The formula for calculating the pulley
The diameter of the belt wheel is 28cm, which must mean the pulley of the mill, so the whole drive belongs to the deceleration drive, and the motor pulley must be smaller than 28cm. The calculation should be as follows: 1400:900 = 28: x x is the diameter of the pulley wheel It is important to note: 4 of the asynchronous motor, with the greater the power, the slip is, the greater the generally, under 10 kw 4 pole motor, the slip is not too big, the motor output speed can reach 1450 RPM.
Wheel diameter X3.14 X motor speed X motor pulley diameter/turbine wheel diameter/deceleration speed ratio = saw blade speed; Wheel diameter X3.14 X motor speed X motor pulley diameter/saw blade speed/deceleration speed ratio = turbo pulley diameter; Line speed/wheel diameter X3.14 X motor speed/worm pulley diameter/decelerator speed ratio = motor pulley diameter.
The speed of the pulley is calculated, for example, the speed of the motor is 1440, and it wants to be reduced to 220. The method is as follows: 1440 * small pulley diameter = 220 * large pulley diameter. You can solve this equation. For example, the main belt plate is 300mm in diameter and the speed of the pulley is 2000 RPM
Disc diameter, conversion method: 300 times 2,000 divided by 800 is the diameter. So strictly speaking, it's going to be equal to the circumference, which is just multiplying by 3.14, divided by 3.14, and this is just simplifying it, and the result is the right thing to do. The diameter of the pulley is 10310 mm, and the diameter of the belt wheel should be: 310 * 900/1460 = 191 mm. How do you calculate the diameter of the pulley Formula is as follows: A/b * a = b Active wheel speed is: A The active wheel diameter is: a The passive wheel speed is B The diameter of the passive wheel is b
