ad-dendum circle of the drivermay be obtained whenthe arc of recess is given.Sufficient clearance mustbe allowed between theaddendum circle of onewheel and the root circleof the other. To express the relationship analytically, let a be the arc ofapproach, r\ and 7*2 the radii of the two pitch… … The following approximate construction may be used to measure off, along acircle, an arc of given length: At the point A (Fig. 339) draw a tangent, AB,equal to the given length, and in AB take AC such that AC = iAB. With 0as centre, draw the circular arc BD to meet the given circle in D : then AD…
