Sprockets for double pitch roller chains can be found in a single or double-toothed design. Single-toothed sprockets for double pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the larger chain pitch of double pitch roller chains you’ll be able to increase strength by toothing modifications.
Double-toothed sprockets can be found either in full or in two tooth steps. Full tooth measures are double-toothed to ensure that only part of the the teeth is used effectively. The benefit is that whenever the chain is usually exchanged the up to now unutilised the teeth can be used after that, and the sprockets can remain in the system.
In order to increase the life cycle of a chain drive a lot more, sprockets can be produced with half 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 sort of toothing is often used when, due to the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless, and special materials 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 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 on hub and hole circle
Our sprockets for double 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 double pitch sprockets include standard roller and carrier roller design, single duty sprockets are made to purchase and typically take from a few business days to some weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets are 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 every other tooth because there are two the teeth per pitch. On odd tooth counts, any given tooth is engaged just on almost every other revolution which of training course escalates 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 build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are produced to where every single tooth gets engaged evenly on every revolution. This sprocket type is becoming obsolete generally in most applications but continues to be available.
When using double pitch roller chain it is highly recommended if not required to use a dual pitch sprocket. This is because double pitch sprockets are manufactured with a particular tooth profile that allows for the roller to properly seat and engage with the teeth of the sprocket. The above picture on the left is the regular tooth profile and the photo on the right may be the special dual pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be slightly deeper and cut differently to fully accept the dual pitch chain roller. If utilizing a standard sprocket, failure to engage will lead to chain jumping and also excessive wear. Something important to note is definitely that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is certainly 31 or even more you can use a standard roller chain sprocket. This rule does not apply to carrier roller style chains which where in fact the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
