What are Chain Drives?

Before we look into the advantages and disadvantages of chain drives, it's a good idea if we understood what they really are.

A chain drive is simply defined as a mechanism that transmits power mechanically from a machine's engine to its wheel through an endless rotating chain.

Examples of machines that utilizes the chain drive mechanism include tractors, bicycles and chain saws.

Note: Based on the respective uses of the chain drive, they can be classified into three types. These are:

  • Power Transmission Chains
  • Load Lifting Chains
  • Hauling Chains

Please read the Introduction, Categories and Types of Chain Drive here.


Advantages of Chain Drives

  1. They have a very high efficiency (at about 99%).
  2. They transmit larger load with higher power than belt drives.
    Please read on Belt Drives here.
  3. They work fine in at different temperatures including wet conditions.
    You can read on the Concepts of Heat and Temperature here.
  4. They produce less stress on the shafts. This is because they make use of sprockets which are lighter than pulleys (in belt drives).
  5. Their rate at which they are checked for maintenance is low.
    Please read on Maintenance and Types of Maintenance here.
  6. They are positive non-sail drives.
  7. With regards to the size of the machine, they occupy less space and are more compact when compared to belt drives.
  8. They can be used for both long and short distance activities.
  9. They are not prone to catching fire.
  10. They can withstand abrasive conditions without being cut.
  11. A single chain can drive a number of sprockets.
  12. Compared to gear drives, they are simplier and less expensive.


Disadvantages of Chain Drives

  1. They are expensive than belt drives.
  2. They require lubrication for optimum performance.
    You can read on the Concepts of Force and Motion here.
  3. The driving shaft and the driven shaft must be always perfectly aligned.
  4. Their alignment must be precise if they are to work effectively.
  5. Most generate noise while in operation.
  6. They are not suitable for non-parallel shafts.
