초록

A shaft support device for a turbomachine including a rotary body and a stationary body. The rotary body is attached to a shaft of the turbomachine, and includes a first portion and a second portion. The first portion has a thrust bearing collar and the second portion has a thrust balance piston. The first and second portions are axially overlapping. The stationary body is fixably attached to a casing of the turbomachine. The stationary body has a first thrust bearing portion that is disposed adjacent to and operatively engages the first portion of the r...
