Abstract

Provided is an apparatus capable of transporting a rotor from a first location to a second location, including: a holding device for engaging with a portion of the rotor at the first location so as to hold the rotor relative to the apparatus; a position determination device for determining the position of at least one component part of the rotor relative to another component part of the rotor or another body; a positioning device for positioning or repositioning said at least one component part of the rotor relative to another component part of the rotor or another body; and a movement device for moving the rotor from the first location to the second location. Also described is a method of loading a rotor into a balancing machine.

Claims

1. A method of loading an elongate rotor into a balancing machine, the rotor including an elongate portion which is rotatable about an elongate axis and at least one part which is articulated relative to the elongate portion, the method comprising:

obtaining a balancing machine comprising;

a first mounting apparatus capable of engaging with and holding a first respective ends of the rotor;

a second mounting apparatus capable of engaging with and holding a second respective end of the rotor; and

a motor for driving one or both of the first and second mounting apparatus,

collecting a rotor from a first location using a transporting apparatus, the transporting apparatus including;

a first holding device capable of engaging with the elongate portion of the rotor so as to hold the elongate portion of the rotor relative to the transporting apparatus;

a second holding device capable of engaging with said at least one articulated part of the rotor so as to hold the at least one articulated part of the rotor relative to the transporting apparatus; and

at least one positioning device capable of moving axially to a desired axial position to ensure that the at least one positioning device does not foul the at least one articulated part, the positioning device also being capable of engaging with the at least one articulated part of the rotor,

using the at least one positioning device to engage with and hold the at least one articulated part in a desired axial position relative to the elongate portion of the rotor and also position said at least one articulated part of the rotor so that the at least one articulated part lies in a plane which is substantially perpendicular to the elongate axis of the elongate portion of the rotor to ensure that the at least one articulated part can be engaged with either of the first and second mounting apparatus of the balancing machine;

loading the rotor into the balancing machine; and

engaging the first and second mounting apparatus of the balancing machine with a respective end of the rotor.

2. The method according to claim 1 comprising the steps of:

determining the position of two component parts of the rotor relative to one or more other component part of the rotor or another body;

and wherein, prior to or at the same time as the step of loading the rotor into the balancing machine, the method includes one or both of the steps of;

positioning or repositioning said two component parts of the rotor relative to their respective other component part of the rotor or their respective another body; and

/or

positioning or repositioning both the first and second mounting apparatus of the balancing machine at desired positions which corresponds to the position of the two component parts of the rotor.

3. The method according to claim 1 wherein the component part of the rotor is an endmost part thereof.

4. The method according to claim 1 wherein the method comprises the steps of:

determining the position of a first endmost part of the rotor;

determining the position of a second, opposite, endmost part of the rotor;

positioning or repositioning the first mounting apparatus of the balancing machine at a desired position which corresponds to the position of the first endmost part of the rotor;

positioning or repositioning the second mounting apparatus of the balancing machine at a desired position which corresponds to the position of the second endmost part of the rotor;

loading the rotor into the balancing machine; and

engaging the first and second mounting apparatus of the balancing machine with respective endmost parts of the rotor.

5. The method according to claim 4 wherein the method comprises the steps of:

determining the position of a first endmost part of the rotor;

determining the position of a second, opposite, endmost part of the rotor;

positioning or repositioning the first mounting apparatus of the balancing machine at a desired position which corresponds to the position of the first endmost part of the rotor;

loading the rotor into the balancing machine;

engaging the first mounting apparatus of the balancing machine with the first endmost part of the rotor;

rotating the rotor until the second endmost part is aligned with the second mounting apparatus; and

engaging the second mounting apparatus of the balancing machine with second endmost part of the rotor.

6. The method according to claim 5 wherein the rotor is rotated by a positioning device or holding device on the transporting apparatus.

7. The method according to claim 6 wherein the rotor is rotated by driving the first mounting apparatus.

8. The method according to claim 1 wherein the position determined is the angular and/or axial position of the first and second endmost parts of the rotor.
