Embodiment Construction

[0029] figure 1 The weighing system 11 shown in a perspective view in the figure includes a base area 1 fixed to the housing and a bearing seat 4, which is movable in the vertical direction in the form of parallel guide rails through an upper guide rod 5 and a lower guide rod 6 ground connection to the base area. Thin points of material that act as hinge points are marked with 9. The weight of the weighing item acting on the carrier 4, which for example is introduced at the hole 12, passes through a protrusion 8 and a figure 1 The coupling element 7 , which can only be partially seen in the figure, transmits to the short lever arm of a transmission lever 2 . The transmission lever 2 is pivotably mounted on a raised part 1 ′ of the base area 1 via a cross spring joint 3 . On the long lever arm 2' of transmission lever 2, it is fixed on figure 1 Invisible coils. The coil protrudes into the air gap of a permanent magnet system, not shown, which can be fastened to the base re...

Abstract

A weighing system having a base region ( 1 ), a parallel-guided load receiver ( 4 ), at least one transmission lever ( 2 ) that is pivotably mounted on the base region via at least one flexural pivot ( 3 ), and a coupling element ( 7 ) that connects the load sensor to the short lever arm of the transmission lever. The flexural pivot ( 3 ), at least one part of the transmission lever ( 2 ), and atleast one part of the base region ( 1' ) are monolithically formed from a block. The flexural pivot ( 3 ) is separated from the rest of the block by four horizontal parallel bores ( 31, 32, 33, 34 ) that are adjacently arranged in an annular manner in such a way as to respectively leave a thin connecting segment ( 36, 37, 38 39 ) between adjacent bores, and by additional slots. In this way, a hysteresis-free flexural pivot can be created without the need for separate assembly components.

Description

technical field [0001] The invention relates to a weighing system comprising: a base area; a parallel-guided bearing seat; at least one transmission lever, which is deflectably mounted on the base area via at least one cross spring joint; and a coupling element, which carries The seat is connected to the short lever arm of the transmission lever. Background technique [0002] Weighing systems of this type are generally known and are described, for example, in German utility model DE-Gbm 81 35 182 . [0003] The disadvantage of this known weighing system is that since the cross spring connection is formed by individual leaf springs, the assembly and adjustment are very expensive, and because the leaf springs are fixed on the transmission lever and on the base area It is possible to over-tension the cross spring joint, which may cause hysteresis, drift and poor long-term stability. [0004] In order to get rid of these problems, it is known, for example, from US 3 700 289 to...
