    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.

  • The Martin Quick Detachable bushings are easy to installand remove. They are split through flange and taper to pro-vide a true clamp on the shaft that is the equivalent of ashrink fit. All sizes except JA and H have a set screw overthe key to help maintain the bushings position on the shaftuntil the cap screws are securely tightened.

    Installation1. Be sure the tapered cone surfaces of the bushing and the

    inside of sprocket are clean. H2. Place bushing in sprocket, sheave, pulley, or other Martin

    QD parts. On M through S bushings, the mating part andbushing MUST be assembled so the two threaded holes inthe mating part are located as far as possible from the saw-cut in the bushing.

    3. Place cap screws and lock washers loosely in pull-upholes. Bushing remains fully expanded to assure sliding fiton shaft.

    4. With key on shaft, slide sprocket to desired position onshaft. Be sure heads of capscrews are on outside.

    5. Align sprocket. Tighten screws alternately and progres-sively until they are pulled up tight. To increase lever-age, use wrench or length of pipe (see wrench torquechart on pg. B-5). Do not allow sprocket to be drawn incontact with flange of bushing; there should be a gap of 18to 14 inch.

    CAUTION: When mounting screws, apply pressure by handonly. If extreme tightening forces are applied, bursting pres-sures will be created in the sprocket hub. There should be agap of 18 to 14 between the face of the sprocket hub and theflange of the QD bushing. This gap must not be closed. Ifthe gap is closed under normal tightening, the shaft is serious-ly undersized.

    4. Tighten pull-up bolts alternately and evenly to tighteness indicated in torque table below. Do not use extensions on wrench han-dles. There should be a gap between the face of the sheave or sprocket hub and the flange of the QD Bushing to insure a satis-factory cone grip and press fit. CAUTION: THIS GAP MUST NOT BE CLOSED.

    STANDARD MOUNTING REVERSE MOUNTING

    Bushing Installation TorqueWhen a wrench or length of pipe is used to increase leverage in tightening bushing screws, it is imperative to adhere to the wrenchtorque values given in the chart below.This adherence is important because, in mounting the bushing, the tightening force of the screw is multiplied many times by thewedging action of the tapered surface. This action compresses the bushing for a snug fit on the shaft. The bushing screws shouldalways be tightened alternately and progressively.

    REVERSE Mounting Assembly for QDSheaves and Sprockets using JA, SH,SD, SDS, SK, SF, E, F, & J BushingsThese bushings, as well as the sprockets and sheavesfor them, are each drilled with six holes (three drilledand three tapped) to allow pull-up bolts to be insertedfrom either side. This enables variations of mountingcharacteristics to suit a particular installation.

    DISMOUNTING1. Remove pull-up bolts and screw them into

    TAPPED holes in bushing flange andagainst hub of sheave or sprocket to breakcone grip.

    2. Loosen set screw in bushing flange andslide QD bushing from shaft.

  • To Install:1. Clean shaft, bore, and outside of bushing, and bore of hub

    (taking bushing from hub if already assembled). Removeany oil, lacquer, or dirt. Place bushing in hub and matchhalf holes to make complete holes (each complete holewill be threaded on one side only).

    2. Oil thread and point of set screws or thread and underhead of cap screws. Place screws loosely in holes thatare threaded on hub side (shown thus in diagram).

    3. Make sure bushing is free in hub. Slip assembly ontoshaft and locate in position desired.

    4.Tighten screws (see noteH ) alternately and evenly until allare pulled up very tightly. Use a piece of pipe on wrench toincrease leverage. (See table for wrench torque on reverseside.)

    5. Hammer against large end of bushing using hammer andblock or sleeve to avoid damage. Screws can now beturned a little more using the specified wrench torque.Repeat this alternate hammering and screw re-tighteninguntil the specified wrench torque no longer turns the screwsafter hammering. Fill other holes with grease to excludedirt.

    TaperBushings

    IMPORTANT: Follow all instructions in this manual carefully. This is necessary to insure satisfactory performance.

    To Remove:1. Remove all screws. Oil thread and point of set screws or

    thread and under head of cap screws.2. Insert screws in holds that are threaded on bushing side

    (shown thus in diagram). In sizes where washers arefound under screw heads, be sure to use these washers.Note that one screw in each hub is left over and is notused in this loosening operation.

    3. Tighten screws alternately until bushing is loosened inhub. If bushing does not loosen immediately, tap on hub.

    Recommended Wrench Torque

    When ordering Bushings give: Number stamped on large end of bushing, bore,and quantity.H If two bushings are used in the same sheave, pulley, or other unit member,tighten one bushing on shaft per steps 4 and 5 before starting to tighten screwsin other bushing.

  • 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.

    Handles All Combinations of Shock, Vibration, and Misalignment

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

    The axial f lexibil i ty 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 flexing characteris-tics of the sleeve and the lock-ing action of the teeth,QUADRA-FLEX couplingseasily handle angular mis-alignment up to 1 degree with-out any appreciable wear.

    QUADRA-FLEX sleeves aretorsionally resilient and arewell suited to absorbingshocks and dampening vibra-tions that would otherwise betransmitted between theequipment.

    SleeveSelection

    TPR(Sizes 3-10)

    QUADRA-FLEX couplingsare usually supplied with TPRsleeves in sizes 3-10. TPR isa general use sleeve whichcombines the characteristicsof both EPDM & Neopreneinto one. These sleeves oper-ate within a temperaturerange from -50 F to +275 F(-46 C to +135 C). Torsionalflexibility is 15.

    HYTRELH(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). Torsional flexibili-ty is 7.Note: Do not use a Hytrelsleeve as a replacement for aTPR, EPDM, or Neoprenesleeve.

    EPDM(Sizes 11-16)

    QUADRA-FLEX couplingsare usually supplied withEPDM rubber sleeves in sizes11-16. 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.

    NEOPRENEH(Sizes 13-16)

    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 four differ-ent types of compounds. These include TPR (ThermoPlasticRubber) in types JEM, JEMS, EM; EPDM Rubber in type E;

    Neoprene in type N; Hytrel in type H and HS. To determine thesleeve best suited for the application, the material characteris-tics are given below.

    SelectionProcedure

    Selection ProcedureWhen the driver is an electric motor with standard speed.

    Step 1. Determine Service Factor (SF) Symbol based on equip-ment 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 operating environ-ment found on page C-8, select from chart the type of sleevematerial. Find RPM of motor, then, in the column for service fac-tor determined in Step 2, read down to the corresponding horse-power of motor being used as the driver. The number listed isthe correct coupling size.

    Example: A coupling is needed to connect a 25 HP stan-dard electric motor to a lumber log haul at 1750 RPM.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-13 thru C-16, check cou-pling bore size range for proper shaft fit.

    H NOTE: Do not oversize coupling hub will cause premature wear of element.

    When the driver is other than an electric motor or thespeeds are different than those shown in the chart onpages C-8 and C-9.

    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 Table 2. Find a HP equal to orgreater 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. If maxi-mum is exceeded select the next largest size which will allow forbore size. Do not exceed maximum RPM for new size selected.

    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 the required 1.61 HP falls between the size 7 (1.2) and the size 8 (1.8). Correct selection is size 8 with TPR sleeve. Check bore sizes for flanges on pages C-11 thru C-13.
