Standard Test Method for Determining Fretting Wear Resistance of Lubricating Greases Under High Hertzian Contact Pressures Using a High-Frequency, Linear-Oscillation (SRV) Test Machine

Importancia y uso:

5.1 This test method can be used to determine anti-wear properties and coefficient of friction of greases in order to prevent “fretting” wear under linear oscillation with associated low strokes and high Hertzian contact pressures at selected temperatures and loads specified for use in applications in which induced, high-speed vibrational motions are present for extended periods of time. It has found application as a screening test for grease lubricants used in ball and roller bearings, roller or ball screw (spindle) drives or side shaft systems (Tripode or Rzeppa type) for example, so-called constant velocity (CV) joints. Users of this test method should determine whether results correlate with field performance or other applications.
