Seizure Resistance of Coatings in Four Ball Tests, Two Roller Tests and Gear Tests : Vibration, Control Engineering, Engineering for Industry

抄録

To clarify the seizure resistance and the frictional characteristics of rollers with various coatings, two roller tests on rollers coated with copper, graphite and molybdenum disulfide were carried out using an Amsler machine, and the flash temperature rise on the contacting surface when the rollers were seized was calculated. Further, the correlation between the test result of seizure resistance in the two roller machine and the previous test results in a power-circulating gear machine and in a Soda-type four ball machine was examined, and the frictional characteristics of the coatings wee estimated. From the experimental results, a correlation between the seizure resistance in the two roller tests and the scoring resistance in the gear tests was recognized. Also, the variation in the coefficient of friction in the two roller tests was different from that in the four ball tests.
