Abstract

PURPOSE: To prevent partial stress concentration of the rotor shaft of a rotary machine by providing an intermediate-diameter shaft at the intermediate portion between a small-diameter shaft and a large-diameter shaft integrated therebetween and large radius R at each of the rounded corners of stepped portions thereamong with a stepped portion provided at the inner peripheral surface of a revolving ring to be engaged with the large-diameter shaft.
CONSTITUTION: An intermediate-diameter portion ϕ3 is provided integrally between small-diameter portion ϕ4 making contact with a bearing and large- diameter portion ϕ5 disposed with lubricating oil supplying revolving ring 4 at the bearing portion of the revolving shaft 1 of a rotary machine with a stepped portion provided at each thereamong with large radius R at each of the rounded corners thereof. In addition, a stepped portion is provided at the inner peripheral surface of the revolving ring 4 to engage the ring 4 with the large-diameter shaft. Thus, it reduces the partial stress concentration at the stepped portions of the shaft, and, since there is no stepped portion for engaging the revolving ring at the large-diameter portion, it can eliminate the stress concentration caused thereby.
