How to calculate the torque of the reducer?

The torque of the reducer is the output torque of the motor, which is one of the basic parameters of the motor.The torque of the reducer is inseparable from the motor speed, power and other factors.Today Jiangsu Juzhili will take you to understand the commonly used torque formula and the calculation of servo motor torque.Hope the knowledge we share can help you.

1. Formula: T=9550P/n The formula commonly used in engineering: torque; power; calculation formula for the relationship between speed.

Among them: t-torque; 9550-constant (no need to investigate its source); p-motor power (kw); n-output speed (rev/min)

Note: It should be noted that the factor of gear transmission efficiency loss should be considered when calculating the torque through the reducer.

4. The torque calculation formula of the servo motor is: T=F*R*reduction ratio.Example: driving a 100kg object, R=50mm, reduction ratio: 1: 50,

3. Regarding the reduction ratio:

1) The concept of reduction ratio: the transmission ratio of the reduction device, which is a transmission ratio, refers to the instantaneous input speed and output speed in the reduction mechanism

The ratio of degrees is represented by the symbol 'I'.If the input speed is 1500r/min, the output speed is 25r/min, the reduction ratio is: i=60:1.The reduction ratio of the general reduction mechanism is marked with the actual reduction ratio, but some special reducers, such as cycloid reducers or harmonic reducers, sometimes use the rounding method without denominator for rounding.For example, the actual reduction ratio may be 28.13, but it is generally marked as 28.

2) Calculation method of reduction ratio

a. Define the calculation method: reduction ratio = input speed and output speed.

b General calculation method: reduction ratio = working torque 9550 motor power motor power input revolutions work coefficient.

C. The calculation method of the gear train: reduction ratio = number of driven gears and number of driving gears (in the case of multi-stage gear reduction, the number of driven gears and the number of driving gears of all meshing gear sets can be multiplied.

d. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel and diameter of driving wheel.
