Gear processing equipment

Japanese Patent JP6340764

B2

There is provided a gear machining apparatus (1) that causes a machining tool (42B) and a workpiece (W) to rotate at a high speed in synchronization with each other to machine a highly accurate gear (G) through cutting. The machining tool (42B) is manufactured such that each of pitches (Pb) between tool blades (421B) of the machining tool (42B) is an integer multiple of a pitch (P) between teeth (g) of the gear (G), the integer multiple being equal to or larger than double. By using the machining tool (42B) for cutting performed by the gear machining apparatus (1), the number of the tool blades (421B) of the machining tool (42B), which are brought into contact with the workpiece (W) at the same time, is reduced. Thus, it is possible to suppress occurrence of self-excited vibrations during cutting by reducing the cutting resistance. Thus, it is possible to enhance the tooth trace accuracy of the gear (G) (reduce the deviation of the actual tooth trace of the gear (G) from the ideal tooth trace).
