The root stresses and tooth deflections of welded structure gears (thin rim) are computed by the 3-dimensional finite element method (FEM). The effects of shapes of tooth, the partitions and constraint conditions of gear models on the root stresses and tooth deflections of a thin-rimmed gear with ribs and a web are discussed. A suitable gear model and constraint condition for the analyses of the root stresses and tooth deflections of welded gears by FEM are indicated. The root stresses and tooth deflections computed by FEM for the rack-shaped tooth model adopted in this report agree well with those measured. The root stresses and tooth deflections of a symmetric type of single web gear are clarified to a considerable extent.
