本考案は平形ベルトの全周にわたりＶ形ブロツ
クを取り付けたＶ形ブロツクベルト、特にベルト
とＶ形ブロツクとの取付構成の改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to a V-block belt in which a V-block is attached over the entire circumference of a flat belt, and particularly to an improvement in the attachment structure between the belt and the V-block.
近時、自動車用、農業機械用を始めとしてベル
トに高馬力を伝動させることが時代の趨勢として
強く要求されているが、ベルトに高馬力を伝動さ
せようとすれば大きな側圧と、大きな張力に耐え
る高負荷伝動ベルトが必要となつてくる。 Recently, there has been a strong demand for belts to transmit high horsepower in applications such as automobiles and agricultural machinery, but in order to transmit high horsepower to belts, large lateral pressure and large tension are required. A power transmission belt that can withstand high loads will be needed.
ところが、従来のこの種ベルトは、主にゴムで
構成されているため耐側圧性に難があり、伝達可
能な容量におのずから制約を有していた。 However, since conventional belts of this type are mainly made of rubber, they have difficulty in resisting lateral pressure, and naturally have limitations on their transmittable capacity.
そこで、最近、かかるゴムベルトに代わる高負
荷伝動ベルトが種々考案されているが、その１つ
にボルトでＶ形ブロツクを平ベルト上に止める方
式のものがある。 Recently, various high-load power transmission belts have been devised to replace such rubber belts, one of which is a type in which a V-shaped block is fastened onto a flat belt using bolts.
このものは、そのブロツクのすぐれた耐側圧性

に低下させる結果を惹起する。 However, a disadvantage of this method of fixing the blocks to a flat belt is that the bolts must pass through the belt to secure the blocks, thereby cutting the tensile rope embedded in the belt. This has the effect that as the belt becomes thinner, the belt strength required for high-load transmission is significantly reduced.
本考案は、Ｖ形ブロツクベルトの上述の如き欠

るものである。 That is, the present invention makes it easy to attach the V-block to the belt in a V-block belt, and also stabilizes the support by regulating the movement of the belt in the width direction and length direction by the V-block. A V having a substantially trapezoidal or inverted trapezoidal cross-section, a concave groove on the upper surface for receiving and supporting the belt in its width direction, and a presser plate for pressing the upper surface of the belt. Using a V-shaped block, on the other hand, the upper surface or the lower surface of the flat belt, or both upper and lower surfaces, are provided with lateral unevenness of a constant pitch, and the V-shaped block is fitted by inserting the groove into the belt recess, and the upper surface of the block is It is characterized by a structure in which a large number of blocks are attached over the entire circumference in the longitudinal direction of the flat belt by being held by a presser plate and secured with bolts through the base portions at both ends of the block.

係止構造が施される。 Thus, the V-shaped block 2 is attached to the flat annular belt 1 by fitting its groove 10 into the groove 7 of the belt 1 described above. The presser plate 3 is engaged with the presser plate 11', and the flat annular belt 1 is held between the V-shaped block 2 and the presser plate 3. A locking structure is provided between the base portions 11, 11' and the presser plate 3.
この係止構造は最も一般的には押え板３と台部
１１，１１′とを通じ挿通したボルト１２による
係止である。 The most common locking structure is a bolt 12 inserted through the holding plate 3 and the base portions 11, 11'.

く起らない。 In this case, since the V-shaped block 2 is prevented from sliding in the longitudinal direction of the belt by the uneven parts 7 and 8 provided on the belt 1, there is no need to pass the block through the belt and fix it. Therefore, there is no fear of cutting the tensile cord within the elastic body of the belt.

うに設計することが効果的である。 Note that the concave portion 7 and the convex portion 8 of the belt allow power to be transmitted through the frictional resistance between the pulley and the block, and the concave portion 7 is the angle at which the block 2 and the above contact efficiently when the belt is bent by the pulley. On the other hand, it is effective to design the convex portion 8 to have a size and strength that can withstand the pressing force of the block without hindering the bending of the belt.

る。 As described above, the present invention forms an uneven portion on at least one side of the flat belt, and on the other hand, provides a groove on the upper surface of the V-shaped block, and attempts to attach the two by fitting these grooves into the groove. , the V-shaped block has pedestals at both ends of the groove, and the belt is held between the block and the holder plate by locking with bolts through the pedestals of the V-shaped block and the holding plate. Not only is it easy to attach the V-shaped block to the belt, but the block is fitted into a recess in the flat belt, and the belt is held within the recessed groove of the block to regulate movement in the width and length directions of the belt. This feature prevents slippage, stabilizes the support, and is extremely effective in transmitting high horsepower.Furthermore, when the V-shaped block and the flat belt are engaged, the bolts are attached to the holding plate and both ends of the block. Since the bolts are inserted through the base of the belt, there is no chance of them penetrating the belt, so there is no risk of cutting the belt's tensile strength, and this has the remarkable effect of maximizing the strength of the belt. have.
