Topic: Grease (lubricant)


  
  Grease (lubricant) - Wikipedia, the free encyclopedia
Grease is a lubricant of higher initial viscosity than oil, consisting originally of a calcium, sodium or lithium soap jelly emulsified with mineral oil.
Greases are a type of shear-thinning or pseudo-plastic fluid, which means that the viscosity of the fluid is reduced under shear.
Greases are employed where heavy pressures exist, where oil drip from the bearings is undesirable, and/or where the motions of the contacting surfaces are discontinuous so that it is difficult to maintain a separating lubricant film in the bearing.

 Precision Engineering - Lubrication
Grease is an oil to which a thickener has been added to prevent migration from the lubrication site, resulting in longer life.
Grease packing approximately 1/4 to 1/3 of a ball bearing’s internal free volume is one of the most common methods of lubrication.
Grease plating consists of mixing a quantity of grease and solvent to the desired consistency, lubricating the bearing with this mixture, then evaporating the solvent at a moderate temperature, leaving a thin film of grease on raceways and balls.

 Characterisation of Grease Lubricant Films
Grease is a two-phase lubricant composed of a thickener dispersed in a base fluid, however, the composition of the film will not necessarily reflect that of the bulk lubricant.
In bearings grease experiences a wide range of conditions depending on operating conditions (temperature, speed, load) and the local distribution of the grease.
Her current research interests include grease lubrication mechanisms in rolling element bearings, elastro hydrodynamic lubrication and the application of spectrophotometric techniques to lubrication research.

 Yarn twister ring lubricant - Patent 4242861
A twister ring lubricant is formulated using a major portion of paraffin wax and a minor portion of conventional oil or grease.
Due to the fact that the lubricant lasts for about 40 to 50 hours, only about 1/5th to 1/10th of the consumption of the paraffin base lubricant is required as compared to the prior art lubricant.
The lubricant was used on a number of individual twisters in order to compare the electrical requirements as compared to the prior art grease.

 Increased Lubricant Maintenance Intervals
In addition, grease sometimes becomes contaminated with wear or elastomeric seal debris, which changes the consistency of the lubricant and negatively affects the performance of the system.
The researchers discovered that used greases had a slightly harder consistency and darker color than new grease, but they were not contaminated with wear or seal debris.
In addition, the consistency of the grease indicated that several of the major failure modes of grease, including thermal and oxidation degradation, reaction of the base oil with water, and evaporation of base oil, did not occur.

The phenomenon observed among gear lubricants and greases when they thicken due to cold weather or other causes, to such an extent that a groove is formed through which the part to be lubricated moves without actually coming in full contact with the lubricant.

 Elements of Metric Gear Technology - QTC Q410-440, 441
Grease lubrication is suitable for any gear system that is open or enclosed, so long as it runs at low speed.
If the lubricants temperature is expected to exceed this limit, cooling fins should be added to the gear box, or a cooling fan incorporated into the system.
Lubricant is mixed with compressed air to form an oil mist that is sprayed against the contact region of the gears.

 Machinery Lubrication Magazine - lubricants, oil, maintenance
The goal of adequate lubricant viscosity was to build up a thin film of lubricant to prevent direct metallic contact between the rolling elements, raceways and cages.
Although the viscosity ratio is still a useful parameter, the complexity of grease lubricant performance with special additives, solids, thickeners, base-oil types and other factors is not fully represented.
After assessment, the grease lubricants are ranked according to their individual scores.

 Automotive lubricant engineering - Oil vs Grease, max roller bearing speeds?   (Site not responding. Last check: 2007-10-19)
Especially when the lubricant is needed to carry away heat generated elsewhere (heat generation in the bearing itself should not be a problem, unless you overfill the bearing) greases are unsuitable because they cannot act as a heattransportation medium.
A greased bearing may be able to run a very high speed and be ok temperature wise, but the grease life can still be short because of shearing.
One useful propety of greases is that in the high shear region within bearings and gears the viscosity of the grease approaches that of its base oil, whereas in the covers and housings, where the shear stress is low, grease tends to act as a seal.
