摘要： A heavy-duty power transmission V-belt includes right and left tension members having concave parts on upper and lower faces thereof, and a large number of blocks having fitting parts for compressedly fitting the tension members therein on right and left side faces of the blocks. By compressedly fitting the tension members in the fitting parts of the blocks, the respective blocks are fixedly engaged with the tension members so as to allow the side faces thereof to be brought into contact with a groove face of the pulley. An innermost lower face is formed in an innermost portion of the fitting part of each block, and an innermost lower face angle &agr; between the innermost lower face and a vertical plane is determined so as to have a relationship of &bgr;−3

摘要： A heavy-duty power transmission V-belt is so designed that respective upward projections each having an arcuate cross section of respective blocks are fixedly engaged with respective bottom-surface grooves each having an arcuate cross section of a tension member. The radius of curvature R2 of each bottom-surface groove is set larger than the radius of curvature R1 of the upward projection of the block (R2>R1) in the state that the tension member is put strait. Thereby, when the V-belt bends around a pulley, it can be avoided that a large local strain occurs at the bottom-surface groove. This allows a firmly fixed state of each block by the tension member to be maintained for a long time.
