Double Pitch Chain Sprockets

Sprockets for dual pitch roller chains are available in an individual or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Due to the larger chain pitch of double pitch roller chains it is possible to increase toughness by toothing modifications.

Double-toothed sprockets can be found either completely or in two tooth steps. Full tooth actions are double-toothed so that only part of the tooth is used effectively. The benefit is that whenever the chain is definitely exchanged the up to now unutilised the teeth can be used after that, and the sprockets can remain in the system.
In order to raise the life cycle of a chain drive even more, sprockets can be manufactured with fifty percent tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the use of the chain and the tooth edges. This kind of toothing is frequently used when, due to the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless, and special components with a material power of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface treated types.
Dual pitch roller chains are produced according to the respective order and customers’ specifications.
On demand 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 can be found in an individual or in a double-toothed version.

Our in-stock standard dual pitch sprockets are produced out of SAE-1045 case hardened metal with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller style, single duty sprockets are created 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
Regular roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On also tooth-counts, these sprockets just engage with the chain on almost every other tooth because there are two teeth per pitch. On odd tooth counts, any given tooth is engaged just on almost every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to permit the carrier roller to properly seat and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are produced to where every single tooth gets involved evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but is still available.
When using dual pitch roller chain it is extremely recommended if not necessary to use a dual pitch sprocket. The reason being double pitch sprockets are produced with a particular tooth profile that allows for the roller to properly seat and build relationships one’s 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 dual pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is definitely somewhat deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will lead to chain jumping along with excessive wear. Something vital that you note is definitely that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or even 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.
