The aim of the work is a design substantiation of sliding bearings with wedges made of new antifriction reinforced wood-metal materials having increased tribo-technical properties ensuring potentialities for their industrial use widening.
The wear investigation of the materials offered was carried out according to the procedure providing for an abrasive impact at that besides wear-resistance the thermo-physical characteristics of samples under analysis were assessed. As a result of the investigation there was offered a structure of anti-friction materials combining in them modified wood and a metal filling agent made of different antifriction materials or special capsules filled with fusible materials and also wedges made by means of a joint coiling of a metal band or an element as tensile anti-friction springs and sized bands of veneer.
The offered reinforced composite sliding bearings allow ensuring higher mechanical and tribo-technical characteristics to a considerable extent, optimizing a thermal working mode of sliding bearing wedges, increasing considerably their manufacturability and widening a sphere of industrial use by means of rational combining different wood types and metal composite constituents.
