Thoroughly sizing the lead screw assembly is essential towards the success of the applying. Defining the whole thrust and maximum linear velocity necessary is a good start line. There are numerous things to take into consideration when calculating the maximum thrust expected like acceleration, load, axis orientation, drag forces, and many others. The most speed is often based on the amount time is obtainable to finish the travel which includes acceleration and deceleration ramps if desired. A factor of security can be included to both the utmost thrust and pace. In several cases the maximum thrust will slim the selection of lead screw diameters readily available as an answer. The critical screw speed (mentioned later on) may additionally Restrict the diameters out there.
