摘要： 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 alpha 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 alpha , 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.

摘要： The invention relates to a coupling device for connecting a first shaft (10) to a second shaft (12) by means of two flanges (16, 18, 22, 24) that are meshed with one another, wherein the flanges are provided or designed with means (30, 32, 111, 211, 311, 317, 319, 321) of enabling the axial and/or radial relative adjustment thereof due to a misalignment of the shafts to be visually observed. According to one variant, at least one of the flanges or an element (20, 26) meshed with the two flanges is provided with at least one converter (50, 60, 70, 80, 90; 94) for generating an electrical signal and/or acoustic signal from a mechanical movement, wherein said converter is designed to generate the signal on the basis of a periodic movement of the flanges relative to one another, at least if the relative movement of the two shafts to one another, which occurs as the shafts rotate due to a misalignment of said shafts, exceeds a certain value.

摘要： The invention relates to an electro-optical measuring device for determining the relative position of two bodies (2, 3) or of surfaces areas of bodies, to each other comprising, in a known manner, a light-beam emitter (4) emitting a focused light beam (L) which can be applied to the one body (3) or surface area, and an opto-electronic position detector having one or several axes and fitted with a light-sensitive measuring surface (5). When the bodies (2, 3) or surface areas are being measured, the light beam (L) impinges on the measuring surface (5) and its point of impingement (LA), in carrying out a measuring movement, moves across the light-sensitive surface (5) in a manner characteristic of the current position the bodies (2, 3) or surface areas have in relation to each other. When the bodies' relative position to each other deviates substantially from a desired target position, it can happen with known measuring devices of this type that, without corrective measures, the point of impingement (LA) of the light beam leaves the measuring surface (5) as the measuring movement continues. According to the invention, this is prevented by means of a device which monitors the measuring movement and enlarges the field of measurement.

摘要： The invention relates to an opto-electronic sensor arrangement for determining the rotation speed and relative position of rotating devices. The process is distinguished in that, by means of a differential photodiode and a special storage process for the measured contrasts, two maximum contrasts on the surface of the rotating body in opposite directions -- rotation and counter-rotation -- are found and used as measuring marks.

摘要： The proposal is for a device for measuring acceleration via piezoelectric transducers. The device has a prior art bearer (14, 16) with a parallel main shaft for acceleration measurement, a seismic mass (20, 22) held so as to move in relation to the bearer and piezoelectric units (12, 12') acting in pairs and connected so as to be excited, in which the arrangement is such that pyroelectric effects are compensated. According to the invention, the bearer has a cross-member (16) extending transversely to the main shaft and the piezoelectric units excited by compression are fitted thereon on its opposite sides in relation to the direction of the main shaft between the latter and the seismic mass (20, 22). This results in temperature-independence and insensitivity to ground expansion and acceleration of any other kind and direction than linear and parallel to the main shaft.

摘要： Device for determining modifications of the mutual position of two machines or parts of machines which are separately mounted at a certain distance from each other with respect to a given starting position in a right angle spatial coordinate system. Thereby, a high operation efficiency and a high measuring precision together with low construction costs and a reduced sensitivity to perturbations, as well as a direct perceptibility of orientation errors with respect to the parallel displacement and the angular displacement are obtained. This is effected by using an orthogonal reflector prism and a light emitter for each of the three axial directions of the coordinate system where a neutral parallel and angular displacement is to be observed, the reflector prisms and the light emitters being mutually fixed to the machines, respectively to the machine parts.
