【 摘 要 】

Many parts of the chassis in forestry machines are exposed to heavy wear due to operation under heavy-duty conditions. Parts exposed to the heaviest wear are friction bearings and axles; whereas it is often cheaper to replace bearings than to restore them, axles might be quite expensive. This study examines a promising method of axle-class parts, improving their wear resistance. Analysis of the study results allows to come to a conclusion that coating produced by electric-contact sintering of composite materials featured a > 1.5x wear resistance of 40Kh steel from which the representative roller axle was made. Therefore, the service life and reliability of joints made of or restored by means of composite materials is considerably better than that of the standard forestry-machine chassis connections.
