Roller Chain technology has evolved over the centuries. During this time new designfeatures and production processes have been introduced.

Fenner Roller Chain is the product of this technology.

Increased Fatigue Resistance• Shot Peening of rollers and side plates

imparts beneficial fatigue resisting properties,

counteracting the onset of fatigue failure.

• Ball Swaged side plate holes improve the

hole quality and surface finish thus combating

fatigue failure.

• Deep Waisted side plates increase the

effective cross section of the side plate, thereby

providing additional resistance to fatigue failure.

Increased Wear Life• Seam Oriented Bushes ensure that

seams are positioned away from the critical

bearing areas, extending wear life thus

reducing down-time.

• Case Hardened Pins increase resistance towear, further extending wear life.

• Solid Rollers evenly distribute working loads,prolonging wear life.

Fit and Forget ReliabilityFenner Chain is preloaded to bed in all

component parts. This also acts as a final

100% quality check, enabling you to simply "fit

and forget" Fenner Chain.

Lubrication & ProtectionFenner Roller Chain is pre-lubricated for protection

against corrosion and contamination. The light

mineral oil used provides an initial lubrication,

however, FPT recommend that all chains should be

appropriately lubricated prior to operation.

Fenner Roller Chain is wrapped in a protective

covering and is boxed in 5 metre lengths.

Roller Chain Drive Selection

SELECTION

(a) Service Factor

From Table 1, determine the service factor whichis applicable to the drive.

(b) Design Power

Multiply the normal running power required by theservice factor. This gives the Design Power whichis used as the basis for selecting the drive.

(c) Chain Pitch

Refer to Table 2 (page 4) and trace to the rightalong the horizontal axis to the rev/min of the fastershaft. Trace upwards along the vertical axis to theDesign Power. At the point of intersection, notethe recommended chain pitch or pitches if thereis an overlap.

(d) Speed Ratio

Divide the speed of the faster shaft by the speedof the slower shaft to obtain the speed ratio.

(e) Sprocket Sizes

Refer to Table 4 (page 6) and select driving anddriven sprockets to match the Speed Ratio foundin step (d). See sprocket size recommendationson page 4.

(f) Power Rating

Refer to the power rating tables (page 5) for thepitch of chain chosen in step (c). Read down theleft hand column to the rotational speed of thefaster shaft. On this line read the power rating forthe simplex chain selected. These tables are for19 tooth sprockets, if a sprocket with a differentnumber of teeth is used, the power rating shouldbe multiplied by the Sprocket Factor from thetable at the bottom of page 5.

If the power rating figure does not equal orpreferably exceed the Design Power, calculatedin step (b), either select a larger pitch or a multiplestrand (duplex or triplex) chain.

Single strand chain offers the most economicalsolution, and should be used where possible.However, for limitations in space, high speed orsmooth running requirements a smaller pitch,duplex or triplex drive may be considered.

(g) Chain Length

To find the Chain length in pitches, use the formulabelow.

L = 2C + T + t + KP

P 2 C

L = Length of chain in pitches.C = Centre distance in mm.P = Pitch of chain in mm.T = Number of teeth on large sprocket.t = Number of teeth on small sprocket.K = Factor from Table 3 (page 6).

The calculated number of pitches should berounded up to an even, whole number of pitches.If the centre distance can not be adjusted, to allowfor the use of an even number of pitches, it maybe necessary to use an offset or cranked link, inwhich case the chain power rating will need to bereduced, consult FPT. Recalculate the exactcentre distance required for the adjusted numberof pitches. For recommended centre distance,refer to Table 5 below.

If a jockey or tensioning sprocket is used add anextra 2 pitches.

To obtain the chain length, multiply the number ofpitches by the pitch of the chain.

Length of chain in feet = LP

EXAMPLE

Select a chain drive to transmit 1.5 kW from agearbox running at 80 rev/min and driven by adirect-on-line electric motor to a uniformly loadedconveyor drive shaft which is required to run atapproximately 40 rev/min for 12 hours per day.Gearbox output shaft is 35mm and the headshaftis 65mm diameter.

(a) Service Factor

From Table 1 the Service Factor is 1.2.

