How to use the drive chain roller chain

The drive chain roller chain is mainly composed of rollers, pins, sleeves, inner chain plates, outer chain plates, cotter pins, and connecting pins. The materials used should be confirmed to have sufficient strength and performance under the condition of good teeth. The tooth surface is mostly heat treated. The material of small sprocket is better than that of large sprocket, and the tooth surface hardness is higher, because during operation, the teeth of small sprocket mesh more times than that of large sprocket, Its wear and impact are also serious

Among the basic parameters of roller chain and sprocket engagement, the main parameter of roller chain is pitch. When the pitch is increased, the size of parts in each chain will also increase correspondingly, and the power transmitted will also increase accordingly. However, when the number of sprocket teeth is determined, the larger the pitch wheel diameter will be, in order to make the diameter not too large, when the load is large, It is appropriate to use double-row chain or multi-row chain with pitch

When the roller chain is in use, the head and tail are connected to form a ring. When the number of chain links is even (even), the joint can be overlapped by the inner or outer chain plates, and the cotter pin or spring clip can be inserted and locked. When the number of chain links is odd (odd), it is necessary to use a transition chain link head and tail to connect. When the chain is under tension, the transition chain link will have additional bending moment. Therefore, The chain with even (even) links is more suitable

Warm prompt:

The carrying capacity of a multi-row chain is basically proportional to the number of rows. The more the number of rows, the higher the carrying capacity will be. However, due to some errors in manufacturing and installation, the load of each row will be difficult to be uniform, and the more the number of rows, the more uneven the number of rows will be. Therefore, it is not appropriate to have too many rows. It is better to have fewer than four rows
