Chain drives vs belts Isaac Gendler
One of the most heated decisions a Mechanical Engineer must make is to either utilize a chain drive or a belt for a rotary power transmission system. Chain drives lose much less energy to friction, making them more efficient. Chain drives are also usually stronger, and can slip around geared systems much more smoothly. Chain drives are also usually much narrower, making them easier to wrap around smaller objects. The drawbacks of chain drives is that they often have greater inertia, they can have a non-uniform velocity which can cause entanglement, and can be subject to vibrations.
