What are the main failure modes of belt drives?
Skid:When the work load exceeds the maximum effective tension of belt drive, belt and a small belt pulley along the working face relative sliding, can not transfer the movement and tension, resulting in transmission slip failure.
The main failure modes of belt drive are skid and fatigue failure.1, with fatigue fracture:The stresses on any cross section of the band will change as the belt moves. When the stress cycle reached a certain number, that is, after running for a certain period of time, the belt appeared in the local fatigue crack delamination, and then appeared loose or even fracture, resulting in fatigue damage, loss of transmission capacity.
There are 2 main types: skidding and fatigue failureSkid: generally, when the force of transmission is greater than the sum of the friction between pulleys, overload, skid, transmission failure will occur.Fatigue failure: the belt cracks under the repeated action of stress, delamination, loosening, and fracture.
