How did the motor select the pulley?
Both of the increase, with good small pulley, first to calculate large pulley, calculation formula, with the speed of the machinery needs divided by first rated speed of the motor and then multiply to lack the scheduled first pulley diameter can be
When you replace the new pulley, the pulley will no longer suitable for inner diameter, if you just replaced the reducer and motor, the other side is the transmission items without change, generally don't have to increase the belt width. If reducer ratio increases more, suggest adding a belt, such as using the original belt type 2 B, can now be increased to 3, just adjust on the pulley accordingly.
The method of selecting the belt wheel for the motor is: Determine the speed of the drag machine according to the production process requirement. After determining the speed of the drag mechanism, the following formula can be calculated: The speed of motor speed/drag mechanism is the diameter of the pulley diameter/motor pulley. It is derived from the formula: the diameter of the motor pulley is the diameter of the mechanical pulley and the motor speed of the pulley.
