Abstract

Abstract In this bearing for light rotary shafts, a metal receiving plate provided with a hemispherical recess of a diameter slightly larger than the outside diameter of a spherical bearing metal is formed, an annular felt impregnated with a lubricating oil is fitted to said metal receiving plate, the intermediate periphery of the spherical bearing metal is fitted to said annular felt, further an annular metal pressing plate having the edge part of an inner hole formed to be of an arc of a diameter slightly larger than the outside diameter of the spherical bearing metal is placed on said annular felt, the spherical bearing metal pressing plate by leaving a very slight clearance between it and the arc of the inner hole of said annular metal pressing plate and between it and the hemispherical recess of the metal receiving plate and the metal receiving plate and annular metal pressing plate are integrally combined with each other by filling an annular groove formed of the peripheral edge step part of the annular metal pressing plate and the inner peripheral surface of the metal receiving plate with an organic binder.
