む平ベルトに関するものである。[Detailed description of the invention] (Field of industrial application) This invention is mainly used for belts for twisters (twisting machines), which have severe surface wear, as well as for transmission and transportation in ticket vending machines, ticket inspection machines, money changers, vending machines, etc. This invention relates to a flat belt that is thin and has excellent bending resistance on the extension side and has high abrasion resistance on the extension side surface when used with a small pulley diameter.

帆布３を貼着した平ベルトが用いられている。(Prior art) Thin flat belts used with small pulley diameters, including twisters and conveying banknotes, coins, and kits, are usually made of stretched resin film or canvas as a tensile member 1, as shown in Figure 4. A so-called tape-like tensile material 1 is impregnated with the elastic material 1 and other cloth or leather 10 is laminated on the top and bottom, or a cord-like tensile material 1 is embedded in the elastic material 2 as shown in FIG. A flat belt with canvas 3 attached to prevent tearing is used.

弾性体層を厚くすると小プーリによる屈曲疲労が
起こるなどの問題がある。 However, in the case of a laminated flat belt as shown in FIG. 4, the belt thickness is increased, and the tension member becomes fatigued due to bending by the small pulleys. Furthermore, although the belt with the structure shown in Figure 5 has good bending fatigue resistance, it has the disadvantage that the belt surface wears and its life is shortened, and if the elastic layer on the belt surface is made thicker, bending fatigue due to the small pulleys will occur. There are problems such as.

く、表面の摩耗が著しい。 For example, when used as a twister, as shown in Figure 6, each pulley with a small diameter should cross each other.
Wrap flat belts B 1 and B 2 between P 1 , P 2 , P 3 and P 4 ,
In this crossed state, the filament F is rotated at high speed in the direction of the arrow, passed between both belts B 1 and B 2 from below, and twisted by the driving force of both belts. There is severe cross contact and the surface wear is significant.
といつて、ベルト厚を厚くすると、プーリが小径
のため屈曲性が低下する。However, when the belt thickness is increased, the pulley has a small diameter, which reduces the flexibility.

プーリ径での使用を可能ならしめることを目的と
したものである。(Problems to be Solved by the Invention) The present invention addresses the above-mentioned circumstances and improves the abrasion resistance of the belt surface by incorporating a body abrasion material into the elastic body surface of the thin flat belt. The purpose is to enable use with small pulley diameters.
（問題点を解決するための手段）
しかして、上記目的に適合する本考案の特徴と

部に粒子径が0.5〜30μの範囲にある粉末よりなる
耐摩耗材を20〜40重量部混入せしめることにあ
る。(Means for Solving the Problems) The present invention, which satisfies the above objectives, is characterized by embedding the tensile-resistant ropes in parallel in an elastic body, and providing a longitudinal tear-preventing canvas layer on the back side. In the flat belt formed by pasting, 20 to 40 parts by weight of an abrasion resistant material made of powder having a particle size in the range of 0.5 to 30 μm is mixed into the surface layer of the elastic body.

