Sprockets for dual 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 bigger chain pitch of double pitch roller chains it is possible to increase sturdiness by toothing modifications.
Double-toothed sprockets can be found either completely or in two tooth steps. Full tooth methods are double-toothed so that only a part of the tooth is used effectively. The benefit is that whenever the chain is exchanged the so far unutilised teeth can be used then, and the sprockets can remain 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 forward in the meshing. This decreases the wear of the chain and the tooth edges. This kind of toothing is often used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless, and special materials with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
Dual pitch roller chains are manufactured according to the respective order and customers’ specifications.
On request we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore on 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 regular roller and carrier roller style, single duty sprockets are made to purchase and typically take from a couple of business days to a few weeks to manufacture based upon our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow proper seating of the chain. On even tooth-counts, these sprockets only engage with 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 almost every other revolution which of training course increases the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to allow the carrier roller to properly chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Solitary duty sprockets are manufactured to where every single tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete in most applications but is still available.
When using double pitch roller chain it is extremely recommended if not necessary to use a double pitch sprocket. It is because dual pitch sprockets are manufactured with a particular tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above photo on the left is the regular tooth profile and the photo on the right is the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile can be somewhat deeper and cut differently to totally accept the double pitch chain roller. If using a standard sprocket, failing to engage will lead to chain jumping in addition to 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 definitely 31 or even more you can use a typical roller chain sprocket. This guideline does not apply to carrier roller design chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
