Effects of Cone-Shaped Error of Big Plane Wheel’s Grinding Face on Gear Helix Deviations[J]. Optics and precision engineering, 2010, 18(3): 630-637.DOI:
The total helix deviation is one of mandatory inspection items in gear evaluation. Out of development of ultra precision master gear
taking Y7125 grinder as an example
effects of the cone–shaped error of grinding face on the helix deviations was derived. The results show that the minimum effective bearing width has little effect on gear helix form deviation; however
as the increase in gear width
the effect of the cone –shaped error on gear helix form deviation will significantly increase and the cone–shaped error can make curve of gear helix deviation be in arc-shaped and the crowns of arc vary from dedendum to addendum. Finally
the above conclusions are verified by gear grinding experiment and precision measurement.
