A rotary machine system () includes a first rotary machine () having a driving shaft () capable of being driven about an axis, a second rotary machine () having a driven shaft () rotatable about the axis and a bearing device () slidably supporting the driven shaft () on an axial end portion side with a pad surface () such that lubricating oil is supplied to the pad surface (), a coupling unit () connecting the driving shaft () and the driven shaft () to each other such that rotation of the driving shaft () is transmitted to the driven shaft (), and a baffle plate () disposed between the bearing device () and the coupling unit () and separating a space on the bearing device () side and a space on the coupling unit () side from each other.

Rotary machine system

A rotation mechanism includes a casing with an upper half portion and a lower half portion; and an internal unit disposed in the casing with a rotor rotating around an axis thereof. Additionally, a bearing portion rotatably supports the rotor, and an annular seal portion seals a gap surrounding a circumferential surface of the rotor. An axial movement restricting portion includes a fitting concave portion on one of the casing and the internal unit, and a fitting convex portion to be fitted into the fitting concave portion as a pair, which restricts relative movement between the casing and the internal unit in a direction of axis. A tapered surface is formed on the fitting concave portion and the fitting convex portion and a width thereof in the direction of axis increases toward an inner circumferential side in a radial direction.
