The Impact of Meshing Transmission of Arc Gear by Hobbing Method and Central Distance Error
The tooth profile of arc gear is no longer arc after hob process, it’s a section of curve which is similar to the arc. Although there have been confirmed that this curve which is similar to the arc can make sure that the transmission ratio and meshing point of two gears will not change ,pressure angle at the meshing point will certainly change, and there is also no literature report how much this curve has impact on pressure angle. The impact of meshing transmission of arc gear by central distance error researched by current literature is based on arc tooth profile, this study is not suitable for the tooth profile processed by hob, and there is no literature report how much central distance error has impact on transmission ratio, pressure angle and mesh point of arc gear which processed by hob. In this article, the author has work out this problem by use tooth surface equation.
