Two Fatigue Wear Mechanisms of the Type of Stone Crusher Liner

First we need to know what is fatigue wear? Usually the fatigue wear process of the jaw stone crush machine is the process of crack generation and expansion! Therefore, we can determine the mechanism of fatigue wear according to the position of crack generation in the following two cases.

Sliding contact fatigue wear of the jaw stone breaker liner. The two rolling contact objects of the jaw type stone crusher have a large shear stress at 0.786b (6 is the half width of the planar contact area) below the surface of the jaw stone crusher. The plastic deformation of the jaw-type stone crusher is severe, and the repeated deformation under the cyclic load causes the material to be partially weakened, and cracks first appear in the jaw stone crusher. Under the combined effect of shear stress caused by sliding friction and shear stress caused by normal load, the large shear stress is moved from 0.786b to the surface of the rock crusher to form rolling fatigue wear. The depth of the peeling layer is generally 0.2-0. 4mm.

Rolling contact fatigue wear of the jaw stone breaker liner. The rolling bearing and transmission gear of the jaw type stone crusher have the phenomenon of pitting and falling off between the surfaces of the rolling friction pair, which are caused by the rolling contact fatigue wear of the jaw crusher. It is characterized in that after a certain number of cyclic contact stresses, pitting or shedding occurs, leaving acne-like pits on the surface of the friction pair with a depth of 0.1-0.2 mm or less.
