V-Belt: What Is It? How Does It Work? Types Of, Uses
Wedge V-belt: Wedge belts are a type of v-belts that are primarily used for high power transmission with reduced space requirements. They can operate at 1.5 to 2 times the load of classical v-belts with the same top width. Because of the higher power rating, fewer wedge belts are needed to transmit the load.

When do synchronous belts need flanged pulleys?
When the span (center distance between shafts) is eight times or more the diameter of the smaller pulley, both pulleys should have flanges. Most synchronous belt drive systems should include at least one flanged pulley. Image credit: Gates Mectrol Inc.
