Sprockets for 815, 820, and 881 are all double duty. Sprockets with odd numbers of teeth are recommended for longer wear sincea given tooth engages the chain every other revolution. Sprockets with 19, 21, 23, and 25 teeth are preferred. Sprockets with evennumber of teeth should be advanced one tooth periodically to attain even wear.

SPECIALTY Custom CapabilitiesForgings & Castings

ForgingsKnow how garnered through decades provides

unsurpassed benefit for the industrial user ofcustom forgings. This includes all phases in theforging process - die design and engineering,forging, coining, heat treating, and polishing.

Hammers ranging in size from 1,000 to 5,000pounds produce finished parts from a few ouncesto 50 pounds. Various alloys, the use of multi-cavity dies, expansive capacity, and secondarymachining capability enable Martin to deliver near100% density requirements in a cost effectivemanner.

Application: Counter weight on unit handlingequipment.

Problem: Parts were being milled in-housefrom purchased burned plate. Process wasexpensive, but low volumes had preventedconsideration of alternate methods ofmanufacture.

Solution: Instead of utilizating their expensiveCNC milling equipment on relatively low-techpart, Martin designed a simple die for a forgedpart, which worked well for medium quantityproduction runs. When compared to sourcingcosts, production time, and scrap, the forgedpart was less expensive than the milled part.The real savings has resulted from theenhanced utilization of the CNC millingequipment for other, more profitable work.

CastingsOperating its own foundry enables Martin to

provide its customers with quality assurance,quick lead times, and application engineeringassistance on cast and ductile iron parts.

With an upper range of 96 in diameter and10,000 pounds, our own pattern shop, andstreamlined access to secondary machining,Martins comprehensive capabilities serve abroad spectrum of industrial uses.

Application: Conveyor.

Problem: Redesign of equipment requiredflywheel and synchronous drive to be usedin more compact area. The two separatecomponents had clearance problems.

Solution: Martin designed a one piececasting which allowed machining of aduplex drive to fit in tight area. Equipmentis more compact, one final part rather thantwo saves costs, and installation time isreduced.

One of the many hammers capable of producingforgings up to 50 lbs.


Presses delivering more than 880 tons ofpressure form parts from bronze, iron,copper, manganese, etc.

SPECIALTY

Custom CapabilitiesSintered Metal

Sintered MetalCommonly associated with large quantity runs

of fairly simple products, the sintered metalprocess also effectively addresses smallquantities for many complex and multi-level partswhere intricate machining or milling was required.Smooth surface finishes, self-lubrication, andtolerance repeatability are just a few of theattributes resulting from this technology. Using awide range of alloys, Martin produces customsintered parts for many industries andapplications.

Application: Timing plate on an agriculturalimplement.

Problem: Production of parts requiredseveral steps. Purchase of disc blanks . . .Initial rough machining . . . Drilling holes . . .Milling slots and teeth . . . Application of rustinhibitor . . . Use of several outside sources.

All these factors led to inconsistenttolerances, difficulty in coordination of leadtimes, scrapped parts and productioninterruptions.

Solution: Martin reviewed sample parts andprints. Martin met with OEM engineering andservice personnel to better understand theapplication. The Martin sintered componentreduced the total cost of each part by anaverage of 54%, slashed acquisition costsand allowed for deliveries using stagedrelease dates.

Sintered metal is an excellent choice for a widevariety of products especially those with irregularshapes that would be difficult to manufactureusing conventional methods.

SPECIALTY Custom CapabilitiesInjection Molding

Injection MoldingSince the inception of our line of injection

molded plastic components, Martin has emergedas a leading supplier of cost effective non-metallic products.

A combination of polymers are used to achievedesired wear, corrosion resistance, and colorcharacteristics. Injection molded plastic is alsoadvantageous in non-sparking and sanitaryapplications.

While the final form of most components isachieved directly from the press, Martin is able toperform secondary machining on molded parts ifnecessary.

Application: Packaging equipment.

