在摩擦连接处，即在旋转的金属轴基油-旋转唇密封系统中，会发生机械和电气性质的动态现象。在轴的旋转过程中，在离心力的作用下，油膜的组成部分——轴的表面和旋转唇密封的唇之间的间隙——在油膜内移动。不同粒子和分子的相对运动反过来又带来摩擦充电，并导致在间隙内建立电场。作用于库仑力的电场和范德华引力一样，也会影响带电物质的分布。为了分析上述因素的影响以及油液温度的影响，在不同的基础油温度和不同的油液角速度范围内，对旋转金属轴与密封密封强化环之间的电压和制动扭矩进行了测量。在实验中，使用合成的PAG（聚烷基二醇）和PAO（聚α -烯烃）基础油和氟碳旋转唇密封。
In the friction junction, that is in a rotating metal shaft–base oil–rotary lip seal system, dynamic phenomena occur which are of mechanical and electrical nature. During the shaft׳s rotation the components of an oil film – a gap between the surfaces of a shaft and a lip of a rotary lip seal – are caused to move about within the film under the action of a centrifugal force. The relative movement of different particles and molecules in turn brings about tribocharging and results in establishing an electric field within the gap. The field and so acting theCoulombforce also affect the distribution of charged species as does thevan der Waalsattractive force. To analyze the effect of the above factors as well as the temperature of oil in the gap measurements of the shaft׳s braking torque and the voltage between the rotating metal shaft and a stiffening ring of a lip seal for different ranges of the base oil׳s temperatures and of the shaft׳s angular velocities are performed. In the experiments the synthetic PAG (polyalkylene glycol) and PAO (polyalphaolefin) base oils and a fluorocarbon rotary lip seal are used.
