Abstract:
      The rotating shaft lip rubber seal ring working under water was studied.Based on the finite element analysis method，the effects of installation interference and medium pressure on the sealing performance of the lip rubber seal ring were investigated.A three-dimensional axisymmetric finite element model of the lip ring seal was set up using ANSYS software.Simulation analysis showed that，the contact width and maximum contact pressure at the lip increased with the increase of the installation interference，and the spring-loaded lip seal ring had a larger contact width and a greater contact pressure than the lip seal ring without spring.With the increase of the medium pressure，the maximum contact pressure at the lip increased.The maximum contact pressure occurred at the tip of the lip and it was always greater than the medium pressure.
