Behind the part number a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed style the center letter for the hub designation is certainly changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component amount if the sprocket is manufactured from a special material. This designation can be placed in leading of the part quantity or behind, if it is noted.
Bottom Diameter (BD) – This is actually the measurement of the diameter of a circle tangent to the bottoms of the tooth spaces.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd quantity of teeth cannot be measured directly, caliper diameters are the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle followed by the centers of the chain pins since the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The outside diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It is comparatively unimportant as the tooth duration is not essential to appropriate meshing to with the chain. The outside diameter may vary depending on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to some other. This diameter should never surpass the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper power. The dimensional allowance should be made for keyway and established screws.
Face Width (T) – Encounter width is bound in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the proper strength to carry the imposed loads.
Size Thru Bore (L) – The space thru bore must be sufficient to allow a long enough key to withstand the torque transmitted by the shaft. This also measures the balance of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages can bring your machinery to a grinding halt. Many machines can’t operate without their drive train sprockets, and replacing them can cost lots of time and money. Additionally, the functionality of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and so are long lasting. The roller chain sprockets for sale 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 in our store, because they’ll last you a long time. If you’re not sure what sprockets will be the ones you need for your machine, please don’t hesitate to give us a contact. Our knowledgeable staff, excellent products, and unbeatable prices are the known reasons for our A+ BBB ranking!
One STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete type of each type! Our regular one strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start out shopping simply choose what chain size you are using with your sprocket. Following choose the type needed, finally select the preferred tooth count and feasible accessories needed, you then are ready to get your sprockets! If at any point you have queries or trouble finding or selecting your sprocket please contact our customer support department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are designed to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD design is available from share. Our double one sprockets are produced with hardened tooth and have a dark oxide coating for superior performance and a slight corrosion resistance. Share sizes of double one sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets because of our quick response in-house machine store. Something vital that you note is that despite the fact that these sprockets are dual sprockets they will not double-strand roller chain. The charts below display the in-stock dual single sprocket sizes and 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, throughout the general history of roller chain sprockets nearly every produce utilizes four different types of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or just “plate sprocket” is usually a flat sprocket plate-wheel with no hubs that extrude upon 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 certainly a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub mounted on a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets begins with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles along with many other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to run two single-strands of roller chain side parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” make use of a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is certainly inserted in to the sprocket is definitely compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another style of interchangeable bushed sprockets that provides a positive hold on the driven shaft.
Shear Pin sprockets use a shear pin type hub that is 
bolted to a sprocket to provide an overload gadget. If the torque ranking is exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation with no disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part amount, standardly the chain pitch will be written first, then the hub style or code, and followed by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will frequently be considered a letter prefix at the beginning of the part quantity.
