<p>Multiple helical teeth (1, 2, 7, 8) are disposed on an outer diameter, an inner diameter, or a contacted surface of the outer diameter and the inner diameter of an interference designed shaft rubber seal provided with fixing rings and an arrangement of helical teeth, and a contacted surface of the outer diameter uses a cornice-type interference design. An inner side surface, an outer side surface, or the two side surfaces of the shaft rubber seal can be provided with fixing rings (4, 5). The fixing rings and a main sealing ring of the shaft rubber seal can relatively move, so that the main sealing ring of the shaft rubber seal has an extra function of floating up and down. The helical teeth can incline towards a side of a sealing fluid or incline away from the side of the sealing fluid or incline towards both the two directions at the same time, so that the shaft rubber seal has floating elasticity, and the effects of static sealing and the floating effects are improved.</p> |
