たタイミングプーリーの製造方法に関する。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention involves forming a metal plate into a cylindrical body with a drawn bottom by press working, and at the same time forming a tooth profile on the cylindrical part. The present invention relates to a method of manufacturing a timing pulley.
［従来の技術］
タイミングプーリーは、外周に歯形を有するプーリーで
あり、伝導用回転部として使用されている。従来かかる
タイミングプーリーの製造にあっては、一般に鋳造によ

る方法などにより行なわれていた。[Prior Art] A timing pulley is a pulley having teeth on its outer periphery, and is used as a rotating part for transmission. Conventionally, such timing pulleys have generally been manufactured by casting methods, or by cutting cast iron or round bars using a gear cutter.
しかるに、上記方法によれば、その製造作業が面倒で時
間がかかり生産性が悪く、そして軽量化が困難であり、
更に切削加工による場合には切屑が生じ材料に無駄が多
くなるといった問題がある。そこで、かかる問題点を解
決する方法として、１枚の金属板でタイミングプーリー

属板を、その外周を絞って皿状のリム部を形成し、この
リム部に歯形を形成した後、リム部を底面に対し垂直に
立ち上らせるといった方法がある（特開昭５７−５８９
４０号）。However, according to the above method, the manufacturing process is troublesome and time-consuming, resulting in poor productivity, and it is difficult to reduce the weight.
Furthermore, when cutting is used, there is a problem in that chips are generated and a large amount of material is wasted. Therefore, as a method to solve this problem, a method of manufacturing a timing pulley using a single metal plate has been considered.As a method, a dish-shaped rim portion is formed by squeezing the outer circumference of a single metal plate. However, there is a method in which the rim part is made to stand up perpendicularly to the bottom surface after tooth profiles are formed on the rim part (Japanese Patent Laid-Open No. 57-589).
No. 40).
［発明が解決しようとする問題点］
しかるに、上記方法によれば、歯形を形成したリム部を
垂直に立ち上らせたとき、リム部の開口端側の肉が残り
一方基部側には欠肉が生じたことになり、この結果歯形
に歪みが生じてしまい精度の良いタイミングプーリーを
得ることができないといった問題がある。[Problems to be Solved by the Invention] However, according to the above-mentioned method, when the rim portion in which the tooth shape is formed is vertically raised, the meat on the open end side of the rim portion remains, while the meat on the base side is missing. This creates a problem in that the tooth profile becomes distorted, making it impossible to obtain a highly accurate timing pulley.

The metal plate is then squeezed to form a bottomed cylindrical body having a cylindrical part perpendicular to the bottom surface, and at the same time, a tooth profile is formed on the cylindrical part by male and female teeth.

FIG. 3 is an exploded perspective view showing a metal plate 3 formed into a timing pulley by press working using the male die 1 and the female die 2. FIG. In the figure, the male type 1 has a structure in which a tooth portion 5 is formed on the outer circumferential surface of a cylindrical body 4 with a pitch corresponding to the required teeth of the timing pulley in the axial direction. Further, the female mold 2 is arranged on the inner circumferential surface of the cylindrical groove 6 at the same pitch as the tooth portions 5 of the male mold 1 in the axial direction, and when the cylindrical body 4 of the male mold 1 is fitted into the cylindrical groove 6, they are mutually connected. It has a configuration in which toothed portions 7 are formed to mesh with each other.
