ABSTRACT:
An articulated bearing has an inner ring with a spherical outer surface, and an outer ring with a hollow spherical inner surface corresponding to and engaging the outer surface of the inner ring. Plastic bearing segments are circumferentially arranged in the cylindrical bore of the inner ring. The plastic segments are held by rings having inclined ends engaging the ends of the plastic segments. Circumferential displacement of the segments is prevented by strips affixed in the bore of the inner ring between adjacent segments. The plastic segments extend radially inwardly of the holding rings and strips a distance, in the absence of loading of the bearing, corresponding to the elastic deformation of the segments in the loaded condition. A pin in one of the inner and outer rings is urged into a recess in the other of the inner and outer rings, by means of a spring.
