<p>PROBLEM TO BE SOLVED: To improve radial load resistance by fitting a spacer which is journaled between an inner ring and it, maintains a clearance between the inner ring and an outer ring, and keeps a prescribed interval to the outer ring so as to perform the identical function to a journal bearing. SOLUTION: This bearing is provided with an upper inner ring 20 and a lower inner ring 30 of hemispherical type fixed so as to face a shaft 10, hemispherical grooves 50a, 50b connected to the inner rings, an outer ring 50 connected to the shaft 10 so as to rotate, connecting rings 60a, 60b which pressure bonding the inner rings 20, 30 so a not to come off the shaft 10, and a spacer 70 which keeps a clearance between the inner rings 20, 30 and the outer ring 50. The connecting rings 60a, 60b are fitted or screwed onto the shaft 10. The spacer 70 supports radial force in the same manner as the journal bearing, and load resistance in the radial direction of the bearing increases as the spacer 70 can support the higher radial load. It is thus possible to improve radial load resistance without changing the whole size.</p> |
