来の歯切り盤などでは切削が困難となる場合があった。Conventionally, large module gears, which are often used in construction equipment poles, etc., have been cut from materials using hobbing machines and gear shapers, just like small module gears. For this reason, it takes a lot of time to manufacture the module, resulting in poor work efficiency, and as the module becomes larger, cutting resistance also increases, making it difficult to cut using conventional gear cutting machines.

This allows for efficient processing in a short period of time.

で切削する。When cutting the gears of the large module gear 6, the indexing board 5 is first set according to the module and the number of teeth, and after the setting is completed, the large module gear 6f is fixed on the indexing board 5. Next, operate each hand) "le B, q,
Move each slide base lo, 1le equidistantly from the center line o - o' of the large module gear 6 in the Y-axis direction, and set each saw blade 20, 2+ to 2t as shown in FIG.
In this state, each saw blade 20.2 is cut by the drive motor 6.17.
While rotating the feed motor 3, the slide base 4 and the large module gear 6 attached thereto via the indexing board 5 are moved along the X axis toward the saw blades 20 and 21.
First, the large module gear 6L and the R1 portion are simultaneously cut to a predetermined depth using the saw blade 20.2+ as shown in FIG.

測定の原理を応用すれば簡単に算出できる。Note that each saw blade 2 is located at the center o - o' of the large module gear 6.
The distance t up to 0.21 can be easily calculated by applying the principle of straddle tooth thickness measurement as shown in FIG.
すなわち距離ｔ＝またき歯厚×±＋０．５上記式中０．

揃える必要もない。As described in detail above, this invention is capable of removing most of the unnecessary parts of the teeth using two strips and serrations, so it can be cut into large modules in a shorter time compared to the conventional method of cutting with a gear cutter or the like. Rough machining of gears can now be performed, greatly improving work efficiency. In addition, it is possible to cut out unnecessary parts with less power, and it is economical with less tool wear compared to gear cutting machines, etc., and there is no need to replace tools every time the module is changed, so tools are required for each module. There's no need to arrange it.
