Advantages and Disadvantages of Chain Drive over Belt or Rope Drive

Advantages and Disadvantages of Chain Drive over Belt or Rope Drive Points : advantages and disadvantages of chain drive over belt or rope drive Advantages
  1. It can be use for equally long as well as small distances.
  2. It has capability to transmit motion to some shafts by one chain only.
  3. It can be operate under adverse temperature and atmospheric situation.
  4. It gives a high transmission effectiveness (upto 98 percent).
  5. It permits high speed percentage of 8 to 10 in one step.
  6. As chains are prepared of metal, thus they engage less space in width than a belt or rope drive.
  7. While no slip takes place through chain drive, thus perfect velocity ratio is obtain.
  8. It conveys more power than belts.
  9. It gives fewer loads on shafts.
Disadvantages
  1. Chain drive needs precise rising and careful maintenance, principally lubrication and slack adjustment.
  2. Chain drive has velocity fluctuations particularly when overly stretched.
  3. The manufacture cost of chains is fairly high.
