An axis of movement is necessary to elevate a 15 lbs object twelve inches in just three.five sec. Determined by the motion profile and consideration for drag as well as a little margin of safety a utmost linear velocity of 4 in/sec having a thrust load of 25 lbs is described for that lead screw. A “Easy/Easy” (Desk one) screw assist geometry is proposed for the design, and due to the duration with the lead nut, stroke size requirement, plus some margin at possibly close of stroke the gap in between supports is sixteen inches. Resulting from acceptable minimal positional precision prerequisite, and gravity around the vertical axis that could bias the nut to one facet on the thread a standard, or normal goal lead nut is chosen (instead of an anti-backlash nut). Dependant on a table for loading and recommended screw diameters mentioned about the manufacturer’s Web page a 0.
The rotating movement made by the electric motor is handed on for the spindle, producing the chuck and workpiece to rotate alongside it.
Thoroughly sizing the lead screw assembly is essential towards the achievements of the applying. Defining the entire thrust and highest linear speed required is a great starting point. There are various factors to take into consideration when calculating the utmost thrust needed for instance acceleration, load, axis orientation, drag forces, and so forth. The most speed is often determined by the amount of time is available to finish the vacation which incorporates acceleration and deceleration ramps if necessary. An element of basic safety can be added to the two the utmost thrust and pace. In several cases the most thrust will narrow the selection of lead screw diameters offered as an answer. The significant screw pace (reviewed afterwards) may also limit the diameters obtainable. Deciding over at this website on a lead calls for more information and facts which incorporates resolution prerequisites, backdriving considerations, and drive enter availability.

Another essential piece of knowledge in the design of this axis would be that the lead is effective adequate to backdrive, and to help keep the load from slipping beneath its individual body weight when ability is my explanation faraway from the motor, a brake will should be executed.
