Bolt-On Shear Pin Sprockets Shear Pin sprockets provide simple, dependable protection against expensive machinery damage caused by overloads or jamming. Torque is transmitted by a single pin, necked to shear when the safe 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 allowing immediate delivery of stock Shear Pin sprockets. Selection guide on page E-6 gives complete procedure to select the proper Shear Pin assembly.

Bolt-On Shear Pin Sprockets Shear Pin Sprocket Selection. The shear pin assembly required is determined by the shaft size. Select the smallest shear pin assembly which will accommodate the required bore. Table on page E- contains the bore ranges and minimum sprocket sizes which allow chain clearance over the shear pin assembly flange. 2. Using one of the following formulas, compute the torque load the pin must transmit and find the value in the torque rating table below to obtain the proper shear pin neck diameter. T = HP x 6,02 x. or T = D x CP x. RPM 2 or T = Output of reducer x speed ratio of chain drive x. Where: T = Torque in pound inches HP = Horsepower at Sprocket RPM = Sprocket Speed D = Pitch Diameter of Sprocket CP = Chain pull in pounds. = Safety factor for starting load Example:. Determine the shear pin assembly and pin neck diameter to transmit 20 horsepower at 67 RPM with a 4 tooth, No. 00 sprocket on a 2 6" shaft. () Referring to Table I (page E-), shear pin assembly SP-2 is required for a 2 6" bore. The 4 tooth sprocket is well above the minimum size. (2) Torque and neck diameter: HP x 6,02 x. T = RPM T = 20 x 6,02 x. = 28,200 lb. in. 67 Referring to Table II (page E-) under SP-2, a pin necked to " shows a torque rating of 29,80 lb. in., which exceeds the 28,200 lb. in. required.

Solid and Split Detachable Hubs Type D Sprockets Stock Detachable Hubs Type D sprockets consist of a Type A plate sprocket bolted to a detachable hub. A solid or split plate sprocket may be assembled to a solid or split hub. When ordering a Type D sprocket, be sure to select a plate sprocket large enough to allow chain clearance over the hub flange diameter, dimension D. Bolt holes of Type D hubs are drilled for interchangeability. Speed ratios may be changed simply by removing the plate sprocket and substituting another with a different number of teeth. When worn, the sprocket may be reversed to use the unworn tooth surfaces, increasing the life of the sprocket.

Torque-Limiter Clutches Martin TORQUE-LIMITER clutch offers thrifty overload protection that s easy to adjust. Non-Asbestos Friction Discs Pressure Plate Spring Washer Long-Life Bushing More Adjustment Capability with Spline Hub Sprocket Adjustment Nut Setscrew Cap Screw Spring Compression Torque-Limiter clutches may be used with a sprocket, gear, sheave, flange, or other driven member. It is recommended that the rubbing sides of the driven member be ground to provide a smooth rubbing surface of 6 to 2 micro-inches. See torque rating table on following page. The driven member is mounted on an oil-impregnated bushing and clamped between two, high quality friction discs by spring pressure. Each Torque-Limiter unit, completely assembled, contains one spring. Higher torque ratings can be obtained by the use of a second spring nested within the original spring. See rating table on following page. When an overload occurs, the driven member slips between long-life, clutch-type friction discs. After slipping has started, it will continue at approximately 90% of the torque setting, due to the lower coefficient of friction when slipping, until the overload condition has been corrected. Here is low cost protection for your machinery... a torque limiting clutch that is easy to install. Torque-Limiter clutches feature an exclusive Easy-Set Adjustment. With Easy-Set, torque adjustment is accomplished quickly! The need for hammer and block, brute strength, and spanner wrenches is eliminated. These simple steps and the job is done:. Snug up the adjusting nut, finger tight, locate set screw over nearest spline notch, and tighten. See table at right. 2. Tighten three cap screws until heads bottom with a small wrench; this gives maximum torque.. For less torque back off the cap screws, loosen the set screw, back off adjusting nut to one of the six spline notches as required, and retighten set screw and cap screws. Easy-Set Adjustment not only simplifies installation, it provides solid support for pressure plates by compression at their peripheries. The Torque-Limiter clutch gives machinery permanent protec - tion against overloads during starting, reversing, or driving by slipping at any desired load. It resumes driving without resetting when the overload is relieved. It is simple in design, compact, efficient, and built for long life. It provides low cost torque limiting service for a wide variety of applications. No lubrication... minimum maintenance. Starting shock from electric motors is a major cause of maintenance of moving parts. Torque-Limiter clutches provide a cushion by slipping until the torque drops to a pre-set level. They can be set to reduce shock loads on motors and driven equipment during reversing or inching. They provide mechanical protection against breakage due to sudden overload by slipping when the pre-set torque limit is reached. TORQUE (lb.-ins.)

