881 for Side Flex Chain

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

Custom Capabilities Forgings & CastingsForgingsKnow how garnered through decades provides unsurpassed benet for the industrial user of custom forgings. This includes all phases in the forging process - die design and engineering, forging, coining, heat treating, and polishing. Hammers ranging in size from 1,000 to 5,000 pounds produce nished parts from a few ounces to 50 pounds. Various alloys, the use of multicavity dies, expansive capacity, and secondary machining capability enable Martin to deliver near 100% density requirements in a cost effective manner. Application: Counter weight on unit handling equipment. Problem: Parts were being milled in-house from purchased burned plate. Process was expensive, but low volumes had prevented consideration of alternate methods of manufacture. Solution: Instead of utilizating their expensive CNC milling equipment on relatively low-tech part, Martin designed a simple die for a forged part, which worked well for medium quantity production runs. When compared to sourcing costs, production time, and scrap, the forged part was less expensive than the milled part. The real savings has resulted from the enhanced utilization of the CNC milling equipment for other, more protable work. One of the many hammers capable of producing forgings up to 50 lbs.

CastingsOperating its own foundry enables Martin to provide its customers with quality assurance, quick lead times, and application engineering assistance on cast and ductile iron parts. With an upper range of 96 in diameter and 10,000 pounds, our own pattern shop, and streamlined access to secondary machining, Martins comprehensive capabilities serve a broad spectrum of industrial uses. Application: Conveyor. Problem: Redesign of equipment required ywheel and synchronous drive to be used in more compact area. The two separate components had clearance problems. Solution: Martin designed a one piece casting which allowed machining of a duplex drive to t in tight area. Equipment is more compact, one nal part rather than two saves costs, and installation time is reduced.

Custom Capabilities Sintered MetalSintered MetalCommonly associated with large quantity runs of fairly simple products, the sintered metal process also effectively addresses small quantities for many complex and multi-level parts where intricate machining or milling was required. Smooth surface nishes, self-lubrication, and tolerance repeatability are just a few of the attributes resulting from this technology. Using a wide range of alloys, Martin produces custom sintered parts for many industries and applications. Application: Timing plate on an agricultural implement. Problem: Production of parts required several steps. Purchase of disc blanks . . . Initial rough machining . . . Drilling holes . . . Milling slots and teeth . . . Application of rust inhibitor . . . Use of several outside sources. All these factors led to inconsistent tolerances, difculty in coordination of lead times, scrapped parts and production interruptions. Solution: Martin reviewed sample parts and prints. Martin met with OEM engineering and service personnel to better understand the application. The Martin sintered component reduced the total cost of each part by an average of 54%, slashed acquisition costs and allowed for deliveries using staged release dates. Sintered metal is an excellent choice for a wide variety of products especially those with irregular shapes that would be difcult to manufacture using conventional methods.

Custom Capabilities Injection MoldingInjection MoldingSince the inception of our line of injection molded plastic components, Martin has emerged as a leading supplier of cost effective nonmetallic products. A combination of polymers are used to achieve desired wear, corrosion resistance, and color characteristics. Injection molded plastic is also advantageous in non-sparking and sanitary applications. While the nal form of most components is achieved directly from the press, Martin is able to perform secondary machining on molded parts if necessary. Application: Packaging equipment. Problem: A sticky product required cleaning with a caustic solution which led to corrosion based fatigue of a threaded collar. In addition, high maintenance costs in the eld were encountered due to difculty of replacing the seized collar. Solution: A Martin manufactured part made of glass lled nylon was produced. The Martin part withstood constant exposure to the caustic solution and prevented the seizing of threads which provided a longer part life. Unit price was reduced by approximately 34%, warranty claims dropped signicantly and the user logo stamped on the part aided in capturing replacement part sales.

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

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

1 2 3. 4. 5. 6. 7.

INSTALLATION Clean all oil, dirt, and paint from shaft, bushing bore, outside of bushing and component (sprocket, sheave...etc.) bore. Insert bushing into component. Match the hole pattern, not the threaded holes (each hole will be threaded on one side only.) Thread set or cap screws into those half threaded holes indicated by H on above diagram. Mount assembly on shaft. Alternately torque set or cap screws* to recommended torque setting in chart below. On 3535 and larger bushings use a block, sleeve or drift and hammer large end of bushing (do not hammer bushing directly). Repeat steps 4 and 5 until torque wrench reading, after hammering, is the same as before hammering. Fill all unoccupied holes with grease. REMOVAL 1. Remove all set or cap screws. 2. Insert set or cap screws in holes indicated by G on drawing. Loosen bushing by alternately tightening set or cap screws. 3. To reinstall, complete all seven (7) installation instructions.

WARNING: Because of the possible danger to person(s) or property from accidents which may result from the improper use of products, it is important that correct procedures be followed: Products must be used in accordance with the engineering information specied in the catalog. Proper installation, maintenance and operation procedures must be observed. The instructions given above must be followed. Inspections should be made as necessary to assure safe operation under prevailing conditions. All rotating power transmission products when used in a drive are potentially dangerous and must be guarded by the user as required by applicable laws, regulations, standards, and good safety practice.

