RADIAL ARTICULATED-SPHERICAL MODULE OF PINUS COMPLEX BY TYPE OF FRICTION (VERSIONS) Russian patent published in 2011 - IPC F16C21/00 F16C23/08 F16C35/73 F16C35/77 

FIELD: machine building.

SUBSTANCE: radial articulated-spherical module complex by type of friction consists of rolling bearing including external and internal rings, separator and elements of rolling friction, and also of articulated-spherical, radial cylinder and end bearings made out of anti-friction self-lubricating composite. Also, internal surface of the internal ring of the rolling bearing is spherical, whereon there is secured the spherical friction bearing in kinematic conjugation with the internal ring of the articulated-spherical friction bearing, external surface of which is spherical. The internal ring of the rolling bearing is simultaneously the external ring of the articulated-spherical friction bearing. The radial cylinder and end support or thrust friction bearings are arranged on internal cylinder and on end surfaces of the internal ring of the articulated-spherical friction bearing. According to the second version the spherical friction bearing is fixed on spherical surface of the external ring of the articulated-spherical friction bearing; the spherical friction bearing is in kinematic connection with the external ring of the rolling bearing. Its external surface is made spherical. The radial cylinder and end friction bearings are secured on cylinder and end surfaces of the internal ring of the rolling bearing.

EFFECT: raised reliability and essentially increased resource of friction supports at operation under emergency conditions.
