Screw selection calculation
Webb5 maj 2024 · Selection Capacity (SC) is the capacity adjusted for special pitch, applied in the selection of the screw conveyor diameter. Calculation of special screw conveyor capacities is as follows: Nomenclature: SC = Selection Capacity. CFH = required Capacity in Cubic feet per Hour (ft 3 /hr) CF = Capacity Factor. Capacity factors for Special Pitches. Webb(for solid screw shaft, use `WK^2` = 1/8`WD^2` where W = weight of screw (lbs.) D = diameter of screw (ft.)) `DeltaRPM` = Change in rotational speed (rpm) t = Time period to accelerate (sec.) † Formulas for acceleration torque and acceleration force are average values only for the time period values used.

WebbWhen a lead screw has more than one start, it is referred to as a multi-start lead screw. The number of starts begins to vary with modified acme and high lead angle threads (>20 degrees). For instance, you can get a ½" diameter x .500" lead, with both 4 starts (.125" pitch, 8 TPI) and 5 starts (.100" pitch, 10 TPI). WebbIt is quite easy to calculate steps per mm as long as the designer knows the stepper motor's type of drive. For leadscrew driven systems, the “stepper motor’s steps per mm is expressed as: Or Where: N=number of turns that the leadscrew must travel to move 1 mm p=leadscrew pitch
WebbSelection Procedure The first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation: WebbBall / Lead Screw Specifications; Diameter. D B = in mm. Total length. L B = in mm. Lead (pitch) P B = in/rev mm/rev (Distance the screw moves in one rotation) Efficiency. η = % ref; ballscrew 80 〜 95%,
