以丁腈橡胶（NBR）为基体，制备水滑润橡胶轴承,以水作为润滑介质，研究不同因素对橡胶轴承的硬度和摩擦磨损性能的影响.结果表明，随着炭黑量以及二硫化钼量增加，橡胶轴承的硬度逐渐增大；炭黑量和二硫化钼量明显影响橡胶轴承的磨损量和摩擦系数.在炭黑为70 phr，二硫化钼为10 phr时，轴承的磨损量和摩擦系数最小.对磨损和摩擦机理也进行了分析.
Abstract
The water lubrication rubber bearing was made by using NBR as matrix, and water as a lubricating medium. The effects of different factors on rubber bearings hardness and friction and wear properties were studied. Results show that as the amount of carbon black and molybdenum disulfide gradually increasesing as well, the hardness of the rubber bearing is increasing. The amount of carbon black and molybdenum disulfide significantly affect the wear loss and coefficient of friction of the rubber bearing, when the carbon black is 70 phr, and molybdenum disulfide is 10 phr, the rubber berings have the smallest wear loss and friction coefficient. The friction and wear mechanism are also analyzed.
