A BASIC STUDY OF THE SLIDING CONTACTS IN ROLLING BEARINGS.

A new technique was developed for processing signals from the distance gage used in the measurement of skew and axial position of rollers in cylindrical roller bearings. The new method utilizes a small on-line computer to obtain average values of skew angles and axial positions of identified rollers as well as overall averages for all the rollers in the bearing. This method was used in processing previously tape recorded distance gage signals. Evaluation of the results showed two main causes for roller skew in the cylindrical roller bearing used in the tests misalignment between the rolling paths of the inner and outer ring and cage pocket misalignment. Other causes will be investigated in subsequent work. Instrumentation was set up for simultaneous recording of roller skew data on two distance gages for the purpose of determining the correlation between roller skew and axial motion. The feasibility of using on-line and digital computers in the processing of the signals is being studied.
