Abstract
Official abstract text for this publication.
A method for measuring and adjusting gaps between a rotor and a stator of a machine using a sensor is provided. The measuring is conducted when the rotor is operated at a rotational speed below a nominal rotational speed of the machine and without the machine being in operation. The adjusting of the gap is carried out as a function of at least one gap dimension of the gap. The sensor is not resistant to an operating temperature of the machine occurring in a region where the sensor is located. After completion of the measuring the machine is operated with the sensor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for measuring and adjusting gaps between a rotor and a stator of a machine, comprising: providing a sensor; measuring a gap between the rotor and the stator using the sensor, wherein the measuring is conducted when the rotor is operated at a rotational speed below a nominal rotational speed of the machine and without the machine being in operation; and adjusting the gap, wherein the adjusting of the gap is carried out as a function of at l…
