Definitions
- the present invention relates to a transmission belt.
- transmission belts such as V-ribbed belts and V-belts are used as means for transmitting rotational power of engines and motors used in various mechanical devices and automobiles.
- the transmission belt is gradually worn by a load applied when the rotational power is transmitted, and breakage such as a crack occurs.
- a worn or damaged transmission belt cannot transmit power properly and may be cut off during operation of the apparatus. Therefore, it is necessary to replace the power transmission belt in which the wear has progressed by a certain amount or has cracked.
- Patent Document 1 proposes a technique for determining a wear state by providing a colored layer on the bottom surface of a V-belt and monitoring the remaining state of the colored layer. Further, Patent Document 2 proposes a technique for forming a conductive layer on a contact surface of a toothed belt with a pulley and measuring the electrical resistance to determine the wear state of the belt.
- Patent Document 1 is based on a V-belt, and monitors that the colored layer provided on the bottom surface of the V-belt comes into contact with the pulley and is peeled off as a result of wear of the side surface of the V-belt or the side surface of the V-pulley. . Therefore, it cannot be applied immediately to other types of belts.
- an object of the present invention is to realize a transmission belt that is simpler and has a wider range of use and that can detect wear even during use.
- the transmission belt of the present invention is a transmission belt that is wound around a pulley and transmits power, and includes a bottom rubber layer disposed on the pulley contact side, and at least a surface on the pulley contact side.
- the bottom rubber layer contains a luminescent agent.
- deterioration can be detected by monitoring the light emission of the luminescent agent. That is, if the bottom rubber layer is covered with the reinforcing cloth, the light emitting agent of the bottom rubber layer does not emit light, or even if it emits light, it is not detected because it is covered with the reinforcing cloth. On the other hand, when the reinforcing cloth is worn and cracks are generated, for example, the luminescent agent in the bottom rubber layer emits light or light emission is detected. Therefore, by monitoring the presence / absence and intensity of light emission, the state of the transmission belt, such as wear of the reinforcing cloth, can be confirmed.
- any belt such as a V-belt, a flat belt, a V-ribbed belt, or a toothed belt can be used as long as it is a transmission belt using a reinforcing cloth.
- the luminescent agent may emit light upon irradiation with ultraviolet rays.
- luminescent agents there are various types. For example, those that emit light when irradiated with ultraviolet rays can be used. In this case, in order to confirm the state of the transmission belt, it is only necessary to examine the presence or absence of light emission and the intensity by irradiating with ultraviolet rays (for example, the intensity of light emission at the time when the transmission belt needs to be replaced is examined in advance. If the intensity of light emission is confirmed, replace the belt).
- the luminescent agent may emit light upon contact with oxygen.
- the bottom rubber layer emits light even when the transmission belt is not used.
- this light emission is hidden by the reinforcing cloth covering the bottom rubber layer, and the apparent light emission is weakened.
- the light emission in the bottom rubber layer becomes easy to see. Therefore, it is possible to detect wear, cracks, and the like of the reinforcing cloth by monitoring the presence or absence of light emission and intensity.
- the reinforcing cloth may cover the entire transmission belt.
