Abstract:
A method for aligning a freely carrying bearing assembly mounted on a dryer cylinder in paper-making machine, the freely carrying bearing assembly including an outer race, an inner race, and a plurality of rollers therebetween, the inner race coupled with a journal of the dryer cylinder by a locknut, the method comprising the steps of:mounting a seating structure onto the outer race, the seating structure adapted to be fixedly mounted relative to the journal; fixedly mounting the seating structure relative to the journal; providing an alignment plate having an opening therein sized to receive the journal, a plurality of measurement slots radially extending from the opening and equally radially spaced thereabout, and a plurality of mounting bores; attaching the alignment plate onto one side of the seating structure with use of the plurality of mounting bores, wherein the journal extends through the opening; mounting an inner cover to another side of the seating structure; maintaining the outer race against the inner cover; determining a desired outer race to inner race offset; determining an existing outer race to inner race offset relative to the alignment plate by utilizing measurements taken through the plurality of measurement slots; determining a correction outer race to inner race offset between the determined desired outer race to inner race offset and the determined existing outer race to inner race offset; and axially aligning the seating structure according to any determined correction outer race to inner race offset.
