Basic Structure of Sprockets

Sprockets are essential components in mechanical systems, featuring a wheel with teeth that interlock with a chain or track. The fundamental structure of a sprocket comprises two main parts: the hub, which is the central section, and the teeth, which are the external projections that engage with the chain. The hub may incorporate a bore suitable for shaft mounting, and sometimes a keyway that allows for the insertion of a key to securely fasten the sprocket to the shaft. When designing a custom sprocket, crucial parameters must be specified, including:

  • Material
  • Tooth Profile
  • Number of Teeth
  • Dimensions
  • Bore Size
  • Keyway
  • Surface Treatment

These parameters significantly influence the sprocket's performance, including its durability, strength, and resistance to wear, ensuring that it meets the specific demands of its application.

Material and Manufacturing Process

The NK40B Plain Bore Sprocket is manufactured from premium-quality carbon steel, alloy steel, or stainless steel. The selection of material is critical, as it affects the sprocket's strength, durability, and wear resistance. The manufacturing process is thorough and includes several stages: material selection, cutting, stamping, forging, machining, heat treatment, surface hardening, and surface treatment, followed by rust pre
