Research on Deviation Analysis and Proportional Correction Method for Face Gear Tooth Turning
Based on the mathematical model of gear turning cutters and face gears
a tooth surface deviation model for gear turning is established using gear shaping as the theoretical tooth surface. Using the incremental method
the influence of machining parameters such as offset distance
cutting depth
shaft intersection angle
and rolling ratio on tooth surface accuracy is analyzed
and a method for correcting the tooth surface deviation ratio of face gears is presented. The tooth surface deviation in gear turning is mainly concentrated at four vertex positions
and the tooth surface deviation is most sensitive to the correction of the roll ratio
but not to the offset amount. Using a three-parameter deviation sensitivity matrix
the proportional relation between the tooth surface deviation and machining parameters is determined. Through two trial cuts
the tooth surface deviation is corrected
and the feasibility of the proportional correction method is verified.
