FIELD: mechanical engineering. SUBSTANCE: shaft 5 has projecting flange 6. Assembly of flywheels 7,8,9 having central opening is mounted on shaft 5. The number of the flywheels, which are interconnected and connected with the flange by way of tightening bolts 22, is changeable. Bushing 10 having the trancated conical part with axial grooves defining ring segments, is interposed at least between one of the flywheels and the shaft. When connecting, the segments of the bushing are tightened flexibly in the radial direction when they are brought into a contact with the conical surface of the central opening and thereby clearance in the connection is taken up. Each bushing 10 is secured to the flywheel by screws 19. To facilitate disassembling, through openings 20 are made in the flywheels. EFFECT: enhanced reliability. 2 cl, 6 dwg
