Definition Drive belt can be define as a machine component that

transmit power beetween other component

It is a closed strip of material that links pulleys and other

parts of the machine.

Flat BeltFlat belts were used early in line shafting to transmit

power in factories. They were also used in countless

farming, mining, and logging applications, such as

bucksaws, sawmills, threshers, silo blowers,

conveyors for filling corn cribs or haylofts, balers,

water pumps (for wells, mines, or swampy farmfields), and electrical generators. The flat belt is a

simple system of power transmission that was well

suited for its day. It delivered high power for high

speeds (500 hp for 10,000 ft/min), in cases of widebelts and large pulleys. These drives are bulky,

requiring high tension leading to high loads, so vee

belts have mainly replaced the flat-belts except when

high speed is needed over power.

Flat BeltBelt composed than the average coil material used to deliver

the proposal between the two pulley block. Flat belt may bemade of various materials such

aslatex canvas, plastic, or flexible metal.

BeltsMulti-Speed Gates Multi-Speed (Variable Speed) Belts

Multi-Speedbelts have a distinct shape. Multi-Speed belttop widths are usually greater than their thickness. This

permits a greater range of speed ratios than standard belts.

usually cogged or notched on the underside, Multi-Speed

belts are specified for equipment which require changes

in driveNspeed during operation. Multi-Speed belts are specified by Top Width,Outside

Circumference, and the required Groove Angle. The groove

angle can be measured from the drive pulleys.

V-Belt :

Trapezoid shaped belt, weave and consist of fibersembedded in resin and then wrapped with webbingand sap are used to transmit power from one tothe shaft to the other through the pulley rotateswith the same or differing speeds.

ADVANTAGE V-BELT V-belt is more compact

Slip small compared to the flat belt

Quieter operation

Able to reduce the shock at start

Contained in the second round of the axis direction and a

second position of the shaft can be any

DISADVANTAGE V-BELT Can not be used for long distance axis.

Shorter life time

Construction is more complex than

the pulley for flat belt pulley
