VERTICAL SHAFT GUIDE BEARING Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: guide bearing of vertical shaft is provided with half-inserts located in its sectional body which have set of segments with rubber lining; they embrace trunnion of shaft with lining. Segments are made from rubber integral with rubber lining. They are provided with end bevels and are mounted in half inserts by barrel scheme. Working surface of each segment is rectilinear and is located tangentially relative to surface of shaft trunnion lining. Each half-insert is spring-loaded relative to body to ensure contact of working surfaces of segment with shaft trunnion lining. Bearing is provided with end shield having inner bevels opposite to end bevels of segments and engageable with these bevels. Shaft trunnion lining is detachable; it consists of two parts mounted on shaft by means of flanges. Screws are provided to regulate force of springs.
