Abstract
Official abstract text for this publication.
The present invention relates to a toothed belt including: a back portion; a tension member embedded in the back portion in a belt longitudinal direction and including a twisted cord including a steel fiber; a plurality of belt teeth formed on an inner peripheral side of the back portion along the belt longitudinal direction; and a cover layer provided between the tension member and a belt tooth bottom formed between the belt teeth, in which the cover layer has a thickness in a range of 0.2 mm to 1.0 mm, and the back portion, the belt teeth, and the cover layer are integrally formed of a thermoplastic elastomer.
First claim
Opening claim text (preview).
What is claimed is: 1 . A toothed belt comprising: a back portion; a tension member embedded in the back portion in a belt longitudinal direction and comprising a twisted cord comprising a steel fiber; a plurality of belt teeth formed on an inner peripheral side of the back portion along the belt longitudinal direction; and a cover layer provided between the tension member and a belt tooth bottom formed between the belt teeth, the cover layer being exposed as part of the belt tooth bottom, wherein the toothed belt has a total belt thickness of 9 mm to 16 mm, and the cover layer has a thickness in a range of 0.3 mm to 0.6 mm, the back portion including a part disposed on a side of the tension member opposite to the plurality of belt teeth, and the back portion, the belt teeth, and the cover layer are integrally formed of a thermoplastic elastomer. 2 . The toothed belt according to claim 1 , wherein a pitch between the belt teeth is 14 mm or more, and a height of each of the belt teeth is 5 mm or more. 3 . The toothed belt according to claim 1 , wherein the plurality of belt teeth, when the toothed belt is wound around a plurality of toothed pulleys, each having a plurality of pulley teeth formed on an outer periphery thereof so as to mesh with the belt teeth, is configured such that a tip portion of each of the belt teeth comes into contact with a pulley tooth bottom formed between the pulley teeth, and a tip portion of each of the pulley teeth comes into contact with the belt tooth bottom. 4 . The toothed belt according to claim 3 , which is to be used in an environment in which a tension applied to the toothed belt fluctuates due to an external factor, and the tension is 0.30 kN/mm or more in a normal state and is 0.80 kN/mm to 1.10 kN/mm at most. 5 . A toothed belt power-transmission device comprising: the toothed belt according to claim 1 ; and a plurality of toothed pulleys each having a plurality of pulley teeth formed on an outer periphery thereof so as to mesh with the belt teeth of the toothed belt, wherein the toothed belt is wound around the plurality of toothed pulleys such that a tip portion of each of the belt teeth comes into contact with a pulley tooth bottom formed between the pulley teeth and a tip portion of each of the pulley teeth comes into contact with the belt tooth bottom, thereby performing synchronous power-transmission. 6 . The toothed belt power-transmission device according to claim 5 , wherein the toothed belt is used in an environment in which a tension applied to the toothed belt fluctuates due to an external factor, and the tension is 0.30 kN/mm or more in a normal state and is 0.80 kN/mm to 1.10 kN/mm at most.
