SLIDING BEARING (VERSIONS) Russian patent published in 2002 - IPC

FIELD: mechanical engineering; sliding bearings. SUBSTANCE: sliding bearing with ceramic friction pairs can be used in friction units designed for operation in aggressive media containing abrasives at wide temperature and pressure ranges. Bearing has ceramic fixed outer holder and movable inner bushing in which flexible bushing is tightly fitted-in. Flexible bushing is made stepped over entire length, stepped surface being formed by central and end sections. Central section is provided with through longitudinal slots in cross section which can be made inclined and symmetrically. Central section can be made in form of double-start flat spring. EFFECT: prevention of breaking tension stresses in movable bushing of ceramic friction pair. 3 cl, 4 dwg
