FRICTION PAD Russian patent published in 2008 - IPC F16D69/02 

FIELD: mechanic.

SUBSTANCE: the invention relates to the area of mechanical engineering, in particular, to friction pads intended for operation in lubricated assemblies. The friction pad is designed as part of a cylindrical shell, on the internal surface of which rectangular grooves are made. The grooves located longitudinally to the pad length have the same width and depth. The grooves transversal to the pad length, have width increasing with the groove depth. This provides stability of friction characteristics of the pad and decreases friction pair wear due to providing of more favourable conditions for penetration of the lubricating oil to the friction contact area, more efficient cooling of the friction elements, and better cleaning of the friction contact area from the wear products.

EFFECT: increased stability of friction characteristics of pad and decreased friction pair wear.
