Abstract

Un método para alinear un cojinete (52) para un rodillo (34) que se configura para soportar un cuerpo (22) rotatorio, el método caracterizado porque comprende: unir un detector (75) de basculamiento al cojinete (52), en donde el detector (75) de basculamiento genera una señal relativa a la orientación del cojinete; detectar de manera mensurable una inclinación o basculamiento del cojinete (52), en donde el basculamiento se define como una diferencia angular en la orientación del cojinete (52) entre una primera posición del cojinete y una segunda posición del cojinete subsiguiente, que es provocada por una carga de empuje axial en el cuerpo (22) rotatorio; y realizar un ajuste sesgado en el rodillo (34) para devolver el cojinete (52) a sustancialmente la primera posición del cojinete.

asociado) a la posición de empuje neutra asociada. Tal compensación se hace mientras que el horno 10 rotatorio está en funcionamiento, o, en otras palabras, mientras el tubo 22 esta girando. Además, la orientación del basculamiento de cojinetes múltiples para un tubo se puede equilibrar, como cada uno afectará el otro. Así, la orientación del cojinete de cada cojinete se puede ajustar como una función de la inclinación o basculamiento detectado de ese cojinete y la dirección determinada del basculamiento de ese cojinete, y como una función del basculamiento detectado de otros cojinetes y las direcciones determinadas del basculamiento de aquellos otros cojinetes.
