INTRODUCTION OF BELT, CHAIN& ROPES

IN the previous post we have seen about power transmission through different types of gear pairs, but when there is need to transmit the power our long distance in this case clothes are not useful. In these very cases BELT DRIVE, CHAIN DRIVE, ROPE DRIVE are used. In this post, we will learn basics about belt, chain& rope drives. Let’s get started.

                              

Ø As we say in beginning, ropes, belts& chains are used where the distance between the shafts is significant. For small distance gears are preferable.

Ø Ropes, belts& chains are the flexible types, so they bent easily when required.

Ø The flexibility of straps and ropes are due to the property of their material whereas 

chains have some small rigid elements having relative motion between the two parts.

Ø Belts and ropes transmit power due to friction between them and pulleys. If the power transmitted exceeds a certain limit (that limit is a force of friction), the belt or ropes slip over the pulley.

Ø Belts and ropes are strained during motion as tensions are developed in them.

Ø Owing to slipping and twisting action, belts, and cables are not the positive type of drives, their velocity ration is not constant. On the other hand, chains and gears have constant speed ratios.
