Gear oils industrial

Viscosity improvers are primarily used in multigrade automotive engine oils, automatic transmission oils, power steering fluids, and gear oils. They also find use in aircraft and some industrial hydrauHc fluids for low temperature use. 

In addition to their automotive use, PAO oils also find appfication in industrial and aircraft hydraufic fluids, gear oils, compressors, and environmentally sensitive appfications. They are also used in multipurpose greases for army, navy, nuclear, and industrial appfications. Expanding use has led to a growth rate of PAO production from 1985 to 1990 of 19% per year (28). 

Although not widely used for gears, oil-mist lubrication is nevertheless worth mentioning here. It is a total loss technique in which the oil is supplied in the form of fine droplets carried by compressed air. Two virtues are that the lubricant can be carried long distances through pipes without severe frictional losses, and that no oil pumps are needed since the motive power is provided by factory compressed-air lines. However, unless such systems are totally enclosed, the exhaust can create a build-up of oil-mist in the atmosphere. In order to maintain good standards of industrial hygiene, it is recommended that...

Previous tests have shown that centrifugal pumps,6 the most reliable and most widely used pumps in the oil industry, are completely unsuitable for pumping oily-witer mixtures. While not entirely satisfactory, positive-displacement pumps, such as screw and gear pumps, cause less droplet breakup than most.

Ethanox 703 antioxidant is used as an oxidation inhibitor in natural and synthetic elastomers, polyolefin plastics, resins, adhesives, petroleum oil and waxes. Applications include steam turbine oils, hydraulic fluids, transformer oils, industrial gear oils and greases. 

The lower cost dialkyl benzenes are used in a wide variety of industrial and metalworking products. In particular, their sulphur-free chemistry has led to extensive use as rolling and drawing oils for copper. The synthesised alkyl benzenes, even when their chemistry is optimised, generally exhibit poorer properties than PAOs. However, their excellent solvency and low pour point make them suitable for lubricants designed for extremely low-temperature operations in arctic greases, gear oils, hydraulic and power transmission fluids. 

Typical application areas are industrial gear oils and greases, compressor lubricants, metalworking fluids, aqueous quenching fluids, fire-resistant hydraulic fluids, textile lubricants and heat transfer liquids. Section 2.7.5 gives a detailed account of these applications. 

To satisfy the specific needs of these applications, numerous detergent and dispersant substrates have been developed. The aim of this chapter is to highlight the synthesis and utility of the most industrially important of these. Emphasis will be given to engine lubricants since this application has the largest commercial demand for detergents and dispersants. But other key areas, such as gear oils, transmission fluids and fuels, are also considered. 

Over the years, detergents have found equally important usage in many other types of lubricants, including gear oils, farm tractor hydraulic fluids, automatic transmission fluids and industrial oils. The performance properties that detergents impart to these lubricating fluids include rust and corrosion prevention, improvement in lubricant elastomeric seal compatibility, enhancement of sludge control under oxidative conditions and improvement of wet clutch and wet brake friction level and stability. 

Together with engine oils, the other major industrial uses of dispersants are in automatic transmission fluids, gear oils and fuels. In general, the concepts developed in this chapter are also applicable to these applications.
