Abstract

Transmisión rotativa con anillo cónico de fricción (1, 2; 40; 80; 90; 101; 201) con un anillo de fricción (7; 54; 71; 83; 93; 107; 205; 304; 305) como un elemento de acoplamiento y con dos conos (4, 5; 51,55; 81,82; 91,92; 104, 105; 203, 204; 301,302, 303) como al menos dos elementos de transmisión rotativos, que pueden transmitir un par por fricción, estando prevista al menos durante el funcionamiento, una rendija llenada con un fluido (6; 106; 206; 306, 307) entre los conos (4, 5; 51, 55; 81,82; 91, 92; 104, 105; 203, 204; 301, 302, 303) respectivamente y el anillo de fricción (7; 54; 71; 83; 93; 107; 205; 304; 305), caracterizada porque al menos uno de los elementos de transmisión rotativos y/o el elemento de acoplamiento se humedecen con un líquido, cuya viscosidad varía con una gradiente de viscosidad dependiente de la temperatura, que se encuentra entre la gradiente de viscosidad (89a) de aceites minerales y la gradiente de viscosidad (89b) de dimetilsiloxanos.