Double Pitch All Steel Stock Sprockets Standard Roller Double Duty Carrier Roller Double-Pitch Sprockets Double Pitch Single Duty Standard Rollers Made-To-Order Carrier Rollers Series C-2000 chains have rollers of the same diameters and widths as American Standard Roller Chains of one half the conveyor chain pitch. Engaged by every other tooth, double duty sprockets have two teeth per chain pitch. During each revolution only half the teeth function effectively. Sprockets with odd numbers of teeth will allow any given tooth to engage only on every other revoution, automatically increasing sprocket life. Double duty sprockets with even number of teeth may be manually advanced one tooth periodically to increase sprocket life. Martin Stock C-2000 series sprockets are furnished double duty only. Sprockets for the C-2002 series chain with carrier rollers are cut with space cutters or standard hobs for the American Standard roller Chain of the same diameter. Each sprocket tooth meshes with these chains. Double-duty sprockets cannot be made for double pitch chain with Carrier Rollers. NOTE: For drives of teeth or more we recommend using Standard sprockets with series C-2000 chains. All altered double pitch sprockets requiring a keyway will be furnished with keyway on center line of tooth, unless otherwise specified. E-

Engineering SPROCKET ENGINEERING DATA ROLLER CHAIN DIMENSIONS SPROCKET TOOTH DIMENSIONS MAXIMUM HUB RECOMMENDATIONS APPLICATION AND SELECTION HARDENING CHAIN LENGTH CALCULATION SPEED RATIOS SPROCKET DIAMETERS HORSEPOWER RATINGS American sprocket manufacturers have adopted 4 specific types of sprocket construction styles as American Standards. In addition to the standard sprockets, special sprockets may be available 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. LTB Pitch Dia. Outside Dia.

Multiple Strand Sprockets - Listed using a letter prefix starting with the letter D for Double Strand, E for Triple Strand, and F for Quadruple, etc. They also have the same hub configuration letter designation listed on previous page. In addition to the four specific types, sprockets may also be made in various other styles. Double Sprocket Nomenclature Triple Five common styles are: QD The QD (quick detachable) sprocket; here a tapered bushing is bolted into the bore machined in the sprocket. This bushing, when inserted into the sprocket, compresses onto the shaft providing a tight grip. MST The MST (Martin Split Taper ) is another style of bushed sprocket. The bushing is similar to the QD style except it has an external key that fits into the driven product. HOD Bore TB The TB (taper bushed) sprocket is another style of an interchangeable bushed sprocket, which provides a positive grip on a driven shaft. Length Thru Split A split type sprocket is used in place of solid type to allow quick installation without disruption of shaft and alignment. Shear Pin Sprocket A shear pin type hub is bolted to a sprocket providing an overload device; as sprocket torque ratings are exceeded the shear device disengages sprocket from drive. E-

Sprocket Nomenclature Sprocket nomenclatures provide the chain pitch written to the left of the hub style code letter followed by the number of teeth in the sprocket. If the sprocket is to be multiple strand, the prefix code 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 the sprocket is to be bored for QD, Taper Bushed or MST, the center hub letter is changed. For QD and MST styles the letter designation of the bushing is used in lieu of the hub style code. If a taper bushing is to be used, the two letters TB are added behind the hub code letter. In some instances, the material a sprocket is to be manufactured from will be added into the part number as a suffix. For example: SS - Stainless Steel Material NM- Non-Metallic BR - Brass or Bronze Material CD - Cadmium Plated Zi - Zinc Plated Ni - Nickel Plated CH - Chrome Plated If the part is to be used with a shear pin device, the center hub style letter is substituted with an SP. Most manufacturers of sprockets conform to the ANSI (American Standards Institute) and conforms to the Type II tooth form as given in the standard B29. - 97. It is not necessary to show detailed tooth information on sprocket drawings, just specify ANSI standard tooth form. Face Width Caliper Diameter Bottom Dia. Bore Pitch Dia. Outside Dia.

