    - Belt drives cannot be used in applications where constant speed ratio is needed.

    - These drives have short life compared to gear drives.

    - These drives cannot be used at high speeds, when centrifugal effect reduces power transmitting capacity.

    - These drives have low power transmitting capacity.
