Behind the part quantity a suffix of “H” is added if the teeth are hardened from being heat-treated. If the sprocket is definitely a QD or taper bushed design the guts letter for the hub designation is definitely 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 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 areas.
Caliper Diameter – Since the bottom level diameter (BD) of a sprocket with odd amount 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 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 exterior diameter is the measurement from the tip of the sprocket tooth across to the corresponding stage directly across the sprocket. It is comparatively unimportant as the tooth size is not vital to proper meshing to with the chain. The outside diameter may vary based on the kind of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub from one side to some other. This diameter must not go beyond the calculated diameter of the inside of the chain sidebars.
Optimum Sprocket Bore – This dimension is determined by the required hub wall thickness for proper strength. The dimensional allowance should be made for keyway and established screws.
Face Width (T) – Face width is bound in its optimum dimension to permit proper clearance to supply for chain engagement and disengagement. The minimum width is limited to provide the correct strength to transport the imposed loads.
Duration Thru Bore (L) – The length thru bore must be sufficient to allow an extended enough essential to withstand the torque transmitted by the shaft. This also steps the balance 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 teach sprockets, and replacing them can cost lots of time and money. Additionally, the overall performance of a conveyor or drive depends on sprocket-chain interaction. Using the right sprocket is just as important as selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are designed to perform well under pressure and are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets meet up with both ANSI and ASME requirements.
We’re positive you’ll be happy when you get industrial chain sprockets in our store, because they’ll last you quite a long time. If you’re uncertain what sprockets are the ones you need for your machine, please don’t hesitate to give us a contact. Our knowledgeable staff, excellent products, and unbeatable prices will be the reasons for our A+ BBB ranking!
SINGLE 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 produced with hardened tooth (for tooth counts under 30), used premium quality SAE 1045 metal material, and are completed with black-oxide for corrosion resistance.
To start out shopping simply select what chain size you are using with your sprocket. Following choose the type needed, finally select the desired tooth count and feasible accessories needed, then you are ready to obtain your sprockets! If at any point you have queries or difficulty finding or picking your sprocket please contact our customer service department and we’ll be happy to help you.
DOUBLE SINGLE SPROCKETS
Double one sprockets are made to operate two single-strand type roller chains, this is where the name “double single” came from. Typically these sprockets are A design but both BTB taper bushed and QD style is available from share. Our double solitary sprockets are produced with hardened tooth and have a black oxide coating for excellent performance and a slight corrosion resistance. Share sizes of double one sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon demand. We are able to also supply quick response custom re-bores and MTO specialty double single sprockets due to our quick response in-house machine shop. Something important to note is that despite the fact that these sprockets are double sprockets they will not double-strand roller chain. The charts below display 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 spell it out their sprockets. Though, through the entire general background of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has adopted the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also known as A-Plate or simply “plate sprocket” is definitely a set sprocket plate-wheel without hubs that extrude on either side.
Style B, also known as B-Hub sprockets is a sprocket with a hub that extrudes on 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 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 and also various other styles upon request.
D – Dual 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” use a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is certainly inserted into the sprocket can be compresses onto the shaft, which provides a tight grip.
Taper Bushed sprockets, commonly designated with TL, BTL, CTL, TB, BTB, or CTB is another style of interchangeable bushed sprockets that delivers a positive grasp 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 can be exceeded the shear device disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation with out disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part quantity, standardly the chain pitch will be written first, then the hub design or code, and accompanied by the number of the teeth the sprocket has. If the sprocket can be multi strand there will most often be considered a letter prefix at the beginning of the part amount.
