This is the moment of force acting on a rotating shaft that transmits power, and is also called the torsional moment. If the transmitted power of this rotating shaft is P kW and the number of revolutions per minute is n , then the torque T (unit: newton meters N・m) acting on the shaft is given by T = 9.55 P / n (N・m). This torque is a quantity expressed as the product of force and distance, and is calculated by multiplying the force required to rotate the shaft by the distance from the shaft center. Therefore, to generate the same torque, the farther the distance from the center, the smaller the force required.

動力を伝達する回転軸に作用する力のモーメントで、ねじりモーメントともいう。この回転軸の伝達動力をPkWとし、毎分の回転数をnとすると、この時、軸に掛かるトルクT(単位はニュートンメートルN・m)はT=9.55P/n(N・m)で与えられる。このトルクは、力と距離の積で表される量で、軸を回転させるための力に軸心からの距離を掛けたものとなる。したがって、同じトルクを発生するためには、中心からの距離が遠いほど、小さな力で良いことになる。 [清水伸二] [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
