THRUST AND RADIAL FRICTION BEARING Russian patent published in 2014 - IPC F01D25/16 F16C17/06 

FIELD: machine building.

SUBSTANCE: invention can be used for design of testbed elements intended for positioning of gyroinstruments during their precision tests. In the thrust and radial friction bearing the surface of one-sheet hyperboloid formed by families of rectilinear generators is used as a contact surface of the thrust and radial friction bearing. The surface of one-sheet hyperboloid is used both for fabrication of the surface of motionless journal of bearing housing, and for fabrication of the contact surface lapping the journal made demountable and compounded from two contacting with minimum diameters plates of parts of insert of swing frame, between which the gap adjusting foil is located. In the plates of the swing frame insert three series of viaholes are made, where in the first series of holes the pins are placed without gap that orienting during assembly uniformly with reference to each other the parts of split insert, in the second series of viaholes the bolts with nuts and showers are installed and screwed to each others for fastening of insert plates, in the third series of viaholes the bolts with nuts and showers are placed for fastening of the plate with payload, meanwhile in both parts of the insert from external sides of the second and third series of holes the recesses are made, where heads of screw bolts and nuts with showers are placed flush.

EFFECT: improvement of position stability at positioning of gyroinstruments, processable, repairable, meanwhile the bearing has a minimized clearance ensuring minimum offset in axial and radial direction from the selected position.
