Flat Belt Drive - Types, Advantage and Disadvantage
Types of flat belt driveFlat belts are the simple system for power transmission. It can deliver high power to moderate distance (up to 15m).
Flat belt drives further classified into
Open belt drive
Cross belt driveTiming Belt.

🔗Advantages and Disadvantages of Pulley used in power transmission (Pulley Drive)
Fast and loose pulley drive
It is used to stop the machine while driver continues to run; this can accomplish by shifting the belt to a loose pulley, which is freely run over the shaft.
Advantage of the flat belt drive
- The flat belts are very simple in design and cheaper.
- Smooth running and quiet running.
- Flat belts can be used for long distances, even up to 15 m.
- Precise alignments of shafts and pulleys are not as critical with flat belts.
- The periodic adjustment of the belt tension and belt replacement, when it is worn out, is easier in the case of flat belts.
- Flat belts are and very flexible and, therefore, they have the ability to bend and twist on pulleys and follow very tortuous paths.
- Flexible and longer belts can absorb shock and torsional vibration. Therefore, they are quieter and have better protection of machine against knocks or overloading.
- Fast and loose clutch action and variable output speed by cone pulley drive are possible with flat belt drives.
- They are durable.
Disadvantage of the flat belt drive
- High chance of slip off.
- Compared to v-belts, flat belts require significantly greater of pretension to transmit a certain torque without slip.
- Flat belts are not advisable for high outputs at high speeds. The flat belt cannot transmit high power as timing belt does.
- They are bulky, for a given transmission, flat belt drive requires a wide pulley.
