| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 95 === Gear shaving is the most important refinement method to manufacture the helical and spur gears by the CNC shaving machine. In this thesis, the rack cutter is used to generate a shaving cutter firstly, the shaving cutter is then used for the generation of gears.
The rack cutter with modified profile proposed by Professor Litvin is used to derive the mathematical model of shaving cutter. The shaving process is then simulated according to the shaving machine to generate the gear tooth surface with double crowning. The TCA of two types of tooth surfaces, i.e., double crowning and crowning in longitudinal direction only, are investigated in this research.
Taguchi method is used to find out the optimum combination of parameters in different conditions of assembly. The results of this thesis provide important informations for the study on the shaving machine and characteristics of gears. It also provides the reference for the stress analysis of shaved gears.
