Abstract

The authors propose modification of geometry of spur gears that enable to localize the bearing contact and reduce the level of transmission errors. Methods for generation of spur gears with the modified geometry are proposed as well. Computer programs for simulation of meshing and contact of misaligned spur gears with the modified geometry have been developed. The developed theory is illustrated with numerical examples.
