Definitions
- the present invention relates to a transmission belt such as a V-ribbed belt or a V-belt, and more particularly to a technique for ensuring transmission capability during water injection and preventing abnormal noise.
- the compressed rubber layer is cut into several mm in the rib rubber of the rib portion in contact with the pulley.
- Known to be filled with embedded short fibers By filling the short fibers, the friction coefficient of the rib rubber against the pulley is lowered to prevent the generation of abnormal noise during the belt running and to suppress the wear of the rib rubber.
- Patent Document 1 not only a V-ribbed belt, but also a transmission belt including other types, water-soluble short fibers are added to the compression rubber layer of the rubber of the compression rubber layer. Filling 1-20 parts by mass with respect to 0 parts by mass, the water-soluble short fibers on the surface of the compressed rubber layer are dissolved and removed by the presence of water, and a recess is formed in the trace, so that water is injected. It has been proposed to contain water in a recess to destroy the water layer and suppress the generation of abnormal noise due to belt slip.
