May 18, 2016· Does the ball screw pitch diameter get canceled out in the calculations I would have thought that as the diameter increased the torque would be reduced Bharadwaj says September 25, 2018 at 1:37 am What if the movement is horizontal, ie, the load on ball screw is not axial but radial How would the calculations change? , Design from .

A screw in the horizontal is a conveyor or feeder, but as a screw is inclined it very quickly becomes a lift or pump All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws

Most CEMA-approved screw conveyor manufacturers have the capacity calculation and the CEMA guidelines as part of their screw conveyor design software Inclined Screw Conveyors Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal ,

The ball screw runs the entire length of the x axis and is supported on either ends by bearing supports For simplicity sake we will define the nut mounting as flange, material as alloy steel, thread direction as right hand and product series as Metric The system orientation in this application is horizontal with a screw driven design
