First of all, it is necessary to calculate how much torque on the big wheel shaft to drive, and then according to the rotation speed required by the big wheel, the drive power can be determined. Power = torque (n/m) * speed (per minute) /9550, the number obtained is KW. Considering certain loss and allowance, the motor power is increased by 1.5-2 times according to how to reduce motor speed with pulleys the above calculated value.
After determining the motor power, the design of small pulley diameter. Small wheel diameter is not arbitrary, to consider the size of the motor shaft installation, as well as the belt transmission mechanism how to reduce motor speed with pulleys can transfer power. The wheel is too small and will slip.
After determining the diameter of the small wheel, design the how to reduce motor speed with pulleys transmission ratio through the relationship between the rotation speed of the big wheel and the motor speed to determine the diameter of the big wheel.
If the Angle is too small, it will slip. Therefore, it is necessary to confirm whether the Angle of the small wheel is enough. Otherwise, the tensioning wheel should be added, or the wheel diameter should be increased, or the rated speed of how to reduce motor speed with pulleys the motor should be reduced to reduce the belt transmission ratio.
This makes the machine to be able to depend on basically, otherwise is to put together.
In this design, the goal is to have the big wheel turn at the how to reduce motor speed with pulleys right speed and load, not just a random motor to drive it. If the motor has been set, then as stated in the question, changing the size ratio of the pulley can make the big wheel turn, but whether the speed can how to reduce motor speed with pulleys meet the requirements is not known.
The motor can change the output speed ratio by changing the pulley, how to reduce motor speed with pulleys reducing the diameter of the motor pulley can reduce the output speed ratio, and increasing the diameter of the motor pulley can increase the output speed ratio.
In a mechanical transmission structure, the ratio of the how to reduce motor speed with pulleys rotational speeds of two transmission components. Also called transmission ratio or speed ratio.
1.. Know the motor power, speed how to reduce motor speed with pulleys ratio and use coefficient, find the following formula of reducer torque: reducer torque =9550× motor power ÷ motor power input revolution × speed ratio × use coefficient
2. Know the torque and reducer output revolution and use coefficient, find the motor power required by reducer with how to reduce motor speed with pulleys the following formula: motor power = torque ÷9550× motor power input revolution ÷ speed ratio ÷ use coefficient
