APPLICATION OF FINITE-ELEMENT ANALYSIS FOR DETERMINATION OF LOAD SHARE, REAL CONTACT RATIO, PRECISION OF MOTION, AND STRESS-ANALYSIS

A loaded gear drive with point contact between tooth surfaces is consi dered. The principal curvatures and directions at a current point of t angency, the contact paths on tooth surfaces, and the transmission err ors caused by misalignment we consider as known. In this paper the fol lowing topics are covered: (1) Determination of the contact force and its distribution over the contact ellipse; (2) Determination of the to oth deflection, the load share, and the real contact ratio; and (3) St ress analysis by application of the finite element method. The discuss ed approach is illustrated with a numerical example.