Problem: A sticky product required cleaningwith a caustic solution which led to corrosionbased fatigue of a threaded collar. Inaddition, high maintenance costs in the fieldwere encountered due to difficulty ofreplacing the seized collar.

Solution: A Martin manufactured part madeof glass filled nylon was produced. TheMartin part withstood constant exposure tothe caustic solution and prevented the seizingof threads which provided a longer part life.Unit price was reduced by approximately34%, warranty claims dropped significantlyand the user logo stamped on the part aidedin capturing replacement part sales.

One of the many injection molding machinesused to manufacture a variety of products.

Martin manufactures plastic products for bothpower transmission and non-power transmissionapplications.

IMPORTANT NOTE: Please follow the instructions on this sheet in order for the Martin bushing to perform satisfactorily.

INSTALLATION1 Clean all oil, dirt, and paint from shaft, bushing bore, outside of bushing and component (sprocket, sheave...etc.) bore.2 Insert bushing into component. Match the hole pattern, not the threaded holes (each hole will be threaded on one side only.)3. Thread set or cap screws into those half threaded holes indicated by on above diagram. Mount assembly on shaft.4. Alternately torque set or cap screws* to recommended torque setting in chart below. 5. On 3535 and larger bushings use a block, sleeve or drift and hammer large end of bushing (do not hammer bushing directly).6. Repeat steps 4 and 5 until torque wrench reading, after hammering, is the same as before hammering.7. Fill all unoccupied holes with grease.

REMOVAL1. Remove all set or cap screws.2. Insert set or cap screws in holes indicated by on drawing. Loosen bushing by alternately tightening set or cap screws.3. To reinstall, complete all seven (7) installation instructions.

BUSHINGS

Taper BushingsDimensions

Bushings cannot be bored larger than largest bore listed.

For detail dimensions required for machining hubs, consult factory.

Key furnished for these sizes only.

For general reference. Severe conditions may require larger hub. Heavy well-located web may permitsmaller hub. Hub diameter required depends on the particular application. Consult Martin giving full information on the proposed design. Hub diameters shown are based on 20,000, 30,000, and 50,000P.S.I. minumum ultimate tensile strength respectively for Class 20 gray iron, Class 30 gray iron, andsteel hubs.

2 screws required. Use in positions shown for tightening bushing on shaft. In removing bushing fromshaft, remove screws and use one of them in the other hole. Bushing price includes screws.

Space required to tighten bushing. Also space required to loosen screws to permit removal of hub by puller.

Space required to loosen bushing using one screw as jackscrew no puller required.

Martin Taper Bushed Type S Weld-On Hubs are suitable for use in many applicationssuch as for welding to plate steel sprockets. The outside diameters of these hubshave been reduced to a minimum. This is permissible because of the reinforcingstrength of the items to which they are to be welded. Cases where the attached itemis of small dimensions should be referred to Martin.

Type S Weld-On Hubs are made of steel, drilled, tapped, and taper bored for TaperedBushings. Their small size and the convenience and advantages of Taper Bushedconstruction make them of great value on many devices for use on shafts.

Martin QUADRA-FLEX Couplings, Non Lubricated,Maintenance Free, Easy and Quick Installation

Handles All Combinations of Shock, Vibration, and Misalignment

QUADRA-FLEX couplingsabsorb parallel misalignmentwithout wear and withminimal loss of energy.The amount of parallel offsethandled varies by size from.015 on the size 5 up to .062on the size 16. This minimizesthe radial loads on bearingswhen parallel misalignmentoccurs.

The axial flexibil ity of thesleeve allows the QUADRA-FLEX coupling to accept alimited amount of end float.This serves to reduce thrustloads transferred to bearings.QUADRA-FLEX units willaccept axial movement ofapproximately 1/8.

Due to the flexingcharacteristics of the sleeveand the locking action of theteeth, QUADRA-FLEXcouplings easily handleangular misalignment up to 1degree without anyappreciable wear.

QUADRA-FLEX sleeves aretorsionally resilient and arewell suited to absorbingshocks and dampeningvibrations that wouldotherwise be transmittedbetween the equipment.

