SF-1B青铜基无给油轴承

SF-1B 铜基无给油轴承 | 材料组织 MATERIAL STRUCTURE | |  | 1. 改性聚四氟乙烯(PTFE)以及铅(Pb)的混合物 0.01-0.03mm,一种耐磨材料,运作过程中可形成转移膜,以保护对磨轴。 2. 铜粉层,0.20-0.3mm,提高PTFE/Pb与铜板层的结合强度,具有很好的承载能力和耐磨性。较高的导热系数可迅速转移运作过程产生的热量。 3. 铜基板0.7~2.3,提高轴承的承载能力和热传递,且有更好的耐腐蚀能力。 | 主要参数 TECHNICAL DATE | | 静承载 | 250N/mm2 | | 摩擦系数 | 0.03~0.20 | 最大承载 | 低速运转 | 140N/mm2 | | 最大线速度 | 干摩擦 | 2m/s | | 旋转、摇摆运动 | 60N/mm2 | | | 流体润滑 | 5m/s | 最大PV值 (干摩擦) | 间断性运作 | 3.6N/mm2.m/s | | 导热系数 | 70W(m.K)-1 | | 长期运作 | 1.8N/mm2.m/s | | 线膨胀系数 | 17x11-6K | 使用温度 | -195℃~+300℃ | | | | | 应用特点 APPLICATION CHARACTER | 除了与SF-1相同的优点外,还具有以下特性: 由于铜本身具有其自润性能,所以可用于需长时间工作而无法停机维修的部位,具有比SF-1更好的抗腐蚀性能。广泛运用于弱酸强碱场合、港口机械、船舶机械、冶金钢铁工业,连铸机方坯滚道、高温炉钢环部位、水泥灌浆泵和螺旋式输送机上。它可以在外部组合钢套,或制成翻边,端面、内孔同时摩擦使用。 |  | | |
