BEARING WITH SLIDING LAYER Russian patent published in 2017 - IPC F16C33/12 F16C33/14 C22C13/02 

FIELD: machine engineering.

SUBSTANCE: bearing with the sliding layer consists of the shape-generating body, with the antifriction bearing alloy on the basis of the copper or aluminium and the galvanic sliding layer, made from the material containing tin, antimony and copper. Tin with antimony in the amount of 0.5…4.9 wt % form the matrix as the solid solution with the addition of cadmium in the amount of 0.5…2.5 wt %, and copper with tin forms the compound Cu₆Sn₅, distributed in this matrix in the form of more solid copper-tin particles, with total copper content in alloy 2…25 wt %. The lead impurity content does not exceed 0.25% and the total impurity content of the remained elements does not exceed 1%.

EFFECT: creation of the sliding layer bearing with improved operating characteristics.
