きなかつた。(Problems to be Solved by the Invention) Generally, a power transmission belt transmits load torque by generating frictional force by its side pressure. However, the above-mentioned conventional rubber V that can be used for both forward and reverse bending
When the belt was subjected to high side pressure, the rubber V-belt buckled and deformed, causing heat generation and breakage. Current standard rubber V-belts are usually used with a belt side pressure of 4 to 5 kg/ cm2 or less, and even for high-load rubber V-belts, the limit is about 10 kg/ cm2 , and higher lateral pressure is not required. Torque voltage was not possible. In addition, in recent years, as a one-sided bent block type V-belt capable of high-load transmission, as shown in JP-A-60-49151, JP-A-61-21446, and JP-A-61-21447. Several methods have been devised, but none of them can be used for multi-axis transmission using a large number of pulleys e as shown in FIG. 7 because reverse bending is not possible.

残るものであつた。 Moreover, in particular, in the one disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-21446, an integral elastic block is sandwiched between each block by a tension band, so that the gap between each block is eliminated. When the belt wraps around the pulley, the elastic block is compressed and deformed, and a reaction force against this compression is generated in the elastic block. And this reaction force is
This works to return the belt that is curved around the pulley to a straight state, and there is a possibility that the belt cannot be stably wound around the pulley. Further, the tension body requires a material with high elasticity, and the applicable materials are limited. Therefore, problems remained in terms of practicality.

用できる。 A first embodiment will be described based on FIGS. 1 and 2. As shown in the figure, belt 1 in the present invention
is composed of a pair of tension bands 2, 2 and a plurality of blocks 3 arranged in the tension bands 2 in the longitudinal direction thereof. Block 3 is made of phenolic plastic with a high coefficient of friction and is heat resistant.
Made of material with excellent wear resistance. The upper and lower side surfaces 3a and 3b of the block 3 are respectively inclined surfaces having different inclination directions, and the inclined surfaces 3a and 3b form a belt angle α that matches the groove angle of the pulley. The opposing faces 3c and 3d of the blocks that face each other in the longitudinal direction of the tension band 2 are also inclined, forming an opposing face angle β, so that the belt 1 can be bent in both forward and reverse directions. In addition, side surfaces 3a and 3b are provided on the sides of each block 3.
Tension band engaging grooves 4 that are open to each other are formed, and a convex portion is provided on the upper and lower surfaces of each groove. The tension band 2 is composed of a woven fabric 7 having non-extensible core wires 5 arranged in the same plane and a rubber member 6 in which the core wires 5 are embedded, stretched on the upper and lower surfaces thereof. One side 2a of tension band 2
has the same slope as the side surfaces 3a and 3b of the block 3. Furthermore, the upper and lower surfaces of the tension band 2 are provided with recesses that engage with convex portions provided in the tension band engagement groove 4 of the block 3. The convex portion of the block 3 and the concave portion of the tension band 2 are the means for engaging the block 3 and the tension band 2, and conversely, there are cases where the block side is the concave portion and the tension band side is the convex portion for engagement. Non-stretchable core wire 5 embedded in tension band 2
Polyamide-based synthetic fibers are used, but other synthetic fibers such as polyester and polyaramid, inorganic fibers such as steel, glass, and carbon, or twisted cords, fabrics, and sheet-like cores made of blends of these fibers are also used. Lines may also be used. On the other hand, the rubber member 6 is made of a material having a large compressive Young's modulus and excellent wear resistance, and is made of synthetic rubber reinforced by mixing short fibers. Although cotton yarn is used for the woven fabric 7, synthetic fibers such as polyamide, polyester, and polyaramid, which have excellent flexibility and abrasion resistance, or blended yarns thereof may also be used. Note that the woven fabric may be omitted if the load is relatively light. Also, a synthetic resin sheet can be used instead of woven fabric.

ム等を使用してもよい。 The two tension bands 2, 2 and the block 3 are fixed in the length direction of the belt 1, and are normally removable in the width direction. When the belt 1 is fitted with the pulley and receives side pressure, the side surface 3a of the block 3,
3b, the side surfaces 2a of the tension band 2 are on the same surface, so the friction transmission force with the pulley is generated on all the side surfaces. Therefore, the belt 1 can withstand high lateral pressure and the transmission torque becomes large. In addition to the above-mentioned phenolic plastic, epoxy plastic, hard rubber, etc. may be used as the material for the block 3.

る。 Next, a second embodiment will be described with reference to Fig. 3. The differences from the first embodiment will be mainly described. The heavy duty power transmission belt shown in Fig. 3 has a side inclination angle at the upper part of the block 3 that is smaller than that at the lower part. With this configuration, the upper belt side 3a can generate a large side pressure by being fitted onto a pulley with a small inclination angle, so that the friction transmission force can be increased, and therefore it becomes possible to transmit a larger torque. On the other hand,
The lower belt side surface 3b, which is fitted to a pulley with a large inclination angle, cannot generate a large side pressure, and is therefore used when transmitting a relatively light torque or when it is fitted to an idler pulley or a maintenance pulley.

とが可能となる。 Next, a third embodiment will be explained with reference to FIG. In the high-load power transmission belt shown in FIG. 4, the folding tangent line 3e of the upper and lower side surfaces 3a and 3b of the block 3 (the ridge line at the connection position of the upper and lower side surfaces) is deviated upward from the plane containing the core wires. It is. With this configuration, the lower belt side surface 3b has a larger fitting area with the V-groove surface of the pulley, making it possible to increase the frictional transmission force and, therefore, to transmit a larger torque.
