Abstract

CIGUEÑAL PARA UN MOTOR DE COMBUSTION INTERNA, TOTAL O PARCIALMENTE ENSAMBLADO A PARTIR DE BRAZOS DE CIGUEÑAL (2) Y ELEMENTOS DE MUÑEQUILLA (5) UNIDOS POR CONTRACCION. POR LO MENOS UNA DE LAS CARAS COINCIDENTES DE AJUSTE POR CONTRACCION ESTARA PROVISTA DE UN MATERIAL QUE INCREMENTA LA FRICCION, QUE PUEDE CONSISTIR EN UN RECUBRIMIENTO DE NIQUEL O EN PARTICULAS SENSIBLEMENTE MAS DURAS QUE EL MATERIAL BASICO DEL BRAZO O DEL ELEMENTO DE MUÑEQUILLA, O EN UN RECUBRIMIENTO COMBINADO CONSTITUIDO POR PARTICULAS DURAS (10) EMPOTRADAS EN UNA MATRIZ DE NIQUEL (11, 12). EL RECUBRIMIENTO QUE INCREMENTA LA FRICCION AUMENTA LA CAPACIDAD DE TRANSMISION DE PAR DE LAS CARAS DE AJUSTE POR CONTRACCION PARA QUE SE REDUZCAN LAS TENSIONES DE CONTRACCION, POSIBILITANDO LA FABRICACION DE CIGUEÑALES DE MENOR PESO.
