本発明は、負荷受容体のための平行案内装置
と、伝達レバーと、負荷受容体と伝達レバーとの
間において垂直な力を伝達するための連結部材と
を有している電子ばかりに関する。DETAILED DESCRIPTION OF THE INVENTION The invention comprises a parallel guide device for a load receptor, a transmission lever and a coupling member for transmitting vertical forces between the load receptor and the transmission lever. It's all about electrons.

とがある。 This type of scale is described, for example, in German Patent No. 2621483 or German Utility Model No.
It is known from specification No. 8008791. In these scales, a thin strip (German Utility Model No. 8008791) or a reduced cross-section formed by stamping, stamping or etching is used as the connection element between the load receptor and the transmission lever. Strips (German Patent No. 2,621,483) are used which are provided with one or several sections.
However, these components are extremely difficult to handle and assemble. In this case, even a very small deviation of the connecting element from planarity or from the parallelism of the assembly planes causes the connecting element to be tensioned during assembly. This, for example, causes a change in the point of application of the effective force depending on the load, so that the effective lever arm of the transmission lever changes independently of the load. However, even if the strip-shaped connecting member is flat and the assembly planes are parallel, the connecting member will be strained during assembly by the torque of the fixing screw and, in extreme cases, may be crushed.
ゆえに本発明の課題は、従来の電子ばかりにお
ける連結部材の上述の欠点を回避して特に、問題
なく組立てることができかつ組立てられた状態に
おいて良好に再現可能な力伝達を行なうことので
きる連結部材を提供することである。 It is therefore an object of the present invention to provide a coupling element which avoids the above-mentioned disadvantages of coupling elements in conventional electronic balances and which, in particular, can be assembled without problems and which provides a good and reproducible force transmission in the assembled state. The goal is to provide the following.
この課題を解決するために本発明の構成では、
連結部材が丸棒から成つていて、該丸棒が両端部
の近くに同様に円形横断面を備えた減径部を１つ
ずつ有しているようにした。 In order to solve this problem, in the configuration of the present invention,
The connecting element consists of a round bar, which has a reduced diameter near each end, likewise with a circular cross section.
２つの減径部によつて規定された２つの撓み箇
所が生ぜしめられ、これによつて、組立て面の平
行性からの僅かな偏位は補償され得る。連結部材
が一貫して円形の横断面を有していることによつ
て、連結部材の平面性はもはや問題なくなる。円
形横断面を有する連結部材は純然たる旋削部材な
のでその製作も簡単である。 Two flexure points defined by the two diameter reductions are created, by means of which small deviations from the parallelism of the assembly planes can be compensated. Due to the consistently circular cross-section of the connecting element, the flatness of the connecting element is no longer a problem. Since the coupling part with a circular cross section is a purely turned part, its manufacture is also simple.
連結部材の減径部の範囲における直径が他の範
囲における直径の約1/6であると有利である。こ

つていると、切欠き効果を回避することができ
る。 Advantageously, the diameter of the connecting element in the area of the reduced diameter is approximately 1/6 of the diameter in the other areas. With this setting, sufficient rigidity of the connecting member between the two reduced diameter portions can be obtained without significantly increasing the mass of the connecting member. It is also advantageous if the transition from the full-diameter part of the connecting element to the reduced-diameter part takes place gradually, so that notch effects can be avoided.

の位置に固定され、組立て時において固定ねじの
トルクによる緊張が連結部材に伝達されることは
なくなる。 Advantageously, the ends of the connecting element are clamped between the prismatic groove and the flat plate. As a result, the connecting member is fixed in a predetermined position without being displaced, and tension due to the torque of the fixing screw is not transmitted to the connecting member during assembly.
はかりの運動学に基づいて通常特に連結部材

ゆえにこの伝達レバー側の減径部が細つかつ／又
は長く構成されていると有利である。このように
構成されていると、この減径部の曲げ剛性は、負
荷受容体の側に位置している減径部の曲げ剛性よ
りも僅かになる。 Due to the kinematics of the scale, the reduced diameter part of the coupling element on the transmission lever side is usually subjected to bending loads.
Therefore, it is advantageous if the reduced diameter portion on the transmission lever side is designed to be narrow and/or long. With this embodiment, the bending stiffness of this reduced diameter section is lower than the bending stiffness of the reduced diameter section located on the side of the load receptor.

応力の発生時にも回避することができる。 In order to protect the reduced diameter part of the connecting part particularly well, a further advantageous embodiment of the invention provides for the connecting part to be surrounded in the region of the reduced diameter part by a protective tube, which on one side It is fixed to the connecting element on one side over the entire diameter of the connecting element, and on the other side it is somewhat enlarged and surrounds the connecting element at a small distance over the entire diameter. This makes it possible to avoid extremely strong bending forces being applied to the protective tube at the thin diameter-reduced portion, both during the manufacture of the scale and when buckling stress occurs in the connecting member in the assembled scale.

いないと有利である。 A connecting member with a circular cross section has an equal bending stiffness in all directions. However, if a further reduction in the bending stiffness in one direction subjected to bending loads during weighing is required in very sensitive instruments, the material on the sides located opposite each other in the area of the reduced diameter It is advantageous if a small area is additionally formed by removal, for example by grinding, and that this area has only a low bending stiffness in the direction in which it is subjected to bending stress during metering.

