Roller chain sprocket

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 design the guts letter for the hub designation is certainly changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the component quantity if the sprocket is produced from a particular 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 spaces.
Caliper Diameter – Because the bottom diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters will be the measurement across the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is 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 exterior diameter is the measurement from the end of the sprocket tooth across to the corresponding stage directly over the sprocket. It is comparatively unimportant as the tooth duration is not essential to appropriate 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 over the hub in one side to some other. This diameter must not surpass the calculated diameter of the inside of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper power. The dimensional allowance should be made for keyway and arranged screws.
Face Width (T) – Encounter width is bound in its maximum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the proper strength to carry the imposed loads.
Size Thru Bore (L) – The distance thru bore must be sufficient to allow a long enough important 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 teach sprockets, and replacing them can cost a lot of time and cash. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain conversation. Using the proper sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and 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 meet both ANSI and ASME requirements.
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 will be 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 reasons for our A+ BBB rating!
One 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 single strand roller chain sprockets are produced with hardened the teeth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are completed with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Next select the type needed, finally select the preferred tooth count and possible accessories needed, then you are ready to get your sprockets! If at any stage you have queries or trouble 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 single sprockets are created to run two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD design is available from stock. Our double one sprockets are produced with hardened the teeth and have a black oxide coating for superior performance and hook corrosion resistance. Stock sizes of double one sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon demand. 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 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 double solitary sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures utilize different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the 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 called A-Plate or simply “plate sprocket” is usually 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 usually a sprocket with a hub that extrudes on both sides.
Design D, is a sprocket with a detachable bolt-on hub attached to 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 various other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – 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 side parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” utilize a tapered bushing that is bolted into the bore that’s machined in the sprocket. When the bushing is usually inserted into the sprocket is 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 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 provide an overload device. If the torque rating is exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation without disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part amount, standardly the chain pitch will be created first, then the hub design or code, and accompanied by the number of tooth the sprocket has. If the sprocket can be multi strand there will most often be considered a letter prefix at the beginning of the part quantity.
