FIELD: machine building.
SUBSTANCE: invention relates to machine building and rocket and space equipment and can be used in rotary machines, to which there are high requirements for reliability and durability, which operate under zero gravity conditions or in which shafts are located vertically, as a result of which there is no radial load on rolling bearings. Combined drive support comprises housing with two combined bearings arranged in it, each of which consists of rolling bearing and static dynamical bearing operating at rotation of inner ring, located on rotor shaft. Static dynamic bearing has variable working eccentricity, which is ensured by design of outer ring in the form of two eccentric bushings, wherein working eccentricities of both static-dynamic bearings are identical in both value and direction.
EFFECT: reduction of beats and vibrations in rolling bearing due to creation of constant loading force in support at insignificant increase of rolling resistance force in support, which increases reliability and durability of support operation.
