How to calculate motor drive torque for ball screws
The motor torque required at constant speed is the sum of the torque needed to drive the load, the preload torque of the screw assembly, and the torque due to friction of the support bearings and seals. T c = torque at constant speed (Nm) T d = torque to drive the load (Nm) T p = torque due to preload (provided by manufacturer) (Nm)
Calculate Horsepower For Inclined Screw Conveyors
Calculate Horsepower For Inclined Screw Conveyors Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases. A U-trough conveyor, because ...
