The working principle of the multi-wedge belt wheel is a transmission process which is composed of a plurality of inclined planes and forms a number of hydrodynamic pressure wedges along its circumference when working. Multi-wedge belt, also known as multi-groove belt, is mainly used in engine, motor and other power equipment transmission.
