National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Research on Elastohydrodynamic Lubrication of High Speed Rolling-Sliding Contacts.

AD750752

Publication Date	1972
Personal Author	Smith, R. L.; Walowit, J. A.; Gupta, P. K.; McGrew, J. M.
Page Count	157
Abstract	A rolling disc apparatus was used to obtain traction measurements for a MIL-L-7808 oil. A full matrix of data covering a range of loads, speeds, and temperatures are presented along with analytical correlation which reasonably describes the data over these parameters. Attempts were made to measure film thickness with optical, capacitance, and X-ray measuring techniques. The partial elastohydrodynamic regime was studied analytically and experimentally. Electrical continuity and resistance data have been obtained and comparisons between measured electrical resistance and predictions obtained with the asperity interactions analysis put forth in Task 2 were obtained.