Bushings cannot be bored larger than largest bore listed. For detail dimensions required for machining hubs, consult Martin. For general reference. Severe conditions may require larger hub. Heavy welllocated web may permit smaller 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 50,000 P.S.I. minumum ultimate tensile strength respectively for Class 20 gray iron, Class 30 gray iron, and steel hubs. 3 screws for 6050; four for 7060 to 10085; six for 120100. Use in positions shown for tightening bushing on shaft. In loosening bushing, remove

screws and use all except one in the other holes. 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 screws as jackscrews no puller required. Not currently stocked Available on order.

Martin Taper Bushed Type S Weld-On Hubs are suitable for use in many applications such as for welding to plate steel sprockets. The outside diameters of these hubs have been reduced to a minimum. This is permissible because of the reinforcing strength of the items to which they are to be welded. Cases where the attached item is of small dimensions should be referred to Martin.Type S Weld-On Hubs are made of steel, drilled, tapped, and taper bored for Tapered Bushings. Their small size and the convenience and advantages of Taper Bushed construction make them of great value on many devices for use on shafts.

Handles All Combinations of Shock, Vibration, and Misalignment

ParallelQUADRA-FLEX couplings absorb parallel misalignment without wear and with minimal loss of energy. The amount of parallel offset handled varies by size from .015 on the size 5 up to .062 on the size 16. This minimizes the radial loads on bearings when parallel misalignment occurs.

AngularDue to the exing characteristics of the sleeve and the locking action of the teeth, QUADRA-FLEX couplings easily handle angular misalignment up to 1 degree without any appreciable wear.

TorsionalQUADRA-FLEX sleeves are torsionally resilient and are well suited to absorbing shocks and dampening vibrations that would otherwise be transmitted between the equipment.

AxialThe axial exibility of the sleeve allows the QUADRAFLEX coupling to accept a limited amount of end oat. This serves to reduce thrust loads transferred to bearings. QUADRA-FLEX units will accept axial movement of approximately 1/8.

QUADRA-FLEX couplings come in a variety of styles and designs to meet specic customer needs. These include anges and sleeves of various types and materials. The total product line includes 13 sizes varying in torque ratings up to 72,000 in-lbs. When ordering QUADRA-FLEX couplings, the following basic procedure should help expedite order processing. For coupling anges, give the basic coupling size, then the letter for the type ange followed by the bore size required. For coupling sleeves, give the coupling size followed by the letter(s) designating the type and material required. (See above) The following are various examples for reference: Example: Type J Flange Size 5 7 Flange J S Bore 3 4 30mm

Sleeve SelectionQUADRA-FLEX coupling sleeves are available in four different 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, the material characteristics are given below.

COUPLINGS

TPR(Sizes 3-12)QUADRA-FLEX couplings are usually supplied with TPR sleeves in sizes 3-12. TPR is a general use sleeve which combines the characteristics of both EPDM & Neoprene into one. These sleeves operate within a temperature range from -50 F to +275 F (-46 C to +135 C). Torsional exibility is 15.

EPDM(Sizes 13-16)QUADRA-FLEX couplings are usually supplied with EPDM rubber sleeves in sizes 13-16. EPDM is a general use sleeve and can operate within a temperature range from -30 F to +275 F (-34 C to +135 C). Torsional exibility is 15.

NEOPRENE(Sizes 11-16)Neoprene exible sleeves are also available in sizes 11-14. These sleeves offer a higher resistance than EPDM and are self-extinguishing. Operating temperature range for this sleeve is 0 F to +200 F (-18 C to +93 C). Torsional exibility is 15.

*HYTREL(Sizes 6-14)Hytrel sleeves are molded specically for high torque applications. The type H will transmit approximately four times as much power as an equivalent TPR, EPDM, or Neoprene sleeve. Hytrel has an operating temperature from -65 F to +250 F (-54 C to +121 C). Torsional exibility is 7. Note: Do not use a Hytrel sleeve as a replacement for a TPR, EPDM, or Neoprene sleeve.

Selection ProcedureSelection ProcedureWhen the driver is an electric motor with standard speed. Step 1. Determine Service Factor (SF) Symbol based on equipment listed on page C-10. Step 2. Determine proper Service Factor from chart at top of page C-10. Step 3. Refer to page C-12 and C-13 for proper selection of coupling. Based on chemical resistance and operating environment found on page C-8, select from chart the type of sleeve material. Find RPM of motor, then, in the column for service factor determined in Step 2, read down to the corresponding 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 HP standard electric motor to a lumber log haul at 1750 RPM. 1. Service Factor Symbol H 2. Service Factor 2.0 3. Coupling Size 9 with TPR sleeve or 6 with Hytrel Sleeve Step 4. Select anges from pages C-15 thru C-19, check coupling bore size range for proper shaft t. # NOTE: Do not oversize coupling hub will cause premature wear of element. 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 HP equal to or greater than the HP/100 RPM Step 4. Check Maximum bore to be sure that both shaft sizes do not exceed gure listed for size selected in step 4. If maximum is exceeded select the next largest size which will allow for bore size. Do not exceed maximum RPM for new size selected. Example: A bucket elevator is driven by a motor/reducer and requires a coupling to transmit 14 HP at 1300 RPM. 1. Service Factor Symbol M 2. Service Factor 1.5 3. HP at 100 RPM = 14 x1.5 x 100 = 1.61 HP/100 RPM1300

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 anges on pages C-15 thru C-19.
