However, since the sterilized pulley is made of a soft iron plate, the type of processing is exclusively press work. Conventionally, the manufacturing method for these shapes was to press the material to form a circumference parallel to the axis, and to form a circular planar material from a shallow dish shape to a deep dish shape at the same time as a tooth mold. This is done in combination with other tasks. Toothed pulleys formed through such multi-step press work cannot have high precision in the tooth shape itself, and the tooth shape is only used as a resistor when transmitting rotation. Therefore, it was considered impossible to use gears as a purpose.

Further, as described above, the multi-stage pressing operation causes a change in the material at the pressed location. That is, the hardening phenomenon of the material occurs due to the bending process, which results in damage and deformation of the resulting product during use. In this way, the purpose of use of the toothed pulley provided around the circumference is limited to simply being used as a resistor to prevent slipping.

After finishing the rough machining process (2), in the next main machining process, a rough machining process is performed to form a rough machining part that connects to the inner end of the tooth profile (5), which was formed longer than the desired tooth width in the previous process, that is, to the width part (7). At the same time as crushing the end portions and forming the desired tooth width of the tooth shape (5), corner portions of each unit tooth shape (5) compressed and formed in the mold processing step (2) in the tooth shape (5). This process is performed using a press to increase the accuracy of the process. This is the main purpose of this invention, and in order to establish the shape of the width part (7) and the end of the tooth pattern (5) at the connection point, the tooth pattern (5) formed by crushing the starting end of the tooth pattern (5) is crushed. m
A right-angled curved line (
Process so that e) is formed. This is a tooth pattern (5)
In this case, the accuracy must be uniform over the entire length of the tooth width forming the tooth profile (5). The width portion (7) of this tooth pattern (5) is formed as the starting end of the tooth pattern (5) because the flat part does not require high precision except for the diameter dimension. The crushed portion is changed to the outer periphery of the width portion (7). In this way, the once formed tooth pattern (5) is crushed and a right-angled bend line (
e) is established, and the starting end of the tooth pattern (5) formed by the right-angled bending line (e) can be formed into an end surface such as a cross section of the tooth pattern (5). In this way, this main processing step (
3) is the high precision production of the end of the tooth pattern (5) that connects with the width part (7) and the precision machining of the entire tooth pattern (5), and then the next finishing step (4) is the manufacturing of the tooth pattern (5) with high precision. 5) is intended to improve the accuracy of the corner portions. The device used in this processing step (3) is substantially the same as the device used in the mold processing step (2).
