Provided is a compressor that is capable of, with a simple configuration, facilitating the insertion operation of a compressor bundle by reliably preventing tilting thereof during insertion into a chamber; and that also makes it possible to reduce a roller size without increasing the contact pressure of rollers for sliding the compressor bundle. A small tilt sensor that detects a relative angle difference θ of the compressor bundle with respect to the bundle casing is provided at at least one location in the compressor bundle to be inserted into the chamber inside the bundle casing. In addition, the weight of the compressor bundle during the insertion into the chamber is supported by rollers provided at a bottom portion near the front end of the compressor bundle by making the rollers come in contact with an inner circumferential wall surface of the chamber.

1. A compressor configured such that a compressor bundle, in which a rotor, rotor blades, and stator blades are included inside a substantially cylindrical bundle housing, is inserted, from the rear to front in an axial direction, into a horizontally extending, substantially cylindrical chamber formed inside the bundle casing, and outer diameter fitting portions provided at the front end and rear end of the compressor bundle tightly fit with inner diameter fitting portions provided at the front end and rear end of the bundle casing, thus positioning the compressor bundle, the compressor comprising relative angle difference detecting means, provided at at least one location in the compressor bundle, for detecting a relative angle difference of the compressor bundle with respect to the bundle casing. 2. A compressor according to claim 1, wherein the weight of the compressor bundle during the insertion into the chamber is supported by a roller provided at a bottom portion near the front end of the compressor bundle by making the roller come in contact with an inner circumferential wall surface of the chamber; andthe relative angle difference detecting means is provided near the rear end of the compressor bundle. 3. A compressor according to claim 1, wherein a depression which is radially further outward than the inner circumferential wall surface is formed near the front end of the chamber; anda relative positional relationship between the roller and the depression is set such that, in a state in which the compressor bundle is completely accommodated and positioned in the chamber, the roller is positioned over the area of the depression, thus breaking the contact between the roller and the bundle casing. 4. A compressor according to claim 2, wherein at least an outer circumferential portion of the roller is formed of a copper-based material. 5. A compressor according to claim 4, wherein peening treatment is applied to at least the outer circumferential portion of the roller. 6. A compressor according to claim 1, wherein an adhesively mounted small tilt sensor is employed as the relative angle difference detecting means. 7. A compressor according to claim 3, wherein at least the outer circumferential portion of the roller is formed of a copper-based material. 8. A compressor according to claim 7, wherein peening treatment is applied to at least the outer circumferential portion of the roller. 9. A method of assembling a compressor, wherein, when inserting the compressor bundle of the compressor according to claim 1 into the chamber of the bundle casing, the method comprises: inserting the front end of the compressor bundle into the chamber;detecting a relative angle difference of the compressor bundle with respect to the bundle casing with the relative angle difference detecting means; andinserting the compressor bundle into the chamber while correcting a tilt angle thereof so that the relative angle difference falls within an angular range that makes it possible to insert the compressor bundle into the chamber without interfering with an inner circumferential wall surface of the chamber.
