FULL COMPLEMENT CALCULATOR AND NEEDLE BEARING MOCKUP TOOL

grabcad

This SolidWorks model calculates and models a "full complement" — or the maximum number of needle bearings which can be placed around a given shaft diameter. In other words, it prototypes bearing implementations which have to be built from available needle components, wherever we find that commercial varieties of more complete bearings will not meet our requirements.Integral calculations report needle-to-needle clearance for this greatest possible needle density — with the principal advantages of a full complement being, a) that it supports the greatest possible loads for the needle diameter; b) that no cage is required (which generally equates at least to minimal initial expense); c) that needles can be extended fully to the structures which support the shaft (putting the shaft moreso into shear than flexure); and, d) that it also better supports the possibly minimal walls of outer ring spatial limitations. Full complements however, generally cannot be operated at the higher potential rotation speed limits which caged designs are generally capable of.So, the exercises of this model are regularly performed wherever existing commercial needle bearing designs may not fulfill our needs; and thus, this model solves the problems expressed the other day in my previous upload, https://grabcad.com/library/using-parameterization-to-prototype-and-evaluate-prospective-bearing-designs-solidworks-and-step-models-1 ... by enabling us to bracket targeted parameters, to weigh the consequences, and in turn to determine an ideal design.The trigonometric calculations faithfully calculate the true sector of an arc subtended by the needle diameter as juxtaposed to the axis diameter. Thus, every feature and projection of the resultant model is exactingly calculated from shaft or axis diameter, needle diameter, optional needle length, and optional outer ring wall thickness inputs within the model's integral equations page. The optional inputs complete its capacity to model your exact prototype.If anyone has solid advice on exporting these SolidWorks + parameters formats so that the calculation capabilities are preserved in the conversions, I'll be glad either to make or to provide for the conversions and uploads.(C) Copyright 20240314 by mike montagne.
