There is an assumption produced in the tension velocity calculation the load P is purely a thrust load within the lead screw nut. This calls for right load direction by a load bearing member like a tutorial rod or ball bearing linear guideline rail. It's weak layout apply to use a lead screw as both equally the driving element and cargo assistance member. The end result is off axis loading on the nut which creates a minute load condition as shown underneath in Figure 2a. Making use of a moment load to your lead nut can cause a number of potential failure approaches which includes mounting, PV, and too much drag. If the moment load is substantial enough a mounting failure in the shape of fracture can be due to high anxiety concentrations for the transition among the mounting element (thread or flange) and also the nut human body.
