This paper introduced the characteristics of flat and V-shaped belt which were driven through the frictional force determined by the aspect of tribology for mechanical designs. Basic properties of the frictional belts were shown, at first, to design the transmitting belt systems, and then classical theory describing the critical state of frictional forces and tensions of the belt was also explained for mechanical designs, while practical theory was also introduced to determine the actual properties of the belt in driven state. Some principal benefits of CVT (Continuously Variable Transmission) driven by frictional belt were also shown introducing the behavior of the belt due to the tilting of the pulley on the sliding shaft, as an example of determined features of the frictional V-belt type CVT.
