The Influence of Base Oil Properties on the Friction .

Better understanding of the effect of base oil viscosity on friction can only be achieved if greases made of the same base oil type are compared [].PAO was chosen as the most suitable oil type for this investigation, due to its definite and consistent composition [], with consequent improvements in repeatability of the results and validity of the described comparisons.

Preparation of soybean oil-based greases: Effect of composition and structure on physical properti

Vegetable oils have significant potential as a base fluid and a substitute for mineral oil in grease formulation. Preparation of soybean oil-based lithium greases using a variety of fatty acids in the soap structure is discussed in this paper. Soy greases with lithium−fatty acid soap having C12−C18 chain lengths and different metal to fatty acid ratios were synthesized.

Grease Basics - Efficient Pla

Composition As previously illustrated, grease consists of three components: thickener, base oil and additives. Thickener… The thickener defines the type of grease (see Fig. 2). Greases are classified into two major families: soap and non-soap thickeners. More than 90% of the thickeners used worldwide are soap based.

Fatty acids and antioxidant effects on grease microstructur

Fatty acids and antioxidant effects on grease microstructures ... other greases made with varying composition of base oil, fatty acid, lithium hydroxide, and additive. ... dispersions owing their consistency to a gel-type network. A typical composition of grease includes base fluids, thickener, and additives ( Fig. 1). The

Grease Consistency and Thickener Type. Now for that extra step: The consistency of grease is controlled by the thickener concentration, thickener type and the viscosity of the base oil. Even though base oil viscosity affects consistency, it is important to note that a grease can have a high consistency and a low base oil viscosity or vice versa.

chemical composition of the grease. Fourier transform infrared (FTIR) spectroscopy identifies the type of base oil and thickener of the used grease [7]. FTIR was used to evaluate the chemical composition of standard grease and the synthesized sample produced in the laboratory. Figs. (5) and (6) represent the spectra for fresh

For a specific oil type, the influence of base oil viscosity on friction was found to be closely related to its effect on film thickness: greases formulated with PAO oils covering a wide range of ...

The influence of bearing grease composition on friction in .

far more complex rheological system than a simple base oil, so it is difficult to ascribe lubricant film formation and thus bearing fric-tional behaviour to a single grease component. The composition and properties of the lubricating film are likely to depend on both the grease properties (base oil and thickener type, additives,

INFLUENCE OF GROUP II & III BASE OIL COMPOSITION ON VI AND .

lubricating base oil. The more resistant a base oil is to oxidation, the less tendency it has to form deposits, sludge, and corrosive byproducts in grease, engine oil and industrial oil applications, and the more resistant it is to undesirable viscosity increases during use. Studies have shown that base oil composition can have a significant

The Effect of Selected Grease Components on the Wear Behavior of Grease-Lubricated Gea

The investigations showed that the base oil type and viscosity only have a slight effect on gear wear behavior under boundary lubrication conditions. However, the thickener type and especially the additive type as well as the solid lubricant type significantly affect the wear behavior of gears running at slow speeds and lubricated with grease.

The influence of bearing grease composition on friction in .

The composition and properties of the lubricating film are likely to depend on both the grease properties (base oil and thickener type, additives, rheology) and operating conditions (speed, temperature and bearing design). There are a number of models for grease lubrication of bearings.

Grease (lubricant) - Wikiped

Grease is a semisolid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil.[1] The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil ...
