Spur Gears: Optimal Geometry, Methods for Generation and Tooth Contact Analysis (TCA) Program
Abstract
The contents of this report covers: (i) development of optimal geometry for crowned spur gears; (ii) methods for their generation; and (iii) tooth contact analysis (TCA) computer programs for the analysis of meshing and bearing contact of the crowned spur gears. The developed method for synthesis is used for the determination of the optimal geometry for crowned pinion surface and is directed to reduce the sensitivity of the gears to misalignment, localize the bearing contact, and guarantee the favorable shape and low level of the transmission errors. A new method for the generation of the crowned pinion surface has been proposed. This method is based on application of the tool with a surface of revolution that slightly deviates from a regular cone surface. The tool can be used as a grinding wheel or as a shaver. The crowned pinion surface can be also generated by a generating plane whose motion is provided by an automatic grinding machine controlled by a computer. The TCA program simulates the meshing and bearing contact of the misaligned gears. The transmission errors are also determined.
