Sprockets for dual pitch roller chains are available in a single or double-toothed design. Single-toothed sprockets for dual pitch roller chains have the same behaviour as regular sprockets for roller chains in accordance 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 completely or in two tooth steps. Full tooth measures are double-toothed so that only part of the teeth is used effectively. The benefit is that whenever the chain is exchanged the so far unutilised teeth can be used after that, and the sprockets can stay in the system.
In order to boost 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 ahead in the meshing. This reduces the use of the chain and the tooth edges. This type of toothing is often used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are made from 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 area treated types.
Double pitch roller chains are produced according to the particular order and customers’ specifications.
On ask for 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 dual pitch roller chains can be found in a single or in a double-toothed version.
Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened metal with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller design, single duty sprockets are made to order and typically take from a couple of business days to a few 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 just build relationships the chain on almost 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 program 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
One duty sprockets are produced to where every tooth gets involved evenly on every revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using dual pitch roller chain it really is extremely recommended if not necessary to use a dual pitch sprocket. It is because double pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and engage with one’s teeth of the sprocket. The above photo 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 usually somewhat 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 important to note is that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or even more you can use a standard roller chain sprocket. This rule does not connect with carrier roller style chains which where the roller diameter exceeds the sidebar height, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
