Sprockets for double pitch roller chains can be found in a single or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Due to the bigger chain pitch of double pitch roller chains it is possible to increase durability by toothing modifications.
Double-toothed sprockets are offered either completely or in two tooth steps. Full tooth steps are double-toothed so that only part of the tooth is used effectively. The advantage is that when the chain is certainly exchanged the up to now 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 produced with fifty percent tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This decreases 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 could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless, 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.
Double pitch roller chains are produced according to the particular 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 upon pitch circle
Slot holes upon 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 double 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 produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, single duty sprockets are made to order 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 outside diameter and width as the single-pitch equivalent just with a different tooth profile to permit correct 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 provided tooth is engaged just on almost every other revolution which of program 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 could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are produced to where every tooth gets involved evenly on each revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using double pitch roller chain it really is extremely recommended if not required to use a double pitch sprocket. The reason being dual pitch sprockets are produced with a particular 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 regular tooth profile and the picture on the right is the special dual pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is slightly deeper and cut differently to fully accept the double pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping along with excessive wear. Something vital that you note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or more you can make use of a standard 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 consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
