Behind the part amount 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 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 component number if the sprocket is manufactured from a particular material. This designation can be placed in the front of the part number or behind, if it’s noted.
Bottom Diameter (BD) – This is the measurement of the diameter of a circle tangent to the bottoms of the tooth areas.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd number 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 may be the circle followed by the centers of the chain pins because the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside 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 size is not vital to appropriate meshing to with the chain. The exterior diameter may vary depending on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to some 
Maximum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper power. The dimensional allowance should be made for keyway and arranged screws.
Face Width (T) – Face width is bound in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the proper strength to transport the imposed loads.
Duration Thru Bore (L) – The distance thru bore should be sufficient to allow an extended enough important to withstand the torque transmitted by the shaft. This also steps 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 changing them can cost considerable time and cash. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is simply as important as selecting the most appropriate chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are manufactured to execute well under pressure and so are long lasting. The roller chain sprockets accessible in our shop 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 be happy when you buy industrial chain sprockets inside our store, because they’ll last you quite a long time. If you’re not sure what sprockets will be the ones you need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, excellent items, and unbeatable prices are the known reasons for our A+ BBB rating!
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 single strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used high quality 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 employing with your sprocket. Next select the type needed, finally select the desired tooth count and possible accessories needed, you then are ready to get your sprockets! If at any stage 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 single sprockets are created to run two single-strand type roller chains, that’s where the name “dual single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double one sprockets are manufactured with hardened tooth and have a dark oxide coating for superior performance and hook corrosion resistance. Share sizes of double single sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets due to our quick reaction in-house machine store. Something important to note is that despite the fact that these sprockets are double sprockets they will not double-strand roller chain. The charts below display the in-stock double solitary 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, through the entire general history of roller chain sprockets nearly every produce utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” is definitely a set sprocket plate-wheel without 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 is usually 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 in addition to many other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double Single (these sprockets are created to operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” use a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing is definitely inserted into the sprocket is usually 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 is bolted to a sprocket to supply an overload device. If the torque ranking is exceeded the shear gadget 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 the teeth the sprocket has. If the sprocket can be multi strand there will frequently be a letter prefix at the beginning of the part quantity.
