Behind the part amount a suffix of “H” is added if one’s teeth are hardened from being heat-treated. If the sprocket is a QD or taper bushed design the center letter for the hub designation is certainly changed to represent so.
Regular Sprocket With Finished Bore Example:
Some manufactures may also designate in the part number if the sprocket is produced from a special material. This designation can be placed in leading of the part number 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 level 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 is the circle accompanied by the centers of the chain pins as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outside Diameter (OD) The outside diameter is the measurement from the end of the sprocket tooth across to the corresponding point directly across the sprocket. It really is comparatively unimportant as the tooth length is not essential to appropriate meshing to with the chain. The exterior diameter may vary based on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – May be the distance over the hub in one side to another. This diameter should never surpass 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 limited in its maximum dimension to allow proper clearance to supply for chain engagement and disengagement. The minimum width is bound to provide the proper strength to transport the imposed loads.
Length 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 measures 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 train sprockets, and changing 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 selecting the most appropriate chain. At Ever-power Roller Chain, we offer a wide selection of regular roller chain sprockets at unbeatable prices. Our sprockets are engineered to perform well under pressure and so are long lasting. The roller chain sprockets for sale in our store include single-strand roller chain sprockets, dual strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME requirements.
We’re positive you’ll be happy when you get industrial chain sprockets inside our shop, because they’ll last you a long time. If you’re uncertain what sprockets will be the ones you will need for your machine, please don’t hesitate to give us a call. Our knowledgeable staff, excellent items, and unbeatable prices are the reasons for our A+ BBB rating!
One STRAND ROLLER CHAIN SPROCKETS
There are six different standard styles of sprockets for single strand roller chain. We stock a complete type of each type! Our standard single strand roller chain sprockets are produced with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 metal material, and are completed with black-oxide for corrosion level of resistance.
To start shopping simply select what chain size you are using with your sprocket. Following select the type needed, lastly select the preferred tooth count and feasible accessories needed, you then are ready to obtain your sprockets! If at any stage you have questions or trouble finding or choosing your sprocket please contact our customer support department and we’ll be happy to assist you.
DOUBLE SINGLE SPROCKETS
Double solitary sprockets are created to run two single-strand type roller chains, this is where the name “dual single” came from. Typically these sprockets are A design but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are manufactured with hardened tooth and have a black oxide coating for superior performance and hook corrosion resistance. Stock sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes could be manufactured upon demand. We can also supply quick response custom re-bores and MTO specialty double single sprockets because of our quick response in-house machine shop. Something important to note is that despite the fact that these sprockets are double sprockets they’ll not double-strand roller chain. The charts below show the in-stock dual solitary sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures make use of different “terms” or nomenclature to describe their sprockets. Though, throughout the general history of roller chain sprockets nearly every produce utilizes four various kinds of sprockets and has followed 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 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 referred to as 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 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 standard styles in addition to many 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 Single (these sprockets are made to operate two single-strands of roller chain side parallel to each other)
COMMON SPROCKET STYLES
QD style sprockets, also known as “quick detachable” utilize a tapered bushing that is 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 design 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 provide an overload device. If the torque rating is usually exceeded the shear device 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 part number, standardly the chain pitch will be written first, then the hub design or code, and accompanied by the number of tooth the sprocket has. If the sprocket is definitely multi strand there will most often be a letter prefix at the start of the part amount.
