Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は摩擦車に関し、詳しくはエラストマを成形素
材として成形された摩擦車の改良に関する。TECHNICAL FIELD The present invention relates to a friction wheel, and more particularly to an improvement of a friction wheel formed by using an elastomer as a molding material.
従来、無段変速装置として、第４図に示すように、二つ
の円板A,Bをその回転軸A1,B1を直交させて接触させ、か
つ、一方の円板Ａ表面に接触する他方の円板Ｂを軸方向
に移動可能とすることにより無段変速伝動可能とする装
置が知られている。Conventionally, as a continuously variable transmission, as shown in FIG. 4, two discs A and B are contacted with their rotation axes A 1 and B 1 being orthogonal to each other, and are in contact with the surface of one disc A. There is known a device capable of continuously variable transmission by making the other disc B axially movable.
上記のような摩擦を利用した無段変速装置は、円板A,B
の相互の接触面における摩擦係数の大小が伝動性能に大
きく影響するので、かかる観点より摩擦車の相互の接触
面A2,B2を材質的に摩擦係数の高いウレタンゴム、天然
ゴム、クロロプレンゴムなどエラストマにより形成され
ることがある。The continuously variable transmission that utilizes friction as described above is
Since the magnitude of the friction coefficient at the mutual contact surfaces of the two greatly affects the transmission performance, from this viewpoint, the mutual contact surfaces A 2 and B 2 of the friction wheels are made of urethane rubber, natural rubber, and chloroprene rubber, which have high friction coefficients. May be formed by elastomer.
しかしながら、前述したような無段変速装置において、
円板Ｂは他方の円板Ａ表面に対して一定の幅Ｓを有して
接触するため幅Ｓに応じた回転半径の相違により両者の
摩擦接触面には必ずスリップが生じており、このスリッ
プにより種々の弊害が生じるといった問題があった。However, in the continuously variable transmission as described above,
Since the disc B contacts the surface of the other disc A with a certain width S, a slip is always generated on the frictional contact surfaces of the two discs due to the difference in the radius of gyration according to the width S. However, there is a problem that various adverse effects occur.
即ち、摩擦車を表面摩擦係数が大きいエラストマで形成

記エラストマの硬度を高くするなどして表面摩擦係数を
低くすると、摩擦熱発生に原因する不都合は改善される
反面、伝達性能を良くするため両者の接触圧力を大きく
しなければならず、そのための機構が大掛かりとなり装
置の小型、軽量化を犠牲とせざるを得なくなるといった
問題があった。That is, when the friction wheel is made of an elastomer having a large surface friction coefficient, the transmission performance at the time of starting is improved even with a small contact pressure, but as the transmission speed increases, the contact surface has a proportional slip that cannot be avoided due to the mechanism. There is a drawback that the elastomer material melts due to heat generation, sticking occurs, and the service life is exhausted in an early stage, conversely, if the surface friction coefficient is lowered by increasing the hardness of the elastomer, Although the inconvenience caused by frictional heat generation is improved, the contact pressure between the two must be increased in order to improve the transmission performance, and the mechanism for that must be large, and the size and weight of the device must be sacrificed. There was such a problem.
ちなみに、第４図に示した装置につき、表１に示す素材
及び硬度の摩擦車により各使用条件にて走行試験を行な
ったところ表１右欄に示す結果となり、エラストマを素
材とする摩擦車については、耐用寿命、あるいは伝達性
能の向上の面で今一つ改良の余地が有ることが判明し
た。By the way, a running test was conducted on the device shown in FIG. 4 using friction wheels of the materials and hardness shown in Table 1, under the respective usage conditions, and the results shown in the right column of Table 1 were obtained. Has been found to have another room for improvement in terms of service life or transmission performance.
〔発明が解決する問題点〕 この発明は上記問題点に鑑み、摩擦車の機構上の避けら
れないスリップによる発熱等が確実に防止出来、しかも
伝達性能の良い摩擦車を提供することを目的としてなさ
れたものである。 [Problems to be solved by the invention] In view of the above problems, an object of the present invention is to provide a friction wheel that can reliably prevent heat generation due to unavoidable slip on the mechanism of the friction wheel and that has good transmission performance. It was made.
即ち、この発明の摩擦車はシリコンオイルと親和性を有
するエラストマに前記シリコンオイルを0.1〜10重量％
添加混合して成る混合物により成形されたことを特徴と
するものである。That is, the friction wheel of the present invention has an elastomer having an affinity with silicone oil, and the silicone oil is contained in an amount of 0.1 to 10% by weight.
It is characterized by being molded by a mixture formed by adding and mixing.
シリコンオイルは周知のように物質に低摩擦性を付与す
る素材として有用なことが知られている。As is well known, silicone oil is known to be useful as a material that imparts a low friction property to a substance.
従って、このシリコンオイルをエラストマ材料に均一混
合すれば、その添加量を調整することによりエラストマ
材料の硬度を一定に保ったままその表面摩擦係数の高低
を調整することが可能となる。Therefore, if this silicone oil is uniformly mixed with the elastomer material, it is possible to adjust the level of the surface friction coefficient thereof while keeping the hardness of the elastomer material constant by adjusting the addition amount.
しかしながら、シリコンオイルとエラストマ材料として
は必ずしも化学的あるいは物理的に作用し、あるいは混
合可能なものばかりとは限らず適合を誤るとかえって成
形体の強度等物理的性質を低下させることとなる。However, the silicone oil and the elastomer material do not always act chemically or physically, or are not always mixable, and if they are not properly matched, the physical properties such as strength of the molded product are deteriorated.
そこで、エラストマ材料としては、シリコンオイルと親
和性の有るものであって、成形後の機械的強度が優れ、
かつ、適度に硬度を選択出来るものが用いられる。Therefore, as an elastomer material, it has affinity with silicone oil and has excellent mechanical strength after molding,
In addition, a material whose hardness can be selected appropriately is used.
このようなエラストマ材料としては、ウレタンゴム、天

