Development of an experimental rig with hydrostatic bearings for testing the EHD traction force of high‐speed lubricants

Abstract A test rig for the EHD traction force of lubricants is essential equipment for the study of the non‐Newtonian properties of lubricants operating at high pressure. In this paper is described the development of test equipment with hydrostatic bearings, on the basis of analysis of EHD traction and other test rigs. Hydrostatic bearings allow the rig to pick up the signals of the EHD traction force more precisely. Thus, good test results for an aviation lubricant have been obtained.
