This invention relates to machines for generating and cutting gears of the spur type, by the action of a planing cutter which is, itself, shaped like a spur gear; and is more particularly concerned with machines of this class which are designed and adapted to operate at high speeds. In my prior Patents No. 1,478,472, dated December 25, 1923, and No. 1,463,806, dated August 7, 1923, I have disclosed gear generating or shaping machines which are capable of operating efficiently and with the desired accuracy at speeds several times greater than previously employed. In producing the invention, which I am now about to describe, my principal object has been to increase still further the speed of operation of such machines. I have accomplished this object and attained a speed of operation from seventy-five to one hundred percent greater than that which I have accomplished by the machines disclosed in the above identified patents at the same time without causing objectionable vibration as a consequence of such increased speed, by making the reciprocating parts lighter and introducing other improvements, by which the use of such lighter parts is made possible with the preservation of the high quality of accuracy which has been a characteristic of the machines produced according to my inventions, and has become an essential in the gearing art.
