| Abstract:In order to study the mechanismand law of contact state change of curvic-coupling of turboshaft engine rotor, the influencing
factors of contact state for curvic -coupling joint structure were determined according to the structure characteristics, mechanics
characteristics, and force principle of tangential contact considering sliding, and the changing rule of contact state for curvic-coupling was
studied by finite element analysis method. The calculating results indicate that revolving speed and axial preload have important effects on
curvic-coupling contact state; the greater the revolving speed is, the smaller the contact area is, and the greater the contact stress and
sliding distance are; the greater the axis preload is, the greater the contact area is, and the greater the contact stress and sliding distance are;
and the influence of friction coefficient on contact state is not obvious. The study results provide technical guidance of structure design for
rotor with curvic-coupling. |
