Behind the part number a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is certainly 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 may also designate in the component quantity if the sprocket is produced from a special material. This designation could be placed in leading 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 – Since the bottom diameter (BD) of a sprocket with odd quantity of teeth can’t 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)
Outside Diameter (OD) The exterior diameter may be the measurement from the tip of the sprocket tooth across to the corresponding point directly across the sprocket. It really is comparatively unimportant as the tooth duration is not essential to correct meshing to with the chain. The exterior diameter may vary based on the type of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance over the hub from one side to some other. This diameter should never go beyond the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance should be designed for keyway and set screws.
Face Width (T) – Encounter width is bound in its optimum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the proper strength to transport the imposed loads.
Length Thru Bore (L) – The space thru bore should be sufficient to allow a long enough essential 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 can bring your machinery to a grinding halt. Many devices can’t operate without their drive teach sprockets, and changing them can cost a lot of time and money. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is just as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of regular roller chain sprockets at unbeatable prices. Our

DOUBLE SINGLE SPROCKETS
Double single sprockets are created to run two single-strand type roller chains, that’s where the name “double single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from share. Our double solitary sprockets are produced with hardened teeth and have a dark oxide coating for excellent performance and hook corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets because of 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 double solitary sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to spell it out their sprockets. Though, through the entire general history of roller chain sprockets almost every produce utilizes four different types of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or just “plate sprocket” is usually a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also called B-Hub sprockets is a sprocket with a hub that extrudes using one side.
Style C, also referred to as 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 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 several other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are made to operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD design sprockets, also known as “quick detachable” use a tapered bushing that’s bolted in to the bore that’s machined in the sprocket. When the bushing is usually inserted into the sprocket is certainly compresses onto the shaft, which gives a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another design of interchangeable bushed sprockets that delivers a positive grip on the driven shaft.
Shear Pin sprockets use a shear pin type hub that’s bolted to a sprocket to supply an overload device. 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 out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a component amount, standardly the chain pitch will be written first, then the hub design or code, and followed by the number of tooth the sprocket has. If the sprocket is usually multi strand there will frequently be a letter prefix at the start of the part amount.
