Behind the part amount a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket can be a QD or taper bushed design the center letter for the hub designation is changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is manufactured from a particular material. This designation can be placed in the front of the part amount 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 spaces.
Caliper Diameter – Because the bottom diameter (BD) of a sprocket with odd amount of teeth can’t be measured directly, caliper diameters are 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)
Outdoors Diameter (OD) The exterior diameter is the measurement from the end 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 to with the chain. The outside diameter may vary based on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub from one side to another. This diameter should never exceed the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper strength. The dimensional allowance should be designed for keyway and arranged screws.
Face Width (T) – Face width is limited in its maximum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal width is limited to provide the proper strength to transport the imposed loads.
Length Thru Bore (L) – The length 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 devices can’t operate without their drive teach sprockets, and replacing them can cost a lot of time and money. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and so 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 meet both ANSI and ASME requirements.
We’re positive you’ll be happy when you buy industrial chain sprockets in our store, because they’ll last you a long time. If you’re uncertain what sprockets will be the ones you will need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, superior products, and unbeatable prices will be the known reasons for our A+ BBB ranking!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We share a complete type of each type! Our regular solitary strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used superior quality SAE 1045 metal material, and are finished with black-oxide for corrosion resistance.
To start shopping simply choose what chain size you are using with your sprocket. Next select the type needed, finally select the desired tooth count and possible accessories needed, then you are ready to get your sprockets! If at any stage you have questions or difficulty finding or selecting your sprocket please get in touch with our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to run two single-strand type roller chains, that’s where the name “dual single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD style is available from share. Our double one sprockets are manufactured with hardened tooth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double one sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We are able to also supply quick response custom re-bores and MTO specialty double single sprockets due to our quick reaction in-house machine shop. Something important to note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below show the in-stock double single sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to spell it out their sprockets. Though, through the entire general history of roller chain sprockets almost every manufacture 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 certainly a set sprocket plate-wheel with no hubs that extrude upon either side.
Style B, also known as B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also called C-Hub sprockets can be 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 
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Solitary (these sprockets are created to run two single-strands of roller chain side parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also called “quick detachable” use a tapered bushing that’s bolted into the bore that is 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 hold on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to provide an overload device. If the torque rating is certainly exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation without disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part quantity, standardly the chain pitch will be created first, then the hub style or code, and followed by the number of the teeth the sprocket has. If the sprocket can be multi strand there will most often be a letter prefix at the start of the part number.
