FZG is the Technical Institute for the Study of Gears and Drive Mechanisms (Forschungsstelle für Zahnräder und Getriebebau) of the Technical University in Munich, where this test rig was developed. The several scuffing load tests performed on the FZG test rig serve for determining the extent to which gear lubricants help
What are the Din 4768 and Din 50150?
DIN 4768:1990, Determination of values of surface roughness parameters Ra, Rz, Rmax using electrical contact (stylus) instruments; concepts and measuring conditions. DIN 50150:1976, Testing of steel and cast steel; Conversion table of Vickers hardness, Brinell hardness, Rockwell hardness and tensile strength.
What is the FZG standard scuffing load test?
In the FZG standard scuffing load test, a defined load is applied to a pair of spur wheels, which is increased after a certain run time. After each load stage, the gear wheels are inspected visually and wear is measured.
What are the different types of FZG test procedures?
FZG test procedures: 1? Part 1: FZG test method A/8,3/90 for relative scuffing load-carrying capacity of oils 2? Part 2: FZG test method A10/16,6R/90 for relative scuffing load-carrying capacity of lubricants with high EP… More
