An axis of motion is required to raise a 15 lbs object twelve inches in just three.5 sec. Depending on the motion profile and consideration for drag in addition to a little margin of security a optimum Read More Here linear speed of four in/sec that has a thrust load of 25 lbs is described for that lead screw. A “Basic/Straightforward” (Table 1) screw help geometry is proposed for the design, and due to the duration on the lead nut, stroke size prerequisite, and several margin at both stop of stroke the space concerning supports is 16 inches. Resulting from sensible reduced positional precision prerequisite, and gravity around the vertical axis that may bias the nut to one facet in the thread a standard, or normal purpose lead nut is chosen (instead of an anti-backlash nut). Dependant on a table for loading and proposed screw diameters mentioned about the company’s Internet site a 0.
