The conveyor chain is mainly used for conveying goods and materials. Compared with the transmission chain, it has a slower chain speed and a larger load capacity. Therefore, it is hoped that it has the following performance characteristics:

1.Lightweight yet strong, the weight of a conveyor chain is usually proportional to the load it can bear. Overloaded chains will increase the tension inside the chain, limiting the conveying capacity and making it uneconomical;

2Good wear resistance, when the conveyor chain is working, the number of sprocket teeth is generally small, the relative bending angle between the chain links is large, and the chain wears and elongates quickly, which limits its service life;

3The resistance to sliding or rolling should be small. Conveyor chains often slide on tracks or roll forward with roller support, resulting in low resistance to sliding or rolling and improving efficiency and lifespan;

4Strong impact resistance, conveyors with uneven loads or high-speed operation can generate impact loads in many cases. The conveyor chain should have strong and resilient impact resistance

5Good resistance to wear, corrosion, high temperature, and other special environments

6Good reliability and maintainability

Therefore, when designing a conveyor chain, the structure should be reasonable, and the material suspension should be appropriate to ensure the functionality of the conveyor chainAnd service life

IIStandard Features and User Application Guidelines

1The accessories for conveying precision roller chains with short pitch transmission are mainly installed inAA series of chains, from which a conveyor chain is derived, with a pitch of12.7-50.8The chain plate is in an "eight" shape. The chain is supported by rollers on the track, and due to the small diameter of the rollers, their load-bearing capacity and transmission efficiency are not as good as large rollers. Therefore, it is only suitable for small conveyors with light loads and short conveying distances. But its conveying speed can be high, the accuracy of the conveying rhythm is good, and the overall structure is relatively compact.

2Double pitch precision roller chains and sprockets for transmission and conveying are suitable for general mechanical transmission or conveying, with a pitch of25.4-76.2mmDouble pitch precision roller chain is a lightweight chain derived from doubling the pitch specified by the precision roller chain for short pitch transmission. As a conveyor chain, it has three structural characteristics compared to a transmission chain:（1）Come and take it, it's not a qualitative change8字形(2)The end of the chain plate is fan-shaped, not semi-circular（3）The rollers have enlarged large roller groups, which have high load-bearing capacity and transmission efficiency.

3Conveyor accessories and sprockets are currently the only metric chain standards in the national standard, suitable for conveyor chains used in transportation and mechanical loading and unloading. The characteristics are:（1）The pitch increases to an integer, and the minimum is40mmThe maximum is1000mm（2）Pin shafts are divided into hollow pin shafts and solid pin shafts, and roller types are divided into non roller, small roller, edged roller, and non edged large roller. Basic chain forms include chains with the same strength value but multiple different pitches（3）The chain plate of the standard chain is a straight edge chain plate with a fan-shaped end, and the height of the inner and outer chain plates is equal. The minimum gap between the pin shaft and the sleeve（0.1-0.2mm）Multiple for precision roller chains（4）The minimum gap between the inner and outer chain links increases with the increase of strength value. This loose gap can make the hinge less likely to be blocked by debris when the environment is harsh（5）The requirement for chain length accuracy is lower than that of roller chains and sleeve chains used for transmission
