WEIGHING DEVICE Russian patent published in 1998 - IPC

FIELD: instrumentation engineering; weight measuring technology. SUBSTANCE: device has bed plate 1 and load-receiving platform 2 coupled to each other for reciprocal motion by means of rigid links 4 with connection assemblies 6 positioned at their ends, as well as force measuring system 3. Rigid links 4 are oriented to one side relative to connection assemblies 6 with bed plate 1. Connection assemblies 6 of rigid links 4 with bed plate 1 and load-receiving platform 2 are made as rotary kinematic pairs with one degree of freedom, on flexible flat members 5. Axes of rotation of respective kinematic pairs coincide. Axes of rotation of pairs adjacent to bed plate 1 and to load-receiving platform 2 are parallel to each other, and they are positioned in plane perpendicular to vector of force being measured. Number of rigid links 4 is at least one, and load- receiving platform 2 engages force inputs of force measuring system 3 by means of at least three kinematic pairs 7 with five degrees of freedom. EFFECT: higher measurement results. 5 dwg
