FEAFEAFEAFEAFEATURESTURESTURESTURESTURES

� SPROCKET TEETH ARE INDUCTION HARDENED AND/OR MADE FROMHIGH CARBON STEEL - Much longer life for sprocket and chain providing

lower maintenance costs.

� BOSSES ARE MACHINED AFTER WELDING - Holds axial alignment whenboring and keying resulting in longer sprocket wear life and the chain lastslonger.

� TRUE RUNNING - Pitch diameter is concentric to the bore which makesthe sprocket wear longer and chain last longer.

� KEYWAYS ON CENTER LINE OF TOOTH - (Solid and Welded) Allsprockets are timed to save the extra cost of made-to-order product whentiming is required.

� SOLID and WELDED CONSTRUCTION - Lower cost

� STOCK (OFF THE SHELF) - All sizes and up to 10 rows of teeth.ANSI & BS are ex-stock or available through weekly consolidated air freight.

� TOTAL QUALITY - Globally recognised market leader. You get a productthat consistently lasts longer and gives longer chain life.

� HEAT TREATABLE - Without carburizing. Most drive sprockets can behardened to 40 Rockwell C. The balance can be hardened as required(oil quench).

� MATERIALS USED:

Powered Metal - Higher nickel content self hardening, longest lifesprocket on the market BS (bored to size) series.

1144 Steel - 20 Rockwell C hardness which produces longer wear lifefor sprocket and chain (ANSI, A, B, C, BTB).

1045 Steel - 10 Rockwell C hardness which is higher than most otherdistributors producing longer wear life for sprockets andchain BS series.

Shear pin sprockets provide simple, dependable protection against expensive machinery damagecaused by overloads or jamming. Torque is transmitted by a single pin, necked to shear when thesafe load is exceeded. When an overload occurs, the pin shears, disconnecting the drive immediately.The Bolt-on Shear Pin Adapter converts any plate sprocket into a stock Shear pin sprocket allowingimmediate delivery of stock shear pin sprockets.

All stock sprockets are made of quality steel poured totheir specifications.

Bar size sprockets normally include sizes up to 7” or7½” in diameter type “B”, “BS”, “QD”, “TB” single, dou-ble and triple width. And can easily be electrical induc-tion or flame hardened - to Rockwell “C” 40 to 50.

Plate sprockets normally include sizes 7½” in diameterand larger type “B”, “BS”, “C”, “QD”, “TB” single, double,& triple width fabricated and type “A” all diameters. Thismaterial would have 35 to 40 points of carbon and canbe induction or flame hardened to Rockwell “C” 30 to 45.Degree of hardness obtainable and method depends onsize of sprocket.

Special quality steel can be used for large quantities ormade-to-order sprockets if specified.

HARDENING RECOMMENDHARDENING RECOMMENDHARDENING RECOMMENDHARDENING RECOMMENDHARDENING RECOMMENDAAAAATIONSTIONSTIONSTIONSTIONS

Hardened teeth substantially increases sprocket life andis recommended under conditions listed below:

1. Pinion or driver where the reduction is 4:1 orgreater.

2. Slow speed drives (100 FPM or less).3. Where safety factor is less than standard.4. Unusual abrasive conditions.

Degree of hardness - this is governed by conditionsprevailing each application - for shock sprockets thesegeneral suggestions may be used as guide lines:

1. Rockwell “C” 35 to 50 pinion or driver.2. Rockwell “C” 25 to 40 larger diameter or driver

sprockets.

Induction or flame hardening will be used as best suitedto the individual application. The diameter and pitch ofthe sprocket govern the method used.

Caution should be used to avoid “file hardness” (RockwellC 62 and above) as it is not recommended for Sprocketsdue to brittleness.

Depth of hardening should be limited so as to providecase only on the wear surfaces with a tough resilient coreto absorb shock. See figure below.

Note: Hardening cannot be accurately checked with a file—sta-tionary or portable hardness testers should be used for conclusiveresults.


Multiple Strand Sprockets

Listed using a letter prefix starting with the letter “D” for DoubleStrand, “E” for Triple Strand, and “F” for Quadruple, etc. Theyalso have the same hub configuration letter designation.

In addition to the four specific types, sprockets may also be madein various other styles.

Four common styles are:

1. The QD (quick detachable) sprocket

Here, a tapered bushing is bolted into the bore machined inthe sprocket. This bushing when inserted into the sprocketcompresses on to the shaft providing a tight grip.

2. The taperbushed sprocket is another style of an interchange-able bushed sprocket, which provides a positive grip on adriven shaft.

3. A shear pin type hub is bolted to a sprocket providing an over-load device; as sprocket torque ratings are exceeded the sheardevice disengages sprocket from drive.

