Rubber V-belts have a v-shaped profile and hence the name. There are many variations of the v-belt. Most of the V-belts are either standard or inverted. A rubber V-belt is a continuous band for transferring power or conveying materials from one shaft or wheel to another and these belts have several benefits compared to the other drive systems. They provide an additional amount of stretch which is not the case with other belts. The belts are able to work smoothly and quietly, without the requirement of lubrication. This is an important feature of rubber V- belts.

Rubber V-belts are available in different sizes and types and are suitable for a wide range of applications. They have the capability of accommodating a wide range of horse power speeds and outputs which exist in the industrial drive systems.

Buying Tips Following are certain specifications of V-Belts: Tensile Strength: To withstand maximum load or stress without any damage and it is measured as the ratio of maximum load to the cross sectional area of the belt. Operating Speed: The maximum working speed of the rubber V-belt. Operating Temperature: The temperature range at which the belt is designed to operate properly without any damage. Material of Construction: This is to select the type of rubber required to produce the belts. Length: The cross sectional length of the top flat portion of the V-belt. Width: It is the overall width of the V-belt. The effective width should be considered while selecting the belt for a specific drive mechanism.

Types of rubber used in rubber V-belts

• Natural Rubber
• Neoprene
• Polyurethane
• Butyl Rubber (IIR)
• Ethylene Propylene Diene Monomer (EPM, EPDM)
• Chloroprene rubber
• Urethane

Types of V-Belts

• Raw Edged V-Belts: They are used when there is the chance of constant slippage of the other V-belts.
• Narrow V-Belts: They have a narrower pitch width when they are compared to the other types of V-belts.
• Ribbed V-Belts: These belts consist of two or more V-like formations which are placed next to one another and the cross sectional picture looks rather like a multiple W-Belt.
• Classic V-Belts: It is a single V shaped belt without any ribs or raw edges.
