ROLLER BEARING Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: roller bearing has outer and inner races and needle cylindric rolling bodies interposed between the races and having convex working surfaces. The bodies are rotation ellipsoids, the small and middle axes of the ellipsoids being equal. The small and middle axes of the ellipsoids are equal to the largest diameter of the roller. The large axis is equal to the length of the cylindric roller. The sides of the ways of the outer and inner races interacting with the rollers are congruent to the outer side of the roller. EFFECT: enhanced reliability. 2 dwg
