Behind the part number 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 center letter for the hub designation is changed to represent so.
Standard Sprocket With Finished Bore Example:
Some manufactures may also designate in the component number if the sprocket is manufactured from a particular 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 areas.
Caliper Diameter – Because the bottom level diameter (BD) of a sprocket with odd number of teeth can’t be measured directly, caliper diameters will be the measurement across 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 as the sprocket revolves in mesh with the chain. PD= PITCH/ SIN(180/nT)
Outdoors Diameter (OD) The exterior diameter may be 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 length is not essential to proper meshing to with the chain. The outside diameter may vary based on the type of cutter used. OD=(pitch)(0.6+COT[180/nT])
Hub Diameter (H) – Is the distance across the hub in one side to some other. This diameter must not surpass the calculated diameter of the within of the chain sidebars.
Maximum Sprocket Bore – This dimension depends upon the required hub wall thickness for proper power. The dimensional allowance must be made for keyway and set screws.
Face Width (T) – Encounter width is bound in its maximum dimension to allow 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 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 teach sprockets, and replacing them can cost lots of time and cash. Additionally, the functionality of a conveyor or drive depends upon sprocket-chain interaction. Using the right sprocket is just as important as choosing the right chain. At Ever-power Roller Chain, we offer a wide selection of standard roller chain sprockets at unbeatable prices. Our sprockets are manufactured to perform well under pressure and so are long lasting. The roller chain sprockets accessible in our store include single-strand roller chain sprockets, double strand sprockets and multi-strand roller chain sprockets. Furthermore, our drive chain sprockets fulfill both ANSI and ASME standards.
We’re positive you’ll become happy when you buy industrial chain sprockets inside our store, because they’ll last you a long time. If you’re not sure what sprockets will be the ones you need for your machine, please don’t hesitate to give us a contact. Our knowledgeable staff, superior products, and unbeatable prices are the known 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 one strand roller chain sprockets are manufactured with hardened tooth (for tooth counts under 30), used high quality quality SAE 1045 steel material, and are finished with black-oxide for corrosion level of resistance.
To start shopping simply choose what chain size you are using with your sprocket. Following choose the type needed, finally select the desired tooth count and possible accessories needed, then you are ready to obtain your sprockets! If at any stage you have questions or trouble finding or picking your sprocket please get in touch with our customer support department and we will be happy to help you.
DOUBLE SINGLE SPROCKETS
Double single sprockets are created to operate two single-strand type roller chains, this is where the name “dual single” originated from. Typically these sprockets certainly are a design but both BTB taper bushed and QD style is available from stock. Our double solitary sprockets are produced with hardened teeth and have a black oxide coating for superior performance and hook corrosion resistance. Share sizes of double solitary sprockets range between ANSI #40 – #160 but additional sizes can be manufactured upon request. We are able to also supply quick reaction custom re-bores and MTO specialty double single sprockets due to our quick reaction in-house machine store. Something vital that you 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 double solitary sprocket sizes and have clickable links to the product pages themselves.
ROLLER CHAIN SPROCKET NOMENCLATURE
Different sprocket manufactures use different “terms” or nomenclature to spell it out their sprockets. Though, throughout the general history of roller chain sprockets nearly every manufacture utilizes four various kinds of sprockets and has used the same nomenclature for them.
STANDARD SPROCKET STYLES
Style A, also referred to as A-Plate or just “plate sprocket” is usually a set sprocket plate-wheel with no 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 called 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 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 standard styles as well as various other styles upon request.
D – Dual Roller Chain Sprockets/ Duplex Sprockets
E – Triple Roller Chain Sprockets/ Triplex Sprockets
F – Four 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 design sprockets, also referred to as “quick detachable” use a tapered bushing that’s bolted in to the bore that is machined in the sprocket. When the bushing is definitely inserted in to the sprocket is certainly 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 make use of a shear pin type hub that is bolted to a sprocket to provide an overload gadget. If the torque ranking is exceeded the shear gadget disengages the sprocket from the drive.
Split type roller chain sprockets are produced for quick installation without disruption of the shaft and alignment.
SPROCKET PART NUMBER NOMENCLATURE
When identifying a sprocket with a part amount, standardly the chain pitch will be created first, then the hub style or code, and accompanied by the number of teeth the sprocket has. If the sprocket is usually multi strand there will frequently be a letter prefix at the start of the part quantity.