よりなる縦裂き防止層３が貼着されている。 FIG. 1 shows an example of a flat belt according to the present invention,
In the figure, a is a flat belt, 2 is NR (natural rubber), CR (chloroprene rubber), SBR (styrene rubber),
butadiene rubber), NBR (nitrile rubber), IIR (butyl rubber), CSM (chlorosulfonated polyethylene), H-NBR (hydrogenated nitrile rubber),
An elastic body made of a single material such as CHM (epichlorohydrin rubber), ACM (acrylic rubber), or a blend of these as appropriate, or a resin material such as polyurethane. Rope tension members 1 with low elongation and high strength selected from glass fiber, steel wire, etc. are buried in parallel, and a vertical tear prevention layer 3 made of woven fabric such as canvas or lateral sag is pasted on the back side. It is worn.
そして、上記の如き構成において弾性体２の表
面に更に本考案の要部を構成する耐摩耗性材４が
混入されている。 In the above structure, the surface of the elastic body 2 is further mixed with a wear-resistant material 4, which constitutes the main part of the present invention.
この耐摩耗性材４は前述の如く粉末の大きさが
粒子径0.5〜30μ程度の珪素、窒化珪素などのセラ
ミツクパウダー、アルミナ、からなり、弾性体
100重量部に対して20〜40重量部混入される。 As mentioned above, this wear-resistant material 4 is made of ceramic powder such as silicon or silicon nitride, or alumina, with a particle size of about 0.5 to 30 μm, and is made of an elastic material.
It is mixed in 20 to 40 parts by weight per 100 parts by weight.
次に、平ベルト弾性体表面に耐摩耗材の粒子径
ならびに混入割合を変えてベルトの性能を比較実
験した結果を述べる。 Next, we will discuss the results of a comparative experiment on the performance of the belt by changing the particle size and mixing ratio of the wear-resistant material on the surface of the flat belt elastic body.
（実施例）
粒子径10μの炭化珪素を弾性体100重量部に対
して40重量部を表面に混入した厚み1.3×幅８mm
×長さ230mmの平ベルトを作成し、何れも38mmφ
の駆動プーリ、従動プーリ間に巻掛け、20W、軸
荷重20Kgｆ、8000R／Ｍで500HRS走行させ第２
図、第３図の結果を得た。(Example) 40 parts by weight of silicon carbide with a particle size of 10 μ per 100 parts by weight of the elastic body was mixed on the surface, thickness 1.3 x width 8 mm.
×Create a flat belt with a length of 230mm, each with a diameter of 38mm
Wrap it between the driving pulley and driven pulley, run 500HRS at 20W, axial load 20Kgf, 8000R/M, and the second
The results shown in Fig. 3 were obtained.
この結果、耐摩耗材を40重量部混入することに
よりベルト耐摩耗性が従来の摩耗材を混入しない
場合より約2.5倍向上していることが判つた。し
かし、粒子径を大きくすると第３図の如くベルト
の屈曲により炭化珪素が弾性体より脱落するため
却つて耐摩耗性は低下する。これはアルミナにつ
いても同様の結果が確認された。 As a result, it was found that by incorporating 40 parts by weight of the abrasion resistant material, the belt abrasion resistance was improved by about 2.5 times compared to the conventional case in which no abrasion material was mixed. However, when the particle size is increased, the silicon carbide falls off from the elastic body due to bending of the belt, as shown in FIG. 3, so that the wear resistance actually decreases. Similar results were confirmed for alumina as well.
また、混入量については、第２図からは下限は
20重量部であり、一方、上限は60重量部でも良い
ように感じるが、第４頁最下行にも記載する如く
混入割合が増加すると耐屈曲性が低下することも
勘案し、上限を40重量部に抑え、20〜40重量部に
限定することにより平ベルトとして好ましい耐摩
耗性、耐屈曲性を発揮することが分かつた。 Also, regarding the amount of contamination, from Figure 2, the lower limit is
20 parts by weight, and on the other hand, I feel that the upper limit is 60 parts by weight, but as stated in the bottom line of page 4, the bending resistance decreases as the mixing ratio increases, so I set the upper limit to 40 parts by weight. It has been found that by limiting the amount to 20 to 40 parts by weight, a flat belt can exhibit preferable abrasion resistance and bending resistance.
これらの結果、混入するセラミツクパウダーは
粒子径0.5μ〜30μ、混入量20〜40重量部混入する
ことが好適であることが知見された。 As a result, it has been found that the ceramic powder to be mixed has a particle size of 0.5 μm to 30 μm and is preferably mixed in an amount of 20 to 40 parts by weight.
次にガラス繊維、カーボン繊維を３〜30重量部
混入し、同様の実験を試みたところ、大筋におい
て前記セラミツクパウダーと同様の結果を得たが
弾性体内部での分散状態が悪く、塊状になり、良
好な結果は得られず、やはり、粉末状にするのが
好ましいことが分かつた。 Next, when we mixed 3 to 30 parts by weight of glass fibers and carbon fibers and tried a similar experiment, we obtained results that were generally similar to those of the ceramic powder, but the state of dispersion inside the elastic body was poor, resulting in lumps. However, good results were not obtained, and it was found that it is preferable to form the powder into a powder.
