Abstract
An eccentric facing unit wherein a tool driving shaft is concentrically disposed in a spindle for relative rotation with respect to the spindle. A tool-shaft supporting shaft is eccentrically disposed in a spindle and is connected with the tool driving shaft through a geared transmission so as to rotate at speed two times faster than that of the tool driving shaft. A tool shaft is eccentrically disposed in the tool-shaft supporting shaft in an eccentricity equal to that of the tool-shaft supporting shaft with respect to the spindle and is connected through an Oldham's shaft coupling with the tool driving shaft for integral rotation therewith.
Claims2
An eccentric facing unit including a tool driving shaft concentrically disposed in a spindle and relatively rotating with respect to said spindle, a tool-shaft supporting shaft eccentrically disposed in said spindle and connected with said tool driving shaft through a geared transmission so as to rotate at speed twice that of said tool driving shaft, and a tool shaft integrally rotating with said tool driving shaft and eccentrically disposed in said tool-shaft supporting shaft in an eccentricity equal to that of said tool-shaft supporting shaft with respect to said spindle.
