The main disadvantage of the belt drives and the rope drives is that the velocity ratio does not remain constant, but varies on account of slip. Engineering is the process of making the best decisions within the given parameters of knowledge, time, budgets and other available resources. Belt and pulley systems also offer design advantages with respect to either chain or gear drives. Gears can operate at higher speeds and transmit more power than chains or belts. Vbelt selection its a veritable cinch machine design. Determine allowable forces and torques for flexible drive systems, along with the necessary sprockets or sheaves.
Since chain drives are positive drives there is no slip, hence the velocity ratio will remain constant chain drives are suitable for small centre distances and can be used generally up to 3 meters but in special. They may be used as a source of motion, to efficiently transmit power, or to track relative movement. Belt drives are not as noisy as chain or gear drive systems.
