RUBBER ELEMENT FOR COMPRESSION-TYPE ELASTIC COUPLING

摘要

A rubber element according to the present invention includes a pair of mounting plates (2) attached respectively to a pair of rib surfaces of drive and driven ribs which are spaced and opposed to each other; and an elastic member (4) made of rubber held between the pair of mounting plates (2) which are spaced and opposed to each other and bonded to joining surfaces of the pair of mounting plates (2). The pair of mounting plates (2) are respectively provided with protrusions (3) protruding toward each other in central areas of the joining surfaces or lateral areas of the joining surfaces including the central areas and extending in a direction parallel to an axis about which flanges rotate.
