DEVELOPMENT OF A NEW TYPE CUTTER ″REVOLVING TYPE PINION CUTTER″ FOR THE HOBBING OF THE FACE GEAR.

A new type of cutter ″revolving type pinion cutter″ for the hobbing of the face gear has been developed in consideration of facility of manufacturing. The form of the cutter was analyzed and the calculations were done to show the effect of various form factors on the cutter accuracy. The result shows that the cutter can be used for the hobbing of the face gear. A cutter was made practically giving all the details of various steps necessary to make it. Face gear was hobbed by fixing it in the hobbing machine. The form of the cutter was confirmed by taking the tooth bearing of the generated face gear in actual mesh. It is proposed that the revolving type pinion cutter be used for the hobbing of the face gear for better productivity and economy.