Sprocket Nomenclature Sprocket Dimensional Specifications Bottom Diameter - The diameter of a circle tangent to the bottoms of the (B.D.) tooth spaces. Caliper Diameter - Since the bottom diameter of a sprocket with odd number of teeth cannot be measured directly, caliper diameters are the measurement across the tooth spaces nearly opposite. Pitch Diameter - The diameter across to the pitch circle which is the circle (P.D.) followed by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD = PITCH SIN (80/Nt) Outside Diameter - The measurement from the tip of the sprocket tooth () across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth length is not vital to proper meshing with the chain. The outside diameter may vary depending on type of cutter used. OD = (Pitch) (.6 + COT [80 / Nt]) Hub Diameter - That distance across the hub from one side to another. (HOD) This diameter must not exceed the calculated diameter of the inside of the chain side bars. Maximum Sprocket - Maximum Sprocket Bore is determined by the required Bore hub wall thickness for proper strength. Allowance must be made for keyway and setscrews. Face Width - Face width is limited in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimum width is limited to provide the proper strength to carry the imposed loads. Length Thru Bore - Length Thru Bore (or L.T.B.) must be sufficient to allow (LTB) a long enough key to withstand the torque transmitted by the shaft. This also assures stability of the sprocket on the shaft. E-

Sprocket Selection Application Data and Selection Procedure How to Check Horsepower Rating of Installed Drive. Determine the types of driving and driven loads and obtain the proper service factor, as explained in Steps and 2 under Selection Procedures. 2. Find the multiple strand factor, for the number of chain strands in the drive, from the Multiple Strand Factor Table, in Horsepower Tables (Page E-86 thru E-92).. From the horsepower rating table for the chain pitch, read the figure under the RPM of the small sprocket and to the right of the column giving number of teeth in the small sprocket. 4. The horsepower this drive can properly transmit is as follows: HORSEPOWER Rating Table Multiple Strand DRIVE CAN = ( Horsepower ) X ( Factor ) TRANSMIT Service Factor Center Distance The following general principals should be applied in determining shaft center distances. The center distance must always be greater than one-half the sum of the sprocket outside diameters to avoid interference of teeth. When the speed ratio is greater than to, the center distance should be not less than the sum of the sprocket diameters. Chain wrap should be at least 20 of the small sprocket one-third of the teeth meshing. Longer center distances give greater chain wrap. For average applications a center distance of 0 to 0 pitches of chain is recommended for best results. For pulsating loads, a center distance of 20 to 0 pitches may be desirable. For center distances of 80 pitches or greater, idlers or chain guides should be used to support the chain. Slightly adjustable center distances will provide chain tension as the chain elongates with wear. Alignment Accurate alignment of shafts and sprocket tooth faces provide uniform distribution of the load across the entire chain width and contributes substantially to optimum drive life. Shafting, bearings, and foundations should be suitable to maintain the initial alignment. Periodic maintenance should include an inspection of alignment to insure optimum chain life. Design Horsepower When making drive selections consideration is given to the loads imposed on the chain. Service factors based on the type of equipment to be driven (Table I, Page E62) and the type of input power (Table II, Page E62) are used to compensate for these loads. Horsepower Rating Tables The horsepower ratings in this catalog apply to lubricated single pitch, single strand precision roller chains, both standard and double pitch roller chain. The ratings reflect a service factor of, a chain length of approximately 00 pitches, use of recommended lubrication methods, and a drive arrangement where two aligned sprockets are mounted on parallel horizontal shafts. The horsepower ratings relate to the speed of the smaller sprocket and drive selections are made on this basis, whether the drive is speed reducing or speed increasing. For ratings of multiple strand roller chains refer to Multiple Strand Factor in Horsepower Tables. Lubrication It has been shown that a separate wedge of fluid lubricant is formed in operating chain joints much like that formed in journal bearings. Therefore, fluid lubricant must be applied to assure an oil supply to the joints and minimize metal to metal contact. Lubrication, if supplied in sufficient volume, also provides effective cooling and impact damping at the higher speeds. For this reason, it is important that the lubrication recommendations be followed. The horsepower rating tables shown throughout this catalog, apply only to drives lubricated in the manner specified in the tables. Chain drives should be protected against dirt and moisture and the oil supply kept free of contamination. Periodic oil change is desirable. A good grade of non-detergent petro leum base oil is recommended. Heavy oils and grease are generally too stiff to enter and fill the chain joints. E-60

