Abstract
Die invention relates to a drive belt, in particular V-belt, V-ribbed belt or toothed belt on an elastomer or polyurethane base, with belt backing and at least one tension member, comprising an optically detectable load and wear state display. According to the invention, a recess if formed over at least one belt section, and accommodated a flat support, wherein the support is furnished, in particular coated or impregnated with irreversibly thermochromic pigments, in such manner that a colour change or discolouration takes place at a predeterminable temperature load threshold.
Claims9
A drive belt, on elastomer or polyurethane base with belt backing, comprising an optically detectable load and wear state display,
- characterized in that
- a recess is formed in the belt over at least one belt section, and accommodates a flat, flexible support which is furnished with irreversible thermochromic pigments or a thermochromic layer, in such manner that a colour change or discolouration takes place at a predeterminable temperature load threshold of the belt,
- wherein the recess is formed on the back of the belt over at least one belt section, and accommodates a textile structure or film as the support, wherein the textile structure or film is furnished, with irreversible thermochromic pigments in such manner that a colour change or discolouration takes place at the predeterminable temperature load threshold,
- wherein the recess is formed over the entire course of the belt backing, and the textile structure or film is present as a band or strand.
A drive belt, on elastomer or polyurethane base with belt backing, comprising an optically detectable load and wear state display,
- characterized in that
- a recess is formed in the belt over at least one belt section, and accommodates a flat, flexible support which is furnished with irreversible thermochromic pigments or a thermochromic layer, in such manner that a colour change or discolouration takes place at a predeterminable temperature load threshold of the belt,
- wherein
- the support, the textile structure or the film contains multiple layers or sections with thermochromic pigments, each of which undergo a colour change at different temperatures, so that different load states can be represented in the manner of a traffic light function.
A drive belt, on elastomer or polyurethane base with belt backing, comprising an optically detectable load and wear state display,
- characterized in that
- a recess is formed in the belt over at least one belt section, and accommodates a flat, flexible support which is furnished with irreversible thermochromic pigments or a thermochromic layer, in such manner that a colour change or discolouration takes place at a predeterminable temperature load threshold of the belt,
- wherein
- the support with its irreversible thermochromic pigments is provided as a prefabricated product.
A structure, consisting of a support material on a nonwoven, knitted, woven or crocheted or film base, wherein the support material is furnished with at least one coating or print containing irreversible thermochromic pigments or consisting of such pigments, further with an underside configured for a materially bonded connection and an optically transparent protective layer,
- wherein
- the underside has an adhesive coating
- and a separating layer is provided between the adhesive coating and the support material.
