Conveyor History: V Belts

V belts are some of the most widely used style of belt used in manufacturing today. Surprisingly enough, V belts have been around for nearly 100 years. Over the years, inventors have perfected the design, but they still use the same basic principles discovered so long ago.

The V belt was invented by John Gates from the Gates Rubber Company in 1917. This company is actually still in operation today, and sells many variations on their original belt system. John Gate’s original invention was for a trapezoidal endless belt. The new feature of the belt used a “V’ shaped rotary motor that traps the belt at an angle. This prevents the belt from slipping off of the rotary system, enabling the belt to continue operating without difficulty. This system also offers the advantage of providing extra protection when heavy loads are placed onto the conveyor belt. Heavier loads apply more pressure on the rotary system, which helps tighten the connection between the belt and rotor. This is an additional safety measure that is ideal for protecting the conveyor system, nearby workers, and the materials on the belt.

Over the years, a few changes and adjustments were added to the original belting system idea. One change was to use multiple V belting systems together for high-power requirements. The belts are linked together and provides additional rotating strength and power. Another variation on the V belt uses metal fibers to strengthen the rubber belt. Some belts use metal chains linked together rather than the traditional rubber belting system. These variations, however, are not as powerful as the original V belt design.

Many factories all over the world now use the V belt system for a variety of conveyor belting tasks during day-to-day factory operations. Even some engines and smaller rotating machines use a V belt design to prevent the motor belts from slipping during use.
