When designing a screw conveyor, there are several important elements to consider: Capacity. To determine the appropriate screw diameter, calculate the volume per hour that the screw conveyor will need to transport. Design and drive. Given the range of different screw designs, the design must consider the ultimate goal of the conveyor.

If you plan on driving your conveyor pulley directly by your motor shaft you do not need to consider it. The conveyor belt will always have some belt efficiency so this must be considered and it can be easily looked up. The …
Drive torque is primarily influenced by the axial load on the screw and the screw's lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force (drilling, punching, etc.), but also includes the force required to move the load. Since most ball screw assemblies use profiled guide ...

According to one manufacturer's product-number system, size 726 defines a gearbox that has a 2.62 center distance. Such charts also work in reverse, to let engineers confirm the torque or speed of a given gearbox size. This chart provides values for C-face motor input (flanged) or directly coupled (non-flanged) motors.
force on the screws and creates frictional resistance. As a result, additional torque is required to start and operate a screw feeder when compared to a screw conveyor. Special consideration is required when designing screw feeders. The starting torque requirements of screw feeders can be as much as 2-1/2 times the demand running torque.

Drive torque is primarily influenced by the axial load on the screw and the screw's lead. F a = total axial force (N) P = lead (mm) η = efficiency of ball screw. The axial load is not only the process force …
The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.
The vector formula that yields the torque vector τ is: τ = r × F The vector r is the position vector with respect to an origin on the axis of rotation (This axis is the τ on the graphic). This is a vector with a magnitude of the distance from where the force is applied to the axis of rotation.
Step 1: Determine speed and torque, contd… A. Speed Equation 1: N = (9.55 • V Load ) / r Where 9.55 has the units sec-rev/min. From the given system requirements, we know V Load = 12 in/sec and r = 2 in, therefore N = 57.3RPM. B. TACCEL T ACCEL may be ignored unless acceleration time is critical.
