2. Chain drive
• 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
• 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
• The chains are made up of a number of rigid links that are hinged
together by pin joints to provide the flexibility needed to wrap
driving and driven wheels.

4. Application Of Chain Drive
• They are used for power transmission
• They are used in transportation industry
• They are used in wood working machinery
• They are used in agricultural machinery
• They are used in oil well drilling rigs
• They are used in building construction
• They are used in material handling equipment
• They are used for lifting load
• They are used for carrying materials
6. Advantages Of Chain Drive
• 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
• They have very high efficiency (up to 96%)
• They do not slip
• They are easier to install
• They can withstand abrasive conditions
• They can operate in wet conditions
7. Disadvantages of Chain drive
• They cannot be used where slip is the system requirement
• They require precise alignment compared to belt drives
• They require frequent lubrication
• They have less load capacity compared with gear drives
• Their operation is noisy and can cause vibrations
• They are not suitable for non-parallel shafts
• They can not be used where precise motion is required
• They require housing
• They require adjustments for slack like tensioning device
