No matter how good it is, any rollerchain falls short of being the best if itisnt available when and where itsneeded. A-1 Many diverse elements go into eachlink of roller chain. Engineering ability.Material quality. Manufacturing technologies. Worker skills. And, everychain manufacturer has the sameopportunity to select the elements which constitute his product.Link-Belt roller chain has chosen toproduce only the best.Doing that requires the highest qualitymaterials, designed and improved bythe best engineering minds, and manufactured by the industrys mostadvanced and precise processes. It requires...

Standard roller chain is broadly used in power transmission applications ranging from general industrialapplications to demanding oil fieldservice to operation in such specialied areas as food processing and heavyconstruction equipment.Single and multiple standard rollerchains, available in 14 sies, meetmost drive requirements. Specificationsare shown on pages B-1 through B-3.Double-pitch drive chains frequentlyprove the economical choice for slowerspeed drives on relatively long centers.For details, see page B-6.Modifications of these chains,developed for special operating conditions, are described...

Standard and double-pitch conveyorchains are available with a selection ofattachments to accommodate slats,angles, rollers, crossrods, and other conveying devices. Youll find details onthese widely used conveyor chains andattachments on pages D-3 through D-8.Conveyor chain design modificationsto meet specific applicationrequirements are described below. > Double-pitch roller chain with large- diameter rollers combines smooth,quiet operation and long life. Thismodification proves particularly useful in applications requiring minimumlubrication or where conditions makelubrication difficult. See...

Typical drive arrangements using chain tighteners are shownin the preferred drive arrangements below. Dimensions ofseveral chain tightener brackets are listed on page C-49.Offset links may be used to adjust chain length when othermeans are not available. Single-pitch offset links and two-pitch offset assemblies can be supplied. Offset assembliesare recommended for high speed or heavily loaded drives.Chain tension should be carefully maintained when thefollowing operating conditions exist:Fixed centersVertical or near vertical centersShock or pulsating loadsReversals in direction of rotation Center...

Other arrangements These arrangements are not gener-ally recomended but they will give satisfactory service ifcarefully attended and chain tension is accurately maintained.Establish the material or design variation factor When avariation of standard roller chain is being selected (such as stainless steel chain for corrosion resistance), refer to Table3 and determine the appropriate variation factor. This factorcompensates for either the design or material difference so that a selection can be made from the standard roller chainrating table. Calculate the equivalent horsepower Multiply thehorsepower...

Determine the number of teeth for the large sprocket Multiply the drive ration by the number of teeth in the smallsprocket.If the drive is to operate in a restricted location, check thesprocet radii against the space limitation. Radial clearancerequired for each sprocket is equal to one-half the sum of its pitch diameter and the chain pitch. Encased drives require anadditional 3" radial clearance. If sufficient space is notavailable, consider a smaller pitch, multiple strand drive. Check the small sprocket As shown in the rating table, themaximum bore of a 17-tooth No. 100 sprocket is larger than...

Disc lubrication is very effective formoderately high-speed drives and is frequently used when the drivearrangement is not suitable for oil bathlubrication. An oil disc mounted on the lowersprocket dips about one-half inch intoan oil reservoir. The oil is thrown off thedisc by centrifugal force, automatically lubricating the chain which is keptabove the oil level. This method oflubrication is ineffective at high speeds as well as at very low speeds.Oil disc lubrication is applicable to therelative shaft positions illustrated below: Forced lubrication is recommendedfor large horsepower drives,...
