摘要:
The invention is directed to a drive belt of rubber or rubber-like plastic having a surface protection (5) which includes polyamide-containing textile reinforcement and/or polyester-containing textile reinforcement. On the outer side, a surface coating (6) of a friction-reducing material in a matrix of at least one elastic addition polymer is provided. For improved heat resistance with good protection against wear, the elastic addition polymer has less than 2% by weight based on the polymer of structural components —O—CxRy—O— with x=1-3 and y=0-6. The R in a structural component can be the same or can be different and is selected from hydrogen and/or carbon-containing groups.

A power transmission belt (20) having an elastic main body (17) includes a top layer as the belt backing and a bottom section having a power transmission zone. The power transmission zone and/or the top layer has/have a coating (15, 16), characterized in that the coating (15, 16) of the power transmission zone and/or the top layer includes at least the following layer construction: a base coating (18) made of a textile material, wherein the base coating (18) forms a bond with the elastic main body (17) and has a surface coating (19) including at least a mixture A, which contains at least one reactive diluent as per DIN 55945:2007-03. The invention further relates to a method for producing such a power transmission belt. The novel coating concept is applicable in particular in a toothed belt.

摘要:
A flexurally elastic drive belt (1) has a cover layer (2), a reinforcement layer (3) formed of individual cords (4) and a substructure (5). The substructure can include ribs (6) and grooves (7). The drive belt is further provided with a textile overlay on the working side (8) thereof that is susceptible to wear. The textile overlay (10; section B of FIG. 1) of the drive belt (1) combines a very durable resistance to wear and a noise attenuation especially for wet noises. This is achieved in that the overlay has, in a state in advance of fabrication and vulcanization, an elongation at tear of at least 30% in the longitudinal direction and of at least 100% in the transverse direction and is made of a textile material including staple fibers in a proportion in terms of quantity of at least 30% by weight.
摘要:
V-ribbed belts are formed by thermoplastic shaping and contain ribs that run at least on a first side in a longitudinal direction of the V-ribbed belt. The first side contains a layer composed of a textile warp-knit fabric made up of two different yarns. The warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5N/1000 dtex, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, both based on 5% extension. The first and second yarns form a coherent network and the yarns do not twine around one another. V-ribbed belts can be formed using an elastic warp-knit fabric, whose extension is based on the construction of the knitted fabrics. The belts maintain better noise reduction both in the new state and after a relatively long service life.

The invention relates to V-ribbed belts (1) which have ribs (5) which run at least on a first side in the longitudinal direction of the V-ribbed belt and which are formed by thermoplastic shaping, and the first side has a layer composed of a textile warp-knit fabric (7) composed of two different yarns. In order to provide better noise reduction, the warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5 N/1000 dtex, based on 5% extension, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, based on 5% extension, wherein the first and the second yarn in each case form a coherent network, and the yarns are not twined around one another. V-ribbed belts can be formed effectively with an elastic warp-knit fabric of said type, whose extension is based not only on the construction of the knitted fabrics. It is surprising that the belts maintain the good noise properties both in the new state and also after a relatively long service life.
摘要:
The invention relates to an article including an elastic main body on the basis of a vulcanized rubber (17) having an article surface that is susceptible to wear, which is provided with a textile layer. The textile layer, particularly a woven fabric (16) or knitted fabric, has a mesh design that allows the vulcanized rubber (17) to penetrate to the textile surface to form a textile-vulcanized rubber hybrid system (15), wherein the vulcanized rubber portion on the textile surface can be controlled by means of the stitch number, stitch width and the thread design of the textile layer. The article is in particular a drive belt and in connection with the primary intended use, a method for making a drive belt is provided.
