There are multiple types of gears used for multiple
purposes. There are many kinds of gears and shafts available in the market
according to sizes, materials, and shafts. The popular method of classifying
types of gears is based on the arrangement of shafts and axle. There are three
types of gears and shafts
arrangement, namely parallel shafts, intersecting shafts, and non-parallel or
non-intersecting axis. Gears are cylindrical wheels with teeth to transfer
energy from one place to another for operating a machine.
When there are two or more gears working together, the
transfer of power takes place when the energy moves from one shaft or axle to
the other. The parallel shafts and gears are called interlock gears. These are also
called simple gears or helical gears. This gears support transfer of energy in
rotational motion and can carry heavy loads without much noise. The manufacture
of parallel shaft gears is more expensive and these types of gears and shafts are used in
manual machines like clocks, car-steering, etc.
Intersecting gears function by perpendicular motion and
carry out energy transfer in a smoother way. The axes of shafts work
perpendicular to each other. These gears and shafts are less expensive and can be used in hand drills, locomotives,
marine equipment, etc.
The non intersecting gears work for power transfer in a
limited area. These are very inexpensive and production cost is very low. These
gears cannot bear much load. The example of non parallel or non intersecting
gears is hypoid gear or non-helical gear. These gears are used in rear wheels
of heavy vehicles, lifts, electrical mixers, and sprinklers.
