The cross-section of a double v belt is a hexagon formed by two congruent trapezoids. The central axis containing the tension wire is located exactly in the middle of the belt. The tension line located at the center of the belt gives the hexagonal belt good flexibility and lower stretchability. Has typical bending transmission performance. The unique performance is attributed to its special construction and unique top surface treatment. This type of band is particularly suitable for bending situations in different directions on the same plane. Mainly used in the fields of agricultural machinery and mechanical engineering.
