EXPERIMENTAL PROOF OF THE ELASTOHYDRODYNAMIC EFFECT

A new experimental method of direct measurement of the hydrodynamic flow rate of lubricant through the working slot of a bearing and lateral leaks of lubricant from the slot is described, and results of application of this method are also listed. The ability of a sliding block of the new type to work in a wide range of load at very large hydrodynamic flow rates of lubricant and immaterial magnitude of its lateral leaks (near 2% from flow rate through the slot to 60 - 70% in rigid supports working on oils) was experimentally proven. Namely thanks to small lateral leak at significant hydrodynamic flow rates through the slot a layer of lubricant of significant thickness is formed, which ensures work of the bearing with very low friction in a wide range of operating conditions, and also its long period of service.
