Description

聚四氟乙烯的新用途
本发明涉及非金属材料在机动车辆传动零部件上的应用。
以往的传动零部件均习惯于采用钢材或粉末冶金等材料制作。虽然具有高速运转所需要的强度，但是却不可避免地会产生很大的噪音，而且钢材和粉末冶金等材料的自润滑性能并不很理想，只能靠提高表面光洁度或浸油来提高润滑性能，因而使用寿命不够长。
本发明的目的在于寻求一种材料，既能满足机动车辆传动零部件所需要的强度，又可消除噪音，提高耐磨性能，增长使用寿命。
本发明通过对高强度、具自润滑性高分子材料进行筛选，并经大量的实验证明，采有下述材料替代现有的传动零部件的金属材料，可达到上述发明之目的。包括采用不用填料的各种氟塑料，或未填充的氟塑料，以及聚甲醛、尼龙等。它们的强度均可满足同步传送带导向滚轮轴承，张紧滚轮轴承所需求的强度，同时消除了由于传动零部件之间金属钢性接触所产生的噪音、以及经磨合后传动零部件之间的间隙变大而进一步产生的噪音、偏摆及径向跳动。典型适用的材料是聚四氟乙烯、聚甲醛。
实施例1，本发明选用填充15％玻璃纤维，5％石墨的聚四氟乙烯棒，经机械加工成147FM摩托车汽动机链条导向滚轮的轴套，该轴套与高碳钢的轴相配合，安装到147FM摩托车汽动机上，实际使用与使用铁基粉末冶金轴承作对比实验，通过大量的实验统计，结论如下：
Figure A9710740800041
实施例2，选用美国M90聚甲醛，重复实施例1的实验，所得结论与实施例1相仿。
