Installation/removal device for one or more rotor blocks of a turbocharger assembly, and method

A method for simultaneously inserting at least two rotor blocks into a housing of a multi-stage turbocharger assembly by means of an installation/removal device comprising

• a support element having first guide rails, which are arranged on a first longitudinal side of the support element, and second guide rails, which are arranged on a second longitudinal side of the support element;
• a movement device having:
• a first slide, which is arranged so as to be movable on the first guide rails,
• a second slide, which is arranged so as to be movable on the second guide rails,
• a spindle, which is rotatably mounted in the support element, and
• a connection element, which is connected to the spindle, to at least one of the first slide and the second slide, wherein the connection element is configured to convert a rotary movement of the spindle into a translational movement of at least one of the first slide and the second slide;
• and
• a fastening device, which has a first fastening structure for fastening a first rotor block and a second fastening structure for fastening a second rotor block;
• wherein the first fastening structure is connected to the first slide, and the second fastening structure is connected to the second slide,
• the method comprising:
• installing in each case at least one guide element per rotor block of the turbocharger assembly, wherein the at least one guide element is arranged and configured to guide the rotor blocks along the axis of rotation of the rotor blocks as they are moved in,
• connecting the at least two rotor blocks by means of a rigid fastening element;
• fastening a first fastening structure of an installation/removal device to a first rotor block;
• fastening a second fastening structure of an installation/removal device to a second rotor block;
• moving the at least two rotor blocks into the housing of the multi-stage turbocharger assembly.

A method for pulling out/inserting one or more rotor blocks from/into a housing of a single- or multi-stage turbocharger assembly by means of an installation/removal device comprising:

• a support element having first guide rails, which are arranged on a first longitudinal side of the support element, and second guide rails, which are arranged on a second longitudinal side of the support element;
• a movement device having:
• a first slide, which is arranged so as to be movable on the first guide rails,
• a second slide, which is arranged so as to be movable on the second guide rails,
• a spindle, which is rotatably mounted in the support element, and
• a connection element, which is connected to the spindle, to at least one of the first slide and the second slide, wherein the connection element is configured to convert a rotary movement of the spindle into a translational movement of at least one of the first slide and the second slide;
• and
• a fastening device, which has a first fastening structure for fastening a first rotor block and a second fastening structure for fastening a second rotor block;
• wherein the first fastening structure is connected to the first slide, and the second fastening structure is connected to the second slide,
• the method comprising:
• installing in each case at least one guide element per rotor block of the turbocharger assembly, wherein the guide elements are arranged and configured to guide the rotor blocks along the axis of rotation of the rotor blocks as they are moved out/moved in,
• fastening a support element of the installation/removal device to the housing of the single- or multi-stage turbocharger assembly;
• fastening at least one of a first fastening structure of the installation/removal device to a first rotor block;
• and a second fastening structure of the installation/removal device to a second rotor block;
• pulling out/inserting at least one of the first rotor block and the second rotor block by moving at least one of the first fastening structure and the second fastening structure relative to and along the support element.

A method for moving one or more rotor blocks, comprising

• fastening the one or more rotor blocks to a rigid fastening element;
• and
• moving the one or more rotor blocks, including an installation/removal device, while the one or more rotor blocks are fastened to the fastening element, the installation/removal device comprising:
• a support element having first guide rails, which are arranged on a first longitudinal side of the support element, and second guide rails, which are arranged on a second longitudinal side of the support element;
• a movement device having:
• a first slide, which is arranged so as to be movable on the first guide rails,
• a second slide, which is arranged so as to be movable on the second guide rails,
• a spindle, which is rotatably mounted in the support element, and
• a connection element, which is connected to the spindle, to at least one of the first slide and the second slide, wherein the connection element is configured to convert a rotary movement of the spindle into a translational movement of at least one of the first slide and the second slide;
• and
• a fastening device, which has a first fastening structure for fastening a first rotor block and a second fastening structure for fastening a second rotor block;
• wherein the first fastening structure is connected to the first slide, and the second fastening structure is connected to the second slide.