図示されていない。 The electronic balance shown in FIG. 1 has a support part 1 which is immovable relative to the housing and has two guide rods 4, 5 with flexure points 6.
The load receptor 2 is fixed movably in the vertical direction via. In its upper part, the load receiver 2 has a load pan 3 for receiving the object to be weighed and transmits a force corresponding to the mass of the object via the coupling member 9 to the short lever arm of the transmission lever 7. The transmission lever 7 is supported on the support part 1 by a cross spring hinge 8. A balancing force acts on the long lever arm of the transmission lever 7. In the illustrated embodiment, this balancing force consists of a coil 11 and a permanent magnet system 10 for producing an electromagnetic balancing force.
It is shown as. The associated electronic control unit is not shown because it is well known and is irrelevant to the subject matter of the invention.

周知なので、ここに詳しく述べることは省く。 Instead of an electromagnetic balancing force, the balancing force can also be generated, for example, by a spring element. In this case, the deflection of the spring member from the strain gauge is detected and converted into an electrical signal. This format is also well known, so we will not discuss it in detail here.

の約1/6に選択されていると有利である。 The connecting member 9 has a reduced diameter section 1 with a circular cross section.
It consists of a round bar with one bar 2 and 13 near the top and bottom ends. Both reduced diameter parts 12,1
3 produces in each case an area with a slight bending stiffness, which is the actual flexing point of the connecting member 9. FIG. 2 shows an enlarged side view of the upper part of the coupling member 9. The round bar has a region with a full diameter in its upper part, by means of which it is clamped onto the transmission lever 7. A transition area 14 follows the area having the full diameter of the upper part of the round bar, and this transition area 1
4, the diameter is gradually decreasing. This transition region is followed by a region of reduced diameter 12 which has an at least approximately constant slight diameter. Then the second
In the transition region 15 of the diagram, the diameter increases again gradually to the total diameter of the round bar. The lower diameter reduction 13, which is not shown in FIG. 2, is also designed accordingly. The dimensions of the connecting member 9 and the reduced diameter portions 12, 13 are set according to the size, maximum load, and degree of analysis of the scale.
In this case, the coupling element 9 must be as strong as possible, on the one hand, in order to simplify handling during assembly and in order to be able to transmit even large forces, for example in the event of an impact, without damage. is desired. On the other hand, however, the coupling element 9 is designed as far as possible in such a way that, in the event of bending due to component errors or in the event of deviations of the movable parts of the scale from the desired swivel position, as little reaction force as possible is transmitted to the weighing system. It is desired that it be easy to bend. As a compromise between these conflicting requirements, it is advantageous if the diameter in the area of the reduced diameter portions 12, 13 of the connecting element 9 is selected to be approximately 1/6 of the diameter in the other area of the connecting element 9.

参照）。もちろんこの効果は下側の減径部１３に
対して上側の減径部１２の直径を僅かにすること
によつても達成され得る。 In a scale with the arrangement shown in FIG. 1, in which the connecting member 9 acts on a very short lever arm of the transmission lever 7, the upper reduced diameter section 12 is subjected to bending loads in particular when the movable part of the scale is deflected. Ru. It is therefore advantageous if this upper reduced diameter section 12 is selected to be somewhat longer than the lower reduced diameter section 13 (see FIG. 1). Of course, this effect can also be achieved by making the diameter of the upper reduced diameter section 12 smaller than that of the lower diameter reduced section 13.

伝達されることはない。 The manner in which the connecting member 9 is tightened in the transmission lever 7 is shown in FIG. The transmission lever 7 is provided with a prismatic groove 17, in which the coupling member 9 is placed during assembly and is thereby fixed laterally. A flat plate 16 is then placed and tightened with two screws 18 near the sides of the connecting member 9. According to such a fixing method, no torque is transmitted to the connecting member 9 during assembly.

い曲げ応力が回避される。 FIG. 3 shows an embodiment of the connecting element 9 with an additional protective tube 20. In FIG. In FIG. 3, the area of the upper reduced diameter section 12 is shown in an enlarged sectional view.
The protective tube 20 is fixed at one end 21 to the connecting member 9, for example by adhesive or laser welding. The protective tube 20 extends from this fixing point beyond the area of the reduced diameter section 12 to a region 22 in which the connecting element 9 again has its full diameter. This range 22
In this case, the protective tube 20 is somewhat enlarged, so that a small annular gap is created between the connecting member 9 and the protective tube 20. This configuration avoids extremely strong bending stresses in the region of the reduced diameter portion of the connecting member 9, without impeding the freedom of movement for slight bends that occur during normal weighing operations. Ru.

For this purpose, for example, the load receptor 2 can have horizontal ribs with vertical holes, through which the connecting element 9 is guided.

In this case, in addition to the reduced diameter part 12 with a circular cross section, small areas 19 are provided by grinding at mutually opposite positions (see FIG. 4), which areas 19 are shown in FIG. no longer has a circular cross section as shown in . Configured in this way, the reduced diameter section 12 has a particularly low bending stiffness in the direction defined by the chamfer. This again makes the handling of the connecting element 9 difficult, but if a slight bending stiffness of the connecting element 9 is highly desired, the best compromise between the above-mentioned conflicting requirements for the connecting element 9 is found. It is.
