【発明の詳細な説明】
本発明は自動車のエンジンにおいて、各種補機の駆動に
使用される板金製のポリＶプーリに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a poly-V pulley made of sheet metal used for driving various auxiliary machines in an automobile engine.
従来の板金製のポリＶプーリについては、第４図示の様
な特開昭５６−１４３８６３号「動力伝達用ポリＶプー
リの製作方法」の明細書に記載のごとく、一枚の鈑金よ
り肉厚の周壁部２０を形成し、周壁面にポリＶベルトと
係合するポリＶ溝２１を形成し、周壁部２０の両端部に
左右一対のフランジ２２及び２３を設け、駆動軸（図示
路、）に取付ける側壁部２４よりなっている。Regarding conventional poly V pulleys made of sheet metal, as shown in the specification of JP-A-56-143863 ``Method for manufacturing poly V pulleys for power transmission'' as shown in Figure 4, the thickness is thicker than that of a sheet metal sheet. A peripheral wall portion 20 is formed, a poly V groove 21 that engages with a poly V belt is formed on the peripheral wall surface, a pair of left and right flanges 22 and 23 are provided at both ends of the peripheral wall portion 20, and a drive shaft (path shown) is formed. It consists of a side wall portion 24 that is attached to.
然しこの様なポリＶプーリは、大きな伝達トルクＴが駆
動軸、側壁部からポリＶ溝と伝達されると鈑金がほぼ１
８０°折曲げられたフランジ２２の先端部２２ａに大き
な荷重がかかり、例えばこの集中荷重により２２ａの折
線に示すごとく、この場所より破損するという欠点があ
った。However, with such a poly V pulley, when a large transmission torque T is transmitted from the drive shaft and side wall to the poly V groove, the sheet metal becomes almost 1
A large load is applied to the tip 22a of the flange 22 bent at 80 degrees, and this concentrated load causes the flange 22 to break at this point, for example, as shown by the fold line 22a.
本発明は前記欠点を改良したもので、鈑金より形成する
ポリＶプーリにおいて、駆動力を伝達する側壁部側のフ
ランジにおいて折曲げ角度を従来の１８０°より９０°
と小さくし、かつフランジの外径を、はぼＶ溝の外周径
と同様とし、ベルトはずれ防止用のリングを溶接等によ
りＶ溝最端部に固着したものである。The present invention improves the above-mentioned drawbacks by changing the bending angle of the flange on the side wall side that transmits driving force to 90° from the conventional 180° in a poly V pulley made of sheet metal.
The outside diameter of the flange is made to be the same as the outside diameter of the V-groove, and a ring to prevent the belt from slipping is fixed to the end of the V-groove by welding or the like.
この様なポリＶプーリは、
（１）動力伝達側の側壁部のフランジ部を約９０゜に折
曲げて、後ポリＶ溝が形成されておるために、この折曲
げ部のメタルフローにまったく無理がなく、大きな１〜
ルクがかかつても破損しない。This type of poly V pulley has the following features: (1) The flange part of the side wall on the power transmission side is bent at approximately 90 degrees and a rear poly V groove is formed, so there is no metal flow at this bent part. No wonder, big 1~
It will not be damaged even if it gets bent.
（２） ヘル１へはずれ防止用リングをポリＶ溝の周
壁部端部に溶接固着する。このために従来技術のごとく
フランジ部を高く盛り上げる必要がなく、成形工程が大
巾に簡単、短縮化出来るものである。(2) Weld and secure the anti-removal ring to the edge of the peripheral wall of the poly V groove on Hell 1. For this reason, there is no need to raise the flange portion as high as in the prior art, and the molding process can be greatly simplified and shortened.
（３）板金製ポリＶプーリであれば、いかなる種類のも
のにも一方又は双方にベルトはずれ防止用リングを固着
すればよく、形態をとれず且つ安価・容易にできるとい
う特徴がある。(3) If it is a poly V pulley made of sheet metal, a ring for preventing belt slippage may be fixed to one or both of any type of pulley, and the pulley has the characteristics that it does not take any shape and can be made inexpensively and easily.
更に前記ヘルドはずれ防止用リングにかえて、使用材料

荷重がかからないために、エンジンルームの温度に耐え

ことも可能である。Furthermore, instead of the ring for preventing the heddle from slipping off, in order to save the materials used, a plurality of arc-shaped metal pieces approximately equal to the outer diameter of the poly-V pulley can be arranged to form a ring shape and fixed by welding. Since almost no load is applied to the ring for preventing belt slippage, it can withstand engine room temperatures. It is also possible to adhesively fix a heat-resistant resin to the side surface of the poly V-boo.

ラにてＶ＃形成後、。In Fig. 1, reference numeral 1 is a silver-gold material, which is formed into a cup shape by press forming.The thickness of the peripheral wall portion 2 is the same as that of the silver-gold material 1, but the thickness of the side wall portion 3 may vary depending on the shape of the cup or the type of construction method. In some cases, the thickness may be reduced. Furthermore, the shape of the side wall part is J a
+ or 3b, and 2a is a cup-shaped outer peripheral surface. In addition, depending on the installation condition of the main pulley, the side wall portion is formed into an inwardly overhanging shape as shown in 3b. Next, the outer peripheral surface 2a of the cup is processed by a rolling roller 5 to form a poly V groove 4. Next, rings 6 and 7 for preventing dislodgement of the helmet 1, which were manufactured separately in advance, are spot welded 6a and 7a to both ends 2b and 2C of the peripheral wall 2, respectively. The outermost diameter portions 6b and 7b of the ring for preventing heald from coming off are approximately 3 to 5 mm larger than the tip portions 4a, 4b, . . . of the peaks of the poly V groove. 1o is after press-molding the silver-gold material and forming a V# with a rolling roller.
