Claims

[Claims for Utility Model Registration] (1) A belt having at least one V-belt main body formed by laminating a compression part, a tensile member, and a tension part from below, the lower surface of which is formed into a circular arc. A power transmission belt characterized in that protrusions and grooves extending in the longitudinal direction of the belt are alternately formed with surfaces. (2) The lower surface of the compression part is provided with convex stripes having an arcuate surface on both sides thereof, and a concave stripe having an arcuate surface is arranged between the pair of protrusions, Claim 1 of the Utility Model Registration Claim. The power transmission belt described. (3) The pair of protrusions is 0.08 to 0.08 of the bottom width of the compression part.
A utility model registration request that has a circular arc surface drawn with a radius of 0.7 times, and the concave strip located between the convex strips has an arc surface that is in contact with the circular arc surface of the convex strip. The power transmission belt according to the range 1 or 2. (4) The power transmission according to claim 2 or 3 of the utility model registration claim, wherein the depth of the groove having an arcuate surface located at the center is set to 1/2 or less of the height of the compression part. belt. (5) The pair of protrusions is 0.08 to 0.08 of the bottom width of the compression part.
It has a circular arc surface drawn with a radius of 0.25 times, and the circular arc surface of the concave strip located between the convex strips is connected to the circular arc surface of the convex strip through a tangent part of a predetermined length. Paragraph 1 or 2 of consecutive claims for utility model registration
Power transmission belt as described in section. (6) The power transmission according to claim 5 of the utility model registration claim, wherein the depth of the groove having an arcuate surface located at the center is set in the range of 1/10 to 1/2 of the height of the compression part. belt. (7) The convex and concave lines having arcuate surfaces formed on the compressed lower surface are adhered and covered with a continuous rubberized lower canvas according to claims 1 to 6 of the Utility Model Registration Claims.
