<p>An antifriction bearing (A, B) having inner and outer races (24, 30, 32) and rollers (6, 34) between the races accommodates axial misalignment of the races and also axial displacement of one race relative to the other. In one form (A), the inner race (2) has a cylindrical raceway (12) presented outwardly, whereas the outer race (4) has a spherical raceway (16) presented inwardly toward the cylindrical raceway. Each roller (6) has two arcuate end surfaces (20) and a cylindrical intervening surface (22). The arcuate end surfaces generally conform to and roll along the spherical raceway, while the cylindrical intervening surface rolls along the cylindrical raceway. In another form (B), the inner race (30) has a spherical raceway (36) that is presented outwardly and the outer race (32) has a cylindrical raceway (38) that is presented inwardly toward the spherical raceway. Each roller (34) has two cylindrical end surfaces (40) and an arcuate intervening surface (42). The rollers contact the cylindrical raceway along their cylindrical end surfaces and the spherical raceway along their arcuate intervening surfaces which generally conform longitudinally to the spherical raceway.</p> |
