V belt for power transmission

A V belt for power transmission to be stretched over a driving pulley and a driven pulley to effect power transmission therebetween, said V belt comprising:

• a looped metallic belt;
• a plurality of V-shaped metallic blocks fitted on said metallic belt in a continuous manner along the length of said metallic belt, said V-shaped blocks each having at the upper part thereof a concave groove radially outwardly opening of said V belt so that said metallic belt faces thereon;
• and
• a plurality of stoppers each respectively adapted to be fitted onto one of said V-shaped blocks to secure the V-shaped block to said metallic belt;
• said V-shaped blocks include on the one hand a number of V-shaped blocks of a type each having, on front and rear faces thereof in the length direction of said V belt, concave places located radially inside of said metallic belt, respectively, and on the other hand a number of V-shaped blocks of a type each having, on either face thereof in the length direction of said V belt, a concave place located radially inside of said metallic belt and, on the other face thereof in the length direction of said V belt, a convex part located radially inside of said metallic belt;
• a plurality of rollers each respectively disposed between said concave place of said V-shaped blocks of said type at said other hand end and one of said concave places facing thereto of a corresponding one of said V-shaped blocks of said type at said one-hand end;
• and
• said convex part of each of said V-shaped blocks of said type at said other-hand end engages with one of said concave places facing thereto of a corresponding one of said V-shaped blocks of said type at said one-hand end.

• said V-shaped blocks include a number of V-shaped blocks of a first type each having, on front and rear faces thereof in the length direction of said V belt, concave places located radially inside of said metalic belt, respectively, and a number of V-shaped blocks of a second type each having, on either face thereof in the length direction of said V belt, a concave place located radially inside of said metallic belt and, on the other face thereof in the length direction of said V belt, a convex part located radially inside of said metallic belt;
• a plurality of rollers each respectively disposed between said concave place of said V-shaped blocks of said second type and one of said concave places facing thereto of a corresponding one of said V-shaped blocks of said first type;
• and
• said convex part of each of said V-shaped blocks of said second type engages with one of said concave places facing thereto of a corresponding one of said V-shaped blocks of said first type.

• a plurality of rollers each respectively disposed between one of said V-shaped blocks and another of said V-shaped blocks adjacent thereto at the radially inner side of the loop of said metallic belt;
• each V-shaped block has concave places formed to receive one of said rollers at the front and rear thereof in the length direction of said V belt, respectively;
• and
• said V belt includes at least two types of V-shaped blocks, a first type having a first predetermined dimension as the distance between the deepest parts of respective said concave places thereof and a second type having a second predetermined dimension as the distance between the deepest parts of respective said concave places thereof.
