Abstract

A device for measuring axial force in a shaft journalled or mounted with two roller bearings arranged side by side in a housing, such measuring occurring by means of wire strain gauges or the like. The inner ring of the roller bearing on the shaft side engages a shaft shoulder, and the end faces of the roller bodies of the roller body row facing the bearing cover are supported by the flangeless inner ring of the adjoining roller bearing against a flanged ring or angle ring which is disengageably arranged on the shaft. This device is especially intended for wheel-set shafts of rail vehicles during travelling operation. Those end faces of the roller bodies of the two roller body rows facing each other are supported on a central flanged ring which transfers force and is movable in the direction of force when force is applied. A gauge ring is located between the central flanged ring and those two end faces of the roller bearing rings located diametrically opposite each other, with a part of the gauge ring being arranged transverse to the shaft axis, being operatively connected with the central flanged ring, and being provided with wire strain gauges or the like. The gauge ring has a pa…
