The original V-belt was developed in 1917 by the Gates Rubber Company. The name V-belt was decided upon due to the V-shaped cross-section of the belt.
V-belts are also commonly known as Vee belt are a rubber belt with cord members which can be produced in polyester or aramid, steel, Kevlar. The V-Belt has many sections (widths) and can transmit drives for all sorts of equipment such as pumps, building air conditioning, plant and agricultural machinery, grass machinery and lots more applications.
The V shape of the belt sits in a groove in the pulley which stops the V-belt slipping off and keeps it in-line. The V-belt will also tend to wedge into the groove of the pulley as the load increases – the greater the load, the greater the wedging action this improves torque transmission and makes the Vee Belt an effective solution for power transmission.
V-Belts can be purchased in various fixed lengths or in some cases in open length section; these can be joined to make a belt the required length. As well as the original classical wrapped V-Belt, other types such as Wrapped wedge, Cogged Raw Edge, Variable Speed and Banded V Belts are all available.
For high-power requirements, banded V-Belts are recommended – two or more V-Belts are joined by a backing/band that keeps them together when running and not allowing the V Belts to slip or elongate within the drive.
For Lawn & Garden Machinery V-Belts that are Kevlar corded and dry cotton wrapped are recommended.
