同時に所定深さになるまで切削する。 Therefore, when rough machining the gear material 6, the indexing board 5 is first set according to the module and gear, and when the setting is completed, the gear material 6 is mounted and fixed on the indexing board 5. Next, operate each handle 8, 9 to move each slide base 10, 11 an equal distance l from the center line O-O' of the gear material 6 in the Y-axis direction, and move each saw blade 20, 21 to the fourth position. 2l as shown
In this state, the drive motors 16 and 17 rotate the saw blades 20 and 21, and the feed motor 3 moves the slide base 4 and the indexing board 5 thereto.
The gear material 6 attached through the gear is moved along the X-axis toward the saw blades 20 and 21, and first, the saw blades 20 and 21 simultaneously cut the gear 6L 1 and R 1 portions to a predetermined depth as shown in FIG. Cut until.

とができるようになる。 Note that each saw blade 20,
The distance l to 21 can be easily calculated by applying the principle of straddle tooth thickness measurement as shown in FIG. That is, distance l = straddle tooth thickness x 1/2 + 0.5 In the above formula, 0.5 is the addition of the finishing allowance.
Also, the module of gear material 6 is 10, the pressure angle is 20°,
When the number of teeth is 45, l = 85, 725mm (including machining allowance of 0.5mm) depth of cut h
= 21, 25 mm, and the indexing angle γ is γ = 360 / number of teeth = 360 / 45 = 8° Once the cutting of L 1 and R 1 shown in Fig. 4 was completed, the gear material 6 was rotated by an angle of 8° using the indexing machine 5. After that, proceed to the saw blades 20 and 21 again to cut L 2 and R 2. By repeating the above operation, a triangular cutting block 6a is cut out from when L 7 adjacent to the cutting groove R 1 is cut. Thereafter, the rough machining of the gear material 6 is completed by cutting out the cutting block 6a over the entire circumference. When the rough machining of the gear material 6 is completed, the gear material 6 is removed from the indexing machine 5 and gear cutting is performed using a gear cutting machine, thereby making it possible to complete the gear cutting work of large modular gears in a short time. .

ユール毎に工具を揃える必要もない。 As described in detail above, this invention is capable of cutting most of the unnecessary parts of the teeth using two parallel band saw blades, compared to the conventional cutting method using a gear cutter or the like. This enables rough machining of large modular gears in a short time, 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 change tools every time the module changes, so tools can be changed for each module. There's no need to arrange it.
しかも切削反力が小さいため機械自体の剛性を
