BEARING FOR PLATFORM SCALE

摘要

In a platform scale in which the strain gage transducer beams are preferably formed as an integral part of a platform it is important that any distortions such as horizontal or angular force components that could falsify the reading of the weight, are prevented from affecting the transducers. For this purpose, the vertical load or weight representing force components are transmitted to each strain gage transducer beam through at least two cooperating curved, preferably spherical, surfaces. One curved surface has a larger curvature than the other so that a sufficient motion in any horizontal direction is permitted. The horizontal yielding prevents the transmission of a horizontal or angular force component to the sensing strain gages of the respective transducer beam but does not adversely affect the vertical force transmission to the transducer beams.
