  • For the purpose of expanding the application range of face gear,a new design of offset orthogonal arc tooth face gear was proposed by combining the characteristics of both face gear and arc tooth.The equations of full tooth surfaces were derived,and the visualization of tooth surfaces was realized in Matlab.Based on the mathematical model and the undercutting theory,the undercutting location of the gear was calculated.Result was confirmed by the simulation experiment using CATIA secondary development.Several factors influencing with the minimum inner radius were studied.The research showed that:while the positional parameter had a small negative influence on the minimum inner radius,the radius of the gear cutter and the offset distance both had positive influence on it.When the module of gear increased,the inner radius increased greatly.In the end,the location of the tooth tipping point was confirmed and the tooth width of face gear was calculated.
