In order to make design processes of water lubricated thrust bearing in vertical shaft more scientific and normative and promote development of water lubricated thrust bearing with independent intellectual property rights,a design method of water lubricated thrust bearing based on multi-source knowledge was proposed in this paper. The core of the method utilized standards knowledge,experiential knowledge and experimental knowledge to realize knowledgedriven and combination-innovative design of bearing. The knowledge sources of design of water lubricated thrust bearing in vertical shaft were classified,and approaches of achieving design knowledge were discussed. A knowledge base of design of water lubricated thrust bearing was built to make design knowledge acquired and used. A design example about water lubricated thrust bearing of vertical shaft was implemented,obtaining the design flow chart of the bearing based on the method of multi-source knowledge. According to static performance simulation,the designed bearing met the requirement of usage. The design method in this paper improves the design efficiency of bearing.
