Abstract
A beamless dynamometer or weighing machine has a work coil positioned in a working air gap of a magnet arrangement. A pair of elastic links of trapezoid-shaped construction are attached to a bracing part. The median axis of the work coil is arranged within a trapezoid bounded by arms and sides of the links. The magnet arrangement is positioned in space bounded by the links.
Claims22
In an electromagnetically compensating beamless dynamometer or weighing machine having a work coil movable along its median axis in a working air gap of a stationary magnet arrangement with a principal portion, a parallel construction with two elastic links which are arranged in planes staggered in a direction of movement and are connected to a bracing part maintained stationary and to a rigid connecting element movable with the work coil so as to form a parallelogram the improvement wherein each of said links is defined by two arms of equal length staggered in a respective plane, each of said links being of trapezoid-shaped construction defined by its respective two arms and being attached by mutually farther ends of their respective arms to said bracing part, said median axis of said work coil being arranged within a trapezoid bounded by said arms and parallel connecting sides of said links at right angles to surfaces of said trapezoid and said principal portion of said magnet arrangement being arranged in space bounded by said links.
