Question:

What are the main failure modes of plain bearings?

What are the main failure modes of plain bearings?

Answer:

(3) for low grade bearings, the failure form is plastic deformation, and the static strength calculation should be carried out without plastic deformation.
(2) for high speed bearings, the overheating of the work surface will also cause failure. Therefore, besides the life calculation, the limit speed should also be checked.
There are three kinds of failure modes in rolling bearings: fatigue pitting, plastic deformation and wear. Calculation criteria:(1) for the bearings of general speed, fatigue pitting is the main failure form, and fatigue life is calculated according to the fatigue strength.
