GEARS
Gear is a mechanical instrument having toothed
section generally used for transferring torque, force from one part of machine
to another part of machine.
BACKLASH
It is a minimum distance between the two mating
teeth in motion when the gear is driving the pinion.
Sometime it is also called as LASH or PLAY.
"In a pair of gears backlash is the amount
of clearance between mated gear teeth".
Theoretically, the backlash should be zero, but
in actual practice some backlash must be allowed to prevent JAMMING.
The other reason for backlash is allowing for
lubrication, manufacturing errors, deflection under load and expansion.
TYPES OF GEAR
Harmonic Drive :- This type of gearing system is used in motion control robotics and
aerospace, because it has advantage of lack of backlash, compactness and gear
ratio.
Spur Gears:-Spur gears are by far the most common type of gear and with the
exceptions of the "cog" the type of gear that has been around the
longest.Spur gears have teeth that run perpendicular to the face of the gear.
Helical Gears:- Helical gears are very similar to spur gears except the teeth are not
perpendicular to the face. The teeth are at an angle to the face giving helical
gears more tooth contact in the same area.
Helical gears can also be used on non-parallel
shafts to transmit motion.
Helical gears tend to run quieter and smoother
than spur gears due to the increased number of teeth in constant contact at any
one period of time.
Herringbone Gears:-Herringbone gears resemble two helical gears that have been placed side by
side. They are often referred to as "double helicals".
One benefit of herringbone gears is that it helps
to avoid issues related to side thrust created with the use of helical gears.
Bevel / Miter Gears:-Bevel gears are used mostly in situations that require power to be
transmitted at right angles (or applications that are not parallel). Bevel
gears can have different angles of application but tend to be 90°.
Worm Gears:-Worm gears are used to transmit power at 90° and where high reductions
are required. The worm resembles a thread that rides in concaved or helical
teeth.
Internal Gears:-Internal gears typically resemble inverted spur gears but are occasionally
cut as helical gears.
Racks & pinion:-A rack is basically a straight gear used to transmit power and motion in
a linear movement.
Face Gears:-Face gears transmit power at (usually) right angles in a circular motion.
Face gears are not very common in industrial application.
Sprocket :-Sprockets are used to run
chains or belts. They are typically used in conveyor systems.
