摘要： PROBLEM TO BE SOLVED: To provide a spherical roller bearing with a thin plate bearing cage easy to be mounted and free of a removal risk. SOLUTION: The spherical bearing 10 comprises a unit outer ring 12 having a spherical rolling raceway 20 formed thereon, an inner ring 14 having two rolling raceways 22 formed thereon, and the thin plate cage 16 with two recessed portions having rollers 18 in two rows. The cage 16 has two terminal rings, and a radial outside face whose enveloping surface is a rotational surface 60 composed of three portions, namely a cylindrical inside portion 62, a truncated cone shaped outside portion 66, and a truncated cone shaped intermediate portion connecting the inside portion to the outside portion. The truncated cone shaped portion is gradually wider toward the inside portion at a solid angle which is not so much opened as that of the outside portion. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem of a cage for a spherical bearing wherein positioning of rollers housed in a recessed part is unstable.SOLUTION: Bridges 32 of the retainer 16 respectively include: two end parts 82, 86 respectively connected to one of two end rings 28, 30; and an intermediate part 84 connecting the two end parts 82, 86 to each other. The intermediate parts 84 of the bridge 32 mutually set a single intermediate truncated cone shaped geometric surface which includes the whole of the inside surface 74 of the intermediate part 84. The intermediate part 84 includes at least two projection parts 90 projecting toward a recessed part 40 housing rollers. The projection parts 90 respectively include a side edge guide small surface 94 to be rotated toward the recessed part 40, and form an inside pleat 96 together with the inside surface 74. The side edge guide small surface 94 is brought into contact with the same rotating surface rotating around a proper geometric axis 92 of the recessed part 40, and the proper geometric axis 92 forms an angle equal to a half of a solid angle of the intermediate truncated cone geometric surface together with a rotary axis of the retainer 16.
