Cylindrical roller bearings<\/a>\u00a0Los rodamientos de rodillos cil\u00edndricos est\u00e1n disponibles en una variedad de dise\u00f1os, series y tama\u00f1os. Los rodillos de los rodamientos de rodillos cil\u00edndricos son componentes clave. Su geometr\u00eda, el llamado perfil logar\u00edtmico, proporciona una distribuci\u00f3n \u00f3ptima de las tensiones en las zonas de contacto del rodamiento. Su acabado superficial maximiza la formaci\u00f3n de una pel\u00edcula lubricante y optimiza el movimiento de rodadura de los rodillos. Los beneficios derivados de esto en comparaci\u00f3n con los dise\u00f1os tradicionales incluyen una mayor confiabilidad operativa y una mayor insensibilidad a la desalineaci\u00f3n.<\/p>\n

La gama de rodamientos de rodillos cil\u00edndricos comprende los tipos b\u00e1sicos.<\/p>\n

>>rodamientos de una hilera de rodillos cil\u00edndricos, enjaulados, principalmente de los dise\u00f1os NU, NJ, NUP y N.<\/p>\n

>>rodamientos de dos hileras de rodillos cil\u00edndricos, enjaulados, principalmente de los dise\u00f1os NNU y NN.<\/p>\n

>>Rodamientos de rodillos cil\u00edndricos de una hilera sin jaula, principalmente de dise\u00f1os NCF y NJG.<\/p>\n

>>Rodamientos de dos hileras completamente llenos de rodillos cil\u00edndricos, principalmente del dise\u00f1o NNF.<\/p>\n

Los rodamientos de rodillos cil\u00edndricos con jaula pueden soportar cargas radiales pesadas y funcionar a altas velocidades. Los rodamientos de rodillos cil\u00edndricos totalmente llenos son adecuados para cargas radiales muy pesadas a velocidades moderadas.<\/p>\n

Los rodamientos de rodillos cil\u00edndricos tienen una alta capacidad de carga, fueron ampliamente utilizados en maquinaria agr\u00edcola, motores grandes y medianos, equipos de material rodante, husillos de m\u00e1quinas herramienta, motores de combusti\u00f3n interna, generadores, turbinas de gas, cajas de engranajes, laminadoras, cribas vibratorias y maquinaria de elevaci\u00f3n, etc.<\/p>\n

\"\"<\/p>\n

En un rodamiento de rodillos cil\u00edndricos de una hilera, los rodillos siempre se gu\u00edan entre las bridas integrales \"abiertas\" de uno de los anillos. Estas bridas \"abiertas\", combinadas con los extremos de los rodillos especialmente dise\u00f1ados y con acabado superficial, proporcionan una mejor lubricaci\u00f3n, una menor fricci\u00f3n y, en consecuencia, una temperatura de funcionamiento m\u00e1s baja.<\/p>\n

El anillo con las pesta\u00f1as integrales junto con el conjunto de jaula y rodillo cil\u00edndrico se pueden separar del otro anillo. Esto resulta en un f\u00e1cil montaje y desmontaje, particularmente cuando las condiciones de carga son tales que se requieren ajustes de interferencia para ambos anillos.<\/p>\n

Nuestros rodamientos de rodillos cil\u00edndricos de una hilera pueden soportar cargas radiales pesadas y altas velocidades. Se fabrican en varios dise\u00f1os diferentes, estando la principal diferencia en la configuraci\u00f3n de las bridas.<\/p>\n

dise\u00f1o NU<\/p>\n

El aro exterior de un rodamiento de dise\u00f1o NU tiene dos pesta\u00f1as integrales, mientras que el aro interior no tiene pesta\u00f1as (a). El desplazamiento axial del eje con respecto a la carcasa puede realizarse en ambas direcciones.<\/p>\n

dise\u00f1o n<\/p>\n

El aro interior de un rodamiento de dise\u00f1o N tiene dos pesta\u00f1as integrales, mientras que el aro exterior no tiene pesta\u00f1as (b). El desplazamiento axial del eje con respecto a la carcasa puede realizarse en ambas direcciones.<\/p>\n

dise\u00f1o NJ<\/p>\n

El aro exterior de un rodamiento de dise\u00f1o NJ tiene dos pesta\u00f1as integrales y el aro interior tiene una pesta\u00f1a integral (c). Estos rodamientos pueden ubicar el eje axialmente en una direcci\u00f3n.<\/p>\n

dise\u00f1o NUP<\/p>\n

El aro exterior de un rodamiento de dise\u00f1o NUP tiene dos pesta\u00f1as integrales y el anillo interior tiene una pesta\u00f1a integral y una pesta\u00f1a no integral en forma de anillo de pesta\u00f1a suelta (d). Estos cojinetes se pueden utilizar como cojinetes de ubicaci\u00f3n para ubicar el eje axialmente en ambas direcciones.<\/p>\n

Ejecuci\u00f3n NU+HJ<\/p>\n

Se puede utilizar un rodamiento tipo NU combinado con un anillo angular HJ (e) para ubicar el eje axialmente en una direcci\u00f3n. SKF recomienda no montar anillos angulares est\u00e1ndar en ambos lados de un rodamiento tipo NU, ya que esto puede provocar una compresi\u00f3n axial de los rodillos.<\/p>\n

Ejecuci\u00f3n NJ+HJ<\/p>\n

Se puede utilizar un rodamiento tipo NJ combinado con un anillo angular HJ (f) para ubicar el eje axialmente en ambas direcciones.<\/p>\n
