Tīmeklis1994. gada 1. sept. · The study shows that the Lambda ratio is not the only parameter which affects the surface fatigue of bearings. In most cases, the life ratio depends … TīmeklisEach regime is defined by the ratio of the film thickness to the surface roughness, or the λ ratio (Figure 1). Such curves are often used to evaluate the effect of changes to the lubricant’s viscosity or to the lubricant’s additive package, or the effect of …

A Reassessment of Lambda Ratio as a Bearing Surface Fatigue …

Tīmeklis2024. gada 6. jūn. · Lambda ratio is a very well known parameter in the field of lubrication and tribology that is used to distinguish the lubrication regimes. (2) Here is … Tīmeklis2024. gada 18. jūl. · Fig. 4 shows the test results plotted on a graph with lambda ratio as the abscissa and maximum Hertzian pressure as the ordinate. Micropitting occurs above lambda = 0.1, except for one outlier that had a primary failure mode of abrasive wear, while abrasive wear and pitting occur below lambda = 0.1. TīmeklisGrease for bearings are typically NLGI 1, 2 or 3. The test measures how deep a cone falls into a grease sample in tenths of mm. Temperature range Comprehends the suitable working range of the grease. It goes between the low temperature limit (LTL) and the high temperature performance limit (HTPL). how much mold is dangerous to eat
