MULTI-TIER BEARING WITH EVEN NUMBER OF TIERS AND METHOD OF ITS ASSEMBLING Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: multi-tier bearing has outer, inner and intermediate races. Between the races are radial rolling bodies. The members for stabilizing rotation of the intermediate races are made up as stop rotating bodies. The stop rotating bodies are mounted in two rows from both sides from the radial ones arranged at least in one row. Each odd intermediate race is H-shaped in cross section. Each even intermediate ring is monolithic. According to another embodiment each odd intermediate ring is monolithic. Each even race is H-shaped in cross- section. The inner and outer races are [ - shaped in cross-section. Assembling of the bearing comprises setting halves of H-shaped and [ - shaped races on a plane. The races receive stop rolling bodies of the first row of all tiers. The monolithic races, which are provided with radial rolling bodies of all tiers and rows, are then mounted. The stop rolling bodies of the second row of all ties are mounted on these rolling bodies. The second halves of the H-shaped and [ - shaped races are then mounted and secured to the first halves. EFFECT: improved design. 6 cl, 2 dwg
