METHOD OF SLIDING BEARING BUSHING MANUFACTURING Russian patent published in 2020 - IPC F16C33/04 F16C33/12 B23P6/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and repair, can be used both in production of new parts, and in reconditioning of worn-out parts, in particular, sliding bearings. Method of bearing bushing manufacturing includes production of bushing with outer diameter equal to mounting diameter of assembly, in which bushing is installed, and mechanical application of microrelief on inner surface of bushing. On the inner surface of the bushing made of antifriction material, with applied microrelief, a film antifriction coating is applied, which, in combination with microrelief, provides the formation of microvolumes to retain lubricant.

EFFECT: increased service life of sliding bearing during start-up, shutdown and reverse.
