Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is usually a QD or taper bushed style the guts letter for the hub designation is changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the part quantity if the sprocket is manufactured from a special material. This designation can be placed in leading of the part number or behind, if it is noted.
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth areas.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd amount of teeth cannot be measured directly, caliper diameters will be the measurement across the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle accompanied by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding stage directly across the sprocket. It really is comparatively unimportant as the tooth duration is not essential to proper meshing to with the chain. The outside diameter may vary depending on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub from one side to some other. This diameter should never exceed the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper strength. The dimensional allowance should be designed for keyway and arranged screws.
Face Width (T) – Encounter width is limited in its maximum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the proper strength to transport the imposed loads.
Size Thru Bore (L) – The space thru bore should be sufficient to allow a long enough key to withstand the torque transmitted by the shaft. This also actions the stability of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages can bring your machinery to a grinding halt. Many devices can’t operate without their drive train sprockets, and replacing them can cost considerable time and cash. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is simply as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to execute well under pressure and are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME criteria.
We’re positive you’ll end up being happy when you buy industrial chain sprockets inside our store, because they’ll last you quite a long time. If you’re uncertain what sprockets are the ones you need for your machine, make sure you don’t hesitate to give us a contact. Our knowledgeable staff, superior products, and unbeatable prices are the known reasons for our A+ BBB ranking!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete line of each type! Our standard solitary strand roller chain sprockets are produced with hardened the teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next choose the type needed, finally select the preferred tooth count and feasible accessories needed, then you are ready to get your sprockets! If at any point you have questions or difficulty finding or choosing your sprocket please contact our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to operate two single-strand type roller chains, this is where the name “double single” originated from. Typically these sprockets are A style but both BTB taper bushed and QD design is available from stock. Our double one sprockets are manufactured with hardened tooth and have a black oxide coating for excellent performance and hook corrosion resistance. Share sizes of double single sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon demand. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets because of our quick response in-house machine store. Something important to note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below display the in-stock double single sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to describe their sprockets. Though, through the entire general background of roller chain sprockets nearly every produce utilizes four various kinds of sprockets and has followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or just “plate sprocket” is usually a set sprocket plate-wheel without hubs that extrude on either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also referred to as C-Hub sprockets is usually a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub attached to a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles as well as many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to operate two single-strands of roller chain aspect parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also called “quick detachable” utilize a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is certainly inserted into the sprocket is certainly compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that provides a positive grip on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that is bolted to a sprocket to provide an overload gadget. If the torque rating can be exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part quantity, standardly the chain pitch will be written first, then your hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will frequently be considered a letter prefix at the start of the part number.
