Sprockets for double pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for double pitch roller chains possess the same behaviour as regular sprockets for roller chains according to ISO 606. Because of the bigger chain pitch of dual pitch roller chains it is possible 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 a part of the teeth is used effectively. The benefit is that when the chain is usually exchanged the up to now unutilised tooth 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 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, just minor deflections can be realised.
Our sprockets and plate sprockets are made from C 45, stainless steel, and special components with a material strength 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 particular 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 on 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 black oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller style, one duty sprockets are created to purchase and typically take from a few 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 outside diameter and width as the single-pitch equivalent simply with a different tooth profile to permit proper seating of the chain. On also tooth-counts, these sprockets just build relationships the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any provided tooth is engaged only on every other revolution which of training course increases 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 engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are manufactured to where every single tooth gets engaged evenly on every revolution. This sprocket type has become obsolete in most applications but is still available.
When using double pitch roller chain it really is extremely recommended if not required 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 correctly seat and engage with the teeth of the sprocket. The above picture on the left is the regular 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 certainly somewhat 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 in addition to excessive wear. Something vital that you note is usually that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is certainly 31 or more you can use a standard roller chain sprocket. This guideline 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.
