Behind the part number a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed design the center letter for the hub designation is definitely changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the part 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 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 number of teeth cannot be measured directly, caliper diameters will be the measurement over the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is the circle followed 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 outside diameter is the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It really is comparatively unimportant as the tooth size is not essential to correct meshing to with the chain. The exterior diameter may vary based on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub from one side to another. This diameter should never go beyond the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper strength. The dimensional allowance should be designed for keyway and arranged screws.
Face Width (T) – Encounter width is bound in its optimum dimension to permit proper clearance to provide for chain engagement and disengagement. The minimal width is bound to provide the correct strength to carry the imposed loads.
Duration Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough important 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 may bring your machinery to a grinding halt. Many machines can’t operate without their drive teach sprockets, and changing them can cost lots of time and cash. Additionally, the functionality of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is just 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 manufactured to perform well under pressure and are long lasting. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet both ANSI and ASME criteria.
We’re positive you’ll be happy when you buy industrial chain sprockets in our store, because they’ll last you quite a long time. If you’re not sure what sprockets are the ones you will need for your machine, please don’t hesitate to provide us a contact. Our knowledgeable staff, excellent products, and unbeatable prices will be the known reasons for our A+ BBB ranking!
SINGLE STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We share a complete line of each type! Our regular solitary strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used superior quality SAE 1045 steel material, and are completed with black-oxide for corrosion level of resistance.
To start shopping simply select what chain size you are employing with your sprocket. Next choose the type needed, finally select the desired tooth count and possible accessories needed, then you are ready to get your sprockets! If at any point you have questions or problems finding or choosing your sprocket please contact our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created to run two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from stock. Our double single sprockets are manufactured with hardened tooth and have a dark oxide coating for excellent performance and a slight corrosion resistance. Stock sizes of double single sprockets range from ANSI #40 – #160 but additional sizes could 
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 background of roller chain sprockets almost 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 simply “plate sprocket” is definitely 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 on one side.
Style C, also called C-Hub sprockets is certainly a sprocket with a hub that extrudes on both sides.
Style D, is a sprocket with a detachable bolt-on hub mounted on a plate.
MULTI-STRAND ROLLER CHAIN SPROCKETS
Multi strand roller chain sprockets will start with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles and also various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to run two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “quick detachable” utilize a tapered bushing that is bolted in to the bore that’s machined in the sprocket. When the bushing is certainly inserted into the sprocket is certainly compresses onto the shaft, which provides 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 is bolted to a sprocket to supply an overload device. If the torque rating is usually 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 number, standardly the chain pitch will be created first, then the hub design or code, and followed by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will most often be considered a letter prefix at the beginning of the part amount.