(b) Design Power

= 1,5 x 1,2 = 1,8 kW.

(c) Chain Pitch

By referring to Table 2 (page 4), the intersectionof design power and the rev/min of the faster shaftindicates a 16B 1” pitch chain.

(d) Speed Ratio

80

40 = 2:1

(e) Sprocket Size

From Table 4 (page 6) sprockets of 19 and 38teeth give a ratio of 2 : 1.

(f) Power Rating

The power ratings for 16B chain are given on page5. The required power rating from step (b) is 1.8kW. For a 19T driver sprocket, running at 80 rev/minute, the power rating for 16B-1 simplex chain

is 3.79 kW. As this exceeds the required designpower the selection is satisfactory.

If space limitations demand smaller sprocketdimensions, an alternative selection would be touse 12B-2 duplex chain which has a power ratingof 2.11 kW at 80 rev/min.

g) Chain Length

Recommended centre distance for 16B-1 chain is1000 mm Table 5 below.

Therefore the chain length as per selection step(g) (chain length) is 108 pitches including aconnecting link.

TABLE 2 - BRITISH STANDARD CHAIN

Rev/min of FASTER SHAFT

GENERAL RECOMMENDATIONS ON SPROCKET SIZES

19 teeth and above —

Sprockets running at medium to maximumspeeds on normal applications (see powerratings for speeds on page 5).

17 teeth —

Permissible to use this sprocket on very smallpitches ie, 8mm and 3/8". Refer to section above,but should be restricted to slow speed drives(see power ratings for speeds on page 5).

15 teeth or less —

Must be avoided unless shaft speed is below100 revs/min.

23 teeth and above —

Recommended for impulse applications.

When ratios are low, the use of sprockets with highnumbers of teeth minimises joint articulation, chainpull and bearing loads. If a small number of teeth areused on high speed, high load applications,hardening of teeth should be considered. Ratios over7:1 are not recommended for single strand drives. Inall drives where ratios exceed 5:1 the designershould consider using compound drives formaximum service life.

On drives where ratios exceed 3:1 the shaft centredistance should not be less than the sum of thesprocket pitch circle diameters.

For drives with vertical shafting always use multi-strand chains.

AMERICAN STANDARD ROLLER CHAINS

Note; Refer to FPT for dimensional details of ANSI "H" Series multiple strand chain

"H" SERIES ROLLER CHAINS

ANSI “H” Series chains are dimensionally identical toANSI standard chains except that the sideplates arethicker. The heavier side plates provides some additionalfatigue resistance. They are primarily intended forapplications where occasional shock loads are likely tocause fatigue failures in the chain. Whilst there is anincrease in tensile strength, the wear life of the casehardened pins remains the same as for standard chain.

Simplex “H” series chains operate on standard ANSIsprockets. Multiple strand “H” chain require non-standard ANSI sprockets because of the thicker sideplates.

"SH" SERIES ROLLER CHAINS

ANSI “SH” series chains are identical to “H” seriesbut they have a different pin material, which is throughhardened. The surface hardness is less than that ofthe carburised pins in the ANSI standard and ANSI “H”series chains but through hardened pins provideadditional fatigue resistance, at some slight sacrificein wear life.

Simplex “SH” series chains operate on standard ANSIsprockets. Multiple strand “SH” series chain requirenon-standard ANSI sprockets because of the thickerside plates.

INSTALLATION NOTES

• Shafts must be parallel with bearingsand supporting structures of sufficientrigidity to maintain true alignment.

• Mount sprockets as close as possibleto bearings.

• Check correct alignment of eachsprocket by use of a straight edge.

Roller chain can be used in practically anyposition provided the shafts are parallel. Onfixed centre drives the effect on the slackstrand must be carefully considered.

Where the slack strand is nearly vertical, orwhere torque variation causes wave orwhip in the chain, an idler must be used totake up the excessive slack. The idlershould preferably be near to the largersprocket in the drive, located on theoutside of the slack strand of the chain.Where layout makes this impossible it ispermissible to locate the idler on the insideof the chain.

LUBRICATION

Effective lubrication is essential in order toensure optimum wear life from any chain.

