Behind the part quantity a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed style the center letter for the hub designation is definitely changed to represent therefore.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is produced from a special material. This designation could be placed in the front 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 – Because the bottom level diameter (BD) of a sprocket with odd amount of teeth can’t be measured directly, caliper diameters will be the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle accompanied 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 is the measurement from the end of the sprocket tooth across to the corresponding stage directly over the sprocket. It really is comparatively unimportant as the tooth length is not vital to correct meshing to with the chain. The exterior diameter may vary based on the kind of cutter used. 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 surpass the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper strength. The dimensional allowance should be made for keyway and set screws.
Face Width (T) – Encounter width is bound in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimum width is bound to provide the correct strength to transport the imposed loads.
Size Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough key to withstand the torque transmitted by the shaft. This also steps 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 train sprockets, and changing them can cost considerable time and cash. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is just as important as selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and so are resilient. The roller chain sprockets for sale in our store include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets satisfy both ANSI and ASME requirements.
We’re positive you’ll end up being happy when you buy industrial chain sprockets inside our shop, 
One 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 one strand roller chain sprockets are manufactured with hardened the teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are completed with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Next select the type needed, finally select the preferred tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any point you have queries 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 created to operate two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets certainly are a style but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are produced with hardened the teeth and have a black oxide coating for superior performance and hook corrosion resistance. Share sizes of double one sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon demand. We can also supply quick response custom re-bores and MTO specialized double single sprockets because of our quick response 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 display the in-stock dual solitary sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “terms” 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 followed the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or simply “plate sprocket” is certainly 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 referred to as C-Hub sprockets can be 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 begins 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 – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are made to run two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” use a tapered bushing that is bolted in to the bore that’s machined in the sprocket. When the bushing is usually 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 delivers 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 gadget. If the torque ranking 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 created first, then the hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is multi strand there will most often be a letter prefix at the beginning of the part number.
