As the main bearing bush and connecting rod of sliding NTN bearing; the most common problem in the application is the peeling or burning of the wear-resistant alloy layer; and the early wear of the bearing. If the diesel engine passes short-term work; the outer surface of the bearing bush is agile or severely worn; Most of the reasons are not in the bearing shell itself; firstly due to the application of conditions or poor cooperation parts or skills, there is a query data; the reason for bearing damage is 44.9% is formed by impurities; 13.4% is installed Bad; 12.7% is too concentric; 10.8% is smooth; 9.5% is overload; others are corrosion and other factors.
The diesel engine is in the process of starting and parking; the NTN bearing is often in a critical smooth condition; the oil film can be connected continuously; the friction surface is directly touched. Even if the diesel engine is in normal operation; due to unstable load, etc.; the journal and the bearing are also difficult to adhere to. And the liquid that is not connected is smooth. Others; the new diesel engine fails to completely remove the molding sand and iron filings during installation; it can enter dust and dirt during the working process; it is also the accelerated wear; the primary cause of the formation of the lava.
The shedding of the NTN bearing is mainly due to fatigue damage. The size and direction of the bearing are changed with time; when the load is unstable; the oil film of the oil film is not evenly adhered to the bearing friction; In the case of minimum oil film thickness; high temperature occurs in part of the bearing surface; greatly reduces the fatigue strength of the alloy layer. Others; NTN bearing itself is poorly fabricated and installed; it is also the direct cause of the alloy layer falling off.
In addition to wear and tear; the corrosion of sliding NTN bearings is also a significant problem; this depends primarily on the quality, temperature, pressure and bearing load of the oil. The high load of the bearing is the simplest to show corrosion; while the smooth oil is transformed at high temperatures. The resulting organic acids and sulfides are the direct cause of bearing corrosion.
The burning of NTN bearings; that is, the so-called "burning tile"; the primary reason is that the gap is over.
