Why should a chain drive be used over a belt or rope driven drive? State pro`s and con`s.

The advantages of using a chain drives are: > In a chain drive no slip occurrence takes place.
> The chains take less space as compared to rope or belts as they are made of metal and offer much strength.
> The chain drives can be used at both short and long ranges and they offer a high level of transmission efficiency.
> Chain drives can transmit more load and power as compared to belts.
> A very high speed ratio can be maintained in one step of chain drives.
Some of the cons of using a chain drive are: > The cost of producing chain drives is higher as compared to that of belts.
> The chain drives must be serviced and maintained at regular intervals and henceforth their cost of ownership is high comparatively.

Both the chain drive and belt drives have separate application, belt and rope drives can be used where sliping of drive is tolerable where as chain drives are bieng used where sliping of drive should not take place

because in condition of high load(tension) the belt can be slip but chain couild not takes slip it can break but we use it according to the load.

1. low of maintinance as comper to timing belt

 

Chain drives are more durable because of their material. Chains are less prone to get loose or slipy. The only disadvantage of chain drives is that they need timely lubrication and sound somebit noisy. 

most of the belts are slliped due to having a load varation but in chaine drive it is not slip
