RADIAL SLIDING BEARING Russian patent published in 1999 - IPC

FIELD: machine units. SUBSTANCE: radial sliding bearing includes bush mounted in body at negative clearance. Outer and inner surfaces of bush are cylindrical in shape; generatrix of each surface is formed by similar arcs whose convexities are directed outside from axis of bush at coincidence of angular position of arcs of outer and inner cylindrical surfaces. Radius of each arc exceeds radius of circle circumscribed around diametric section of outer cylindrical surface of circle whose radius exceeds radius of hole in body. Each arc has radius exceeding the radius of circle inscribed in diametric section of inner cylindrical surface of circle. Sliding bearing is provided with polymer bush; thickness of wall of this bush is reduced due to special form of bush with no change in resistance to high stresses of compression near friction surface. EFFECT: enhanced reliability of bearing. 3 dwg
