METHOD OF RECLAIMING PLAIN BEARING Russian patent published in 2011 - IPC B23P6/00 C23C4/02 B05D3/12 C23C4/06 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and repair, particularly, to plain bearing recovery. Proposed method comprises sleeve pre-machining, cutting irregular thread with skewed subsequent reticule rolling, gas thermal deposition and mechanical processing. Skewed reticule rolling is performed to sleeve ID reduction by 0.5-1.0 mm of ribbing pitch to produce truncated-cone elements on sleeve surface. Deposition is carried out using bronze powder "ПР-Б" 83 (babbit metal). Proposed method allows increasing bearing operating performances, for example, adhesion strength - by 12%, relative wear resistance - by 20%, and relative bearing capacity - by 50%.

EFFECT: material saving, higher mechanical properties.
