合理设计船舶尾管水润滑橡胶轴承的结构可以有效提高轴承摩擦学性能、承载能力，减小振动、延长服役时间。分析轴承长径比、摩擦面形状、水槽形式、橡胶层的厚度和硬度等结构要素对水润滑轴承的摩擦学性能及承载能力的影响，给出船舶尾管水润滑橡胶轴承结构设计中几个主要参数确定原则，为工程应用提供理论与技术支持。 Rational structure design of ship stern tube water-lubricated rubber bearing can effectively improve the tribological properties and carrying capacities, reduce vibration, and increase service time. The impact of some structural ele- ments, such as length and diameter ratio of bearings, stave shape, water groove form, facing layer thickness and hardness of stave, on the tribological performance and capacity of stem bearings was analyzed and concluded. The design principles of structural elements were proposed for the ship stern tube water-lubricated rubber bearing, which will provide theory and technical support for engineering applications.
