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 can be changed to represent so.
Regular 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 could be placed in leading of the part amount 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 areas.
Caliper Diameter – Because the bottom diameter (BD) of a sprocket with odd amount of teeth cannot be measured directly, caliper diameters will be the measurement over the tooth spaces nearly opposite.
Pitch Diameter (PD) – The diameter across to the pitch circle which may be the circle accompanied 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 may be the measurement from the end of the sprocket tooth across to the corresponding point directly over the sprocket. It is comparatively unimportant as the tooth duration is not vital to appropriate 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) – Is the distance across the hub in 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 designed for keyway and set screws.
Face Width (T) – Face width is limited in its maximum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimal width is limited to provide the correct strength to transport the imposed loads.
Length Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough important to withstand the torque transmitted by the shaft. This also procedures 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 train sprockets, and replacing them can cost considerable time and money. Additionally, the overall performance of a conveyor or drive depends upon sprocket-chain conversation. Using the right sprocket is simply as important as deciding on the best chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are designed to perform well under pressure and so are long lasting. The roller chain sprockets accessible in our shop include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet up with both ANSI and ASME standards.
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 uncertain what sprockets are the ones you need for your machine, make sure you don’t hesitate to provide us a call. Our knowledgeable staff, excellent products, and unbeatable prices will be the reasons for our A+ BBB ranking!
Solitary 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 regular one strand roller chain sprockets are produced with hardened teeth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Following select the type needed, lastly select the desired tooth count and possible accessories needed, then you are ready to get your sprockets! If at any stage you have questions or difficulty finding or selecting your sprocket please contact our customer service department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary 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 solitary sprockets are produced 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 could be manufactured upon ask for. We are able to also supply quick reaction custom re-bores and MTO specialized double single sprockets due to our quick response in-house machine store. Something important to note is that despite the fact that these sprockets are dual sprockets they’ll not double-strand roller chain. The charts below display the in-stock double single sprocket sizes and also have clickable links to the merchandise pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use 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 used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also called A-Plate or simply “plate sprocket” is usually a set 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 using one side.
Style C, also called C-Hub sprockets is definitely 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 along with several other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
Electronic – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four Strand Sprockets/ Quadruple Sprockets
DS – Double One (these sprockets are created to operate two single-strands of roller chain part parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also referred to as “quick detachable” make use of a tapered bushing that is bolted in to the bore that is machined in the sprocket. When the bushing can be inserted into 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 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 gadget. If the torque rating 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 number, standardly the chain pitch will be written first, then the hub design or code, and followed 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 beginning of the part quantity.
