Problems solved by technology

This covering leads to forming problems in the forming process during the production of the ribbed V-belt, while the noise behavior is insufficient especially when wet and above all the bending flexibility is always insufficient at low temperatures
[0003] These numerous solutions for the coating of drive belts show that the development in this regard is not yet over

Embodiment Construction

[0057] The invention will now be explained by means of an exemplary embodiment with reference to the schematic drawings.

[0058] The only figure shows a drive belt 1, which is formed as a ribbed V-belt, with a cover layer 2 as the belt back, a reinforcing fabric layer and a substructure 4, the reinforcing fabric layer has a Tensile carriers 3 in the form of individual threads arranged running parallel in the longitudinal direction. The covering layer and the substructure constitute this elastic matrix based on vulcanized rubber, for example based on EPDM. The substructure has a multi-wedged triangular structure consisting of wedges 5 and grooves 6 . The substructure here includes the force transmission region 9 .

[0059] The cover 8 (here only covering the force transmission region 9 and the wedge portion 7 ) consists only of a single-layer LLDPE film. Here, the LLDPE film is applied to the substructure mixture before packaging.

[0060] The tensile carrier 3 is made, fo...

Abstract

The invention relates to an article with an elastic matrix based on vulcanized rubber. The article is in particular a drive belt (1) in the form of a ribbed V-belt having a cover layer (2) as the back of the belt and a substructure (4) with a force transmission zone (9) , wherein at least the force transmission area is provided with a covering (8), wherein the covering of the force transmission area in turn consists of at least one film, wherein the film contains at least 50% by weight of a linear polyethylene with a low density ( LLDPE) and wherein the film is produced such that the film melts during vulcanization and simultaneously forms a firm adhesive composite of the substrate and the covering.

Description

technical field [0001] The present invention relates to an article with an elastic matrix based on vulcanized rubber, with a wear-sensitive The surface of the article is provided with a covering. The elastic base is usually also provided with an embedded reinforcing fabric or stretch carrier which can be embodied as a single layer or as multiple layers. Background technique [0002] An item exposed to dynamic loads and thus to wear and noise generation, such as drive belts, conveyor belts or air spring bellows, wherein drive belts are of particular importance. The elastic base body of the drive belt here comprises a covering as the rear side of the belt and an understructure with the force transmission area. The drive belt, which is an intensive use area, is provided with a covering, in particular in the area of ​​this force transmission area, in order to reduce noise and increase wear resistance. Various covering types are known for this purpose. A lacquer covering bas...
