What to do if the sliding bearing of the concrete mixer is damaged? In fact, the early damage of the sliding bearing of the mixer is more common than the bearing burning, so it is very important to prevent the early damage of the sliding bearing.
Under the repeated action of the cylinder pressure impact load, the surface of the sliding bearing undergoes plastic deformation and cold work hardening, partially losing the deformation ability, gradually forming stripes and expanding, and then with the falling off of the wear debris, a cavity is formed on the stressed surface.
In general, when pitting occurs on the bearing bush, the pitting first occurs, and then gradually expands, leading to the interface cracking of the alloy layer. The crack propagates parallel to the interface until peeling.
The main reason for cavitation of sliding bearing is that the sudden change of the cross section of structural elements such as oil groove and oil hole leads to the strong disorder of oil flow, forming bubbles in the disordered vacuum area, and then cavitation occurs due to the collapse of bubbles due to the pressure rise.
The above is a detailed introduction to the automatic mixer, and I hope it will be helpful to you. If you have any questions, please contact us. We will provide you with professional service http://www.uteplidom.com/
