摘要
介绍了摩擦滑移支座中聚四氟乙烯(PTFE)与不锈钢板之间摩擦系数的主要影响因素。指出正压力、滑移速度、环境温度以及润滑剂的使用都对PTFE-不锈钢接触面的摩擦系数有明显影响。并通过现场试验,得出摩擦滑移橡胶支座接触面之间的摩擦系数,根据试验结果回归给出了动摩擦系数的计算公式,并初步验证了摩擦系数与正压力以及润滑剂使用之间的关系。
The main factors that influent the friction coefficient of FPE interface between PTFE and stainless steel plate are introduced in this paper. And the conclusions that direct pressure, sliding velocity, air temperature and lubricant all played important roles to the friction coefficient of FPE are obtained. A field experiment is carried out, friction coefficient of sliding bearings is indicated, and according to the test data, formula of dynamical friction coefficient is regressed. Furthermore, relationship between direct pressure and use of lubricant are preliminarily validated.
