The development of conveyor chain structure has different requirements for conveyor chains, transmission chains, and traction chains. The functions that conveyor chains need to meet are: carrying transported items, meshing with drive sprockets, running on supporting tracks, and minimal chain wear and elongation.

　　The development of conveyor chains and chain conveyors is complementary. It is necessary for professionals engaged in the design and application of chain conveyors to understand the development of chains used in conveyors.

　　1. The development of chain structures can realize the functions of chain conveyors in various ways, thereby promoting the development of conveyor chain structures. These methods include:

　　The way of carrying and transporting goods

　　a. Chain plate bearing capacity; b、 Chain roller bearing.

　　2. The way it operates on orbit

　　a. The chain plate slides on the track; b、 The chain roller rolls on the track; c、 The chain attachment rolls on the track.

　　3. The meshing method between the chain and the drive sprocket

　　a. The chain plate meshes with the sprocket teeth; b、 The roller (or sleeve) meshes with the sprocket teeth.
