配設した高負荷伝動用ベルトが使用されている。(Prior art) Conventionally, a V-belt with a V-shaped cross section was generally used as this type of power transmission belt, but due to its poor wear resistance, recently V-belts made of friction-resistant materials have been recently used. A high-load power transmission belt is used in which a large number of shaped blocks are arranged along the length of a flat belt or a neutral belt having irregularities.
しかし、この高負荷伝動ベルトは構造上、Ｖ形
ブロツクをボルト等を用いてベルトに止着するも

そのため更に種々の改良提案がなされ、ブロツク
材質、ベルトとブロツクとの嵌合態様などについ
て改善が試みられている。 However, due to the structure of this high-load power transmission belt, V-shaped blocks are fixed to the belt using bolts, etc., and there are problems with installation, including friction between the bolts and the belt, as well as fatigue and wear of the rubber. There is,
Therefore, various proposals for improvement have been made, and attempts have been made to improve the material of the block, the manner in which the belt and the block fit together, etc.

る。 In particular, when improving belts for high-load power transmission as described above, one of the issues that should be kept in mind is wear resistance and heat dissipation of frictional heat generated when the belt engages with a pulley. Cooling air is introduced into the V-belt and V-pulley from inside and outside the belt transmission device to cool the V-belt and prevent deterioration of the V-belt. JP-A-61-103032 proposes that a rib be provided on the outer surface of one of the belts to provide the belt itself with a cooling function.

固定せしめた点にある。(Means for Solving the Problems) That is, the feature of the present invention is that in the V-belt with blocks in which blocks are arranged on the belt, the upper and lower extending portions are connected by a central connecting portion. , a horizontal H with a belt insertion part provided between the upper and lower extending parts.
A large number of shaped metal blocks are inserted into the insertion portions of the endless belt at required pitches along the longitudinal direction of the endless belt, which has cog grooves at a constant pitch on at least one side of the top and bottom, and these blocks are inserted into the cog grooves on at least one side of the belt. In addition, the upper and lower extending portions are hollowed from both ends, and a lid member having a protrusion that fits into each hollow end is provided, and the protrusion is fitted into the upper and lower extending portions. Fitted into the hollow end,
It is at a fixed point.

とが肝要である。 The lid member is usually made of polyurethane, other resins, or rubber, or a reinforcing material in which various short fibers and canvas are embedded either singly or in combination, and the shape is vertical. As long as the end of the extension part has a protrusion that can be inserted, there is no particular problem, but since it is a contact part with the V-pulley, the angle formed by the line connecting the left and right upper and lower end surfaces is
It is important that the angle is suitable for this, such as between 18 and 45 degrees.

This is a high-load power transmission belt in which blocks are fitted into the cog grooves, and cover members made of the required material are fitted into the left and right ends of the vertically extending portions, and the blocks and the endless belt are fitted with the cog grooves. Because of this, it not only has good stability and can even out the stress applied to the teeth to fully demonstrate its transmission ability, but also
It is easy to assemble because no bolts are used for assembly, and has the remarkable effect of significantly increasing high-load transmission efficiency.
