摘要:
Toothed belt comprises teeth and bottoms which are alternately formed at one surface of the toothed rubber layer of the toothed belt. A fabric is provided at the outer surface of the teeth and the bottoms. A back rubber layer is integrally provided at the other surface of the toothed rubber layer. A plurality of cords are interposed at the interface between the toothed rubber layer and the back rubber layer. A large number of modified microfibers are intermixed throughout the toothed rubber layer. The modified microfibers consist of a copolymer of polyolefin and nylon fiber. The modified microfibers are oriented in the length direction of the toothed belt as a whole.

A toothed belt includes a toothed rubber layer having teeth formed on a surface thereof and containing a plurality of short fibers entirely distributed therein. The surface of the toothed rubber layer, on which the teeth are formed, is covered with a cover fabric. A back rubber layer is integrally applied to the other surface of the toothed rubber layer. A plurality of cord elements is disposed across a width of the belt and is intervened between the toothed rubber layer and the back layer in such a manner that a portion of each cord element is embedded in the toothed rubber layer, and the remaining portion thereof is embedded in the back rubber layer. The short fibers are entirely distributed in the toothed rubber layer and are regularly oriented.

A toothed belt includes a front rubber layer having teeth formed in the front rubber layer. A plurality of short fibers are entirely distributed in the front rubber layer. A first side of the front rubber layer is covered with a cover fabric. A back rubber layer contacts a second side of the front rubber layer. A plurality of cord elements extend along a length of the belt and are interposed between the front rubber layer and the back rubber layer in such a manner that a portion of each cord element is embedded in the front rubber layer, and the remaining portion of each cord element is embedded in the back rubber layer. Additionally, that portion of the plurality of short fibers that is positioned in a peripheral area of the front rubber layer adjacent to the upper surface of the front rubber layer is substantially parallel to an upper surface of each tooth of the front rubber layer, and another portion of the short fibers that is positioned in a central area of each tooth of the front rubber layer is substantially perpendicular to the lower surface of the front rubber layer.
摘要:
A stock rubber is provided with chopped aramid fibers and chopped polyester fibers blended in the rubber component, which is EPDM. The chopped polyester fibers are longer than the chopped aramid fibers. A transmission V-belt is obtained and molded from the stock rubber. When molding, the chopped aramid fibers and the chopped polyester fibers are oriented in a width direction of a belt body of the V-belt.
