Abstract
Official abstract text for this publication.
The present invention relates to a V-ribbed belt to be wound around plural pulleys and used, including an extension layer that forms a back surface of the V-ribbed belt, a compression layer provided on one surface of the extension layer and having plural ribs extending parallel to each other along a longitudinal direction of the V-ribbed belt, and a load carrying cord embedded between the extension layer and the compression layer along the longitudinal direction of the V-ribbed belt, in which a distance from an outer peripheral portion of the load carrying cord on the rib side to a tip portion of the rib is from 2.0 to 2.6 mm, and a distance from the outer peripheral portion of the load carrying cord on the rib side to a bottom portion of the rib is from 0.3 to 1.2 mm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A V-ribbed belt having an inside and an outside, the V-ribbed belt comprising: an extension layer that forms a back surface of the V-ribbed belt, a compression layer provided on one surface of the extension layer and having plural ribs extending parallel to each other along a longitudinal direction of the V-ribbed belt, and a load carrying cord embedded between the extension layer and the compression layer along the longitudinal direction of the V-ribbed belt, the load cord having an outer peripheral portion with a rib side and an opposite side spaced from each other in a direction between the inside and outside of the V-ribbed belt, wherein a distance from the outer peripheral portion of the load carrying cord on the rib side to a tip portion of the rib is from 2.0 to 2.6 mm, and a distance from the outer peripheral portion of the load carrying cord on the rib side to a bottom portion of the rib is from 0.3 to 1.2 mm. 2. The V-ribbed belt according to claim 1 , wherein a width of the rib is from 2.0 to 3.0 mm and a distance from the bottom portion of the rib to the tip portion of the rib is from 1.1 to 1.8 mm. 3. The V-ribbed belt according to claim 1 , wherein a distance from a center of the load carrying cord to the back surface of the V-ribbed belt is from 0.6 to 1.5 mm. 4. The V-ribbed belt according to claim 1 , wherein a diameter of the load carrying cord is from 0.6 to 1.25 mm. 5. The V-ribbed belt according to claim 1 , wherein an edge of the tip potion of the rib is a sharp corner shape. 6. The V-ribbed belt according to claim 1 , wherein the extension layer is formed of a rubber composition.
