  3. 3. M O L Y K O T E ® T E C H N O L O G I E S F O R C H A I N L U B R I C A T I O N Brief Description of Machine Component Molykote® Book, Published by Dow Corning GmbH, Munchen C hain drives are used to transmit forces and motion between parallel shafts. They are used whenever spindle/shaft spacings have to be bridged which cannot be achieved with gear wheels or with belt drives because of unfavorable space or transmission conditions. Chain drives are preferred to as “positive envelope drives”. One or more sprockets are “enveloped” by an endless chain. They offer slip-free power transmission. If properly designed, they combine the advantages of a positive belt-drive with those of a positive gear wheel drive. Any shocks, which can endanger service reliability, are largely absorbed by chain drives, unlike spur gears, where elastic couplings have to be used. The mechanical efficiency of chain drives is ŋ = 0.93 to 0.99. A varietyof types of sprocket chains are used as drive chains or load chains for power transmissions, such as: Heavy duty roller chains; closed pitch or precision roller chains; flat top crate conveyor chains; ‘duplex’ or ‘triplex’ roller chains; malleable iron link chains; inverted-tooth or silent chains. Because of its versatility, the roller chain should be seen as the most important. Tribotechnical Design of Chains When lubrication is carried out with oils or greases, chains will operate in the mixed- friction range; with power transmission takes place both via the lubricant and the solid- body contact. For good tribological design, it is therefore important to keep wear caused by mixed-friction as small as possible, by using suitable lubricants. The lubricant must also meet secondary requirements relating to adhesion and oxidation resistance, in addition to the primary requirements.
  4. 4. M O L Y K O T E ® T E C H N O L O G I E S F O R C H A I N L U B R I C A T I O NPractical ApplicationVarious methods can be used to apply chain lubricants. This include:Manual Application; Drip-feed application; Splash lubrication in oil bath; Forced-feedcirculatory lubrication; Oil/air lubrication (spray lubrication); dry lubrication with anti-friction coatings.Minimising wear using specialty lubricantsIn the case of heavily loaded chains drives, high viscosities are used to minimize wear.Molykote® provides a The base oil viscosities are important. In addition, solidcomplete range of lubricants (mos2; colloidal graphite) are also used as additives.specialty lubricants for The service temperature of the lubricant must be considered asall chain applications one of the main criteria. Because of the greater proportion ofmixed friction, the decrease in viscosity at higher temperatures means greater wear onpins and bushes, and considerably limits the service life of a chain drive. Mineral oilsare not used elevated temperatures since gumming (resinification) occurs as low as 120degree C, which can affect chain flexibility. Synthetic oils with favourable viscosity-temperature properties are therefore used at high temperature ranges.
  5. 5. M O L Y K O T E ® T E C H N O L O G I E S F O R C H A I N L U B R I C A T I O NMolykote® TechnologiesDispersions Molykote® dispersions are finely divided solid lubricants suspended in lubricating fluids. They are preferred where it is necessary to apply solid lubricants in liquid form to units inoperation or to otherwise inaccessible points.Anti-friction Molykote® anti-friction coatings are similar to a lubricatingCoatings paint and contain a select blend of molybdenum disulphide and other solid lubricants dispersed in resinous or inorganic binder/solvent. They cure to form a dry, solid lubricant coatingthat is bonded to the surface. Dusty environment and inaccessible parts, which arelubricated for life, are ideal applications for anti-friction coatings.Greases Molykote® chain greases are fortified with molybdenum disulphide to provide effective lubrication under extreme load conditions. Molykote® grease formulations are available withmineral oil or synthetic oils. They contain adhesion improvers, corrosion inhibitors,solid lubricants and solvents, which assist penetration into critical areas such as linkpins.Oils Molykote® has an extensive range of chain oils in mineral and synthetic bases. Viscosity grades are available from 26 mm²/s to over 4000 mm²/s. They are available in food-grade and non-food grade formulations. Molykote® synthetic formulations contain thermally stableoxidation inhibitors and extreme pressure additives, and combine these with theirexcellent high temperature performance. They can be applied manually with brush,spray gun, or automatic lubricators using drip, jet or spray.Aerosols Molykote® aerosols are easy to use maintenance sprays available for quick lubrication of inaccessible points. They combine the Molykote® advantage of delivering solid lubricants in an easy touse spray can with carrier oils or solvents and high performance additive formulations.They provide excellent chain link penetration and adhesion and lubricity afterevaporation of the carrier oil or solvents.

  11. 11. Hints on repair and maintenanceThe service life of a chain can be increased considerably by using suitable lubricants underdifferent service conditions and observing the requisite relubrication periods. The principle causeof chain failure is excessive wear, resulting from improper lubrication or inadequate maintenance.If when checking the state of wear of the chain links, the chain has been stretched by more than2-3% of its initial length, it must be changed, otherwise differences in pitch will be producedbetween the links which can no longer be absorbed by the sprockets. Additional stresses andfriction moments are thereby generated, increasing the stress on the chain.A very dirty chain must be cleaned, to allow penetration of the lubricant. Suitable solvents such as1.1.1-trichlorethane or white spirit, or Dow Corning OS2 cleaner for precision chains, are used forthis purpose. After cleaning, the chain is dried with a lint free cloth.If the chain has to be fully lubricated, it must be removed, thoroughly cleaned and then immersedin chain greases, anti-friction coatings, high viscosity chain oils, etc to achieve complete lubricantpenetration.If dipping process is used, the dipping process should take place in such a way that the chainrollers are at right angles to the bottom of the dipping tank.Synthetic chain oils have a longer life at high temperatures, have greater oxidation stability andleave fewer combustion residues and decomposition particles.In drip-feed, the quantity of oil dependent on chain speed should be approx. 4 to 10 drops perminute. The quantity of oil must be increased for temperatures in excess of 60 degree C,In case of heavily loaded chain drives, high-viscosity lubricants are used to minimize wear. Inaddition, solid lubricants are used as additives.High centrifugal forces, such as occur at pinion and sprocket (reversing points) with fast-running chains, call for appropriate lubricant adhesion. Thin oils are thrown from the chainmuch more quickly than thick oils.BibliographyMolykote® Book, published by Dow Corning GmbH, 1991.Molykote® Catalog, Dow Corning Australia, Published 1990.Molykote® High Performance Industrial Lubricants Catalog Form # 71-0103J-01, Published 2002.Contact us atProject Sales Corp, 28 Founta Plaza, Suryabagh, Visakhapatnam 530020, AP.
