Behind the part quantity 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 can be changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component quantity if the sprocket is manufactured from a special material. This designation could 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 areas.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters are the measurement over the tooth spaces nearly 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)
Outside Diameter (OD) The exterior diameter may be 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 size is not vital to appropriate meshing to with the chain. The outside diameter may vary depending on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub in one side to another. This diameter must not exceed the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension depends upon the required hub wall structure thickness for proper power. The dimensional allowance should be designed for keyway and set screws.
Face Width (T) – Face width is bound in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the correct strength to carry the imposed loads.
Duration Thru Bore (L) – The space thru bore should be sufficient to allow a long enough crucial to withstand the torque transmitted by the shaft. This also actions the balance of the sprocket on the shaft.
ANSI-CERTIFIED ROLLER CHAIN SPROCKETS
Industrial chain sprocket breakages may bring your machinery to a grinding halt. Many devices can’t operate without their drive train sprockets, and changing them can cost a lot of time and money. Additionally, the performance of a conveyor or drive depends on sprocket-chain conversation. Using the proper sprocket is just as important as choosing the right chain. At 
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 uncertain 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 products, and unbeatable prices will be the 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 standard one strand roller chain sprockets are produced with hardened teeth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are finished with black-oxide for corrosion level of resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next select the type needed, lastly select the desired tooth count and possible accessories needed, you then are ready to get your sprockets! If at any stage you have questions or difficulty finding or picking your sprocket please get in touch with our customer service department and we will be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are designed to operate two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets are A design but both BTB taper bushed and QD design is available from share. Our double solitary sprockets are manufactured with hardened teeth and have a black oxide coating for excellent performance and hook corrosion resistance. Share sizes of double single sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon request. We can also supply quick response custom re-bores and MTO specialized double single sprockets because of our quick reaction in-house machine store. Something vital that you note is that even though these sprockets are double sprockets they will not double-strand roller chain. The charts below display the in-stock double one sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, throughout the general background of roller chain sprockets almost every manufacture 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 definitely a set sprocket plate-wheel without hubs that extrude on 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 is a sprocket with a hub that extrudes on both sides.
Style D, is a sprocket with a detachable bolt-on hub attached to 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 many other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 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 referred to as “quick detachable” utilize a tapered bushing that’s bolted into the bore that’s machined in the sprocket. When the bushing is definitely inserted in to 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 use a shear pin type hub that is bolted to a sprocket to provide an overload device. If the torque rating is exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are manufactured for quick installation with no 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 the hub design or code, and followed by the number of the teeth the sprocket has. If the sprocket is definitely multi strand there will frequently be a letter prefix at the start of the part quantity.
