Sprockets for double pitch roller chains are available in an individual or double-toothed design. Single-toothed sprockets for double pitch roller chains have the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the larger chain pitch of dual pitch roller chains you’ll be able to increase sturdiness by toothing modifications.
Double-toothed sprockets are offered either in full or in two tooth steps. Complete tooth techniques are double-toothed to ensure that only part of the tooth is used effectively. The advantage is that whenever the chain is exchanged the so far unutilised tooth can be used after that, and the sprockets can stay in the system.
In order to raise the life cycle of a chain drive a lot more, sprockets can be manufactured with half tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the use of the chain and the tooth edges. This sort of toothing is often used when, because of the respective design, just minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless, and special components with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface area treated types.
Double pitch roller chains are manufactured according to the particular order and customers’ specifications.
On ask for we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore upon pitch circle
Slot holes upon hub and hole circle
Our sprockets for dual pitch roller chains are available in an individual or in a double-toothed version.
Our in-stock standard dual pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller design, one duty sprockets are made to order and typically take anywhere from a couple of business days to some weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets will be the same outside diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On actually tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged only on every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to allow the carrier roller to properly chair and build relationships each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Solitary duty sprockets are produced to where every single tooth gets engaged evenly on every revolution. This sprocket type has become obsolete in most applications but continues to be available.
When using double pitch roller chain it really is extremely recommended if not necessary to use a double pitch sprocket. It is because dual pitch sprockets are produced with a special tooth profile that allows for the roller to properly seat and build relationships the teeth of the sprocket. The above photo on the left is the standard tooth profile and the picture on the right may be the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be somewhat deeper and cut differently to fully accept the double pitch chain roller. If utilizing a standard sprocket, failure to engage will result in chain jumping along with excessive wear. Something important to note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or more you can use a standard roller chain sprocket. This guideline does not connect with carrier roller design chains which where in fact the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