Application Data and Selection Procedure Sprocket Selection Types of Lubrication There are four basic types of lubrication for chain drives. The recommended type shown in the horsepower rating tables is influenced by chain speed and the amount of power transmitted. These are minimum lubrication requirements and the use of a better type (for example, Type C instead of Type B) is acceptable and may be beneficial. Chain life can vary appreciably depending upon the way the drive is lubricated. The better the lubrication, the longer the chain and sprocket life. For this reason, it is important that the lubrication recommendations be followed when using the rating tables given in this catalog. 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 used in clean environments only. Most roller chain drive applications allow considerable latitude in the selection of sprocket sizes and chain pitch, although usually one combination will best fulfill the requirements of power, speed, space limitations and economy.

Some of these conditions are listed below:. Multiple Shafts add.2 for each additional shaft. 2. Excessive speed ratios exceeding 7 to.. Heavy starting loads with frequent starts and stops. 4. Conditions of high temperatures, unusually abrasive conditions, or circumstances decreasing lubrication effectiveness or not allowing the use of recommended lubrication procedures. Step IV Step V Determination of Design Horsepower Determine the design horsepower of the required drive using the following procedure.. Determine Service Classification Table I. Unlisted equipment may be classified by its similarity to a listed type. 2. Using Service Classification and Frequency of Service, select the Service Factor Table II. Increase the Service Factor by adding compensation for unfavorable operating conditions.. Multiply the normal operating horsepower of the drive by the Compensated Service Factor to obtain Service Horsepower. Drive Selection Using Design Horsepower computed above, use Trial Selection Chart (Horsepower Tables) on page E84-E8, or enter tables of Horsepower Ratings shown on pages E86 thru E92. Select the smallest pitch chain which has the required horsepower rating for a pinion sprocket turning at the specified RPM. Check to be certain the selected sprocket has a listed maximum bore large enough to accom modate the specified shaft. The tables on pages E-8 thru E-9 gives maximum bores for the usual range of driving sprockets. If the Design Horsepower at the required RPM is greater than the horsepower rating of the largest pitch chain which can operate at that speed, a multiple chain drive should be considered for the application. Selection of drives to operate at speeds somewhat below the maximum rating will increase the life of the drive and quietness of operation. Driving Sprocket In selecting the driving sprocket 7 teeth are recommended as a minimum although teeth are quite often used, and as low as 7 teeth can be cut. When the maximum bore of the 7 tooth sprocket will not accomodate the driving shaft, it is necessary to go to a sprocket with a greater number of teeth. Hardened teeth are recommended for sprockets with 2 teeth or less. E-62

Application Data and Selection Procedure Sprocket Selection Step VI Step VII Step VIII Driven Sprocket (Ratio) The number of teeth selected for the driven sprocket depends upon the driving sprocket chosen and the desired speed of the driven shaft. When space limitations are a factor, the diameter of the driven sprocket sometimes determines the final selection of drive. The recommended maximum speed ratio is 7 to, although higher ratios are occasionally used. It is usually better design, however, for large reductions to use a double reduction drive. Select the driven sprocket size from the Speed Ratio Table on page E-70 using the required speed ratio and size of driver sprocket. Shaft Centers May be calculated from the formula on page E-68 where the sprocket diameters and chain length are known. On many applications the motor base is adjustable, allowing for slight changes in shaft centers. On long centers some form of chain adjuster or take-up is recommended. Chain Length On page E-68 is shown a simple method of computing the length of chain necessary for a drive with given sprocket dimensions and center to center distance of shafts. (See chart on page E-69 for length in ft.) Chain Drive Design Example To select a roller chain drive from a 0 HP electric motor ( '' shaft) 200 RPM (0 under load) to a wood working machine shaft at 00 RPM on 0'' centers. Drive conditions moderate pulsating load, good lubrication, 0 hour day operation.. Service class moderate shock load (Table I). 2. Service factor. (Table II).. Design HP. x 0 = DHP. 4. Selection The Horsepower Ratings on page E-84 show that either of the following combinations may be used. No. D40-9 Tooth Smoothest in operation No. 0-8 Tooth Lower drive cost For our purpose we select No. 0 chain and checking the bore find that the " shaft can be accommodated with a stock bored to size sprocket. The driven sprocket is found as follows: No. Teeth Driven Sprocket = 8 x 0 (Ratio) = 68.99 or 69 Teeth 00 Since 69 teeth is not a stock size we select 70 teeth. The chain length is calculated as shown on page E-69 and is 42 pitches. Overhung Load When a Sprocket is mounted on a reducer shaft, a calculation should be made to determine the overhung load in pounds using formula on page i-2 in general engineering section. E-6

