本考案は例えば電気転てつ機のポイント転換
力、フリクシヨンクラツチの回転伝達力等を測定
するために用いられるトルク記録装置に関する。[Detailed Description of the Invention] <Technical Field> The present invention relates to a torque recording device used to measure, for example, the point switching force of an electric point machine, the rotation transmission force of a friction clutch, etc.
〈従来技術〉
従来のトルク記録装置は第１図に示したよう

２ａ又は２ｂとアーム４との相対変位分記録紙上
を移動する構成となつていた。尚、６はハンドル
である。<Prior Art> As shown in FIG. 1, a conventional torque recording device has two spring cases 2 on a measuring shaft 1 that is fitted into a hole for inserting a manual handle of an electric point machine, for example.
a, 2b and the spring cases 2a, 2
An arm 4 formed with advancing/retracting rods 3a, 3b that moves back and forth in b is rotatably mounted, and springs 5a, 5b having the same spring constant are interposed between the advancing/retracting rods 3a, 3b and spring cases 2a, 2b, Spring case 2a
Alternatively, a recording pen (not shown) is connected to the spring case 2b and the arm 4 by a link mechanism, and the recording pen is moved on the recording paper by the relative displacement between the spring case 2a or 2b and the arm 4. Note that 6 is a handle.
ところが、従来のトルク記録装置にあつては、
スプリング５ａ，５ｂが線形バネであるため、低
トルク領域の検出能を高めるとトルク検出領域幅
が狭くなるし、トルク検出領域幅を拡大すると低
トルク領域の検出能が低下するジレンマがあつ
た。 However, with conventional torque recording devices,
Since the springs 5a and 5b are linear springs, there was a dilemma in that increasing the detection capability in the low torque region would narrow the torque detection region width, and enlarging the torque detection region width would reduce the detection capability in the low torque region.
また、スプリング５ａ，５ｂは単にバネケース
２ａ，２ｂ内に介装されただけであるから、圧縮
力しか伝達できず、このため右廻りのトルクと左
廻りのトルクの夫々に対して別々のスプリングを
必要とし、更に、夫々のスプリングに対してもバ
ネケースを必要とする等無駄の多いものであつ
た。 Furthermore, since the springs 5a and 5b are simply interposed within the spring cases 2a and 2b, they can only transmit compressive force, and therefore separate springs are used for clockwise torque and counterclockwise torque, respectively. Further, each spring requires a spring case, which is wasteful.

ク記録装置を提供することを目的とする。<Purpose of the invention> The present invention was devised in view of the above points, and can be used for both clockwise and counterclockwise torques, and moreover,
By arranging multiple springs with different coil natural lengths in parallel so that the spring force of the shorter springs acts as the amount of displacement increases,
It is an object of the present invention to provide a torque recording device that is compact and configured to achieve both detection capability in a low torque region and expansion of the torque detection region.

形成している。 In the figure, a measuring shaft 11 that is inserted and fitted into a manual handle insertion hole of, for example, an electric point machine has an arm 13 having a handle 12 formed at one end.
is rotatably attached, and furthermore, a spring case 14 is fixed via a frame 15.
An interlocking member 17 that moves forward and backward within the spring case 14 while being supported by a bearing 16 is linked to the arm 13 . Locking pieces 19 and 20 are fixed to this interlocking member 17 to be appropriately locked and moved by spring receivers to be described later. In addition, springs 21 and 22 having different natural lengths are provided in the spring case 14.
are arranged, and one end of them is connected to the spring case 1.
The other end of the spring 21, which has a long natural length and is disposed on the outside, contacts the spring receiver 24 whose movement is restricted by the stopper part 23 of the spring case 14 or is moved by being pressed by the locking piece 19. The other end of the spring 22, which has a short natural length and is disposed on the inside, is spaced at a predetermined interval. When the interlocking member 17 moves beyond the predetermined distance, it comes into contact with a spring receiver 27 fixed to the spring receiver 26 . That is,
These configurations form a hard spring non-linear spring.

列構成となり、バネ定数が中途から不連続的に大
きくなる。 The measuring shaft 11 is inserted, for example, into a handwheel insertion hole of an electric point machine, and the handle 12 is rotated in the direction of arrow A. Because the interlocking member 17 moves in the direction of arrow C via the arm 13 due to this rotation,
One end of the spring 21 is regulated by a stopper part 23, and is compressed by a spring receiver 26 that moves under pressure from a locking piece 20, and moves toward the measuring shaft 11 via the spring case 14 and frame 15 as shown by the arrow A.
Apply directional torque. Then, when the handle 12 is further rotated in the direction of arrow A, the spring receiver 27
comes into contact with the spring 22 and begins to compress the spring 22, so the springs 21 and 22 are arranged in parallel, and the spring constant increases discontinuously from the middle.

Ｔ＝Ｌ・K1・Ｘとなる。 On the other hand, the recording pen 30 has an arm 13 and a frame 1.
5 via a link mechanism, and is configured to move horizontally on the recording paper 29 of the drum 28 section in an amount equal to the amount of change in the relative distance between the arm 13 and the frame 15. The amount of displacement is recorded. Therefore, the spring receiver 27
2, the torque T applied to the measuring shaft 11 becomes T=L·K 1 ·X.

までの変位量である。 Here, L is the distance from the center of the measurement axis 11 to the line of action of the force, K 1 is the spring constant of the spring 21,
X is the amount of displacement. Furthermore, at a displacement greater than the amount at which the spring receiver 27 comes into contact with the spring 22, the torque T applied to the measuring shaft 11 is T=L・(K 1 +K 2 )・(X−X 0 )+L・K 1・X 0 Become. Here, K 2 is the spring constant of the spring 22,
X 0 is the amount of displacement until the spring receiver 27 comes into contact with the spring 22.

, and is compressed by the spring receiver 24 which is moved by being pressed by the locking piece 19, and thereafter performs the same operation as when rotated in the direction of arrow A.

で、個々のバネを小さく設計できより一層のコン
パクト化が図れる。 In this way, since the hard springs formed by the springs 21 and 22 can apply counterclockwise and clockwise torque, the spring constants K 1 and K 2 of the springs 21 and 22 can be selected to desired values. , it is possible to improve the detection ability in the low torque region, and at the same time, the width of the torque detection region can be independently set to a desired region width.Furthermore, since it is partially linear, it is easy to scale. Furthermore, since a single hard spring can provide counterclockwise torque and clockwise torque, there is an advantage that the number of parts such as a spring case can be reduced and the cost can be substantially reduced, considering the function. Furthermore, since the springs 21 and 22 having different natural lengths are arranged in parallel, the overall length of the spring case 14 can be significantly shortened. In addition, in the heavy load measurement region, the spring forces of the two springs 21 and 22 act, so each spring can be designed to be small and further compactness can be achieved.

設計できる利点もある。<Effects of the invention> As explained above, the present invention can be used for both clockwise and counterclockwise torque, and moreover, by arranging multiple springs with different coil natural lengths in parallel, the length of the springs can be gradually shortened as the amount of displacement increases. Since the spring force of the spring is applied, the detection ability in the low torque region can be improved, and at the same time, the torque detection region width can be independently set to a desired region width.
In addition, since one spring case can provide counterclockwise torque and clockwise torque, the number of parts such as the spring case can be reduced considering its functionality.Moreover, by arranging the springs in parallel, the overall length of the spring case can be shortened and compacted. Because it can be done, it can actually be made cheaper. Furthermore, since the spring force of two springs acts in heavy load measurement, there is an advantage that each spring can be designed to be small.
