本発明は炭素繊維（以下ＣＦという）と綿や合成繊維な
どの有機質繊維布帛を補強用繊維として用いた繊維強化
プラスチックス製歯車に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gear made of fiber-reinforced plastics using carbon fiber (hereinafter referred to as CF) and organic fiber cloth such as cotton or synthetic fiber as reinforcing fibers.

しも充分で満足のいく歯車とは云えない状況にある。Monomer-cast nylon gears and phenol resin gears made of cotton cloth impregnated with phenolic resin are well known as relatively large gears that can prevent noise and eliminate oil lubrication. Although the oil-free effect is quite effective, its strength is significantly inferior to that of metal cars, and when used under high-speed, high-load conditions, heat generation and heat storage may cause a decrease in strength and noise prevention effect. Furthermore, various problems such as increased wear occur, and the gear cannot necessarily be said to be sufficient or satisfactory.

つとして指摘されている。As a fiber-reinforced plastic gear that compensated for these drawbacks, a gear using CF as a reinforcing fiber has been developed, as shown in Japanese Patent Publication No. 54-3643. Compared to the conventional plastic gears mentioned above, it is extremely strong (and requires no lubrication/
Although it has various properties such as excellent friction and wear characteristics when used as a W gear, it essentially generates noise similar to gears made of metal materials, and its noise prevention effect is not sufficient. Furthermore, when a gear is made from a laminated material with a thickness of more than 20 parts, air bubbles and distortions are likely to remain inside the laminated material, which often causes a decrease in mechanical strength. Furthermore, since CF reinforced plastic materials have high hardness, there are major problems in their secondary workability, and in particular, their poor gear cutting workability is their biggest drawback. On the other hand, in the method of manufacturing gears made of CF reinforced plastics, for example, as shown in Fig. 1, OF rugs are laminated and molded in a manner such that the fiber arrangement angle of the OF carpet is sequentially changed at a constant angle, and then processed into gears. By doing this, a method is used to create a gear with the shape shown in (1) in Figure 1, but (2)
It has also been pointed out that one of the problems is that a large amount of CF is lost as shown in FIG.

を完成した。Therefore, the present inventors have conducted intensive studies to obtain gears made of CF-reinforced plastics that have improved the above-mentioned problems.
They discovered that an excellent gear can be obtained by making a laminated molding material by combining the materials and cutting the material, and completed the present invention.

浸したものなどを挙げることが出来る。The gist of the present invention is that resin-impregnated unidirectionally aligned CF tapes are laminated as shown in FIG. A woven or non-woven organic fiber material impregnated with a resin is formed into a circularly laminated disk body so that the orientation direction of the fibers is radial from the center of the circle to the outer circumferential direction Kfi, as shown in Fig. 4. A fiber-reinforced plastic gear having a cross-sectional structure as shown in FIG. 4 is obtained by laminating a plurality of layers of fabric and cutting a hardened disk-shaped gear material. The unidirectionally aligned CF tape used in carrying out the present invention is a tape made of CFs aligned in one direction and impregnated with matrix resin, or a reinforcing material such as scrim cloth is attached to this tape. For example, a tape-like material made of a cloth made of CF tape wefts aligned in one direction and CF or organic fibers impregnated with a matrix resin can be cited.

来るが最も好ましいものとしては綿布である。On the other hand, the organic fiber fabrics used in carrying out the present invention are natural fibers such as cotton and hemp, synthetic fibers such as vinyl alcohol fibers, polyamide fibers, polyethylene terephthalate fibers, acrylic fibers, and strong human silk. Examples include woven or non-woven fabrics made of chemical fibers or semi-synthetic fibers, etc. alone or of two or more types, but cotton fabric is the most preferred.

Thermosetting resins and the like can also be used.

もｃｒの混率を増すほど効果も大きくなる。In the present invention, the mixing ratio of the CY tape-like material and the organic fiber fabric varies depending on the purpose of use of the gear, but it reduces heat accumulation during use, suppresses temperature rise at the tooth tip, and improves only the noise prevention effect. If the purpose is to achieve this, it is preferable that the mixing ratio of cy be at least 3 Vot% of the total reinforcing fibers, and the greater the amount, the greater the effect. In addition, if the purpose is to increase strength and self-lubricating effect, CF
The mixing ratio of all reinforcing fibers is preferably at least 10 VoLq6, preferably 20 Vot- or more. In this case as well, the effect becomes greater as the cr content increases.
しかしながらＣＦの混合比率があまり多くなりすぎると
積層成型性、切削歯切り勢の二次加工性が著しく低下す
るので適度に止めてお（ことが必要である。However, if the mixing ratio of CF becomes too large, the lamination moldability and the secondary workability of the cutting gear force will be significantly reduced, so it is necessary to keep it at an appropriate level.
すべての性質の面から採るべきＣＦの比率は２０〜８０

The range of ot- is good.

勝れているなど種々の利点を有している。Although the gear of the present invention has better cutting workability such as gear cutting than gear materials using only CF as reinforcing fibers, it contains defects such as voids inside, and its strength is also superior. Also, it has a great noise prevention effect when using gears, and there is no sound produced by metal gears. It has various advantages such as sufficient self-lubricating properties.
