Abstract

A rotary machine system ( 1 ) includes a first rotary machine ( 4 ) having a driving shaft ( 5 ) capable of being driven about an axis, a second rotary machine ( 2 ) having a driven shaft ( 3 ) rotatable about the axis and a bearing device ( 11 ) slidably supporting the driven shaft ( 3 ) on an axial end portion side with a pad surface ( 37 ) such that lubricating oil is supplied to the pad surface ( 37 ), a coupling unit ( 6 ) connecting the driving shaft ( 5 ) and the driven shaft ( 3 ) to each other such that rotation of the driving shaft ( 5 ) is transmitted to the driven shaft ( 3 ), and a baffle plate ( 7 ) disposed between the bearing device ( 11 ) and the coupling unit ( 6 ) and separating a space on the bearing device ( 11 ) side and a space on the coupling unit ( 6 ) side from each other.

First claim

1 . A rotary machine system comprising:
a first rotary machine including a driving shaft capable of being driven about an axis; a second rotary machine including 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.

2 . The rotary machine system according to claim 1 ,
wherein the coupling unit includes a disk-shaped disk portion protruding in a radial direction of the driving shaft and the driven shaft.

3 . The rotary machine system according to claim 1 ,
wherein the baffle plate includes a plurality of support units disposed at intervals in a circumferential direction, and wherein the baffle plate is supported by an inner peripheral surface of a casing of the first rotary machine or the second rotary machine via the support units.

4 . The rotary machine system according to claim 2 ,
wherein the baffle plate includes a plurality of support units disposed at intervals in a circumferential direction, and wherein the baffle plate is supported by an inner peripheral surface of a casing of the first rotary machine or the second rotary machine via the support units.
