Product Description

Tooth chain, also known as silent chain, belongs to a form of transmission chain. Tooth chain is an important mechanical basic component widely used. It is mainly used in high speed, heavy load, low noise and large center distance. Its transmission performance is better than that of tooth belt drive, gear drive and claw chain drive. It has become 1 of the preferred pair transmission forms in many industries. In meshing form, it can be divided into internal meshing tooth chain. External meshing tooth chain and internal and external compound meshing tooth chain, in which the internal and external compound meshing tooth chain has the least noise and the most extensive application.

application area
Tooth chain is an important mechanical foundation widely used. Especially at high speed, heavy load, low noise and large center distance, its transmission performance is better than that of tooth belt transmission, gear transmission and roller chain transmission. It has become 1 of the preferred transmission forms in many industries. In recent years, automotive engines (timing drive, oil pump, common rail pump, high-pressure pump, balance shaft, etc.), transmission, transmission box, motorcycle, forklift, steam turbine, aircraft, ship, rolling machinery, machine tools, industrial pumps, and other high-speed transmission, have been more and more widely used in various forms of tooth chains. With the continuous development of high-speed chain transmission technology, a new series of high-speed gear chain products with different structural forms and meshing mechanisms adapted to the “personalized” needs of the mainframe have been introduced in developed countries and entered the domestic market.

Characteristics of toothed chain
Because the tooth chain itself has some characteristics. In recent years, the engine of automobile, motorcycle and forklift has been more and more widely used. Its several prominent features are:
(1) the noise is very small. Tooth chain is meshed by involute tooth profile of working chain plate and sprocket teeth. Therefore, the meshing noise is smaller than that of roller chain and sleeve chain.
(2) High reliability. This is because the chain segment of the tooth chain is a multi-chip structure. When individual chains are destroyed in the work, the whole chain is not immediately disconnected, which enables people to find and replace in time. At the same time. Compared with the sleeve chain and roller chain with the same pitch, the gear chain drive is more compact. To increase the load-carrying capacity, the gear chain drive only needs to increase the smaller size in the width direction, while the sleeve chain drive needs to increase the pitch of the chain or adopt multi-row chains.
(3) The motion accuracy is high. This is because in the straight plate roller chain, because of the wear and tear of the hinge, the actual pitch of the inner and outer joints is gradually different, and the pitch of the outer joints becomes larger and larger, which reduces the transmission accuracy. The elongation of each link of the tooth chain is uniform due to wear, so it keeps a high motion accuracy.

Identifying Signs of Wear and Fatigue in a Toothed Chain and Preventive Actions

Regular inspection of a toothed chain is essential to identify signs of wear and fatigue, which can help prevent unexpected failures. Here’s how to spot these signs and take appropriate action:

  • 1. Elongation: Measure the distance between several chain pins over a specific length. If the chain has elongated beyond its allowable limits, it indicates wear. Excessive elongation can lead to poor engagement with the sprockets and cause jumping or skipping.
  • 2. Plate Wear: Inspect the plates and rollers for signs of wear, such as flat spots or significant rounding. Worn plates can lead to uneven stress distribution and reduced performance.
  • 3. Roller Wear: Check the roller diameter and shape. If the rollers are significantly worn or have a flat appearance, it indicates fatigue and wear. Worn rollers can result in poor sprocket engagement and increased friction.
  • 4. Side Plate Wear: Inspect the side plates for any signs of wear or elongation of the holes. Worn side plates can lead to chain misalignment and reduced efficiency.
  • 5. Chain Stretch: A stretched chain will no longer fit tightly around the sprockets. If you notice a loose chain that has lost its tension, it may be due to wear and stretching.
  • 6. Visible Cracks or Damage: Look for any visible cracks, breaks, or damage to the chain components. Cracked or damaged parts can cause catastrophic failure under load.
  • 7. Excessive Noise or Vibration: Unusual noise or vibration during chain operation can be an indication of wear or misalignment. Investigate the source of the noise and take appropriate action.
  • 8. Wear Limit Indicators: Some chains have wear limit indicators that show when the chain has reached its maximum allowable wear. These indicators can help you determine when it’s time to replace the chain.

Preventive Actions:

  • Regular Inspection: Schedule regular inspections of the toothed chain based on the manufacturer’s recommendations and the chain’s operating conditions.
  • Replacement: When signs of wear or fatigue are detected and approach the manufacturer’s wear limits, it’s time to replace the chain. Continuing to use a worn chain can lead to premature failure and damage to the machinery.
  • Proper Lubrication: Ensure the chain is adequately lubricated as per the manufacturer’s guidelines. Proper lubrication reduces friction and wear, prolonging the chain’s life.
  • Correct Tension: Maintain the proper tension in the chain. A loose chain can accelerate wear, while an overtightened chain can stress the components.
  • Address Misalignment: Properly align the chain and sprockets to prevent uneven wear and stress on the chain.
  • Keep It Clean: Regularly clean the chain and remove dirt, debris, and contaminants that can accelerate wear.
  • Use Quality Chains: Invest in high-quality toothed chains from reputable manufacturers to ensure durability and performance.

Conclusion: Identifying signs of wear and fatigue in a toothed chain through regular inspections is crucial for preventing failures and downtime. Taking timely action, such as replacing worn chains, maintaining proper tension, and ensuring adequate lubrication, will help prolong the life of the toothed chain and maintain the efficiency and reliability of your machinery or equipment.
