FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to manufacture of bearing units forming supports of rotating parts of machines. Proposed method includes assembling of antifriction bearing from outer and inner races, solids of revolution, cage, bearing shields, mounding of bearing race into plasticized material of part of mechanism and mounting part with bearing into housing of mechanism with forming of support unit and adjusting of clearances to preset fits. Race is molded into plasticized material of blank separately from bearing. Blank is located to free surface of race on machine tool and is machined to get size and shape of required accuracy and ready part with molded-in race is assembled into antifriction bearing as common assembly unit. ^ EFFECT: increased accuracy of manufacture, longevity and rigidly of parts of bearing unit. ^ 2 dwg |
