Abstract

A bundle guiding device includes an inner roller mounted on a front portion of a bundle in an insertion direction where the bundle is to be inserted into a casing and configured to roll on an inner peripheral surface of the casing, an outer roller mounted on a rear portion of the bundle in the insertion direction where the bundle is to be inserted into the casing and configured to travel on a rail member, and a position adjusting mechanism configured to adjust a position of the bundle in a horizontal direction orthogonal to the insertion direction by applying an adjusting force to a receiving portion, one of the position adjusting mechanism and the receiving portion being on the bundle, and the other of the position adjusting mechanism and the receiving portion being on one of a base surface and the rail member.

First claim

The invention claimed is:

1. A bundle guiding device of a compressor in which a bundle is to be inserted to a casing, the bundle including a rotor and a stationary part by which the rotor is rotatably supported, the bundle guiding device comprising:
an inner roller that is mounted on a front portion of the bundle in an insertion direction of the bundle and is configured to roll in the insertion direction on an inner peripheral surface of the casing;
an outer roller that is mounted on a rear portion of the bundle in the insertion direction of the bundle and is configured to travel on a rail member fixed onto a base surface on which the casing is disposed;
a position adjusting mechanism that is configured to adjust a position of the bundle in a horizontal direction orthogonal to the insertion direction by applying an adjusting force to a receiving portion in the horizontal direction,
wherein either the position adjusting mechanism or the receiving portion is on the bundle,
wherein either the position adjusting mechanism or the receiving portion which is not on the bundle is on one of the base surface and the rail member, and
wherein the rail member is one of a first pair of rail members, and a second pair of rail members extends inside a track of the first pair of rail members.

2. The bundle guiding device of a compressor according to claim 1 ,
wherein the position adjusting mechanism includes a metal roller configured to roll in the insertion direction while in contact with the receiving portion.

3. The bundle guiding device of a compressor according to claim 1 , wherein the rail member extends in an axial direction of the bundle.

4. The bundle guiding device of a compressor according to claim 1 , wherein a majority of the rail member is outside the casing.

5. The bundle guiding device of a compressor according to claim 1 , wherein the second pair of rail members includes inclined surfaces.

6. The bundle guiding device of a compressor according to claim 1 , further comprising a rear traveling mechanism which is mounted on the bundle and is configured to travel on the rail member.

7. The bundle guiding device of a compressor according to claim 6 , wherein the rear traveling mechanism includes a bracket, a support post, a support portion, and the outer roller.

8. The bundle guiding device of a compressor according to claim 1 , further comprising a first angle steel fixed to the rail member.

9. The bundle guiding device of a compressor according to claim 8 , wherein the first angle steel has an L-shaped cross section.

10. The bundle guiding device of a compressor according to claim 8 , further comprising a second angle steel fixed to the first angle steel.
