mechanical engineering. SUBSTANCE: shell has engagement sublayer and antifriction lining positioned above it made of metal alloys and arranged on internal surface in succession and concentrically. Engagement sublayer is made of alloy containing the following ratio of components, mas.%: nickel, 89-89.2; aluminum, 5.9-5.8; molybdenum, 5.1-5.0. Antifriction lining may be made of alloy containing the following ratio of components, mas.%: aluminum, 80-78; tin, 20-22. Antifriction lining may also be made of alloy containing the following ratio of components, mas.%: babbitt, ‡83 GOST 1320-74, 85-90; and molybdenum disulfate, 15-10. EFFECT: enhanced reliability of operation. 3 cl, 3 dwg, 1 tbl
