Abstract

Official abstract text for this publication.

A power transmission belt has an uneven surface of rubber which when the power transmission belt is wound around a flat pulley, comes in contact with the flat pulley. The uneven surface has projected parts each having a flat top surface.

First claim

Opening claim text (preview).

What is claimed is: 1 . A power transmission belt having an uneven surface of rubber which when the power transmission belt is wound around a flat pulley, comes in contact with the flat pulley, wherein the uneven surface has projected parts each having a flat top surface. 2 . The power transmission belt of claim 1 , wherein a total area of the flat top surfaces of the projected parts is 10 to 60% of an area of the uneven surface. 3 . The power transmission belt of claim 1 , wherein an outer diameter of each of the projected parts of the uneven surface in plan view is 0.3 to 1.4 mm. 4 . The power transmission belt of claim 1 , wherein a surface roughness (Rz) of the uneven surface is 0.05 to 0.25 mm. 5 . The power transmission belt of claim 1 , wherein the power transmission belt is a V-ribbed belt or a flat belt. 6 . The power transmission belt of claim 1 , wherein the uneven surface is a back surface of the power transmission belt. 7 . A belt transmission system in which the power transmission belt of claim 1 is wound around a plurality of pulleys, wherein the plurality of pulleys include a flat pulley with which the uneven surface of the power transmission belt comes in contact. 8 . A method of manufacturing a power transmission belt having an uneven surface of rubber which when the power transmission belt is wound around a flat pulley, comes in contact with the flat pulley, wherein a rubber composition is pressed against a molding surface that is a transfer surface of an uneven surface where each of projected parts has a flat top surface, thereby forming the uneven surface that comes in contact with the flat pulley.
