Title
(DE) REIBUNGSANTRIEBSRIEMEN UND VERFAHREN ZU DESSEN HERSTELLUNG
(EN) FRICTION TRANSMISSION BELT AND METHOD FOR PRODUCING SAME
(FR) COURROIE DE TRANSMISSION À FRICTION ET PROCÉDÉ DE PRODUCTION DE CELLE-CI
Abstract
(EN)
A friction transmission belt (B) includes a belt body (10) made of a rubber composition and wrapped around pulleys to transmit power. A thermoplastic resin film(s) (16) adheres to a pulley contact-side surface of the belt body (10), and friction coefficient reduction powder particles (17) dispersively adhere to the pulley contact-side surface of the belt body (10).

(FR)
La courroie de transmission à friction (B) selon l'invention comporte un corps (10) de courroie constitué d'une composition de caoutchouc et s'enroulant autour d'une poulie pour transmettre la puissance. Une pellicule (16) de résine thermoplastique est fixée à une surface latérale de contact avec la poulie sur le corps (10) de courroie et une poudre (17) abaissant le coefficient de frottement est dispersée et fixée à celui-ci.
