| Summary: | The coast side teeth of asymmetric gear with a small number of teeth which using small pressure angle lead to undercutting.Traditional undercutting caused by rectilinear segment of the rack-cutter,called the first type of undercutting.Besides,another undercutting caused by the rack-cutter fillet,called the second type and the third type of undercutting.In order to study the boundary condition,rotational coordinate system attached to generated gear and translational coordinate system attached to rack cutter are established.The parametric equations of boundary fillets for the second and third undercutting are solved,and the maximum fillet radius coefficient of the rack-cutter is obtained.The results show that,in order to avoid the undercutting of the tooth,it is necessary to satisfy the boundary condition of the first type and the second type of undercutting simultaneously. |
