Conveyor Chain Sprockets and Attachments Selection

Conveyor Chain Sprockets in Use

Conveyor chains are essential components in industrial settings, as they are responsible for the movement of materials and products. Among the different parts of conveyor chains, sprockets and attachments are integral to their operation. Choosing the right sprockets and attachments is crucial for the smooth and efficient functioning of conveyor chains. In this article, we will discuss the various factors to consider when selecting sprockets and attachments.

Factors to Consider When Selecting Conveyor Chain Sprockets

  • Sprocket Diameter
  • Number of Teeth
  • Tooth Profile
  • Hub Type
  • Material
  • Hardness
  • Bore Size
  • Keyway Size
  • Set Screw Type

Sprocket Diameter

The diameter of the sprocket is dependent on the required speed ratio, the size of the conveyor chain and the power transmission requirements. A larger sprocket diameter will help reduce the speed of the conveyor chain while a smaller sprocket diameter will increase the speed.

Number of Teeth

The number of teeth on the sprocket should be selected based on the pitch of the conveyor chain. A higher number of teeth will distribute the load across more contact points, leading to better wear resistance and longer life.

Tooth Profile

The tooth profile of the sprocket should match that of the conveyor chain. The common tooth profiles for conveyor chain sprockets are standard, deep link, and double-pitch.

Hub Type

The hub type of the sprocket should be selected based on the shaft size of the conveyor system. The most common hub types are Type A, B, C, D, E, F, and G.

Material

The material of the sprocket should be selected based on the operating conditions of the conveyor system. The most common materials used for conveyor chain sprockets are steel, cast iron, and plastic.

Hardness

The hardness of the sprocket should be selected based on the power transmission requirements of the conveyor system. A harder sprocket will be more wear-resistant but may produce more noise.

Bore Size

The bore size of the sprocket should be selected based on the shaft size of the conveyor system. The most common bore sizes for conveyor chain sprockets are 0.75 inches, 1 inch, 1.5 inches, and 2 inches.

Keyway Size

The keyway size of the sprocket should be selected based on the shaft size of the conveyor system. The most common keyway sizes for conveyor chain sprockets are 0.1875 inches, 0.25 inches, and 0.375 inches.

Set Screw Type

The set screw type of the sprocket should be selected based on the shaft size of the conveyor system. The most common set screw types for conveyor chain sprockets are cup point and flat point.

Factors to Consider When Selecting Conveyor Chain Attachments

  • Attachment Type
  • Attachment Pitch
  • Attachment Hole Size
  • Attachment Material
  • Attachment Surface Coating

Attachment Type

The attachment type of the conveyor chain should be selected based on the type of product being conveyed. The most common attachment types for conveyor chains are extended pin, bent, and straight.

Attachment Pitch

The attachment pitch of the conveyor chain should be selected based on the spacing between the products being conveyed. The most common attachment pitches for conveyor chains are every pitch, every other pitch, and every third pitch.

Attachment Hole Size

The attachment hole size of the conveyor chain should be selected based on the shaft size of the conveyor system. The most common attachment hole sizes for conveyor chains are 0.375 inches, 0.5 inches, and 0.625 inches.

Attachment Material

The attachment material of the conveyor chain should be selected based on the operating conditions of the conveyor system. The most common materials used for conveyor chain attachments are steel, cast iron, and plastic.

Attachment Surface Coating

The attachment surface coating of the conveyor chain should be selected based on the operating conditions of the conveyor system. The most common surface coatings used for conveyor chain attachments are zinc, nickel, and black oxide.

Conclusion

Conveyor chain sprockets and attachments are integral components of conveyor systems. Selecting the right sprockets and attachments is crucial for the smooth and efficient functioning of the conveyor system. When selecting conveyor chain sprockets and attachments, factors such as diameter, number of teeth, tooth profile, hub type, material, hardness, bore size, keyway size, attachment type, attachment pitch, attachment hole size, attachment material, and attachment surface coating should be considered.