ルゴム（BR）、クロロプレンゴム（CR）、アクリルニト
リルブタジエンゴム（NBR）、クロロスルフォン化ポリ
エチレンゴム（CSM）などが挙げられる。Such elastomer materials include urethane rubber, natural rubber (NR), styrene butadiene rubber (SBR), butyl rubber (BR), chloroprene rubber (CR), acrylonitrile butadiene rubber (NBR), chloro sulfonated polyethylene rubber (CSM). ) And the like.
また、シリコンオイルとしては、ポリシロオキサンオイ
ル等が適しており、特に下記の化学式で示される粘度50
〜500c/sのポリジメルシロオキサンオイルが好適であ
る。Further, as the silicone oil, polysiloxane oil or the like is suitable, and particularly, the viscosity shown by the following chemical formula 50
Polydimer siloxane oil of ~ 500 c / s is preferred.
本発明において、シリコンオイルの添加量を0.1〜10重
量％とする理由は、後述の試験結果より明らかなように
0.1重量％より少ないと充分な低摩擦性が得られなくな
り、10重量％より多いと、伝動性能及び機械的強度の低
下が生じ不都合だからである。 In the present invention, the reason why the addition amount of silicone oil is 0.1 to 10% by weight is as clear from the test results described later.
If the amount is less than 0.1% by weight, sufficient low friction cannot be obtained, and if the amount is more than 10% by weight, the transmission performance and mechanical strength are deteriorated, which is inconvenient.
次に、この発明の実施例について説明する。 Next, an embodiment of the present invention will be described.

Was heated to 90 ° C., and then polysiloxane oil and a cross-linking agent, 3,3′-dichloro-4,4′-diaminodiphenylmethane, were mixed, and the mixture was heated in a preheated friction wheel. It was poured into a mold or was baked and adhered to the core.

焼付体とされ、有効直径Ｄが125mm、エラストマ層の厚
さＨが3mmのものである。The formed friction wheel is a friction wheel A whose contact surface is the disk surface.
As shown in FIG. 1, it is a baked product on the surface of the metal base 1 having an effective diameter D of 125 mm and an elastomer layer thickness H of 3 mm.

結果が得られた。In Example 1 above, running tests were conducted on various friction wheels A and B molded by changing the amount of polysiloxane oil added to 0 to 10% by weight, and the test results shown in FIG. 3 were obtained. It was

低下する一方、引張強さ、及び伝達性能の低下はそれ程
著しくなく、添加量６重量％程度までは、この傾向が続
くことが判明した。That is, in FIG. 3, 0.1% polysiloxane oil was added.
It was found that the friction coefficient and the degree of friction drastically decreased from the one added by weight%, but the tensile strength and the transmission performance were not significantly decreased, and this tendency continued until the addition amount was about 6% by weight.
なお、６重量％を超え、10重量％程度の添加量となると

に引張強さの低下が著しくなるので、添加量の範囲を0.
1〜10重量％好ましくは0.1〜８重量％の範囲とされるこ
とが良いことが判明した。When the amount of addition exceeds 6% by weight and about 10% by weight, the improvement of the friction coefficient and the degree of friction is almost the limit, whereas the reduction of the tensile strength is particularly remarkable, so the range of the addition amount is 0 .
It has been found to be good to set it in the range of 1 to 10% by weight, preferably 0.1 to 8% by weight.