4. A split type sprocket is used in place of solid type to allowquick installation without disruption of shaft and alignment.

SPROCKETS Sprocket Nomenclature

American sprocket manufacturers have adopted 4 specific typesof sprocket construction styles as American Standards. In addi-tion to the standard sprockets, special sprockets may be avail-able in the same styles.

Style A - Flat sprocket with no hub extension either side.

Style B - Sprocket with hub extension one side.Style C - Sprocket with hub extension both sides.Style D - Sprocket with a detachable bolt on hub attached

to a plate.

Sprocket nomenclatures provide the chain pitch written to theleft of the hub style code letter followed by the number of teeth inthe sprocket. If the sprocket is to be multiple strand, the prefixcode letter is added to the beginning of the part number.

A suffix of “H” is added if the teeth are to be heat treated. If thesprocket is to be bored for either QD or Taper bushed, the centerhub letter is changed. For QD style the letter designation of thebushing is used in lew of the hub style code. If a taper bushing isto be used, the two letters “TB” are added behind the hub codeletter.

In some instances, the material a sprocket is to be manufac-tured from will be added into the part number as a suffix.

For example:

Sprocket Dimensional Specifications

Bottom Diameter or BD : The Diameter of a circle tangent to the bottoms of the tooth spaces (orB.D.). P.D. - Chain Roller Diameter

Caliper Diameter : Since the bottom diameter of a sprocket with odd number of teeth cannotbe measured directly, caliper diameters are the measurement across thetooth spaces nearly opposite. P.D. - COS (π)

2 x Nt

Pitch Diameter : The diameter across to the pitch circle which is the circle followed by thecenters of the chain pins as the sprocket revolves in mesh with the chain (orP. D.).

PD = PITCH SIN (180/Nt)

Outside Diameter : The measurement from the tip of the sprocket tooth across to the corre-sponding point directly across the sprocket. It is comparatively unimpor-tant as the tooth length is not vital to proper meshing with the chain. Theoutside diameter may vary depending on the type of cutter used (or O.D.).

OD = (Pitch) (0.6 + COT [180/Nt])

Hub Diameter : That distance across the hub from one side to another. This diameter mustbe not to exceed the calculated diameter of the inside of the chain side bars(or H.O.D.).

Maximum Sprocket Bore : Maximum Sprocket Bore is determined by the required hub wall thicknessfor proper strength. Allowance must be made for keyway and setscrews.

Face Width : Face width is limited in its maximum dimension to allow proper clearance toprovide for chain engagement and disengagement. The minimum width islimited to provide the proper strength to carry the imposed loads.

Length Thru Bore : Length Thru Bore (or LTB) must be sufficient to allow a long enough key towithstand the torque transmitted by the shaft. This also assures stability ofthe sprocket on the shaft.

SPROCKETS Sprocket Nomenclature

If the part is to be used with a shear pin device, the center hubstyle letter is substituted with a “SP”.

Most manufacturers of sprockets conform to the ANSI (Ameri-can Standards Institute) and conforms to the Type II tooth formas given in the standard B29.1 - 1975. It is not necessary toshow detailed tooth information on sprocket drawings, justspecify ANSI standard tooth form.


Sprockets Technical InformationSPROCKETS

CENTER DISTANCE

The following general principals should be applied in determining shaft center distances. The centerdistance must always be greater than one-half the sum of the sprocket outside diameters to avoid inter-ference of teeth. When the speed ratio is greater than 3 to 1, the center distance should be not less thanthe sum of the sprocket diameters. Chain wrap should be at least 120° of the small sprocket - one-thirdof the teeth meshing.

Longer center distances give greater chain wrap. For average applications a center distance of 30 to 50pitches of chain is recommeded for best results. For pulsating loads, a center distance of 20 to 30 pitchesmay be desirable. For center distances of 80 pitches or greater, idlers or chain guides should be used tosupport the chain. Slightly adjustable center distances will provide chain tension as the chain elongateswith wear.

ALIGNMENT

Accurate alignment of shafts and sprocket tooth faces provide uniform distribution of the load across theentrire chain width and contributes substantially to optimum drive life. Shafting, bearings, and founda-tions should be suitable to maintain the initial alignment. Periodic maintenance should include aninspectionof alignment to insure optimum chain life.

LUBRICATION

TYPE A - Manual Lubrication

Oil applied periodically with brush or spout can.

TYPE B - Oil Bath or Oil Slinger

Oil level maintained in casing at predetermined height.

TYPE C - Oil Stream

Oil supplied by circulating pump inside chain loop on lower span.

NOTE: Drip Lubrication. Oil applied between link plate edges from a drip lubricator and should be usedin clean environments only.
