- a belt is disposed and attached to the back of the belt.
- the back canvas is not subjected to a wide-angle treatment, and the same pelt resistant as that of the case where the back canvas is applied is provided. It has a tearing property.
- an auto-tensioner configured so that the tensioner pulley presses the back of the belt to keep the belt tension constant is used, as shown in Figs.8A and B.
- the belt D is biased in the belt width direction by the tensioner pulley 63, which is a flat pulley provided between the pair of rib pulleys 61, 62, so-called belt deviation may occur.
- the tensioner pulley 63 which is a flat pulley provided between the pair of rib pulleys 61, 62, so-called belt deviation may occur.
- the belt span length is shortened as described above, the alignment angle between the running direction of the belt and the direction perpendicular to the pulley axis becomes large due to the belt deviation, which causes abnormal noise. There is.
- the belt deviation is caused by the deviation of the alignment of the front and rear pulleys, the deviation of the alignment of the tensioner pulley, the pulley shape, the looseness of the pairing, the external factors of the belt, and the deviation of the belt inside the biased pelt. Clarified that the belt shift occurs due to the relevant factors and. The inventor has also clarified that, among the misalignments of the tensioner pulley, the misalignment of the tensioner pulley is caused by the inclination of the tensioner pulley due to running deterioration, and this is greatly involved in the belt misalignment.
- An object of the present invention is to provide a friction transmission belt capable of correcting a belt shift due to an external factor.
- the present invention provides a friction transmission belt having a bias in a belt width direction so as to offset a Pelt shift caused by an external factor.

- the short fiber-containing rubber is characterized in that it is integrally provided on the back of the belt such that the orientation direction of the short fibers is at an angle to the belt width direction.
- the belt has a directivity in which the belt tries to run in the direction of the short fiber orientation of the short fiber-containing rubber, and therefore, the belt is likely to be offset when the belt runs. Belt deviation due to external factors can be corrected by offsetting the belt deviation.
- the angle between the orientation direction of the short fibers of the rubber containing short fibers and the width direction of the belt is 10 ° or more and 45 ° or less.
- belt deviation can be effectively suppressed. That is, if this angle is smaller than 10 °, the effect of correcting the belt misalignment may be diminished, while if this angle is larger than 45 °, the bias of the belt itself becomes large and the correction is performed. The effect may be excessive. From this viewpoint, it is more preferable that the angle be in the range of 10 ° to 30 °, as will be described later in Examples.
- a single staple fiber-containing rubber is prepared and the direction in which the warp of the blind woven fabric extends or the orientation direction of the staple fiber of the unvulcanized rubber containing the staple fiber is set for each belt type. Since it is only necessary to change the material, there is no need to prepare individual materials as in the improvement of the core wire, and the cost increase can be suppressed accordingly.

- Example 2 longitudinal tear damage on the back of the belt was observed only in Example 2. This is because in Example 1, the direction in which the warp and weft yarns of the reinforcing cloth extend is at the same angle with respect to the belt width direction, whereas in Example 2, the bisector of the intersection angle of the warp and weft yarns is This is because the extending direction is set at an angle of 110 ° to the belt width direction, so that any of the yarns extends in the direction close to the belt width direction, and the belt longitudinal tear resistance is reduced. it is conceivable that. In Examples 3 to 7, in which the back of the belt was reinforced with rubber containing short fibers, no damage was observed. Therefore, it is considered that there is a sufficient reinforcing effect regardless of the arrangement. Industrial applicability
- the present invention is useful for a friction transmission belt.
