COMPUTER AIDED SIMULATION OF THE ANALYSIS AND SYNTHESIS OF SPIRAL BEVEL GEARS

This thesis is a study in the area of analysis and synthesis of spiral bevel gears. The contents of the thesis covers the solution to the following problems: (1) Modelling of the gearing based on gear generation by two rigidly connected tool surfaces which are in contact along a line. The method of generation utilizes either two cone surfaces or a combination of a cone surface and a surface of revolution. (2) Derivation of gear tooth surfaces as the envelopes of generating surfaces. (3) Computer-aided simulation of conditions of meshing and bearing contact. (4) Synthesis of spiral bevel gears with improved bearing contact and zero kinematical errors.; The thesis is complemented with computer programs which provide effective machine-tool settings, data about the kinematical errors of gears, and the bearing contact. The important results of the thesis have been presented in a number of publications.
