この発明は、■ベルト式無段変速機等に用いられる伝動
Vベルトに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a power transmission V-belt used in belt-type continuously variable transmissions and the like.

なく配列して設けた構成にする。This conventional source has a layered endless band formed by layering a plurality of endless bands, and a large number of V blocks that come into frictional contact with the inner circumferential surface of the innermost endless band are attached to the layered endless band along its length. The structure is such that they are arranged without any gaps in the direction.
そして、かかる伝動Vベルトは、■ブロックの両端傾斜

渡される。The power transmission V-belt is stretched across the briny booley and the secondary boley by frictionally engaging the inclined surfaces at both ends of the block with the V-groove opposing surfaces of the briny boley and the secondary boley.
(発明が解決しようとする課題)
しかしながら、このような従来の伝動Vベルトにあって
は、表面処理を施すことのない薄帯高張力鋼を積層する
ことによって、エンドレスバンドとするものとなってい
た為、積層された各薄帯高張力鋼間の摩擦係数が大で、
かつ、摩擦係数の大きさも局所的に異なることで、動力

均一に付加され、上記薄帯高張力鋼、ひいてはエンドレ
スバンド全体の疲労寿命が短くなるという問題があった
。(Problem to be Solved by the Invention) However, in such conventional power transmission V-belts, an endless band is created by laminating thin strips of high-strength steel without surface treatment. Therefore, the coefficient of friction between each laminated high-strength steel ribbon is large.
In addition, because the magnitude of the friction coefficient differs locally, excessive frictional shear force is unevenly applied to the high-strength steel ribbon during power transmission, causing damage to the high-strength steel ribbon and, by extension, to the entire endless band. There was a problem that the fatigue life was shortened.
また、特開昭59121254号公報には、■ベルトが
常時通過する所定の箇所に、潤滑油をI1i射するノズ
ルを設け、■ベルトの層状エンドレスバンドを潤滑する
ことにより、■ベルトの発熱及び摩耗を抑制する内容が
示されている。In addition, Japanese Patent Application Laid-Open No. 59121254 discloses that (1) a nozzle is provided to spray lubricating oil at a predetermined location where the belt always passes; The contents to be suppressed are shown.
しかしながら、層状エンドレスバンドを構成する各バン
ドの接触面同士は隙間なく密に重ね合せられている為、
層状エンドレスバンドの全体外表面こは潤滑油が供給さ

記同様に、積層された各薄帯高張力鋼間の摩擦係数は大
となる。However, since the contact surfaces of each band that make up the layered endless band are closely overlapped without any gaps,
Even if lubricating oil is supplied to the entire outer surface of the layered endless band, no lubricating oil is supplied between the contact surfaces of each band, and as above, the coefficient of friction between the laminated high-strength steel strips is large. becomes.
この発明は、このような従来の問題に着目してなされた
もので、層状エンドレスバンドを有する伝動Vベルトに

とした。That is, a plurality of endless bands are densely stacked in layers to form a layered endless band, and a large number of V blocks that come into frictional contact with the inner circumferential surface of the innermost endless band are arranged in the endless band of the layer without gaps in the longitudinal direction. In the power transmission V belt, which is used by frictionally engaging the inclined surfaces at both ends of the V block with the opposing surfaces of the V grooves of the boleys, a low friction coefficient treatment layer is formed on the surface of each band constituting the layered endless band. This means that it is characterized by the fact that
