Conveyor sprockets

Heat treatment method of sprocket

  1. Medium carbon steel and medium carbon alloy steel are usually used for surface hardening. After surface hardening, the hardness of tooth surface is generally 40-55HRC. It has the characteristics of anti fatigue pitting, strong adhesion resistance and good wear resistance. As the bare core will eventually harden, the sprocket still has enough toughness to withstand small impact loads.
  2. Carburizing and quenching are often used for low carbon steel and low carbon total steel. After carburizing and quenching, the hardness of tooth surface can reach 56-62 hrc, while the toughness of tooth center is still high. After carburizing and hardening, the gear teeth will deform. Great running in should be carried out.
  3. Nitriding is a kind of surface chemical heat treatment. No other heat treatment is needed after nitriding, and the hardness of tooth surface can reach 700~900 hv. As nitrided gears are characterized by high hardness, low processing temperature and small deformation, they are suitable for difficult grinding of gears and are commonly used in nitrided steels containing chromium, copper, lead and other alloy elements.
  4. Medium carbon steel and medium carbon alloy steel are generally quenched and tempered, and the hardness of gear surface after quenching and tempering is 220 × 280 HBS。 Due to low hardness, gear can be trimmed after heat treatment.
  5. Normalizing can eliminate internal stress, refine grains, and improve mechanical and cutting properties. Gears with low mechanical strength requirements can be standardized with medium carbon steel, and large diameter gears can be standardized with cast steel.

Conveyor sprockets are toothed wheels designed to engage with a conveyor chain and drive it along a conveyor system. They are used in many industrial processes, such as in production lines, material handling systems, and packaging applications, to move products and materials from one location to another.

Conveyor sprockets come in a variety of sizes and shapes, depending on the specific conveyor application. They are typically made from high-quality materials, such as steel, to withstand the high stresses and wear associated with the conveyor system. The teeth on the sprockets are also hardened to resist wear and prevent premature failure.

One of the main factors in selecting conveyor sprockets is the pitch of the conveyor chain. The pitch refers to the distance between the rollers on the chain and determines the size of the sprocket teeth needed to properly engage with the chain. Other considerations include the number of teeth on the sprocket, which affects the speed of the chain, and the bore diameter, which must match the size of the shaft used to mount the sprocket.

Conveyor sprockets can also have additional features such as keyways, set screws, or a hub for welding to accommodate specific drive configurations. Some sprockets may even have special coatings or finishes to increase their durability or resistance to certain chemicals or environments.

Overall, conveyor sprockets play a crucial role in the reliable and efficient operation of conveyor systems. Proper selection and maintenance of conveyor sprockets can help ensure optimal system performance and long service life.