To be effective it must form a film oflubricant between the wearing parts, (thepin and bush), of the chain. It hastherefore to be of suitable viscosity and bedelivered to the gap between thesideplates such that it can penetrate intothe space between the pin and bush. Theviscosity, amount and type of lubricant isgoverned by the size of chain and theoperating conditions involved. Oil will onlypenetrate into the bearing area of the chainwhen the chain is slack, therefore oilshould be delivered to the slack strand justafter the driver sprocket.

High speed drives are especially critical.These generally require a continuousstream of lubricant applied across the fullchain width in order to act as a coolant aswell as lubricating the bearing area.

Three basic lubrication methods arerecommended for use with Fenner RollerChain.

TYPE 1 Drip Feed (for linear chain

speeds up to 1 mtr/sec.)

Oil drops directed between the side plategaps with a drip feed lubricator. Brushapplicators may also be used, providedthey are positioned to ensure that the oil iscorrectly delivered to the gap between theside plates. Volume and frequency shouldbe sufficient to prevent discolouration ofthe lubricant in the chain joints. Anydiscolouration of the lubricant or of the pin

will indicate insufficient lubricationpenetrating into the bearing area. Airmovement, due to the motion of the drive,can disturb and mis-direct the oil drops,therefore, with due regard for safety, checkthe applicator while the drive is running.

TYPE 2 Oil Bath or Disc Lubricator

(for linear chain speeds up to

6 mtrs/sec.)

With oil bath lubrication the lower strand ofchain runs through an oil sump. With thechain running, the oil level in the sumpshould immerse the chain at its lowestpoint. The oil level and condition of the oilshould be checked periodically to ensuresufficient volume of oil is present and thatit has not emulsified or becomecontaminated.

A disc or oil slinger may also be used. Inwhich case the disc picks up oil from thesump and deposits it on the chain, usuallythrough a trough. The chain operatesabove the oil level. The diameter of thedisc should be sufficient to ensure a rimspeed between 3 and 15 m/s.

TYPE 3 Pump and Sump (for high

speed drives).

Oil is pumped from the sump by acirculating pump capable of delivering aconstant stream of oil, evenly distributedacross the full width of the chain. The oilshould be supplied on the inside of thechain loop and at the lower strand, whenchain speeds exceed 100 m/s.

CHAIN TENSION

Chains should be fairly tight at installationwith only a small amount of slack. Withvertical drives the chain should be keptsnug. After the first few weeks ofoperation, re-check chain tension andadjust if necessary.

FIXED CENTRE APPLICATIONS

An idler sprocket is generallyrecommended for fixed centre drives. Itshould be positioned on the slack side asclose to the larger sprocket as feasible. Thetensioning sprocket should have aminimum of three teeth engaged and be aminimum of four links away from thenearest sprocket.

Installation Instructions

TO INSTALL

1. After ensuring that the mating taperedsurfaces, bore and shaft are completelyclean and free from oil or dirt, insertbush in hub so that holes line up.

2. Sparingly oil thread and point of grubscrews, or thread and under head ofcap screws. Place screws loosely inholes threaded in hub, shown thusin diagram.

3. If a key is to be fitted place it in theshaft keyway before fitting the bush. Itis essential that it is a parallel key andside fitting only and has TOPCLEARANCE.

4. Clean shaft and fit hub to shaft as oneunit and locate in position desired,remembering that bush will nip theshaft first and then hub will be slightlydrawn on to the brush.

5. Using a hexagon wrench tightenscrews gradually and alternately totorque shown in table below.

6. Hammer against large-end of bush,using a block or sleeve to preventdamage. (This will ensure that the bushis seated squarely in the bore.) Screwswill now turn a little more. Repeat thisalternate hammering and screwtightening once or twice to achievemaximum grip on the shaft.

7. After drive has been running under loadfor a short time stop and checktightness of screws.

8. Fill empty holes with grease to excludedirt.

TO REMOVE

1. Slacken all screws by several turns,remove one or two according tonumber of removal holes shown thus•in diagram. Insert screws into removalholes after oiling thread and under headof cap screws.
