| Abstract: | Kinds of the side cut die for net forgings of bevel gears made by EDM are pointed out.Using the equation of the theoretical curve of the flank profile of side cut die,the authors fit the curve of flank profiles of side cut die by arc and derive the calculating equation of precision analyzing method.Using the fitting curve of the flank profile of the side cut die for net forgings of BJ130 bevel gears,the authors also prove that this mothod possesses a very high fitting precision.The authors provide the fitting mothod used in manufacting the side cut die for the other bevel gear forged.Using CAD/CAM technique,the authors also propose the method of accomplishing the side cut die for the bevel gear by wire cutting. |
