Abstract

PURPOSE:To prevent the mixing of dust into the lubrication oil by mounting the enlarged section of a piece on the outer-circumference at the lower end of a rotary shaft thereby using the space between the enlarged section and the lower end face of the rotary shaft as the dust sump. CONSTITUTION:A piece 22 is mounted on the outer-circumference at the lower end of a steel pipe rotary shaft 21. The piece 22 is comprising an oil supply pump section 22c, small diameter section 22b and an enlarged section 22a. The enlarged section 22a will form a convex space section 23 having the diameter larger than the inner diameter of the rotary shaft between the lower end face 21a of the rotary shaft. Upon the rotation of the rotary shaft 21, the centrifugal force is produced on the oil supply pump 21c to attract the dust 12 such as the iron powder together with the lubrication oil. The dust 12 is centrifugally separated to the space section 23 or the dust sump section 23.
