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.

Practical Application
Various methods can be used to apply chain lubricants. This include:
Manual Application; Drip-feed application; Splash lubrication in oil bath; Forced-feed
circulatory lubrication; Oil/air lubrication (spray lubrication); dry lubrication with anti-
friction coatings.
Minimising wear using specialty lubricants
In the case of heavily loaded chains drives, high viscosities are used to minimize wear.

one of the main criteria. Because of the greater proportion of
mixed friction, the decrease in viscosity at higher temperatures means greater wear on
pins and bushes, and considerably limits the service life of a chain drive. Mineral oils
are not used elevated temperatures since gumming (resinification) occurs as low as 120
degree C, which can affect chain flexibility. Synthetic oils with favourable viscosity-
temperature properties are therefore used at high temperature ranges.

Molykote® Technologies
Dispersions
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 in
operation or to otherwise inaccessible points.
Anti-friction Molykote® anti-friction coatings are similar to a lubricating
Coatings 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 coating
that is bonded to the surface. Dusty environment and inaccessible parts, which are
lubricated 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 with
mineral oil or synthetic oils. They contain adhesion improvers, corrosion inhibitors,
solid lubricants and solvents, which assist penetration into critical areas such as link
pins.
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 stable
oxidation inhibitors and extreme pressure additives, and combine these with their
excellent 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 to
use spray can with carrier oils or solvents and high performance additive formulations.
They provide excellent chain link penetration and adhesion and lubricity after
evaporation of the carrier oil or solvents.

Oil Molykote S 1500 series is a new line of high technology chain
oils introduced recently with the highest temperature resistance
and lower friction than comparable synthetic oils.
One of the effects of the temperature in a lubricant is its oxidation. The resistance of a
lubricant to oxidation can be measured by TG Analysis test. Molykote S-1502 from the
new line shows a 300% better resistance than other high quality synthetic chain oils.
Another important effect of the temperature in a lubricant is the evaporation. The
ASTM D 972/97 can measure this. The better resistance of the new Molykote chain
oils can represent a reduction of more than 600% of the evaporation.
The SRV ASTM D-5707 test measures the co-efficient of the function of a lubricant.
The new additive package of the Molykote® S-1503 and S-1504 allows a reduction of
the co-efficient of friction from a 0.10-0.12 of other competitors’ synthetic oils to 0.04.

11. Hints on repair and maintenance
The service life of a chain can be increased considerably by using suitable lubricants under
different service conditions and observing the requisite relubrication periods. The principle cause
of 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 than
2-3% of its initial length, it must be changed, otherwise differences in pitch will be produced
between the links which can no longer be absorbed by the sprockets. Additional stresses and
friction 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 as
1.1.1-trichlorethane or white spirit, or Dow Corning OS2 cleaner for precision chains, are used for
this 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 immersed
in chain greases, anti-friction coatings, high viscosity chain oils, etc to achieve complete lubricant
penetration.
If dipping process is used, the dipping process should take place in such a way that the chain
rollers 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 and
leave fewer combustion residues and decomposition particles.
In drip-feed, the quantity of oil dependent on chain speed should be approx. 4 to 10 drops per
minute. 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. In
addition, 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 chain
much more quickly than thick oils.
