Embodiment Construction

[0030] figure 1 A belt 16 is shown as traction element for elevator technology, in particular in the form of a flat belt. Material A is preferably polyurethane and forms the belt core 18 . The coating 19 consists of material B, which is preferably a mechanically high-stress PU varnish. In this case, the tension carrier 17 is embedded in the belt core 18 while being completely sheathed by the first material A. As shown in FIG. The tensile carrier 17 is preferably a tensile carrier made of steel. In a particularly preferred embodiment, the coating 19 completely surrounds the belt core 18 .

Abstract

The invention relates to a belt (16) for drive systems, said belt at least consisting of: an elastic and flame-retardant belt body (A) made from a polymeric material (18) and at least one flame retardant additive, said belt body comprising a cover layer as a belt back and a substructure which has a force transmission zone; and a tension member (17) which is embedded in the belt body, wherein the belt body (A) is partially or completely provided with a coating (19), which coating is single- or multi-layered.

Description

technical field [0001] The invention relates to a belt for drive technology, consisting at least of the following components: [0002] a belt body made of at least one polymer material having elastic and flame-retardant properties, including a cover layer as the back of the belt and an understructure with a force transmission zone; and [0003] Tension carrier embedded in the belt body. Background technique [0004] Such belts, which are also called drive belts or power transmission belts, can be designed as flat belts, wedge-shaped belts, wedge-shaped grooved belts, toothed belts or as connecting cables. [0005] The elasticity of the belt is achieved in that the belt body and thus also the covering layer and the substructure consist of an elastic polymer material, wherein two groups of materials, elastomers and thermoplastic elastomers, should be mentioned here in particular. Of particular interest are elastomers based on vulcanized rubber mixtures, which comprise at lea...
