ABSTRACT:
A bearing structure for supporting a shaft in a body is disclosed in which a floating bush is fitted over the shaft and the bush is supported in a cylindrical bearing which is fitted fixedly in the body. Lubricant is supplied to the outside of the cylindrical bearing to a clearance between it and the body, and flows through passages in the bearing to a clearance between the bearing and the bush, where it flows through passages in the bush to the clearance between the bush and the shaft. The passages in the bush are radial, whereas the passages in the bearing are preferably inclined at about 45.degree. to the radii, and extend outward in the opposite direction to the normal direction of rotation of the shaft. The number n of passages in the bush is larger than the number m of passages in the bearing; both of these numbers are even; and the angle subtended at the central axis of the shaft by the opening at the inner end of the passages in the bearing is approximately 360.degree./m-360.degree.
