BOLTED JOINT OF ROTATING PARTS Russian patent published in 2013 - IPC F16B5/02

Abstract RU 2472981 C1

FIELD: machine building.

SUBSTANCE: bolted joint of rotating parts combined in a pack with holes arranged in a circumferential direction inside of which there are sleeves installed to the height of parts pack with coupling-bolts arranged in their central holes. Each hole is of oval shape and it is elongated in circumferential direction, and sleeve is with oval section elongated in circumferential direction. At that b/a=1.36-1.5; 0(2.5-3)×b, where a is size of sleeve section in radial direction; b is size of sleeve section in circumferential direction; c is length of circumference between central holes of adjacent sleeves.

EFFECT: increasing cyclic life and reliability of bolted joint of rotating parts under high working parameters by means of relief of stress concentration zones in mentioned parts.
