滑动轴承轴瓦通常多以磷青铜为材料,耐磨性较差,轴承间隙难以保证相对稳定,因间歇加润滑油,在负载运转过程中产生大量碎铜屑,使轴颈与轴瓦实际处于边界润滑状态,清洁卫生也差,存在着一些明显的缺点,我们经多年研究试验将聚四氟乙烯(PTPE)用到滑动轴承上,效果较好。这种材料具有如下优良性能: (1)耐高、低温,可在-195～+250℃范围
Most of the plain bearings are made of phosphor bronze, which has poor abrasion resistance. It is difficult to ensure the bearing clearance is relatively stable. Due to intermittent lubrication, a large amount of scrap copper is generated during the operation of the load, so that the journal and the bearing bush are actually lubricated at the boundary State, poor sanitation, there are some obvious shortcomings, we after years of research and testing will PTFE (PTPE) used in sliding bearings, the better. This material has the following excellent performance: (1) high temperature, low temperature, in the range of -195 ~ +250 ℃
