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 can be a QD or taper bushed style 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 produced 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 actually the measurement of the diameter of a circle tangent to the bottoms of the tooth spaces.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd number of teeth cannot be measured directly, caliper diameters will be the measurement across the tooth spaces almost opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle accompanied 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 exterior diameter may be the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It really is comparatively unimportant as the tooth length is not essential to correct meshing to with the chain. The exterior diameter may vary depending on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub in one side to another. This diameter should never go beyond the calculated diameter of the inside of the chain sidebars.
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) – Encounter width is limited in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the correct strength to transport the imposed loads.
Duration Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough key 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 lots of time and money. Additionally, the efficiency of a conveyor or drive depends on sprocket-chain conversation. Using the right sprocket is simply as important as choosing the right chain.

If at any point you have queries or difficulty finding or choosing your sprocket please get in touch with our customer service department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are created to run two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets 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. Stock sizes of double single sprockets range from ANSI #40 – #160 but additional sizes could be manufactured upon request. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets due to our quick reaction in-house machine store. Something important to note is that even though these sprockets are dual sprockets they will not double-strand roller chain. The charts below show the in-stock dual solitary sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to spell it out their sprockets. Though, throughout the general history of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or just “plate sprocket” is usually a flat 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 referred to as C-Hub sprockets can be 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 previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles as well as several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – 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 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’s machined in the sprocket. When the bushing is certainly inserted in to the sprocket can be 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 use a shear pin type hub that is bolted to a sprocket to provide an overload gadget. If the torque ranking is certainly 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 number, standardly the chain pitch will be created first, then your hub style or code, and accompanied by the number of the teeth the sprocket has. If the sprocket is multi strand there will frequently be considered a letter prefix at the start of the part quantity.
