| 摘要 |
The invention relates to a pedestal for load cells (5) comprising a force transfer screw (1) and a base plate (2), wherein the force transfer screw (1) is joined to the load cell (5) by means of an upper hinge (3) and to the base plate (2) by means of a lower hinge (4). The invention is characterized in that the upper hinge (3) is made of a bearing sleeve (6) inserted in the load cell (5) having an inner bearing cup (7) in which the force transfer screw (1) is supported at the upper spherical force input surface (8) thereof. The lower hinge (4) is made of a planar hole (9) made in the base plate (2), in which the force transfer screw (1) is supported by the convex force receiving surface (10) thereof. The radius of the convex force transfer surface (10) thereby corresponds approximately to the length of the force transfer screw (1) while the radius of the spherical force input surface (8) is a fraction, and maximally one-fifth, of the radius of the force transfer surface (10). |
