ANTI-FRICTION LAYER FOR BEARING ELEMENT Russian patent published in 2009 - IPC F16C33/04 F16C33/20 B32B27/04 

FIELD: machine building.

SUBSTANCE: invention relates to anti-friction layer for bearing element. Proposed anti-friction layer (4) for bearing element (1), in particular, plain bearing, made in synthetic polymer layer, in particular, rubber or lacquer layer. The said polymer layer consists of the 1^st partial (5) and one 2^nd partial layer (6). Aforesaid layer (5) consists of the 1^st polymer, while layer (6), abutting on locked structural element, consists of the 2^nd polymer, other than the 1^st one. Layer (6) comprises, at least, one lubricant at the amount of 15 wt % to 50 wt %. Layer (5) comprises, at least, one hard consistency lubricant at the amount of 5 wt % to 20 wt %, provided that the amount of, at least, one hard consistency lubricant exceeds that in layer (5). The invention covers also bearing element (1), particularly, plain bearing, with bearing metal layer (2), bearing metal layer (3) applied onto layer (2) anti-friction layer (4) applied onto layer (3). Note here that layer (4) of layer (4) is arranged between layers (6) and (3).

EFFECT: perfected anti-friction layer to sustain higher loads.
