Abstract
Official abstract text for this publication.
The present invention relates to a toothed belt containing tooth parts that are disposed at predetermined intervals along a belt longitudinal direction, a cord, and a back side that has the cord embedded therein, in which the cord contains a Lang-twisted glass fiber, an adhesion treatment layer, and an overcoat treatment layer, the overcoat treatment layer is formed on a surface of the adhesion treatment layer, the back side is composed of a rubber composition, and the rubber composition contains from 5 parts by mass to 20 parts by mass of a plasticizer based on 100 parts by mass of a rubber component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A toothed belt comprising tooth parts that are disposed at predetermined intervals along a belt longitudinal direction, a cord, and a back side that has the cord embedded therein, wherein the cord comprises a Lang-twisted glass fiber, an adhesion treatment layer, and an overcoat treatment layer, and the overcoat treatment layer is formed on a surface of the adhesion treatment layer, and the back side is composed of a rubber composition, and the rubber composition comprises from 5 parts by mass to 20 parts by mass of a plasticizer based on 100 parts by mass of a rubber components, wherein the plasticizer comprises at least one selected from the group consisting of ether-based, ester-based, ether ester-based, phthalic acid-based, and adipic acid-based ones. 2. The toothed belt according to claim 1 , wherein the rubber composition constituting the back side has a rubber hardness rating, measured at 25° C., in a range of 70° to 85°. 3. The toothed belt according to any one of claim 1 , wherein the rubber composition constituting the back side has a rubber hardness rating, at −30° C., in a range of +0° to +4° relative to the rubber hardness rating measured at 25° C. 4. The toothed belt according to any one of claim 1 , wherein a starting torque of the toothed belt at −30° C. is less than 30 cN·m. 5. The toothed belt according to any one of claims 1 , wherein the rubber composition constituting the back side comprises at least chloroprene rubber. 6. The toothed belt according to any one of claims 1 , wherein the tooth parts are composed of a rubber composition and the rubber composition comprises at least chloroprene rubber. 7. The toothed belt according to any one of claims 1 , wherein the glass fiber is alkali-free glass.
