2. Introduction
• 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.

3. Working…
• Most often, the power is conveyed by a roller chain, known as
the drive chain or transmission chain, passing over
a sprocket gear, with the teeth of the gear meshing with the
holes in the links of the chain. The gear is turned, and this
pulls the chain putting mechanical force into the system.

4. • Chain drives are well suited for this task
because the sprocket teeth and chain setup
results in a positive speed ratio and the ability
to transfer a large amount of torque within a
compact space.

• Chain drives are used in many types of industries to move,
slide, carry, push and pull a variety of materials. These drives
can be used to move objects directly by attaching pockets,
buckets, or frames to the chains. They can also be used
indirectly, such as turning rollers.
• Chain drives can also be used to synchronize or time
movements. For example, industrial combustion engines use
chain drives to control valve timing.

6. Advantages
• Do not slip or creep, and so are more efficient than belt drives.
• Are more compact than belt drives.
• Operate effectively at high temperatures.
• Are often easier to install than belt drives.
• Do not deteriorate due to oil, grease, sunlight, or age.
• Can withstand abrasive conditions.
• Can operate in wet conditions.
• Can be used on reversing drives.

7. Disadvantages
• Cannot be used in applications where the drive must slip.
• Require more precise alignment than belt drives.
• Typically require frequent lubrication.
• Are noisy and can cause vibrations.
• Do not have the load capacity or service life of gear
drives .
