り、その将来性が宿望されている。 A poly V pulley with multiple wavy grooves has a wider contact area with the V belt than a single V groove pulley, so
Excellent rotation transmission power. Therefore, the height of the V-groove can be reduced, and the diameter and distance between the pulleys can be reduced, making it possible to reduce the size and weight. It also has several advantages, such as the ability to interpose a number of pulleys between the multi-threaded V-belts stretched between the pulleys and drive them simultaneously, and its future prospects are promising.

ツチ間隔が不揃いになるという欠点があつた。 As a prior art related to a method for manufacturing a poly V pulley, the circumferential wall of the cup-shaped material is preformed on the outer surface side using a preforming roller into a corrugated cross-sectional shape having a plurality of troughs, and then the circumferential wall of the cup-shaped material is This is a method of forming into a predetermined poly V groove by compression processing in the axial direction and rolling processing using a rotary forming roller, and there is a method in which a waveform is formed in preliminary formation. However, even though the distance between the polygon grooves is narrow, it is necessary to use thicker material to provide strength.
Processing material during roller forming is unstable (final pitch
3.56), the critical pitch spacing was uneven, which was a drawback.

つている。 Further, as a prior art, there is also Japanese Patent Publication No. 11817/1983. This is a method that requires the steps of forming a sinusoidal shape, a step of forming a meandering shape, and a step of forming a poly V groove.The material is made thicker and the inner surface of the peripheral wall is finally formed to be flat. be. However, the disadvantage of this method is that the processing steps are complicated.

９，…，９が刻設される。 Fig. 3 shows that the material after the first step is rotated in the direction of arrow R1 , and 7 is a scraping roller that presses the material forward in the direction of arrow F1 so that the material after the first step is rotated. Although not shown, at this time, the outer surface of the cup-shaped disc part 8a is fitted into the lower female mold, and the inner surface is rotated with the upper male mold pressing the upper male mold to an extent that it is not compressed and the lower part being completely pressed. do. The peripheral wall portion 8b of the cup-shaped material is cylindrical with no polygrooves formed yet, so it has a considerable height, and each protrusion ring 7a on the surface of the scraping roller 7,
...The interval between 7a has also become wider. Protrusion ring 7
A, . . . , 7a are like ring stripes with sharp angles like the tip of a nail protruding in multiple layers. Therefore, when it is pushed into the outer surface of the cup-shaped peripheral wall portion 8b, slotted polygrooves 9, . . . , 9 are cut into the outer surface of the peripheral wall portion 8b.

FIG. 4 shows the material 8 after the second step obtained in this way in the axial directions A 3 and A 4 , and the upper mold 10
and the lower female die 11. This is compressed to create a wall thickness for the poly V groove to protrude, and the feature is that the frayed pitch is compressed to the finished pitch. The outer surface of the circumferential wall is compressed into a corrugated shape 12, while the inner surface of the circumferential wall is compressed into a flat 13, which is the third step of the method according to the invention.

部５が残在する。 In FIG. 5, the material 14 obtained in the third step is rotated as shown by the arrow R2 , and at this time the polygroove forming roller 15 is pushed forward in the direction of the arrow F2 . At this time, although not shown, the material 14 is gripped from above and below to the extent that it is not compressed in the same manner as in the second step, and is rotated as described above. The mold has a narrow pressure on the mounting surface, and the groove is held in the upper and lower molds with a predetermined dimension. The outer surface of the peripheral wall of the material 14 is
The wave shape is expanded by the poly V protrusions 15a, . . . , 15a of the poly groove forming roller 15 to form desired poly V grooves 16, .
