Behind the part amount a suffix of “H” is added if the 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 changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures will also designate in the component amount if the sprocket is produced from a special material. This designation can be placed in the front of the part quantity or behind, if it is 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 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 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 is the measurement from the end 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 correct meshing to with the chain. The outside diameter may vary based on the kind of cutter utilized. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance across the hub from one side to some other. 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 strength. The dimensional allowance should be designed for keyway and established screws.
Face Width (T) – Encounter width is limited in its optimum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the proper strength to carry the imposed loads.
Duration Thru Bore (L) – The length thru bore must be sufficient to allow a long 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 may bring your machinery to a grinding halt. Many machines can’t operate without their drive train sprockets, and changing them can cost lots of time and money. Additionally, the functionality of a conveyor or drive depends on sprocket-chain interaction. Using the proper sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we provide a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are engineered to execute well under pressure and so are long lasting. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet both ANSI and ASME requirements.
We’re positive you’ll end up being happy when you buy industrial chain sprockets inside our store, because they’ll last you quite a long time. If you’re uncertain what sprockets will be the ones you will need for your machine, make sure you don’t hesitate to provide us a contact. Our knowledgeable staff, superior products, and unbeatable prices will be the known reasons for our A+ BBB ranking!
SINGLE STRAND ROLLER CHAIN SPROCKETS
There are six different standard varieties of sprockets for single strand roller chain. We stock a complete type of each type! Our standard solitary strand roller chain sprockets are produced with hardened teeth (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 out shopping simply choose what chain size you are employing with your sprocket. Next choose the type needed, finally select the preferred tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any stage you have queries or problems 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 solitary sprockets are created to operate two single-strand type roller chains, that’s where the name “dual single” came from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from stock. 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 one sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon ask for. We are able to also supply quick response custom re-bores and MTO specialized double single sprockets because of our quick response in-house machine shop. Something important to note is that even though these sprockets are double sprockets they’ll not double-strand roller chain. The charts below display the in-stock double single sprocket sizes and have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “terms” or nomenclature to describe their sprockets. Though, through the entire 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 referred to as A-Plate or just “plate sprocket” is certainly a flat sprocket plate-wheel without hubs that extrude upon either side.
Style B, also referred to as B-Hub sprockets is a sprocket with a hub that extrudes on 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 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 standard styles in addition to several other styles upon request.
D – Double 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 side parallel to each other)
COMMON SPROCKET STYLES
QD design sprockets, also referred to as “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 is definitely 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 
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 accompanied by the number of the teeth the sprocket has. If the sprocket is certainly multi strand there will frequently be a letter prefix at the start of the part number.
