Double-toothed sprockets can be found either in full or in two tooth steps. Complete tooth methods are double-toothed so that only a part of the teeth is used effectively. The advantage is that when the chain can be exchanged the so far unutilised tooth can be used after that, and the sprockets can stay 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 decreases the wear of the chain and the tooth edges. This sort of toothing is frequently used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are constructed with C 45, planetary gearbox stainless, and special components with a material strength of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface treated types.
Double pitch roller chains are manufactured according to the respective order and customers’ specifications.
On request we supply sprockets with:
