Abstract
A reduction mechanism for mill comprises a planetary gear train comprising a sun gear, planet gears, an internal gear and a carrier for supporting the planet gears; an input shaft for feeding power; a sun gear shaft on which the sun gear is mounted; an intermediate shaft interposed between the sun gear shaft and the input shaft; an output table for transferring rotary power; a thrust bearing for supporting the output table; and a case for enveloping the planet gear train and the thrust bearing. A tilting pad type bearing is used for the thrust bearing. The thrust supporting portion of the tilting pad type bearing is formed spherically. The center of the spherical surface is positioned between inside and outside diameters of a vertical portion of the case which receives a thrust force.
