ツトの潤滑装置。[Claims for Utility Model Registration] (1) A lubricating device for a spindle unit in which several locations in the axial direction of a spindle are each supported by a housing via rolling bearings, wherein a plurality of lubricating oil passages are formed in the housing. A bearing lubrication flow path communicating with the lubricating oil flow path and supplying lubricating oil to each of the rolling bearings is formed adjacent to the rolling bearing, and communicating with the lubricating oil flow path. Further, an annular spindle cooling flow path surrounding the spindle is formed between axially adjacent rolling bearings and is separated from the bearing lubrication flow path, and the spindle cooling flow path and the bearing lubrication flow path are formed separately from the bearing lubrication flow path. A lubricating device for a spindle unit, characterized in that cooling oil and lubricating oil are separately supplied to different lubricating oil passages. (2) A lubricating device for a spindle unit in which several locations in the axial direction of the spindle are each supported by a housing via rolling bearings, wherein a plurality of lubricating oil passages are formed in the housing, and the lubricating oil passages are formed in the housing. A bearing lubrication flow path communicating with the rolling bearings and supplying lubricating oil to each of the rolling bearings is formed adjacent to the rolling bearing, and communicating with the lubricating oil flow path and supplying lubricating oil to each of the rolling bearings adjacent in the axial direction. An annular spindle cooling flow path surrounding the spindle is formed between the spindle cooling flow path and the bearing lubrication flow path. A spindle unit lubrication device characterized in that a lubricating oil flow path is shared.
