What is the difference between a v-belt and a wedge belt?

V-belts & wedge belts both come under the term friction v-belts, meaning they need tension to maintain enough friction between the pulley and belt to transmit power.

When compared, the v-belt and wedge belt look similar. However, on closer inspection you’ll see there are differences. These slight variances may seem subtle, but nevertheless it is important to select the correct belt for your machine.

The v-belt was pioneered by John Gates of the Gates Rubber Company in 1917 and as its name suggests, a v-belt fits into a V-shaped pulley. The sides of the v-belt are tapered, fitting into the pulley perfectly to minimise slippage. There are many types available, including wrapped, raw edge cogged and banded v belts. Known for delivering a cost-effective method of power transmission. These belts are quiet in operation and are low maintenance. Making them one of the most popular belts on the market.

The wedge belt has a different profile which is, yes you've guessed it, wedge-shaped. These belts were created as a result of the demand for high power transmission with reduced space requirements. The wedge belts features improved cord construction and optimum cord placement when compared to the V-belt. This gives wedge belts the capacity to transmit more power. The wedge shape of these belts delivers a higher level of support than classical V belts, so fewer belts are required to transmit the load, resulting in  a reduced drive weight and size.
