“…Most of this heat must be conducted into the ball and track, which implies a heat transfer rate of at least two orders of magnitude higher than that between combustion gases and turbine blades. A good elastohydrodynamic oil film, giving a friction coefficient m ¼ 0.03 [8], is assumed. In the event of oil film breakdown, there could be a five-to ten-fold increase in the friction and heat transfer.…”

The most frequently used ball bearing analysis and design computer programs are based on a quasi-static analysis of the ball dynamics which is fast and convenient, but involves assumptions that can be poor. The alternatives use a time-marching dynamic analysis that provides a better representation of the physics, but is too slow for use as a routine design tool. This article uses ideas that came from the experimental work to overcome a major assumption in the quasi-static analysis while allowing analysis of combined load bearings in real time on a standard PC.

“…Several investigators have worked on cage slip in roller bearings theoretically and experimentally. In previous studies, [2][3][4][5][6][7][8][9] the influence of different factors on cage slip has been examined. The factors included the radial load, shaft speed, the number of rollers, out-ofroundness, the presence of misalignment, viscosity and temperature of the oil, traction force, and so on.…”

“…O’Brien and Taylor 6 recorded the passing of cage rivets with a magnetic pick-up to obtain the cage speed. Ford and Foord 7 measured shaft and cage speeds optically by counting pulses from retro-reflective marks on the shaft and cage. Selvaraj and Marappan 8 used three proximity speed sensors to obtain the speed of inner race, cage, and roller.…”

Although the cage slip of cylindrical roller bearings has been measured and studied experimentally, it is difficult to use current experimental measurement to detect the cage slip of the bearing in actual service or engineering environment. The problem is attributed to the limit on the space for current test instruments that can be installed arbitrarily in laboratory, but not in actual environment. A novel measurement based on strain detection is presented. This measurement can be used to obtain the cage slip of the bearing in service or large bench test. The technique is demonstrated and validated in principle by an experimental system. The system is developed to obtain the strain signal of the outer ring in loaded zone as well as the speed signal of the cage and the inner ring at the same time. Under given test load–speed conditions, the cage slip based on strain detection was compared with the cage slip based on speed detection. Experimental results showed that cage slip ratio curves based on strain responses agreed very well with those based on speed signals. In this way, it is revealed that frequency characteristics of strain signals can be used to obtain internal cage slip of cylindrical roller bearings.

A technique for measuring roller speeds in cylindrical roller bearings using a modified laser anemometer has been developed. The technique described does not require any mechanical interference with the roller and cage geometries, and is suitable for high speed testing. The method has been used to measure roller speeds exceeding 15,000 rpm, in a standard 50 mm nominal bore, flanged inner track cylindrical roller bearing, under the conditions of light loads and lubricant starvation. Considerable cage and roller slip is detected only at radial loads less than 100 N, and the degree of slip present is found to be virtually independent of the low lubricant flow rates used in the investigation. / VOL 100, OCTOBER 1978Transactions of the ASME Copyright © 1978 by ASME Downloaded From: http://tribology.asmedigitalcollection.asme.org/ on 06/08/2015 Terms of Use: http://asme.org/terms Journal of Lubrication Technology OCTOBER 1978, VOL 100 / 487 Downloaded From: http://tribology.asmedigitalcollection.asme.org/ on 06/08/2015 Terms of Use: http://asme.org/terms
