FIELD: machine building.
SUBSTANCE: rotary machine support, which includes stator housing and ceramic bearing, the outer race of which is installed in stator housing, as opposed to the known one, includes the flange fixed on the stator housing and packing sleeve installed between flange and one of the edges of bearing outer race; one of edges of packing sleeve has conic surface contacting the mating conic surface of the flange, and external surface of bearing outer race is conic and contacts the mating conic surface of stator; at that, packing sleeve is made from composite material, and flange is made from the material, the thermal expansion coefficient of which is higher than that of bearing material.
EFFECT: maintaining the fit of ceramic outer race of bearing relative to stator in metal housing at increase in temperature state of support; providing easy erection and dismantling of bearing outer race.
