ME100 Basics of Mechanical Engineering Module 4 :'Rope and Chain Drive'

Rope Drives

•       Rope drives are used for transmission of large amount of power over long distances.

•       Wire ropes are extensively used in

•       elevators,

•        mine hoist,

•        cranes,

•        conveyors,

•        lifting tackles

•       suspension bridges etc.

Advantages

•        A number of drives may be taken from one driving pulley.

•       For a rope drive, groove angle of the  pulley is usually 45^o

Commonly used  rope drives are

•       Fiber ropes

•       Wire ropes

Chain Drives

Chain drives are used in

•       Bicycles

•       Motor cycles

•       Machinery

•       Rolling mills

•       Conveyors

Advantages

•       It can provide nonslip drives

•       It provides high efficiency

•       Offers less load on shafts

•       Occupies less space

Disadvantages

•       High cost

•       More weight

•       Velocity fluctuations due to stretching during use

•       Needs accurate mounting and maintenance

•       Lubrication is critical

•       Chain does not perform well on applications requiring precision positioning
