形に特殊な設備を要し、金型費が高い等の欠点がある。Conventional toothed pulleys used for power transmission as described above are usually of a one-piece construction made of steel, aluminum alloy, etc., with teeth cut, or those that are integrally cast or forged. Otherwise, the cast iron rim has gears cut into it and is connected to cast aluminum spokes and bosses.However, as the outside diameter of the metal toothed pulley increases, the weight increases significantly. In addition, gears that cut gears have the disadvantage that they cannot be mass-produced and are expensive.Also, synthetic resin toothed pulleys have the disadvantage that the boss part is easily damaged due to the transmitted power, and dimensional changes due to temperature are large. There are also sintered and sheet metal parts, but sintered ones are heavy, sheet metal parts require special equipment to form the teeth, and mold costs are high. There is.
本発明の目的は、外周面に歯部を具えた合成樹脂製リム

リを提供するにある。The object of the present invention is to provide a toothed pulley which eliminates the above-mentioned drawbacks of the conventional method by embedding and fixing the outer edge of a sheet metal web having a shaft through hole in the center inside a synthetic resin rim having teeth on the outer circumferential surface. is to provide.
以下本発明の実施例を図面を参照して説明する。Embodiments of the present invention will be described below with reference to the drawings.

(Fig. 3) is effective. Instead of providing the annular portion 4 on the rim portion 1, the rim portion 1 may be made thicker in the radial direction as shown in FIG. 4, and a bent portion 1o may be formed on the outer periphery of the web 5 to be embedded and fixed. In addition, in order to reinforce the rim part 1 against the driving force of the toothed belt, if reinforcing ribs 12 (Fig. 1) are provided at the positions of the teeth 11 of the tooth part 2, the thickness of the rim part 1 can be reduced and the resin Materials can be saved and weight can be reduced. 13 is a punching hole for weight reduction of the web 5, 14 is a hole for attaching to a boss metal fitting or a shaft metal fitting, and 15 is a keyway.
第５図はリム部１と他物との干渉をさけるためウェブ５
の中央部分を一側に突出させて、軸取付位置をずらせた
例である。Figure 5 shows a web 5 to avoid interference between the rim part 1 and other objects.
This is an example in which the central part of the shaft is made to protrude to one side and the shaft mounting position is shifted.

都合である。In FIG. 6, a cylindrical portion 17 is formed by press working in order to securely fix a boss metal fitting 16 to the center portion of the web 5. A locking portion 18 protruding inwardly is cut out and formed on the cylindrical portion 17. This is the axial direction of the boss metal fitting 16/11519
to stop the rotation. FIG. 7 shows an example in which the boss fitting 16A is fixed to the web 5 with a bolt 20 inserted through the mounting hole 14. By providing the cylindrical portion 17 or the hollow hole 14 in this way, the web 5 can be commonly used for various boss fittings 16.16A that differ in dimensions and shapes such as shaft diameter and axial length. This is convenient for replacing toothed pulleys and reducing inventory.