Sprocket Engineering Engineering Data & Design Horsepower equals,000 foot pounds per minute, or 0 foot pounds per second. In terms of chain load and speed. HP = or HP = Working Load x Ft. Per Min.,000 Working Load x T x P x R.P.M. 96,000 Where T = number of sprocket teeth P = chain pitch Chain Working Load when the horsepower input is known and the chain working load is desired, this can be calculated as follows: Working Load = or = HP x,000 Ft.

Torque is usually expressed in inch pounds. Torque (Driving Shaft) Torque (Driven Shaft) = HP x 6,000 R.P.M = Working Load R Where a crank arm is used the load transmitted by the arm can be determined as follows: Crank arm Load = Driven Shaft Torque r or = ChainiWorking Load x R r Catenary Tension imposed by reason of the weight of chain can be approximated as follows: W x L Catenary Tension = 2 8 x S + (W x S) where W = weight of chain (lbs. per ft.) S = chain sag (feet) = 2% to % of shaft centers approx. L = Shaft centers in feet. E-64

Sprocket Engineering Engineering Data & Design Conveyor Chains Chains used in the design of conveyors should be selected on the basis of the chain pull imposed by the application and the permissible or maximum working load of the chain. In some instances a larger pitch chain than is necessary may be selected due to the desired attachment spacing, and the effect in this case would be to increase the life of the conveyor. HORIZONTAL CONVEYORS Chain Pull The force or pull required to move a conveyor includes the pull necessary to move the weight of chain and material and the frictional resistance of the chain parts on the runways. The following formulas may be used in calculating the total chain pull. The same formula applies in the case of single or parallel strand chain conveyors, but in the case of parallel strand conveyors, the pull per chain is one-half of the figure calculated from the formula. INCLINED CONVEYORS Total pull of chains = f H (W + P) NOTE: When lower strand of conveyor drags on runway above formula becomes f H (W + 2P). VERTICAL CONVEYORS Total pull of chains = V (W + P) H (feet) = Horizontal projection of conveyor length. V (feet) = Vertical projection of conveyor length. W (pounds) = Weight of material handled per foot of conveyor length. P (pounds) = Weight per foot of all moving conveyor parts (single or two strand). f = Coefficient of friction of chain on runway. Total pull of chains = f H (W + P) + V (W + P) NOTE: When lower strand of conveyor drags on runway the factor P (f H V) should be added to above formula unless V is greater than f H. Value of Coefficient F Sliding steel on iron or steel...2% Rolling friction...% (If material or other than the usual chain parts are in contact with the runway, the coefficient should be increased to compensate for the added resistance.)

Bar size sprockets normally include sizes up to 7" or 7 2" in diameter type B, BS, QD, TB single, double & triple width. And can easily be electrical induction or flame hardened to Rockwell C 40 to 0. Plate sprockets normally include sizes 7 2" in diameter and larger type B, BS, C, QD, TB single, double, & triple width fabricated and type A all diameters. This material would have to 40 points of carbon and can be induction or flame hardened to Rockwell C 0 to 4. Degree of hardness obtainable and method depends on size of sprocket. Special quality steel can be used for large quantities or madeto-order sprockets if specified. Hardening Recommendations Hardened teeth substantially increases sprocket life and is recommended under conditions listed below:. Pinion or driver where the reduction is 4: or greater. 2. Slow speed drives (00 FPM or less).. Where safety factor is less than standard. 4. Unusual abrasive conditions. Degree of hardness this is governed by conditions prevailing each application for stock sprockets these general suggestions may be used as guide lines:. Rockwell C to 0 pinion or driver. 2. Rockwell C 2 to 40 larger diameter or driver sprockets. Induction or flame hardening will be used as best suited to the individual application. The diameter and pitch of the sprocket govern the method used. Caution should be used to avoid file hardness (Rockwell C 62 and above) as it is not recommended for sprockets due to brittleness. Depth of hardening should be limited so as to provide case only on the wear surfaces with a tough resilient core to absorb shock (see illustration tooth section). Note: Hardening cannot be accurately checked with a file stationary or portable hardness testers should be used for conclusive results.
