Behind the part quantity a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed design the center letter for the hub designation is definitely changed to represent therefore.
Regular 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 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 diameter (BD) of a sprocket with odd amount of teeth can’t be measured directly, caliper diameters are the measurement across the tooth spaces almost 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 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 appropriate meshing to with the chain. The exterior diameter may vary based on the kind of cutter used. 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 exceed the calculated diameter of the within of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall structure thickness for proper power. The dimensional allowance must be made for keyway and established screws.
Face Width (T) – Face width is bound in its optimum dimension to allow proper clearance to provide for chain engagement and disengagement. The minimal 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 an extended enough key 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 machines can’t operate without their drive train sprockets, and replacing them can cost lots of time and money. Additionally, the efficiency 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 
We’re positive you’ll be happy when you buy industrial chain sprockets in our shop, because they’ll last you a long time. If you’re not sure what sprockets are the ones you will need for your machine, make sure you don’t hesitate to give us a call. Our knowledgeable staff, superior items, and unbeatable prices are the reasons for our A+ BBB ranking!
Solitary 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 standard single strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are completed with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are employing with your sprocket. Next choose the type needed, lastly select the preferred tooth count and possible accessories needed, then you are ready to get your sprockets! If at any point you have questions or problems finding or picking your sprocket please get in touch with our customer service department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to run two single-strand type roller chains, this is where the name “dual 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 manufactured with hardened tooth and have a dark oxide coating for superior performance and hook corrosion resistance. Stock sizes of double solitary sprockets range from ANSI #40 – #160 but additional sizes can be manufactured upon ask for. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets due to our quick reaction in-house machine shop. Something important to note is that even though these sprockets are double sprockets they will not double-strand roller chain. The charts below display the in-stock double one sprocket sizes and also have clickable links to the merchandise 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 nearly every manufacture utilizes four different types of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or simply “plate sprocket” is certainly a flat sprocket plate-wheel with no 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 known 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 attached to 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 operate two single-strands of roller chain aspect parallel to one another)
COMMON SPROCKET STYLES
QD style sprockets, also called “quick detachable” utilize a tapered bushing that’s bolted into the bore that is machined in the sprocket. When the bushing is certainly 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 design of interchangeable bushed sprockets that delivers a positive grasp on the driven shaft.
Shear Pin sprockets make use of a shear pin type hub that’s bolted to a sprocket to supply an overload device. If the torque ranking is exceeded the shear device 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 created first, then the hub style or code, and followed 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 quantity.
