SLIDING BEARING Russian patent published in 2018 - IPC F16C17/00 F16C33/04 F16C33/26 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, in particular to machine parts, and can be used in bearing units of shafts and axes of mechanisms and machines. Bearing contains shaft (2) mounted on journal (1), mounted in support housing (3), antifriction liner in the form of a helical spiral made of filament (4) of circular cross-section laid along the circumference of the trunnion along its length and fixed by its ends at the ends of the trunnion. Distance between the turns of the helix along the length of spigot (1) is variable, varying from maximum along the center of pin (1) to minimum, down to its zero value, near the ends of journal (1). In trunnion surface (1), a helical groove is made in response for the spiral coils, the depth of which is not more than the radius of the spiral thread, and into which the turns of this spiral are laid.

EFFECT: technical result: optimization of the design of the bearing of sliding and increase of its durability and reliability of its work.
