Reducer torque = 9550 × Motor power / motor revolutions × Speed ratio of reducer × The symbol of efficiency torque is N.M;
9550 is a fixed number. The power of the motor is several kilowatts (kw) of the motor matched with the reducer. Divided by the number of revolutions of the motor, the minimum number of revolutions of the domestic motor is 1390, and the maximum is 1490. When we calculate it, we calculate it by 1400 revolutions, and the difference is not much. If you want to be accurate, you can refer to the motor sample, for example, 1390 revolutions for 0.37kw, 1420 revolutions for 3KW, 1460 revolutions for 11kw, The unit is R / min; The speed ratio of the reducer is not easy to explain. The efficiency can be calculated in this way. The hard tooth surface gear reducer is calculated as 0.9 for the poor and 0.95 for the good, but the imported one is generally calculated as 0.95. The reducer with worm gear is calculated as 0.65 for the poor and 0.7 for the good.
The above formula describes how to calculate the output torque of the reducer, but when selecting the motor, it is necessary to select the motor power matching the torque force of the reducer. Different speed ratios should select different power motors. If the power is too large, the service life of the reducer will be reduced.
