Diesel engine bearing common forms of damage

Diesel engine bearing common forms of damage source: this website the author: the administrator to release time: 2018 - 06 - 07 15:45:49 views: 0 diesel engine bearing the damage form of common diesel engine is a mechanical equipment, we often hear in many vehicles will have diesel engine, but in the use of diesel engine, there might be some problems, the three common damage is in the form of abrasive wear and fatigue spalling and burning-out, actually this three kinds of damage forms are connected, so now we can in order to let everyone know more about diesel engine bearing common forms of damage, the following will be presenting to you more wonderful content, please look! 1, abrasive wear: this is due to the lubricating oil with the tiny hard solids, along with the oil circulation into the clearance between the shaft and bearing, attached to the bearing surface, the formation of abrasive, cause scratches on the surface of the bearing and Nick. 2, fatigue spalling: bearing in the case of overload, eccentric wear, because of the bearing operating temperature is too high, alloy layer of uneven or alloy material's fatigue strength is too low, bearing in the impact of the oil film pressure, alloy layer is fatigue crack, the crack, crack fatigue crack to alloy layer depth direction, and to the combination of near surface along the horizontal extension, alternating with each other, causing exfoliate alloy material. 3, burning-out: as the bearing gap is too big or too small, when the lubricating oil supply interruption and supply, or bearing and shaft collar not form oil film, which in the bearing and the shaft collar half dry friction or dry friction, produce a lot of friction heat, caused by microscopic melting, adhesion, if continue to develop, will lead to bearing burning fuse. Above is we bring you the information about the engine bearing common forms of damage, I believe you also had about the three common forms of bearing damage can preliminary understanding, so I hope we can surface when using the occurrence of these problems, if happen, also want to some methods to solve, so that we can we can use for longer periods of time.
