RADIAL SPHERICAL FACE SLIDE BEARING
Document Type and Number:
Japanese Patent JP2017040275
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a radial spherical face slide bearing which can easily cope with the other use condition while being usable at the non-supply of oil in a support use of one direction load particularly.SOLUTION: A spherical inner face 3 of an outer ring 4 is formed of a first semi-spherical recessed face 9 which is formed at an internal peripheral half-peripheral side of annular parts (5, 12) of the outer ring 4, and a second semi-spherical recessed face 10 including a lubricant 13 which is anchored to only an internal peripheral half-peripheral side which is opposite to the first semi-spherical recessed face 9. By this constitution, the first semi-spherical recessed face 9 or the second semi-spherical recessed face 10 which is arranged at a side to which a radial load is applied is selected, and the load can be applied to a slide contact face between the selected semi-spherical recessed face and a spherical outer face 1. A radial spherical slide bearing becomes usable in an oil non-supply condition by the second semi-spherical recessed face 10 including the lubricant 13. Also, the radial spherical slide bearing is utilized in use in the other use condition by the first semi-spherical recessed face 9.SELECTED DRAWING: Figure 1
