Claims (1)

[Claims for Utility Model Registration] (1) Between the inner peripheral surface of a recessed hole with a circular cross section formed at the center of the end face of the drive shaft and the outer peripheral surface of the end of the driven shaft inserted into this recessed hole. To the installed rolling bearing,
A rolling bearing lubricating device that feeds lubricating oil around the drive shaft, with one end on the outer circumferential surface of the step for positioning the drive shaft formed on the outer circumferential surface of the drive shaft, and the other end on the inner circumferential surface of the recessed hole. Oil passages each having an open end are provided eccentrically rearward in the rotational direction than the diameter position of the cross section of the drive shaft, and a ring-shaped introduction plate and a ring-shaped introduction plate fixed to the introduction plate are provided on the positioning step. A lubricating oil guide member consisting of an introduction vane is fixed, and the introduction vane of this lubricant oil guide member is made to face one end opening of the oil passage, and the distance between this introduction vane and the outer circumferential surface of the stepped portion is adjusted rearward in the rotational direction. A lubricating device for rolling bearings that is narrower towards the end. (2) The lubricating device for a rolling bearing according to claim 1, wherein the inner circumferential surface of the recessed hole forms an inner raceway of the rolling bearing, and the outer circumferential surface of the end of the driven shaft forms an outer raceway of the rolling bearing. . (3) The lubricating device for a rolling bearing according to claim 1 or 2, wherein the other end of the oil passage opens into an oil reservoir formed at the back of the recessed hole. (4) The rolling bearing lubrication device according to claim 2, wherein the other end of the oil passage opens into a part of the inner raceway formed in the inner peripheral surface of the recessed hole.
