FILM-LUBRICATION BEARING Russian patent published in 2017 - IPC F16C13/02 F16C33/04 F16C33/20 F16C33/24 

FIELD: machine building.

SUBSTANCE: invention is aimed at further improved in field of film lubrication bearings, and more specifically, to bearings, used for support rolling mill forming roll neck with possibility of rotation. Bearing comprises rotary bushing with external surface, insert, containing support unit (40) with, substantially, cylindrical support surface with low friction coefficient, wherein rotary bushing outer surface rests with possibility of rotation on oil film on support surface with low friction coefficient, and plurality of oil channels, extending through insert for oil supply under pressure between rotary bushing outer surface and insert to create oil film. Support surface is formed by plurality of deformed rods (42). Each of plurality of rods (42) is arranged inside hole (44) in support unit (40) so, that in next production process heat deformation of rods (42) can bring to formation of, substantially, cylindrical support surface. Said production process includes: introduction of polymer rods (42) into support unit (40) drilled holes (44), polymer rods heating to temperature, leading to certain plasticity, introduction of pair of, substantially, semi-cylindrical molds into insert and application of force from outside, by means of hydraulic cylinder with external drive, to molds in support unit (40) direction for deformation of heated polymer rods (42) into, substantially, cylindrical support surface.

EFFECT: technical result: improving operating characteristics.
