Effect of lubricant extreme-pressure additives on rolling-element fatigue life by Richard J Parker( Book )

6 editions published in 1973 in English and held by 19 WorldCat member libraries worldwide

The effects of surface active additives on rolling-element fatigue life were investigated with the five-ball fatigue tester at conditions where classical subsurface initiated rolling-element fatigue is the sole mode of failure. Test balls of AISI 52100, AISI M-50, and AISI 1018 were run with an acid-treated white oil containing either 2.5 percent sulfurized terpene, 1 percent didodecyl phosphite, or 5 percent chlorinated wax. In general, it was found that the influence of surface active additives was detrimental to rolling-element fatigue life. The chlorinated-wax additive significantly reduced fatigue life by a factor of 7. The base oil with the 2.5 percent sulfurized-terpene additive can reduce fatigue life by as much as 50 percent. No statistical change in fatigue life occurred with the base oil having the 1 percent didodecyl-phosphite additive. The additives used with the base oil did not change the ranking of the bearing steels where rolling-element fatigue life was of subsurface origin
Apparatus for studying ball spinning friction by Steven T Miller( Book )

4 editions published in 1965 in English and held by 18 WorldCat member libraries worldwide

An experimental apparatus was designed and constructed at the NASA Lewis Research Center to study one aspect of spinning friction based on interfacial slip over the entire ball-race contact area. The apparatus is capable of measuring spinning moments of less than 0. Ol inch-pound at maximum Hertz contact stresses to over 400 000 psi, speeds to 3500 rpm, and under varying contact configurations and conditions. From the torque measurement, a coefficient of spinning friction can be calculated. The apparatus comprises a drive assembly, a dead-weight load assembly, a spherical upper test specimen, a cylindrically grooved lower test specimen of varying conformity, a lower test specimen housing assembly incorporating a hydrostatic air-bearing assembly, and a torque-measuring system. In operation, the upper test specimen is loaded against the lower test specimen through the drive shaft assembly by the dead- weight load assembly. As the drive assembly is rotated, the upper test specimen rotates against the stationary lower test specimen actuating the torque-measuring system. Preliminary tests were conducted under varying Hertz stress to 136 000-psi maximum Hertz stress at a spinning speed of 950 rpm, with a 51 percent ball-groove conformity using a polyphenyl ether (5P4E), a highly purified naphthenic mineral oil, and a di-2-ethylhexyl sebacate (MIL-7808). It was found that the coefficient of spinning friction decreased with increasing maximum Hertz stress to an intermediate stress level and had a minimum value of 0. 122, 0. 089, and 0. 050, respectively, for the lubricants listed previously

Elastohydrodynamic film thickness between rolling disks with a synthetic paraffinic oil to 589 K (600 ̊F) by Richard J Parker( Book )

3 editions published in 1971 in English and held by 4 WorldCat member libraries worldwide

Elastohydrodynamic (EHD) film thickness measurements were made in an X-ray rolling-disk machine with a synthetic paraffinic oil at temperatures from 339 to 589 K (150 [degree] to 600 [degree] F). The synthetic paraffinic oil both with and without an organic phosphonate antiwear additive is capable of providing an EHD film throughout the range of test conditions. The measured film thicknesses were less than predicted by EHD theory when the lubricant was used without the antiwear additive. The antiwear additive caused an increase in the measured EHD film thickness. The measured film thickness was more sensitive to contact stress than predicted by EHD theory. For the oil without the antiwear additive, variations of measured film thickness with speed and viscosity were similar to those predicted by EHD theory. The film thickness measurements verified results of 120-mm-and 25-mm-bore ball bearing tests with the same lubricant
