Rotating shaft lip-shaped sealing ring with elastic element and preparation method of rotating shaft lip-shaped sealing ring

The invention discloses a rotating shaft lip-shaped sealing ring with an elastic element and a preparation method of the rotating shaft lip-shaped sealing ring, and the preparation method comprises the following steps: step 1, carrying out pre-vulcanization treatment on the excircle of the elastic element through a rubber material which is the same as the rotating shaft lip-shaped sealing ring in material so as to obtain an elastic element prefabricated part with a stable shape; and 2, the elastic element prefabricated part is placed in a machining mold of the rotating shaft lip-shaped sealing ring to be integrally formed, and a finished product is obtained. According to the rotating shaft lip-shaped sealing ring with the elastic element and the preparation method of the rotating shaft lip-shaped sealing ring, the elastic element is pre-vulcanized, so that the spring is stabilized by pre-vulcanized rubber, the problem of large deformation of the spring is reduced, the relative stability of the shape of the sp
