Behind the part amount 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 design the guts letter for the hub designation is certainly changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures will also designate in the part number if the sprocket is manufactured from a particular material. This designation could be placed in the front of the part number or behind, if it is 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 diameter (BD) of a sprocket with odd amount of teeth cannot be measured directly, caliper diameters are the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which is 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 outside diameter may be the measurement from the end of the sprocket tooth across to the corresponding stage directly across the sprocket. It really is comparatively unimportant as the tooth size 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 across the hub from one side to some other. This diameter must not exceed the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper power. The dimensional allowance should be made for keyway and set screws.
Face Width (T) – Face width is bound in its optimum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is bound to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The distance thru bore must be sufficient to allow a long enough crucial to withstand the torque transmitted by the shaft. This also procedures the stability 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 changing them can cost a lot of time and money. Additionally, the efficiency of a conveyor or drive depends upon sprocket-chain conversation. Using the proper sprocket is just as important as deciding on the best chain.

DOUBLE SINGLE SPROCKETS
Double one sprockets are made to operate two single-strand type roller chains, this is where the name “double single” originated from. Typically these sprockets certainly are a style but both BTB taper bushed and QD design is available from share. Our double one sprockets are produced with hardened tooth and have a dark oxide coating for excellent performance and hook corrosion resistance. Share sizes of double single sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon demand. We can also supply quick reaction custom re-bores and MTO specialty 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 double one sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of 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 just “plate sprocket” is definitely a flat sprocket plate-wheel with no 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 called C-Hub sprockets is certainly 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 begins with a prefix except when previous 4-strands. We supply single through twelve (12) strand roller chain sprockets in the four regular styles in addition to various other styles upon request.
D – Double Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – 4 Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are made to operate two single-strands of roller chain part parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also called “quick detachable” make use of a tapered bushing that is bolted into the bore that is machined in the sprocket. When the bushing can be 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 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’s bolted to a sprocket to provide an overload device. If the torque ranking 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 component number, standardly the chain pitch will be written first, then your hub design 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 start of the part amount.
