本考案はポテンションメーターとシンクロメーターとか
らなるサーボ式指示計の連動機構に関する。[Detailed Description of the Invention] The present invention relates to an interlocking mechanism for a servo indicator consisting of a potentiometer and a synchrometer.

あったが、然しこのような連動機構によるときは、
（１）ギヤーのバックラッシュにより精度が高められな
い。In conventional servo-type indicators, as shown in Figure 3 of the attached drawings, the interlocking transmission between potentiometer a and synchro motor b was normally carried out via gear box C; When using a similar interlocking mechanism, (1) Accuracy cannot be improved due to gear backlash.
（２）制御系のコントロールが不可能になった場合に過
度に回転させられて指針の折損故障等が起る。(2) If the control system becomes uncontrollable, the pointer may be rotated excessively and the pointer may break or malfunction.
（３）モーター、ギヤーボックス、ポテンションの組立

指示精度を更に高めることができる新規な考案を提供し
ようとするものである。In view of the disadvantages of the conventional servo indicator as described above, the present invention has a potentiometer and a synchro motor installed side by side, and the pointer shaft of the former and the drive shaft of the latter are connected by a pulley and a belt. , and by tensile support of the belt in the winding direction, the mechanism is simpler than that of a conventional mechanism with a gear box interposed, and the present invention provides a novel device that can further improve the accuracy of the indication. That is.

いる。An embodiment of the present invention will be described below with reference to the figures in Figs. 1 and 2. As shown in Fig. 1, a potentiometer 3 is mounted on the bottom plate 2 of the indicator body 1 of the present invention on a mounting base 3'. A synchronized motor 4 is fixed to the upper part, and a synchronized motor 4 is supported on one side by a leaf spring 4' having an elastic force.

る。A pointer pulley 5' and a pointer 5'' facing above the scale plate 6 are fixed coaxially to the pointer shaft 5 of the potentiometer 3, and a drive pulley 7' is fixed to the drive shaft 7 of the synchro motor 4. An interlocking belt 8 is wound between the interlocking pulley 5' and the driving pulley 7' under tension in the winding direction by the leaf spring 4'.

示値を指示する。The operation of the present invention having the above-mentioned configuration is as follows: First, the synchro motor 3 is rotated by a signal from a control system (not shown), and the rotation is caused by a point from the interlocking belt 8 that is wound around the drive pulley 7' of the drive shaft 7. The information is transmitted in an interlocking manner to an interlocking Booneau 5' fixed to one side of the pointer shaft 5 of the tension meter 3, and the pointer 5'' coaxial therewith and facing onto the scale plate 6 indicates each indicated value.

位置ずれは適切に防止されるのである。The rotation of the potentiometer 3 directly connected to the above-mentioned pointer shaft 5 is sequentially fed back to the control system, and
The interlocking rotation of the potentiometer 3 and the synchro motor 4 is achieved by the motor 4 being resiliently supported in the direction of the arrow shown in FIG. Interlocking belt 8 wrapped around
The winding rack is appropriately tensioned in the direction of the winding rack, and the positional shift of the winding rack is appropriately prevented.

ある等の各効果を有するものである。When using the configuration and operation of the present invention as in the case of the diagonal top, since gears are not used to connect the potentiometer and the synchro motor, the accuracy of indication is increased, and the pulleys and belt winding racks can be adjusted as appropriate. Because it is a flexible tension, the pointer will not break even if the control system becomes uncontrollable, and it has various effects such as being easy to manufacture and assemble, and being inexpensive. .
