Theoretical and Experimental Analysis of Hydrodynamic Gas-Lubricated Journat Bearings. B. Sternlicht and R. C. Elwell. ASME, Transactions, v. 80, no. 4, May 1958, p. 865878. Presents a numerical solution for finite-width journal bearings and results of experiments conducted with air-lubricated hydrodynamic journal bearings. Comparison is made between theoretical and experimental results. Design formulas and recommendations for future studies also are included. Viscosity-Pressure Effect on Friction and Temperature in a JournaI Bearing. S. J. Needs. ASME, Trcknsactions, v. 80, no. 5, July 1958, p. ICJQQ-1103. Tests were undertaken to show differences in friction and operating temperature when heavily loaded partial journal bearings were operated with two different oils in the same viscosity range, but of widely different viscosity index and viscosity-pressure characteristics. A New Dry Bearing. R. E. Harmon. Mnchine Design, v. 30, July 24, 1958, p. 22-24. Known in Britain as DU, this new composite
of powdered lead, fluorocarbon pIastic, porous sphericaf bronze, and steel back-up strip has good qualities for bearing design problems. Influence of Load and Thermal Distortion on the Design of Large Thrust Beatings. R. A. Baudry, E. C. Kuhn, and W. W. Wise. ASME, Transactions, V. 80, no. 4, May 1958, p. 807-818. Describes some design considerations given to vertical water-wheel-generator thrust bearings in order to avoid highly concentrated loading during the starting period, and to obtain minimum distortion of the pad during operation at normal speed and load. The Effect of Heat Conductance on SliderBearing Characteristics. UT. H. Guilinger and E. A. Saibel. ASrwE, Tyansactiorzs, v. 80, no. 4. May 1958, p. 800806. The slider bearing without side leakage is considered when heat generated in the oil film may be conducted in the fluid as well as lost to the surroundings. Bearings for Aircraft Hydraulic Pumps. U’. S. Bobier, Jr. and C. R. Potter. Applied Hydraulics, V. II, May 1958, p. 108-110. Speed and pressure effects; type selection procedure.
5. WEAR AND WEAR RESISTANCE New Coefficients - Predict Wear of Metal Parts. Ernest Rabinowicz. Product Engineering, V. 29, no. 25, June 23, 1958, p. 71-73. New wear coefficients give answers that can lengthen life of a sliding system. With equations and other data are included examples of applications to design problems.
Fretting Corrosion of Cast Iron. F. T. Barwelland K. H. R. Wright. B.C. I. R. A. Journal of Research and Development, v. 7, no. 5, Apr. 1958, p. Igo+ 12 plates. Results show that lubricated cast iron specimens in the as-cast condition exhibit less susceptibility to fretting than the annealed specimens.
Selecting Bearing Metals That Will Not Seize. C. L. Goodzeit. Materials in Design Engineering, V. 47, June 1958, p. rag-log. Table gives information needed to select pairs of bearing metals that will not form strong welded junctions during operation.
Influence of Load on Liner Temperature and Wear in a High Speed Diesel Engine. 3f. R. K. Rao and K. N. Murthy. Indian Institute of Science, Journal, v. 40, sec. B, no. I, Jan. 1958, p. 1-10 + I plate. Tests showed that engines running on varying loads suffered more wear than engines running on full load.
The Mechanical Wear of Metals. W. Hirst. B&i& Journal of Applied Physics, V. 9. Apr. 1958, p. 125-132. Design of fundamental experiments for examining the wear phenomena encountered in the conditions of speed and loading of industrial machines. Apparatus in which nominal point or nominal line contact can be maintained indefinitely; phenomena observed when a lubrication is maintained up to very heavy loads; a method of measuring the thickness of the oil film in line contact conditions is outlined and some results given.
How to Protect Hydrocyclones Against Destruction by Corrosion and Erosion. (in Russian) V. S. Burlakov. Tsvetnye M&ally, V. 31, no. 5, May 1958, p, 14-20. Internal Pipe Coating. Paint, Oil & Ckmical Review, v. f 2I, Apr. 17, 1958, p. 18. Copon, an erosion-proof, friction-reducing industrial coating, is being used to protect the inside of a 7z-mile gas pipe line.
