  • Spherical roller bearing assembly
    Patent number: 5207512
    Abstract: A spherical roller bearing is confined in a bearing ring which, in turn, is confined in a bearing housing, the housing and the ring each being of split construction. The housing has a pair of il reservoirs therein separated by a saddle upon which the ring is mounted, and an anti-rotation pin engages both the housing and the ring to prohibit rotation of the latter in the former. The ring, too, has an oil reservoir therewithin. The ring and pin, and accordingly the bearing, are electrically isolated from the housing. An oil ring rides upon a bearing-mounted motor shaft through slots formed in the bearing ring, and is guided by machined reliefs formed in opposite sides of the bearing ring. Holes in the saddle provide for a through-flow of oil between the pair of reservoirs in the housing.
