Behind the part amount 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 guts letter for the hub designation is changed to represent therefore.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the part quantity if the sprocket is manufactured from a special 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 areas.
Caliper Diameter – Since the bottom diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters are the measurement over 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 since 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 across the sprocket. It is comparatively unimportant as the tooth length is not essential to correct 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) – Is the distance across 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 is determined by the required hub wall structure thickness for proper power. The dimensional allowance must be designed for keyway and set 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 limited to provide the correct strength to carry the imposed loads.
Duration Thru Bore (L) – The distance thru bore must be sufficient to allow a long enough key to withstand the torque transmitted by the shaft. This also procedures 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 teach sprockets, and replacing them can cost lots of time and money. Additionally, the performance of a conveyor or drive depends upon sprocket-chain interaction. Using the proper sprocket is simply as important as selecting the most appropriate chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to perform well under pressure and so are resilient. 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 satisfy both ANSI and ASME criteria.
We’re positive you’ll be happy when you get industrial chain sprockets inside our shop, because they’ll last you a long time. If you’re uncertain what sprockets are the ones you need for your machine, make sure you don’t hesitate to give us a contact. Our knowledgeable staff, superior items, and unbeatable prices are the known reasons for our A+ BBB ranking!
Solitary STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We share a complete line of each type! Our regular single strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used high quality quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start shopping simply select what chain size you are employing with your sprocket. Following select the type needed, lastly select the preferred tooth count and possible accessories needed, you then are ready to get your sprockets! If at any point you have queries or trouble finding or picking your sprocket please get in touch with our customer service department and 
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to operate two single-strand type roller chains, that’s where the name “dual single” came from. Typically these sprockets are A design but both BTB taper bushed and QD style is available from share. Our double solitary sprockets are manufactured with hardened the teeth and have a dark oxide coating for superior performance and hook corrosion resistance. Share sizes of double single sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. 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 vital that you note is that even though these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below show the in-stock dual single sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to describe their sprockets. Though, through the entire general history of roller chain sprockets almost every produce utilizes four various kinds of sprockets and has adopted 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 on either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes on one side.
Style C, also called C-Hub sprockets is definitely 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 will start with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four standard styles and also several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” make use of a tapered bushing that’s bolted in to the bore that’s machined in the sprocket. When the bushing is inserted into the sprocket can be compresses onto the shaft, which provides 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 use a shear pin type hub that is bolted to a sprocket to supply an overload gadget. If the torque rating is definitely 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 amount, standardly the chain pitch will be written first, then your hub style or code, and followed by the number of teeth 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 quantity.
