Description

一种碳纤维复合材料的传动轴
技术领域
本发明涉及机械动力传输装置技术领域，尤其涉及一种碳纤维复合材料的传动轴。
背景技术
传动轴是由轴管、伸缩套和万向节组成，传动轴(DriveShaft)连接或装配各项配件，而又可移动或转动的圆形物体配件，一般均使用轻而抗扭性佳的合金钢管制成。由于常用的传动轴强度低和不耐腐蚀等特点，于是出现了碳纤维复合材料的传动轴，由于碳纤维复合材料具有高强度、高刚度、重量轻、耐腐蚀以及优异的电性能等，采用碳纤维复合材料传动轴可以满足传动***减震、降噪、减轻传动轴的重量，优化传动***的结构，提高传动***的性能，然而现有的传动轴还是较脆，且各向异性，采取机械连接容易导致连接部位的应力集中，降低了连接效率，同时在使用的过程中噪音较大，质量重，很容易由于长期的运动增加磨损量，降低了使用寿命和抗扭强度。
发明内容

所述轴体厚度为3mm。
所述内层是通过玻璃纤维增强树脂经喷射而成。
所述轴体两端的法兰圆周端面上固定孔至少两个，且均匀分布在法兰圆周端面上。
