PAES 302:2000 Engineering Materials – Flat Belts and Pulleys for Agricultural Machines Specifications and Applications

flat belt

belts used to transmit rotary motion and power between two shafts, which lie flat on the face of its corresponding pulley

flat belt pulley

wheel having flat or crowned face used to transmit motion and power by means of flat belts

flat belt drive

power transmission device used to transmit power and motion between two shafts consisting of flat belts which ride in flat pulleys

pulley diameter

outside diameter of the pulley

belt length

stretched-out length of the belt

speed ratio

ratio of the angular velocities of the pulleys making no allowance for slip and creep

belt speed

the linear speed of the belt calculated by multiplying the rpm and the diameter of the driver pulley and to the value of pi

Nomenclature

Dimensions of flat belts are designated by its width (W), and by its thickness (t).

Nylon cord belts

are endless belts made with single ply high tensile cords. They are oil and heat resistant. Their thin dimension allows them to be in smaller pulleys and with high-speed drives.

Rubberized fabric

Rubber belting is made from fabric or cord, impregnated and bound together by vulcanized rubber compounds. Advantages are high tensile strength, strength to hold metal fasteners satisfactorily and resistance to deterioration by moisture. Rubber belts are used in places exposed to the weather or the action of steams.
