OPTIMAL-DESIGN OF INVOLUTE PROFILE HELICAL GEARS

A method is presented for minimising the centre distance of a helical gear set of prescribed power capacity using a fixed ratio of facewidth to pcd and formulae contained within AGMA procedures. Although power capacity is dependent upon many factors, the method has used module, n umbers of teeth, and helix angle as the significant variables. The pro cedure is based upon determining limiting values of AGMA geometry fact ors I and J which are derived in order to establish upper and lower bo undaries for the search interval of centre distance.
