【発明が解決しようとする課題】ところで前述のような
従来の歯形成形装置では、図１２，１３に示すラック形
工具方式の場合は歯形成形に必要なラックの長さは素材
１が６〜８回転する分が必須となる。By the way, in the above-described conventional tooth forming apparatus, in the case of the rack type tool system shown in FIGS. 12 and 13, the rack length required for the tooth forming is 6 to 8 for the material 1. The amount of rotation is essential.
【００１０】つまり素材外周の６〜８回長さとなり、例
えば素材１の直径が５０ｍｍの時９４２〜１２５６ｍｍ
となり、装置構成としては上下ラックでその倍の長さと
なる事から、素材径の大きな歯車の加工では装置が大き
くなりすぎ極めて不都合となる不具合がある。That is, the length of the outer circumference of the material is 6 to 8 times, for example, 942 to 1256 mm when the diameter of the material 1 is 50 mm.
Therefore, since the upper and lower racks have a length twice that of the apparatus configuration, there is a problem that the apparatus becomes too large and extremely inconvenient when machining a gear having a large material diameter.
【００１１】また図１４に示す円形転造工具の場合は、
装置構成は比較的簡単であるが、同一歯形を用いた転造
工具２０，２１のみで加工するため、歯の割り出しがむ
ずかしかったり、仕上精度が、あまり良くない不具合が
ある。In the case of the circular rolling tool shown in FIG. 14,
Although the device configuration is relatively simple, there are problems that the teeth are difficult to index and the finishing accuracy is not very good because the rolling tools 20 and 21 using the same tooth profile are used for processing.
【００１２】また工具２０，２１が磨耗しやすい欠点が
あり、さらに同一工具での加工のため成形に要する時間
が長くなりやすい不具合があった。Further, the tools 20 and 21 have a drawback that they are easily worn, and further, there is a problem that the time required for molding tends to be long because of machining with the same tool.
【００１３】また図１２，１３，１４に示す従来例に共

だ分だけ、素材の材料は盛り上がるが、端面近くの部分
では、材料は軸方向に逃げやすいので図１０に示すよう
に端面にはみ出てバリ９となりやすい不具合がある。Further, as a drawback common to the conventional examples shown in FIGS. 12, 13 and 14, since both end surfaces in the axial direction of the material at the time of processing are free, when the tool is pushed into the material, only the amount of the tooth of the tool biting in, Although the material of the raw material rises, the material near the end face easily escapes in the axial direction, so that there is a problem that it easily sticks out to the end face to form a burr 9 as shown in FIG.
【００１４】そのため図１１に示すように軸方向にはみ
出る量だけ端面に勾配８をつけた素材形状としておく前
処理加工が必要となる。Therefore, as shown in FIG. 11, it is necessary to carry out a pretreatment for forming a material shape in which the end face has a slope 8 by an amount protruding in the axial direction.
