齿轮加工装置
摘要：
本发明提供一种齿轮加工装置，能够通过使加工用工具以及工件高速同步旋转进行切削加工来加工高精度的齿轮。加工用工具(42T)具备：粗加工用工具刃(422S)，其粗加工齿轮(G)的齿(g)的齿根(ge)以及两侧面(sr、sl)；右侧面精加工用工具刃(422R)，其精加工齿(g)的右侧面(sr)；以及左侧面精加工用工具刃(422L)，其精加工齿(g)的左侧面(sl)。由此，各工具刃(422S、422R、422L)分别切削齿轮(G)的齿(g)的一部分且不同的部位，因此能够降低切削阻力，抑制切削加工时的自激振动的产生，而能够提高齿轮的齿向精度。
摘要（英）：

A gear machining device is provided which can machine an accurate gear by a cutting process by synchronously rotating a machining tool and a workpiece at a high speed. A machining tool (42T) includes roughing cutting teeth (422S) for roughing bottom lands (ge) and right and left side faces (sr, sl) of teeth (g) of a gear (G), right side face finishing cutting teeth (422R) for finishing the right side faces (sr) of the teeth (g), and left side face finishing cutting teeth (422L) for finishing the left side faces (sl) of the teeth (g). The cutting teeth (422S, 422R, 422L) thus cut different parts of the teeth (g) of the gear (G). This can reduce cutting resistance and suppress self-vibration during the cutting process, thereby improving tooth trace accuracy of the gear.
