Speed ratio=motor output speed ÷ reducer output speed (also known as' transmission ratio ')
1. Knowing the motor power, speed ratio, and usage coefficient, calculate the torque of the reducer using the following formula:
Gearbox torque=9550 x motor power ÷ motor power input speed x speed ratio x service factor
2. Knowing the torque, output speed of the gearbox, and usage coefficient, calculate the required motor power for the gearbox using the following formula:
Motor power=torque ÷ 9550 × motor power input speed ÷ speed ratio ÷ service factor
Calculation of motor torque
The "torque" of the motor, measured in N? M (Newton meters)
The calculation formula is T=9549 * P/n.
P is the rated (output) power of the motor, measured in kilowatts (KW)
The denominator is the rated speed n, and the unit is revolutions per minute (r/min)
P and n can be directly found on the motor nameplate.
Assuming the rated power of the motor is P (kw), the speed is n1 (r/min), the total transmission ratio of the reducer is i, and the transmission efficiency is u.
Then: Output torque=9550 * P * u * i/n1 (N.m)
N=60f/p, p is a polar logarithm
Calculate the synchronous speed based on the motor's synchronous speed n=60f/p:
At 50HZ: 2-pole motor at 3000 revolutions per minute; 4-pole motor at 1500 revolutions per minute; 6-pole motor at 1000 revolutions per minute
At 60Hz: 2-pole motor at 3600 revolutions per minute; 4-pole motor at 1800 revolutions per minute; 6-pole motor 1200 rpm
The frequency difference is only 10Hz, with a small number of poles and a large difference in speed. I don't know how many poles your motor has. Besides that, because the above calculation is synchronous speed, the covered pole motor is also an asynchronous motor. Therefore, try to adjust the slip rate of the motor in the motor design to control the speed

Key points for selecting planetary gearboxes

　　1The selection of precision planetary gear reducers should match the installation flange when clicked. Because motors are classified according to the installation flange, and precision planetary gear reducers are also determined by the installation flange to determine the model.

　　2Determine the reduction ratio. Precision planetary gear reducer manufacturers will determine the reduction ratio according to their own equipment requirements. Currently, it is generally divided into three stages, and there are also two stages. Three stage reduction can achieve100Above, the second level deceleration is20-100Between them, the first level of deceleration is20The larger the level, the larger the gap, and the more expensive the price. When determining the reduction ratio, it is advisable to choose one that is similar to the desired reduction ratio, following this formula: servo planetary reducer reduction ratio=Servo motor speed/Servo planetary reducer output shaft speed.

　　3Determine the appearance of the gearbox. Precision planetary gear reducers come in both circular and square shapes, but generally speaking, the manufacturing process of square reducers is more complex than that of circular reducers, and the rated output torque is also larger than that of circular reducers, so they are also more expensive in price.

　　4Determine the input and output forms of the gearbox. The input forms of the reducer include hole input and shaft input. The output of the reducer includes hole output, shaft output, flange output, etc.

　　5Pay attention to torque calculation. Torque calculation can play a significant role in the lifespan of precision planetary gear reducers, so it is important to note that the torque value of acceleration should not exceed the load torque of the reducer.

The selection of planetary gearboxes should follow the principle of combining applicability and economy, which means that the various technical indicators of planetary gearboxes can meet the requirements of the equipment and save costs.'Over''Compared to 'not enough''All of them will lead to cost waste, so it is very important to choose planetary gearboxes correctly.

Planetary gearbox is a widely used industrial product, with performance comparable to other grades of gearbox products, but at the same price as industrial grade products, and is widely used in industrial applications.
