Roller chain sprocket

Behind the part quantity a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed design the guts letter for the hub designation is definitely changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the component quantity if the sprocket is manufactured from a special 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 spaces.
Caliper Diameter – Because the bottom diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters are the measurement across the tooth spaces nearly 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)
Outdoors Diameter (OD) The outside diameter is the measurement from the tip of the sprocket tooth across to the corresponding point directly across the sprocket. It is comparatively unimportant as the tooth size is not vital to proper meshing to with the chain. The outside diameter may vary depending on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub in one side to another. This diameter should never exceed 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 strength. The dimensional allowance must be designed for keyway and arranged screws.
Face Width (T) – Encounter width is bound in its optimum dimension to permit proper clearance to provide 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 should be sufficient to allow an extended enough crucial to withstand the torque transmitted by the shaft. This also actions 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 teach sprockets, and replacing them can cost lots of time and money. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to execute well under pressure and are resilient.

Our standard one strand roller chain sprockets are produced with hardened teeth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
To start shopping simply select what chain size you are employing 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 queries or problems finding or picking your sprocket please contact our customer support department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to operate two single-strand type roller chains, this is where the name “dual single” came from. Typically these sprockets are A style but both BTB taper bushed and QD design is available from share. Our double one sprockets are produced with hardened teeth and have a black oxide coating for superior performance and a slight 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 reaction custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine shop. Something vital that you note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below show the in-stock dual solitary sprocket sizes and also have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “conditions” or nomenclature to spell it out their sprockets. Though, throughout the general history 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 known as A-Plate or simply “plate sprocket” can be a set sprocket plate-wheel with no hubs that extrude on either side.
Style B, also known as B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also referred to as 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 will start with a prefix except when past 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles and also 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 design sprockets, also referred to as “quick detachable” utilize a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing is definitely inserted in to 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 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 provide an overload device. If the torque ranking is exceeded the shear gadget 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 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 is definitely multi strand there will frequently be a letter prefix at the beginning of the part quantity.
