A belt is a looped strip of flexible material
used to mechanically link two or more
rotating shafts
They may be used as a source of motion, to
efficiently transmit power, or to track relative
movement. Belts are looped over pulleys.

Belt drives are cost-effective. ...
They are simple to use.
Belt drives do not require parallel shaft.
They have a low maintenance cost.
They come with overload and jam protection.
Different speeds can be obtained by means of
step or tapered pulleys.



The main disadvantage of belt drives is that
they are susceptible to contamination by dirt,
lubricants, oil, water, etc., which can cause
problems with operation.
Belt drive requires filter elements that help
reduce contaminants from entering the system
during operation.
The belt drive requires regular replacement
due to wear and tear on the pulleys and
bearings.

The flat belt is the simplest type, and made
from leather, fabric or rubber-coated fabric.
Flat belts are power transmission belts that are
flat and made of rubber, synthetic composites,
or leather. They are used to transfer rotational
power in industrial equipment and conveyor
systems. Flat belts have a low profile with a
positive grip, which makes them suitable for
high-speed drive applications.

A toothed belt; timing belt; cogged belt; cog
belt; or synchronous belt is a flexible belt with
teeth mounded onto its inner surface. Toothed
belts are usually designed to run over matching
toothed pulleys or sprockets.

A v-belt is a flexible and efficient power transmission
device capable of transferring power from one shaft to
another. It is known for its trapezoidal shape that
wedges securely into the sheaves of a shaft.
The V-shape causes the belt to wedge tightly into the
channel, increasing friction and allowing high torques
to be transmitted.
The belts have high-strength ropes.
The belt, made from natural fibers, synthetic strands,
or steel. are embedded in a firm rubber compound.

Chain drive is a way of transmitting
mechanical power from one place to another. It
is often used to convey power to the wheels of
a vehicle, particularly bicycles and motorcycles.
It is also used in a wide variety of machines
besides vehicles.

They can be used for both long and short
distances.
A number of shafts and be driven from a single
chain.
They are compact and have small overall
dimensions.
They do not present fire hazard.
Temperature and environmental conditions do
not affect their working.
They do not require initial tension.




The initial cost of production of the chains is
relatively higher.
The chain drive needs accurate mounting and
maintenance.
The chain drives sometimes have velocity
fluctuations.
Conventional chain drive suffers vibrations
due to chordal effect.

Flat top chain conveyors are ideally suited for
feeding and interlinking bottles, cans or small
boxes in the food, beverage, glass,
pharmaceutical and paint industries. Or with
steel chain for the transport of hot, sharp or
oily products.

A silent chain is essentially an assemblage of
gear racks, each with two teeth, pivotally
connected to form a closed chain. The links are
pin-connected, flat steel plates with straight
teeth. Silent chains are quieter than roller
chains, can operate at higher speeds, and can
transmit more load for the same width.

Leaf chain is a rollerless chain that is
commonly used on forklift trucks and in other
material handling applications. Leaf chain is
constructed of steel link plates mounted sideby-side on pins. The contour of the link is the
same figure-eight shape found on standard
roller chains. The chain can flex at each pin.
