How do you calculate the speed of the pulley?
The problem of the most simple calculation method is the diameter of the driving wheel on revolution, is equal to the diameter of the driven pulley on revolution, whether it's to slow down or speed up the belt and gear are calculated For example, the electric motor 1, 400, and the diameter of the belt wheel is 12 centimeters in diameter, which is equal to the 16800 passive wheel that must be matched with a 33.4 centimeter diameter pulley because only 33.4 times 500 is the 16800 The same is true for the gears, the diameter of the gears, whether it's the active wheel or the wheel is half a tooth
The ratio of the circumference of the outer diameter of the motor wheel to the machine speed and the ratio of the mechanical speed is calculated.
1400 goes to 500, you just have to slow down by 1, 400/500 = 2.8. If it's a belt machine, it only needs a belt wheel with a diameter of 2.8. Other people choose according to the actual situation. If it is a gear, the diameter of the circle is 2.8! But it's generally recommended that you use a pulley, which is easier
