Drive Belt

Drive Belt


the flexible element of a belt drive. Since belts largely determine the operating capacity and durability of belt drives, they should have high traction and fatigue strength, sufficient flexibility, and as high a coefficient of friction as possible. Depending on the shape of their cross sections, belts are classified as flat belts, V-belts, multiple V-belts, and round belts.

Flat belts may be leather, rubberized, or fabric (cotton or wool). Leather belts are made from strips of high-quality hide that are glued or sewn together. Rubberized belts consist of several layers of a strong fabric, such as belting, held together by vulcanized rubber; these are the belts most often used in belt drives. Fabric belts are made of several layers of strong cotton or wool yarn. V-belts use several layers of cord fabric or strings in a rubber filler. The outer surface of the belts is wrapped with several layers of rubberized fabric. Cog belts are V-belts that have transverse teeth on the underside to increase flexibility. Multiple V-belts have a flat outer surface and lengthwise V-shaped protrusions on the underside; they are reinforced with braided cord.

Round belts are made either of cotton or leather and usually have a small diameter (4–8 mm). The use of polymer belts made from polyamide resins is promising; the belts can transmit high powers (hundreds of kilowatts) at high speeds (up to 100 m/sec).

Users, Specifiers and OEM's today, should speak directly to the belt manufacturer well before proceeding to design, upgrade, or indeed re-design an existing motor unit, machine, or operational plant build, as the technology, performance and material variants available to a belt manufacturer, are not only extremely diverse, but constantly improving, especially in cases where in the case of Optibelt for example, as part of its global services portfolio, will often design, test and produce an optimised drive belt, tailored to that user's / OEM's exact application.
