A method for measuring vibrations in which gravity forces and acceleration forces resulting from machine vibrations are measured using an accelerometer/inclinometer sensor coupled to a non-rotating part of a rotating machine, the orientation of the sensor with regard to the direction of action of the gravity forces is determined from a stationary component of sensor output, and non-stationary components of sensor output are evaluated based upon the determined sensor orientation. Both the result of the alignment process and also the result of the vibration measurement are communicated to the user as an easily understandable characteristic on a display of an evaluation unit.

Method for determining a quality characteristic and vibration measurement method

Method for determining a characteristic for the quality of alignment of a rotating machine, by obtaining vibration data with at least one vibration sensor, and using the vibration data obtained with the vibration sensor to determine a characteristic for the quality of alignment. Furthermore, alignment data obtained from first and second optoelectronic units is used in addition to the vibration data obtained with the at least one vibration sensor to produce a combination value from which both an instantaneous vibration state and success of the alignment can be determined.

Method for determining a quality characteristic and for vibration measurement

An alignment device with one or two optoelectronic transmitting and/or receiving units and an evaluation unit. At least one optoelectronic transmitting and/or receiving unit contains an inclinometer. Furthermore, the transmitting and/or receiving unit is connected to a vibration sensor which can be the inclinometer. Both the result of the alignment process and also the result of the vibration measurement are communicated to the user as an easily understandable characteristic on a display of the evaluation unit. For vibration measurement at a non-rotating part of a machine, an accelerometer/inclinometer sensor may be used for measuring acceleration forces resulting from machine vibrations to be measured and for measuring gravity and an electronic evaluation unit determining the orientation of the sensor with regard to gravity from a stationary component of the sensor output and determining sensor orientation from evaluation of non-stationary components of sensor output.

A rotating machine element is monitored for displacements using co-rotating sensors for acceleration, rotation or the direction of gravitation. In doing so, the sensor data are received by a, likewise, co-rotating electronic unit. The data can also be stored and further processed in this electronic unit.

An ergonomically equipped and interference signal-reducing position measurement probe for mutual alignment of bodies has a speech input device and/or a speech output device. The probe is wirelessly linked to an external control or a higher-level supervisory computer either by an infrared interface or a radio link which operates at an extremely high frequency. Error-reducing measured value acquisition is effected by averaging. The average represents several individual measured value. In the acquisition of the individual measured values, it is watched that the times of measured value recording and the time peaks of a solid-borne sound oscillation on the measurement object are essentially asynchronous to one another.

The invention relates to a process and device for determining the alignment, with respect to a reference direction, of a cylindrical body ( ) mounted to rotate around its lengthwise axis ( ). The device including a position measurement probe ( ), which is calibrated to the reference direction, being attached on the end face ( ) of the body or on a surface essentially parallel to the end face, which probe gathers measurement data in at least three measurement positions around the lengthwise axis each position of which differs from the other by an angle of rotation of the body, such that one position measurement at a time is being taken. Then the alignment of the body with respect to the reference direction is computed from the determined measurement data.

A device for precision measurement of shafts, spindles, or the like calls for two surfaces which are combined with one another, of which one is partially reflecting and the other is roughly fully reflecting. These surfaces reflect an incident light beam independently of one another onto a single optoelectronic target. The target can be read out two-dimensionally and is pixel-oriented. From only a single measurement position, the azimuth and elevation, and the parallel offset between the incident light beam and a center of the reflecting surfaces can be determined.

A device is proposed, which makes it possible to ascertain the relative position of the reference axis BA of an object relative to a reference beam R of an electromagnetic radiation, in particular a laser beam. The device displays a spatially fixed radiation transmitter S and&mdash;at the object end&mdash;a splitting mirror as well as two position detectors and . The splitting mirror branches a partial beam R off from the reference beam. The reference beam passing rectilinearly through the splitting mirror impinges on the one position detector and the partial beam on the other. The position detectors supply electrical signals, from which the position of the reference axis is ascertainable by means of a computer. The known devices of this species have an appreciable space requirement. This defect is eliminated by a particular structuring of the beam conduction and the additional use of special optical means. Beyond that, the measurement possibilities can be enlarged through additional emission of a second reference beam R .

A method and an apparatus are specified for alignment of the shaft W,of a rotating machine M,in a predetermined nominal position by moving the machine M,on the base, as well as an apparatus for carrying out the method. The instantaneous position of the shaft W,is detected in a known manner by a sensor device,which provides electrical position signals corresponding to the difference between the instantaneous position of the shaft W,and the shaft nominal position. These position signals, the known relative position of the mounting points,of the machine M,on the base with respect to the predetermined reference points on this base, and other geometric measurement data are used by a computer to calculate correction values for position corrections to be made at the individual mounting points,of the machine M,and these correction values are brought to the attention of the alignment technician,for the magnitude and direction for each mounting point,According to the invention, the current correction values which, until now, have been indicated only visually according to the prior art, are transmitted acoustically, for the individual mounting points,to the alignment technician,The alignment technician,can thus pay his full attention to the position corrections to be carried out at the mounting points (,).

The spatial position of rollers or other mutually adjacent articles is measured or examined by indirect transport of a reference direction. To this end, an adaptor is placed on one of the rollers. The adaptor is equipped with a light source which emits a light beam substantially parallel to the axis of rotation of a roller. The light beam is sensed by a movable sensor unit. The latter determines, at the same time, the angle of incidence of the light beam according to two axes, relative to the sensor unit, and the orientation of the sensor unit relative to a reference axis system (laboratory system). A multi-axially operating gyroscope is used for the last-mentioned measurement. A suitably programmed electronic system or computer determines, from the two measured values, the orientation of the adaptor and of the roller with respect to azimuth and elevation in the laboratory system. The measured values which are determined can be utilized for the purpose of making a comparison with the corresponding values of further rollers or articles, so that an apparatus for parallelism measurements which is easy to handle is provided.
