Cast Stainless Steel Pulley

Cast Stainless Steel Pulley
First of all, to calculate how much torque on the big axle can be driven to get, and then according to the needs of the big wheel speed, in order to determine the drive power. Power = torque (Nm) * speed (rpm) / 9550, the number is KW number. Considering a certain loss and margin, the motor power calculated by the above expansion of 1.5-2 times.

Intriduction of Cast Stainless Steel Pulley:

First of all, to calculate how much torque on the big axle can be driven to get, and then according to the needs of the big wheel speed, in order to determine the drive power. Power = torque (Nm) * speed (rpm) / 9550, the number is KW number. Considering a certain loss and margin, the motor power calculated by the above expansion of 1.5-2 times.

Determine the motor power, only to design a small pulley diameter. The diameter of the small wheel is not arbitrary, to consider the size of the motor shaft installation, as well as the belt drive can transfer power. Wheels are too small to slip.

After determining the diameter of the small wheel, and then through the relationship between the wheel speed and motor speed design transmission ratio, to determine the diameter of the big wheel.

The wrap angle is too small will slippery, so in the end to confirm whether the angle of the small round is sufficient, or need to add tension wheel, or increase the wheel diameter, or reduce the rated motor speed, reducing the transmission ratio of the belt drive.

This machine is basically reliable, otherwise it is patchwork.

In this design, the big wheel can rotate at the right speed and load, which is the goal, rather than just take a motor to drive. If the motor has been set, then as mentioned in the title, change the size of the pulley size can make a big turn, but the speed can meet the requirements do not know.
