摘要:
The invention concerns a method of mutually aligning bodies, in particular for the parallel alignment of shafts, rollers and the like, which can be carried out economically and simply in a substantially shorter time than the known methods used for this purpose. The essence of the invention is the use of an optical gyroscope, for example a fibre-optic gyroscope (5), in a position-measuring sensor (4) which is placed in turn in a specific position on the bodies (1, 2, 3) to be mutually aligned for a given time interval to measure the relative angular position. The position-measuring sensor (4) supplies angle data on the basis of which it can be established whether, and if necessary which, position corrections have to be made at the bodies in order to bring them into the desired state of alignment. The invention further concerns a position-measuring sensor which can be used in the method according to the invention.

A device for ascertaining misalignments of two shafts (1, 2) arranged one behind the other has a light emitter (6) rigidly fixed on one shaft (1) and which transmits in a manner known per se an alignment measurement beam (F) onto a detector surface (8a) of an optoelectronic position detector (8). According to the invention, the position detector (8) has another detector surface (8b) located next to the first detector surface (8a) and parallel thereto, and in front of which is mounted an optical inclinometer (9) to ascertain the momentary angle α of a predetermined radial reference direction of the shaft with respect to the earth perpendicular. The optical inclinometer (9) transmits the angle information as an angle-dependent position of a light spot on said second detector surface (8b). The angle α, which is often required to evaluate the alignment measurement signals and for other purposes, and which has a predetermined radial reference orientation of the shafts with respect to the earth perpendicular, can thus be measured with minimum additional space requirements and in a particularly favourable manner as regards the wiring technology.

The proposal is for a process and device making it possible to determine the condition of one or more machines (3) at several measuring points by means of a measuring head (MK) with measurement transducers (MW) which can be releasably fitted there and to supply to a computer the relevant measurement signal together with the characteristic data therefor obtained at the measuring point concerned. The invention lies in the special nature of the obtaining of the characteristic data. For this purpose there are at each measuring point special coding elements (5) adjustable between two possible operating states which work together with an allocated contact device (K, K') in the attached measuring head (MK) and, depending on the set operating state, permanently affect it or leave it unaffected, from which a characteristic electric signal is generated in the measuring head (MK) for each contact device (K, K') which, depending on the operative position of the appropriate coding element (5), has one or other of two different possible values. The individual electric signals generated for each coding element are then fed into the computer in parallel or series as the characteristic signal of the relevant measuring point.

A process for verifying the parallelism of axes of bodies can be carried out simply using low-cost auxiliary apparatus while still yielding highly accurate results. In the process, a measurement beam (L), preferably a laser beam, is emitted perpendicular to the axis of each body (1, 2). When said beams are rotated in succession about the axis of the bodies, they fall on at least three detectors (4a, 4b, 4c, 4d, 4e). Each detector then emits a signal indicating the position of the point of coincidence on a detector axis (5) of the corresponding detector. The spatial position of the axis of each body relative to a reference axis is calculated from the detector signals and the relative position, which may be measured separately, of points of intersection of the body axes and the detector axes with a surface defined by a measurement beam. A device which is particularly suitable for carrying out the process is also indicated.
