Abstract
Se suministra un ensamble de cigüeñal de tipo túnel que tiene contrapesos que funcionan para retener el movimiento axial de los cojinetes y mejorar el balance del ensamble de cigüeñal como un resultado de contar con una estructura de un perfil radial incrementado. Los contrapesos pueden incluir una sección de masa y una sección de retención de cojinete. Cuando el contrapeso es asegurado a un brazo de manivela, la sección de masa del contrapeso está espaciada axialmente de un ensamble de cojinete dispuesto alrededor del brazo. Por lo tanto, la sección de masa del contrapeso puede extenderse radialmente más allá de una pista interior del ensamble de cojinete sin contactar la jaula del ensamble de cojinete. La sección de masa del contrapeso no se extiende radialmente más allá de una envolvente radial de una superficie de soporte de cigüeñal con ello permitir que el ensamble de cigüeñal sea insertado deslizablemente dentro del cárter.
