There's an assumption manufactured during the pressure her comment is here velocity calculation that the load P is solely a thrust load about the lead screw nut. This involves good load advice by a load bearing member such as a guidebook rod or ball bearing linear guideline rail. It is bad design and style follow to implement a lead screw as both of those the driving component and cargo steerage member. The end result is off axis loading of your nut which makes a moment load condition as shown below in Determine 2a. Implementing a minute load for the lead nut could cause many likely failure strategies such as mounting, PV, and excessive drag. If The instant load is massive sufficient a mounting failure in the form of fracture is usually a result of substantial tension concentrations at the changeover involving the mounting attribute (thread or flange) and also the nut body.
