Abstract
Official abstract text for this publication.
A V-ribbed belt having an elastic main body constructed from at least one rubber mixture including an outer ply as a belt backing and a substructure having a ribbed force-transmitting side. To improve friction and optimize service life the V-ribbed belt has a coating made of a knitted fabric on its force-transmitting side, in which the average basis weight of the textile before vulcanization is between 140 and 190 g/m2.
First claim
Opening claim text (preview).
1 . A V-ribbed belt having an elastic main body constructed from at least one rubber mixture comprising an outer ply as a belt backing and a substructure having a ribbed force-transmitting side, wherein the ribbed force-transmitting side has a textile overlay including a knitted fabric, wherein the average basis weight of the textile before vulcanization is 140 g/m 2 to 190 g/m 2 , and wherein the basis weight of the textile was determined according to DIN EN 12127, version 1997-12. 2 . The V-ribbed belt according to claim 1 , wherein the average basis weight of the textile before vulcanization is 145 g/m 2 to 170 g/m 2 . 3 . The V-ribbed belt according to claim 1 , wherein the knitted fabric is composed of a combination of a multifilament yarn made of polyamide and an elastic thread. 4 . The V-ribbed belt according to claim 3 , wherein the polyamide is PA 6 or PA 6.6. 5 . The V-ribbed belt according to claim 3 , wherein the elastic thread is composed of polyurethane. 6 . The V-ribbed belt according to claim 1 , wherein ethylene-propylene rubber (EPM) or ethylene-propylene-diene rubber (EPDM) or a combination of EPM and EPDM is employed as the rubber for the rubber mixture of the substructure. 7 . The V-ribbed belt according to claim 1 , wherein the rib depth is between 2.2 and 2.6 mm. 8 . The V-ribbed belt according to claim 1 , wherein the textile overlay is an open-pored knitted fabric. 9 . The V-ribbed belt according to claim 8 , wherein the knitted fabric is a single jersey. 10 . The V-ribbed belt according to claim 1 , wherein the textile overlay is knitted in a plated manner. 11 . The V-ribbed belt according to claim 1 , wherein: the knitted fabric is composed of a combination of a multifilament yarn made of polyamide and an elastic thread, the polyamide is PA 6 or PA 6.6, the elastic thread is composed of polyurethane and has an elongation at break according to DIN EN ISO 2062:1995 of more than 100%, and the rib depth is between 2.2 and 2.6 mm.
