In the contact area of the Multi-Segment Sprocket teeth with the chain due to the presence of friction (rolling and sliding), there is a wear phenomenon, so this area needs high wear resistance, on the other hand, the driving set endures a lot of torque and stress during rotation. and requires high toughness and strength.
In this system, the contact area is designed in several pieces and can be installed for the assembly to increase the life of the assembly while maintaining strength, toughness and wear resistance.
