COMPUTER AIDED DESIGN AND ANALYSIS OF GEAR TOOTH GEOMETRY (CAD/CAM, MANUFACTURING, DIFFERENTIAL)

A simulation method for gear hobbing, shaping, straight and spiral bevel gear manufacturing is presented. The enveloping theory for gear tooth profile generation process is the basis of this method. The application of the procedure is with the computer aided design of standard and nonstandard tooth forms. The inverse procedure of the enveloping conjugate gear tooth profile is presented for the cutter geometry. The kinematic relations for the tooth surfaces of straight and spiral bevel gear are proposed. The tooth surface equations for these gears are formulated in a manner suitable for their automated, numerical development and solution.; Spur gear stress analysis results are presented for a variety of loading conditions, boundary conditions, fillet radii, and rim thickness by using finite element method. A finite element computer program UCIN-GEAR was developed for determining stresses and deflections in standard involute spur gears.
