Zusammenfassung:manufacture of sliding bearing assemblies with applied antifriction layer such as bearing assemblies for submerged electric pumps. SUBSTANCE: metered briquette of babbitt is placed into recess of bearing base. Briquette may be made of powder, its shape corresponds to that of recess. Briquette is heated until melting it in protective reduction atmosphere of hydrogen. Formation of casting blisters and pores is eliminated as there is no stage of metal casting and also due to reduction in hydrogen medium surface oxide film occurring at melting babbitt. Ready bearing with monolithic babbitt layer has thin-fibber structure with uniform distribution of rigid and soft ingredients. EFFECT: enhanced quality of bearing assemblies with uniform layer of babbitt. 3 dwg
