Hollow Pin Conveyor Chains for Transmission are a type of integrated transmission and conveying chain featuring hollow pins as their core characteristic. They combine the functions of power transmission and material conveying. The design of the hollow pins not only facilitates the installation of accessories but also allows adaptation to shaft - type transmission components. They are widely used in industrial scenarios that require the simultaneous realization of transmission and conveying.
Working Principle
Hollow pin conveyor chains for transmission drive the chain body to move through the rotation of the sprocket, realizing the transmission of power from the driving end to the driven end. At the same time, the accessories installed on the hollow pins are used to contact materials, completing the conveying, positioning or sorting of materials during the transmission process. Due to the structural characteristics of the hollow pins, the installation positions of the accessories can be flexibly adjusted, and multi - chain linkage can be achieved through the insertion of shafts, ensuring the synchronization of conveying at multiple stations (for example, in automatic assembly lines, multiple sets of chains run at the same speed through the same inserted shaft, ensuring accurate docking of workpieces between various stations).
Material Selection
- Carbon steel: After surface treatment such as galvanizing, painting or blackening, it is suitable for transmission and conveying in general industrial environments. It has low cost and strong load - bearing capacity, and is suitable for heavy - duty scenarios (such as the conveying of machine tool accessories and the transfer of hardware parts).
- Stainless steel (304/316): It has excellent corrosion resistance and rust resistance, and is suitable for humid environments or environments with corrosive media such as food processing, pharmaceutical production and chemical industry. It can directly contact materials without causing pollution.
- High - strength alloy: Aiming at the transmission requirements of high load and high speed, alloy steel is used and subjected to special heat treatment to improve the wear resistance and fatigue resistance of pins and chain plates, and prolong the service life (such as the auxiliary conveying system of heavy machinery).
