Abstract

A fixture used in a rotary machine which includes a rotary unit which has a rotary shaft, and a stationary unit which rotatably supports the rotary shaft, includes: a plate which comes into contact with an end portion of the rotary shaft; a fastening member which fixes the plate to the end portion of the rotary shaft; and a constraining member which connects the plate and the stationary unit, and constrains the plate from moving with respect to the stationary unit in an axial direction and a rotation direction.

First claim

The invention claimed is:

1. A fixture used in a rotary machine including a rotary unit which includes a rotary shaft, and a stationary unit which rotatably supports the rotary shaft, the fixture comprising:
a plate which is configured to come into contact with an end portion of the rotary shaft;
a fastening member which fixes the plate to the end portion of the rotary shaft; and
a constraining member which connects the plate and the stationary unit, and is configured to constrain the plate from moving with respect to the stationary unit in an axial direction and a rotation direction,
wherein the stationary unit of the rotary machine comprises a cylindrical casing and a head which is provided in an end portion of the cylindrical casing so as to seal a gap between the rotary shaft and the cylindrical casing, and
wherein the constraining member is a bolt which is configured to be screwed into a screw hole provided in the head.

2. The fixture used in a rotary machine according to claim 1 ,
wherein the stationary unit of the rotary machine comprises a thrust bearing which is configured to receive a force applied in the axial direction from the end portion of the rotary shaft and rotatably supports the rotary shaft, and
wherein the plate is configured to come into contact with an opposite side end portion to the end portion of the rotary shaft provided in the thrust bearing.

3. The fixture used in a rotary machine according to claim 1 ,
wherein the stationary unit of the rotary machine further comprises a journal bearing which is fixed to the head, is configured to receive a force applied from the rotary shaft in the radial direction and rotatably supports the rotary shaft, and
wherein the bolt is configured to be screwed into a screw hole provided in the journal bearing.

4. A method for transporting a rotary machine that includes a rotary unit which includes a rotary shaft and a stationary unit which rotatably supports the rotary shaft, the method comprising:
constraining the rotary shaft from moving with respect to the stationary unit in an axial direction and a rotation direction using the fixture used in a rotary machine, according to claim 1 .

5. The fixture used in a rotary machine according to claim 1 ,
wherein fastening member extends through the plate.

6. The fixture used in a rotary machine according to claim 1 ,
wherein the fastening member comprises a head and a body, and
wherein the head of the fastening member is disposed on a first side of the plate, a first portion of the body of the fastening member is surrounded by the plate, and a second portion of body of the fastening member is disposed on a second side of the plate that is opposite to the first side of the plate.
