(1) The belt is an elastic body that can alleviate load impact and operate smoothly without noise.
(2) Overloading will cause the belt to slip on the pulley, thus protecting the entire machine.
(3) Manufacturing and installation accuracy is not as strict as meshing transmission, maintenance is convenient, and lubrication is not required.
(4) The length of the belt can be increased to adapt to working conditions with larger center distance.
