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

3 editions published in 1973 in English and held by 3 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

Elastohydrodynamic analysis using a power law pressure-viscosity relation by Stuart H Loewenthal( Book )

2 editions published in 1973 in English and held by 2 WorldCat member libraries worldwide

An isothermal elastohydrodynamic (EHD) inlet analysis of the Grubin type which considers a power law pressure-viscosity relation and a finite pressure at the inlet edge of the Hertzian contact zone was performed. Comparisons made with published X-ray EHD film thickness data for a synthetic paraffinic oil and when conventional EHD theory showed that the present theory exhibits a slightly stronger film thickness load dependence than do previous isothermal EHD theories but far less than that exhibited by the measured data
Effect of residual stresses induced by prestressing on rolling-element fatigue life by Richard J Parker( Book )

2 editions published in 1972 in English and held by 2 WorldCat member libraries worldwide

A mechanical prestress cycle suitable to induce compressive stress beneath the surface of the inner race of radially loaded 207-size bearings was determined. Compressive residual stress in excess 0.69 x 10 to the 9th power N/sq m (100,000 psi), as measured by X-ray diffraction, were induced at the depth of maximum shearing stress. The prestress cycle consisted of running the bearings for 25 hours at 2750 rpm at a radial load which produced a maximum Hertz stress of 3.3 x 10 to the 9th power N/sq m (480,000 psi) at the contact of the inner race and the heaviest loaded ball. Bearings subjected to this prestress cycle and subsequently fatigue tested gave a 10 percent fatigue life greater than twice that of a group of baseline bearings

Kinematic Precision of Gear Trains( Book )

1 edition published in 1982 in English and held by 1 WorldCat member library worldwide

Kinematic precision is affected by errors which are the result of either intentional adjustments or accidental defects in manufacturing and assembly of gear trains. This paper explains a general method for the determination of kinematic precision of gear trains. The general method is based on the exact kinematic relations for the contact point motions of the gear tooth surfaces under the influence of errors. An approximate method is also explained. Example applications of the general and approximate methods are demonstrated for gear trains consisting of involute (spur and helical) gears, circular-arc (Wildhaber-Novikov) gears, and spiral-bevel gears. Gear noise measurements from a helicopter transmission are presented and discussed with relation to the kinematic precision theory. (Author)

Effects of antiwear and extreme-pressure additives in a synthetic paraffinic lubricant on ball spinning torque by Dennis P Townsend( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

Tests were conducted in the NASA spinning-torque apparatus to determine the effect of lubricant additives on the torque of a ball spinning in a nonconforming groove. The base lubricant was a synthetic paraffinic oil to which were added 0.1, 1. 0, and 10 volume percent of either an antiwear or EP additive. The additives used were stearic acid, oleic acid, oleyl phosphate, oleyl phosphite, and zinc dithiophosphate. Under the test conditions, elastohydrodynamic lubrication prevailed with no significant surface interaction. The addition of the antiwear or EP additives in several concentrations to the synthetic paraffinic oil did not change the spinning torque over that obtained with the base fluid. The viscoelastic properties of the base fluid were not changed by the additives tested.--P. [i]
Friction losses in a lubricated thrust-loaded cageless angular-contract bearing( Book )

1 edition published in 1973 in English and held by 1 WorldCat member library worldwide

The NASA spinning torque apparatus was modified to measure the spinning torque on a cageless ball thrust bearing. Friction torque was measured for thrust loads varying from 44.5 to 403 newtons (10 to 90 lb) at speeds of 1000, 2000, and 3000 rpm. Tests were conducted with di-2-ethylhexyl sebacate and a synthetic paraffinic oil. These tests were run with either oil jet lubrication or with a thin surface film of lubricant only. An analytical model which included rolling resistance was developed and extended from previous models for spinning torque and lubricant rheology. The model was extended by the inclusion of rolling resistance. The computed values were in fair agreement with the experimental results and confirmed previous hypotheses that a thin lubricant film gives minimum bearing torque and an oil jet flow of a viscous lubricant will result in considerable rolling torque in addition to the torque due to ball spin
