Inventors: Pan Wenbin, M Lizhu, Huang Youjian et al. The present invention introduces a toothed rubber joint and a manufacturing method thereof . Engaged rubber joints include the mandrel, elastic rubber body and metal jacket, the three are integrally vulcanized together. The mandrel wall is provided with an upper protrusion and a lower protrusion which are distributed along a circumference of the mandrel and have the same shape and size. The upper bulge and the lower bulge are symmetrical up and down along the central axis of the mandrel, and are uniformly distributed along the axial direction of the mandrel. The width of the upper protrusion radially distributed along the mandrel is not greater than the diameter of the central portion of the mandrel. The inner wall of the metal jacket has the same width as the upper protrusion
