This document is a seminar presentation on belt drives submitted by Vignesh G. It provides a brief introduction stating that belt drives are commonly used to transmit power in applications like rice mills and sewing machines. It then lists the key factors that determine the amount of power a belt can transmit, including the belt's velocity, tension, arc of contact, and operating conditions. Finally, it distinguishes between open belt drives used to connect parallel shafts rotating in the same direction and crossed belt drives used to connect parallel shafts rotating in opposite directions.

3. ⦁ Gear Train
◦ Ex: Automobile, engines etc.
⦁ Chain Drive
◦ Ex : Bi-cycle , Motor cycle etc.
⦁ Belt Drive
◦ Ex: Rice mills, sewing machine etc.
⦁ Rope Drive
◦ Ex: lift, crane etc.

4. ⦁ Amount of Power Transmitted by belt
Depends on
◦ The velocity of the belt
◦ The Tension of the belt
◦ The arc of contact between the belt and smaller
pulley
◦ The condition under which the belt is used

6. ⦁ Open Belt Drive: The open belt drive is used
with shafts arranged parallel and rotating in
the same direction

7. ⦁ Crossed Belt Drive: The crossed belt drive is
used with shafts arranged parallel and
rotating in the opposite direction
