Rodamientos de rodillos cónicos de cuatro hileras
Introducción
Los rodamientos de rodillos cónicos de cuatro hileras pueden soportar cargas combinadas (radiales y axiales) a velocidades de bajas a moderadas.Se utilizan casi exclusivamente en aplicaciones de rodillos de trabajo, como trenes de laminación.
Cuatro filas de rodamientos de rodillos cónicos se han utilizado con éxito en la configuración de rodamientos de trenes de laminación en todo el mundo con velocidades de laminación de baja a media velocidad.Debido a su diseño, el cojinete puede soportar cargas radiales además de las cargas axiales presentes en dichas aplicaciones y, por lo general, no se requieren cojinetes de empuje adicionales en la configuración del cojinete.Esto significa que el eje del rollo puede ser relativamente corto y los alojamientos en ambos lados del rollo pueden tener el mismo diseño.
Los rodamientos de rodillos cónicos de cuatro hileras son los rodamientos de rodillos de diámetro más utilizados.Esta estructura tiene una gran capacidad de carga y puede soportar simultáneamente cargas radiales y axiales combinadas basadas en cargas radiales.Su capacidad de carga radial es de aproximadamente 2,5 a 3,5 veces mayor que la de los rodamientos de una hilera y puede soportar grandes cargas radiales y cargas axiales.
Características y Beneficios
● Instalación simplificada debido a la menor cantidad de componentes
● Distribución de carga mejorada de los rodillos de cuatro hileras, lo que reduce el desgaste y prolonga la vida útil
● El posicionamiento axial en el muñón del rodillo se simplifica debido a la reducción de la tolerancia del ancho del aro interior
● Las dimensiones son las mismas que las de los rodamientos de cuatro hileras de rodillos cónicos convencionales con aros intermedios
Solicitud
Los rodamientos de rodillos cónicos de cuatro filas se utilizan en máquinas pesadas, como grandes molinos fríos y calientes en la industria de maquinaria de plástico.
