Abstract:Water-lubricated rubber bearings are widely used in power propulsion shafts of pumps, power plants, ships, and submarines because of their non-pollution, vibration absorption, and insensitivity to impact.However, due to their long-term work in harsh river and ocean environment, impurities in lubricating media lead to wear failure of water-lubricated rubber bearings, which affects their load-bearing characteristics.In order to analyze the load-bearing characteristics of water-lubricated rubber bearings after wear, a lubrication models of six-groove normal rubber bearings and three wear-type bearings were established by means of the Reynolds equation and deformation equation of rubber lining.The lubrication models were solved numerically by a finite difference method and an over-relaxation iteration method.Based on the numerical model, the load-bearing characteristics of normal and wear bearings were compared and analyzed.The results show that grooves have a great influence on the load-bearing characteristics of rubber bearings.Among the three kinds of wear rubber bearings, uniform wear has the greatest influence on the lubrication load-bearing characteristics, followed by conical wear and local wear.The results have reference value for the design of load-bearing characteristics and the construction of wear monitoring indexes of water-lubricated rubber bearings.
