要し、加工部も多いという欠点があった。Furthermore, as a countermeasure to eliminate this drawback, as shown in Figure 8,
A method of reducing the number of cut parts by using cast metal was proposed. This product is manufactured by first manufacturing the blank shown in Fig. 8 (Pi) by casting, and then manufacturing the necessary parts, namely the through hole (1), the ■ shaped groove (
The pulley shown in Fig. 8(b) is obtained by cutting the plank, etc., and the disadvantage is that it takes a lot of man-hours to manufacture the plank and there are many processed parts.
この発明は上述の各欠点を解消し、プレス加工の省資源

た検数のＶ形状溝で、平型ベルト（８）が装着される。The present invention solves the above-mentioned drawbacks and provides a method of manufacturing a boob that facilitates processing and improves yield by utilizing the resource saving properties of press working. An embodiment of the present invention will be explained below with reference to FIG. In Fig. 4, (11) is a barrel-shaped slag, (5) is a side plate, (
11 is the h water passage into which the rotation shaft of the generator is inserted, (6) is the cylindrical part that protrudes in the axial direction from the outer circumference of the side plate (6), (7
) is a V-shaped groove formed by rolling on the outer circumference of the cylindrical portion (6), into which the flat belt (8) is attached.
次にこのようなプーリの製作方法について説明する。先

ーリの製作を完了する。Next, a method of manufacturing such a pulley will be explained. First, the slag (1) is attached to the side plate (61) as shown in Figure 4 (b).
The cylindrical part (6) that protrudes in the axial direction from the outer periphery of this side plate is drawn into a piece, and then a through hole (1) is formed based on the outer periphery.
Punch out. Finally, as shown in Figure 4, a plurality of ■-shaped grooves (7) are formed by rolling on the outer periphery of the cylindrical portion (6) so that a flat belt (8) can be attached thereto. Complete production.
即ち、この実施例のものでは、厚相であるスラグ（１１

、従来のものに比し、加工工程が少なくなり、且つ材料
の無駄がない。That is, in this example, the thick phase slag (11
After forming most of the boob by press working from 1, the outer periphery is rolled in the final process, which reduces the number of processing steps and saves material. There is no waste.
なお上側では、ブーりを発電機に装着するものを例示し
たか、その他の伝達機構部材にも使用可能であることは
勿論である。また上側では、プーリの側板（６）の内周

（１）を基準に外周を形成してもよい。Note that although the upper part shows the example in which the booby is attached to the generator, it is of course possible to use it for other transmission mechanism members. Moreover, although the upper side is exemplified as having a through hole (1) for mounting the rotating shaft on the inner peripheral rod of the side plate (6) of the pulley, the mounting hole does not have to pass through the pulley. Furthermore, on the upper side, the V-shaped groove (7) in the cylindrical part (6) of the pulley is shown as being formed on the right side of the cylinder* (6), but of course it may be formed in other positions, and The through hole (1) was punched based on the outer periphery, but
A through hole (1) may be punched out in advance 11, and the outer periphery may be formed based on this through hole (1).

に適合し得るプーリを提供できる効果がある。As described above, in the present invention, a slag with a predetermined capacity is formed by press working into a side plate and a cylindrical part protruding from the outer periphery of the side plate in the axial direction, and then the outer periphery of the cylindrical part is rolled. Since the grooves are formed with the number of ladles, the material yield is greatly improved compared to the conventional method, and the processing steps can also be significantly reduced, making it possible to provide pulleys that are compatible with Taisha production. be.
