Why are the engines almost all rubber belts?
The use of rubber belts also has a role in ensuring the safety of the transmission equipment, such as wheels, bearings and engines, and is easy to change and cheap.
The main reason for the belt is to prevent overload, because when the load is too large, the belt can slip, and also can start slipping, reducing the starting shock.
All kinds of driving methods have their own advantages and disadvantages.Sprocket, chain drive - transfer speed is limited.Gear transmission --- the transmission distance is limited and the noise is great.Belt drive - smooth transmission, quiet, easy to implement, low cost.
