The analysis of physical and mechanical factors determining the service life of bearing units was carried out. The adhesion and adhesion-welding technologies for restoration of bearing seats in the supports of heavily loaded gears were developed. The compositions of repair composite material based on adhesive «Koutex» and the optimal modes of stage-by-stage deposition of coupling, filling and finishing coating layers were selected. The limit values of rheological characteristics of the adhesive compositions for formation of adhesion-welding repair joint were established. 4 Ref., 7 Figures.
