Description

一种低摩擦系数的轴承材料
技术领域
本发明属于机械材料技术领域，涉及一种轴承材料，特别是涉及一种低摩擦系数的轴承材料。
背景技术
轴承是在机械传动过程中起固定和减小载荷摩擦系数的部件。也可以说，当其它机件在轴上彼此产生相对运动时，用来降低动力传递过程中的摩擦系数和保持轴中心位置固定的机件。轴承是当代机械设备中一种举足轻重的零部件。它的主要功能是支撑机械旋转体，用以降低设备在传动过程中的机械载荷摩擦系数。按运动元件摩擦性质的不同，轴承可分为滚动轴承和滑动轴承两类。
船用轴承主要有水润滑和油润滑两种方式，其中水润滑轴承与油润滑轴承相比具有无污染、耗能小、摩擦系数低、价格低廉等优势，因此在船上得到了广泛地应用。水润滑轴承由轴承外套和轴承面层组成，轴承外套多采用耐腐蚀的黄铜制备，轴承面层多采用高分子材料制备。其中橡胶和聚氨酯由于性能优异应用较为广泛，然而在实际使用过程发现，在缺水等干摩擦工况下，材料摩擦性能极具恶化，极易出现抱轴和轴承烧焦现象。因此，应用轴承的材料需要具有自润滑性能，以适应干摩擦工况。
发明内容
本发明针对本发明为了解决传统轴承材料制备的轴承摩擦系数较大，高速运转后容易引起升温，导致润滑脂融化，进一步减少耐磨性能，影响轴承的使用寿命等不足，提供一种低摩擦系数的轴承材料，通过改变轴承材料的组份，可使轴承获得较高的耐磨性，能满足高要求场合的使用。

所述低摩擦系数的轴承材料由如下重量百分比的原理组成：超高分子量聚乙烯15～30%、碳纤维10～15%、丁腈橡胶10～15%、增塑剂1～1.5%、自润滑剂5～8%、氧化锌0.5～3.5%、硬脂酸0.1～0.8%、交联剂0.1～2.5%、抗氧剂0.2～2.5%、改性树脂5～8%、邻苯二甲酸二仲辛酯0.5～1%、发泡剂1～1.2%、阻燃剂0.2～0.8%。
所述低摩擦系数的轴承材料由如下重量百分比的原理组成：超高分子量聚乙烯15%、碳纤维10%、丁腈橡胶10%、增塑剂1.5%、自润滑剂8%、氧化锌0.5%、硬脂酸0.1%、交联剂0.1%、抗氧剂0.2%、改性树脂5%、邻苯二甲酸二仲辛酯0.5%、发泡剂1%、阻燃剂0.2%。
所述发泡剂为AC发泡剂。
邻苯二甲酸二仲辛酯为增塑剂。
丁腈橡胶为普通丁腈橡胶、氢化丁腈橡胶或羧基丁腈橡胶。
