False brinelling
| Oil glossary |
- False brinelling of needle roller bearings is actually a fretting corrosion of the surface since the rollers are the i.d. of the bearing. although its appearance is similar to that of brinelling, false brinelling is characterized by attrition of the steel, and the load on the bearing is less than that required to produce the resulting impression. it is the result of a combination of mechanical and chemical action that is not completely understood, and occurs when a small relative motion or vibration is accompanied by some loading, in the presence of oxygen.
- A form of fretting corrosion, caused by vibration, that occurs in rolling element bearings while sitting idle and subject to friction oxidation.
- Fretting wear indentations. compare brinelling.
- See wear, fretting.

Brinell, английский
Brinell hardness, английский
- A system to measure the hardness of metals by indentation. a hardened steel ball is pressed into a smooth surface of the metal under a fixed load and the resulting indentation is microscopically measured. with a conversion chart, this number can also be used to determine the approximate tensile strength of the same metal.
- A measure of the hardness of a metal, as determined by pressing a hard steel ball into the smooth surface under standard conditions. for aluminum, the steel ball is 10 millimeters in diameter and total load is 500 kilograms. results are calculated as the ratio of applied load to total surface area of indentation and are referred to in terms of brinell hardness number or bhn.
Brinell hardness number, английский
Число твердости по бринеллю внр brake horsepower полезная мощность (воздушного винта); тормозная [эффективная] мощность (двигателя) внрс brake horsepower corrected приведенный к эффективной мощности
Brinell hardness test, английский
Brinell hardness tester, английский
Brinell hardness testing, английский
- Evaluation method for determining the hardness of a material by forcing a hard steel or carbide ball of specified diameter (often 10 mm) into it under a specified load. the diameter of the indent is measured, and the result is reported as the material’s brinell hardness number. compare rockwell hardness testing.
- Evaluation technique for determining the hardness of a material by forcing a tungsten carbide ball of specified diameter (often 10 mm) into it under a specified load. the diameter of the indent is measured and the result is reported as the material’s brinell hardness number with tungsten carbide (hbw; as “w” is the chemical symbol for tungsten). previously a hardened steel ball indenter was used. compare rockwell hardness testing.
Brinelling, английский
- Permanent deformation of the bearing surfaces where the rollers (or balls) contact the races. brinelling results from excessive load or impact on stationary bearings. it is a form of mechanical damage in which metal is displaced or upset without attrition.
- Repeated stripe indentations made by a spherical object. false brinelling refers to a type of surface wear.
- Permanent surface deformation caused by contact stress above the material’s limit. compare false brinelling.
- Permanent surface deformation caused by contact stress above the material’s limit. compare wear, fretting.
