseparable parts of certain vehicles. Gears and shafts are of two types- external gear
and internal gear. In an external gear, the teeth are present on the cone or
cylinder’s outer side. In an internal gear, the teeth are present on the cone
or cylinder’s inner side. Internal gears cannot cause direction reversal of the
output shaft. Some of the common types are spur, skew gears, helical, bevel,
hypoid, non-circular, crown, sun and planet etc.

used to transmit torque. For delivering power, a longitudinal shaft can be used
by an automobile. Drive shafts that are short are used mainly for sending power
from transmission, differential and transaxle to wheels. Most vehicles come
with a gearbox and a clutch. A drive shaft that connects a rear differential to
the gearbox is known as a prop-shaft or a propeller shaft. Drive shafts come in
one-piece, two-piece and slip-in-tube drive.
