摘要：

The results are shown of tests on the effect of an auxiliary external DC electric field on the braking torque of a rotating shaft. Experiments were carried out on a simplified model of an engine in whose interior a metal shaft rotated with given angular velocities. The shaft was lubricated with different oils producing an oil film between the shaft's surface and a lip seal. The influence of different oil temperatures on the braking torque was also examined. The results are presented here for fresh Polish oil LOTOS 15W40 and a lip seal diameter of 88 mm. An increase in the negative DC voltage applied between the shaft and stiffening ring of the lip seal caused a reduction in braking torque. (C) 2005 Elsevier B.V. All rights reserved.