SleeveSelection

TPR(Sizes 3-12)

QUADRA-FLEX couplingsare usually supplied with TPRsleeves in sizes 3-12. TPR isa general use sleeve whichcombines the characteristicsof both EPDM & Neopreneinto one. These sleevesoperate within a temperaturerange from -50 F to +275 F(-46 C to +135 C). Torsionalflexibility is 15.

*HYTREL(Sizes 6-14)

Hytrel sleeves are moldedspecifically for high torqueapplications. The type H willtransmit approximately fourtimes as much power as anequivalent TPR, EPDM, orNeoprene sleeve. Hytrel hasan operating temperaturefrom -65 F to +250 F (-54 Cto +121 C). Torsionalflexibility is 7.Note: Do not use a Hytrelsleeve as a replacement for aTPR, EPDM, or Neoprenesleeve.

EPDM(Sizes 13-16)

QUADRA-FLEX couplingsare usually supplied withEPDM rubber sleeves in sizes13-16. EPDM is a general usesleeve and can operate withina temperature range from-30 F to +275 F (-34 C to+135 C). Torsional flexibilityis 15.

NEOPRENE(Sizes 11-16)

Neoprene flexible sleeves arealso available in sizes 11-14.These sleeves offer a higherresistance than EPDM andare self-extinguishing. Oper-ating temperature range forthis sleeve is 0 F to +200 F(-18 C to +93 C). Torsionalflexibility is 15.

QUADRA-FLEX coupling sleeves are available in fourdifferent types of compounds. These include TPR(ThermoPlastic Rubber) in types JEM, JEMS, EM; EPDM

Rubber in type E; Neoprene in type N; Hytrel in type H and HS.To determine the sleeve best suited for the application, thematerial characteristics are given below.

SelectionProcedure

SelectionProcedureWhen the driver is an electric motor with standard speed.

Step 1. Determine Service Factor (SF) Symbol based onequipment listed on page C-10.

Step 2. Determine proper Service Factor from chart at top ofpage C-10.

Step 3. Refer to page C-12 and C-13 for proper selection ofcoupling. Based on chemical resistance and operatingenvironment found on page C-8, select from chart the type ofsleeve material. Find RPM of motor, then, in the column forservice factor determined in Step 2, read down to thecorresponding horsepower of motor being used as the driver.The number listed is the correct coupling size.

Example: A coupling is needed to connect a 25 HPstandard electric motor to a lumber log haul at 1750RPM.1. Service Factor Symbol H2. Service Factor 2.03. Coupling Size 9 with TPR sleeve or 6 with Hytrel

Sleeve

Step 4. Select flanges from pages C-15 thru C-19, checkcoupling bore size range for proper shaft fit.

NOTE: Do not oversize coupling hub will causepremature wear of element.

When the driver is other than an electric motor or the speedsare different than those shown in the chart on page C-11.

Step 1. Follow steps 1 & 2 in previous procedure.

Step 2. Calculate Horsepower at 100 RPM as follows:

HP at 100 RPM = HP x Service Factor x 100coupling RPM

Step 3. Select coupling size from Tables A or C. Find a HPequal to or greater than the HP/100 RPM

Step 4. Check Maximum bore to be sure that both shaft sizesdo not exceed figure listed for size selected in step 4. Ifmaximum is exceeded select the next largest size which willallow for bore size. Do not exceed maximum RPM for new sizeselected.

Example: A bucket elevator is driven by a motor/reducerand requires a coupling to transmit 14 HP at 1300 RPM.1. Service Factor Symbol M2. Service Factor 1.53. HP at 100 RPM = 14 x1.5 x 100 = 1.61 HP/100 RPM

1300

4. Refer to page C-11; under column for 100 RPM therequired 1.61 HP falls between the size 7 (1.2) and thesize 8 (1.8). Correct selection is size 8 with TPR sleeve.Check bore sizes for flanges on pages C-15 thru C-19.
