第６図（ｂ）〜（ｄ）のベルト駆動方式は特にワークの
搬入搬出を自動化した試験機に適している。The belt drive system shown in FIGS. 6(b) to 6(d) is particularly suitable for a testing machine that automates the loading and unloading of workpieces.
Ｃ１発明が解決しようとする課題 しかしながら、この種のベルト駆動方式では。Problems that the C1 invention attempts to solve However, with this type of belt drive system.
使用頻度が多くなるにつれてベルト張力が弛む傾向にあ

動時の加速時間やモータ停止時の減速時間が長くなって
、試験効率が悪くなることがある。当初からベルト張力
を強めに調節すると、ワークの不釣合により振動する板
ばね（不図示）の拘束力が大きくなり、測定精度に悪影
響を及ぼすので、無闇にベルト張力を大きくできない。As the frequency of use increases, the belt tension tends to loosen, resulting in increased belt slippage, which lengthens the acceleration time when the motor starts and the deceleration time when the motor stops, resulting in poor test efficiency. If the belt tension is adjusted to be strong from the beginning, the restraining force of the leaf spring (not shown) that vibrates due to the unbalance of the work will increase, which will have a negative effect on measurement accuracy, so the belt tension cannot be increased arbitrarily.

度が悪くなる。In addition, in a testing machine that directs the measured unbalanced angular position in a predetermined direction after the test is completed, the rotation angle of the boob is detected by a rotary encoder, and the motor is driven according to the result to adjust the angle of the workpiece. Since the position is determined, if the belt tension is loose and slip occurs, the accuracy of angle detection by the rotary encoder and subsequent positioning operation will decrease. In particular, if there is an idler pulley between the work and the workpiece, the belt does not stretch evenly, resulting in poor accuracy.
本発明の技術的課題は、不釣合測定精度に影響を与える
ことなくモータ加速時間を短縮することにある。The technical problem of the present invention is to shorten the motor acceleration time without affecting the unbalance measurement accuracy.
００課題を解決するための手段
