Foreword

GB/T 18325 "sliding bearings fatigue" consists of the following four components. --- Part 1. hydrodynamic lubrication conditions in the test machine and plain bearings fatigue practical application; --- Part 2. a cylindrical metal bearing material test specimens; --- Part 3. metallic multilayer bearing material flat belt test; --- Part 4. metallic multilayer bearing material pad test. This section GB/T Part of 418,325. This section identical with ISO 7905-4.1995 "Sliding Bearing fatigue - Part 4. metallic multilayer bearing material bush test". This section is equivalent translation ISO 7905-4.1995. For ease of use, this section made the following editorial changes. --- "This International Standard" be replaced by "this section"; "." --- With a decimal point instead of a comma as the decimal point, ""; --- Delete international standards foreword.

3 Sample

Samples should be ready to use the pad. Generally, since the test load conditions, the main stress is located at the top of the pad. Prior to testing and process Should try to avoid sample surface mechanical damage or corrosion. The advantage of this method is that the test sample is accompanied by the existence of the manufacturing process yield Students residual stress. Test Method 4 Test principle shown in Figure 1. Sample should be clamped at one end, the other end of the thinning at the interface eccentric method of applying force or displacement by radial And loaded. Work load should be pressed to the surface of the inner liner from Joan move. In addition, a previously applied tensile or compressive prestress, in order to evaluate The average stress correlation. Test equipment should be placed in the tank containing the lubricating oil, lubricating oil temperature fluctuation at ± 2 ℃; or ambient temperature Fluctuation test at ± 2 ℃ air.
